Welcome to our featured review on the best air purifiers currently available.

Air purifiers are ideal for removing common indoor microns and allergens that include dust mites.

Allergens like dust mites can cause allergies, bronchial asthma, and sinus disease.

Vacuuming isn’t always good enough when it comes to ridding your home of these allergens and they are especially bad if you share your home with pets.

Pets bring about pet odors, urine stains, and pet dander which can also cause a person’s allergies to hit strong and cause respiratory distress.

But Air quality is not something most individuals spend a lot of time thinking about.

Best Air purifiers are designed to purify

and freshen the air in your home while removing these allergens.

Best Air purifiers of 2018 consist of a filter,

air change rate, CADR (Clean Air Delivery Rating system), and other optional features such as automatic sensors.

1.Boneco p500 Carbon Best Air Purifiers

BONECO Air PurifierThe Boneco P500 Air Purifier features a sleek design which can fit comfortably into any area of the home.

Unlike most of its competitors, the p500 is clearly built to be beautiful.

It’s a sleekly designed machine of excellent manufacture.

Remove the magnetically attached front panel and you’ll note the filter itself is remarkably large relative to the machine’s size, offering plenty of purifying potential.

It’ a pleasure use, too.A standout feature is the display brightness, which dims or brightens depending on the ambient light.

You can either leave the machine in Auto mode, or operate it manually by cycling through the five available speeds with the press of a button.

The unit offers the power for collecting allergens in a space of up to 222 square feet, but it is ultra-quiet so you hardly notice when it’s on.

The P500 comes with an allergy filter (A501) which is specifically designed to collect dust, pollen, hair, bacteria, unpleasant odors, etc.

I experimented with putting the unit near the kitchen, and noticed a considerable decrease in the time it takes for odors associated with cooking and the trash can to dissipate.

In addition to the practical features, the P500 has convenient settings for auto-mode and sleep-mode, if you don’t want to worry about turning the fan on and off.I have also used the P500 in the bedroom and living room, and again, you really do not notice the sound.

I do have seasonal allergies, and I noticed fewer symptoms after putting the unit in the bedroom for the evening (mainly I wasn’t feeling as congested when I woke up).

  • Incredibly easy to put together (3 parts and it comes with the allergy air filter)
  • Very quiet, really cannot even tell it’s on
  • Sleek and modern design
  • Really easy to use – simply turn on the power button and select the auto option or manually increase the fan option
  • You can tell when the unit is working, because the display shows red when the air is being exchanged and filtered
  • Option for putting a fragrance in the back of the unit (if that’s something you’re interested in)
  • It is recommended that you replace the filter at least once a year, and the replacement filters are $99.00 each
  • Pretty expensive, but reasonable in comparison to other filters
  • It would be nice to if the air sensor display provided more details about the air quality in the home (for example, if the purifier was working to reduce dander or dust from an animal vs. just cleaning the air after you cook a meal)

All in all the biggest and only issue is the price, and if you can swing it this is the unit you want.


2.Winix 5500-2 HEPA Best Air Purifiers

I’m apparently the only person writing a review for this that’s not a Vine free product review, but it looks like they have the product pretty well summed up!

This Winix air purifier is a top rated air purifier because it uses a patented PlasmaWave technology not found in other air cleaners.

This innovative feature offers the same air cleaning advantages of an ionizer, but doesn’t produce harmful side effects or ozone.

PlasmaWave is the safest technology of its kind on the market and for the price this is the best air purifier under $200.

Not only does it use a True HEPA Filter to remove 99.97% of dust and allergens from your home, but the PlasmaWave technology goes one step further to eliminate other toxic contaminants.

This feature is a safe method of killing bacteria and viruses that doesn’t irritate allergies or asthma symptoms, something that ionic air cleaners are guilty of producing.

A Carbon Filter is also included to help reduce smells and smoke.

The most notable feature, however, is that it includes a smart sensor that monitors the air quality within a room and automatically adjusts itself to maximize the air cleaning power.

  • The filters are stupidly easy to swap in and out (Initial setup was around two minutes to peel off plastic protective films and put everything together).
  • The unit is nearly noiseless. On low or Sleep mode, I couldn’t hear a fan at all over the ambient noise of a home.
    I’ve caught myself on multiple occasions actually waving my hand over the unit to double check that it’s still running – it’s that quiet.
    I’ve spent four nights now with it on Sleep mode inches from my head and it’s so quiet I’ll hit it getting out of bed.
  • Medium has about the same noise as a normal desktop computer – it’s something you can barely detect, but it’s a soft whirr that quickly blends into the background.
  • High picks up the noise to a detectable level, but if it’s behind a corner or otherwise not in direct earshot, quickly blends into the background.
  • Turbo, as called out in other reviews, is fairly noisy, but I’d put it at about the level of a standard HEPA unit on Medium.
    You’ll easily hear it, even in a different room. I keep Turbo mode to setting in a room when I leave the house or will have the doors closed.
  • The remote control is nifty, but a bit unreliable. I’ve found I have to hit buttons several times before it “wakes up” and starts controlling the unit.
  • There’s a great little carrying handle on the top of the unit, and with the sleek boxy shape and low weight it’s very easy to move from room to room
  • After a spring cleaning, the shower had a very pungent chemical odor from cleaning agents.
    Setting this down on Turbo and shutting the door to the bathroom for a few hours did an excellent job of clearing that up.
  • The cord is fairly short – I’d say about 5ft? This could be considered a pro (less to manage), but if you plan to have it anywhere but near an outlet you’ll need to run an extension.
  • Remote is a bit finnicky and doesn’t always work, you may have to mash it a bit before it starts sending commands
  • Sleep mode only lets you run it on Low, so if you don’t mind the slight extra noise of Medium (or prefer it as a white noise generator), you’ll have to put up with the bright lights or find a way to cover them up.

I’d say this is a very solid air filtration unit.

The charcoal filter does a good job on odors, and the loose mesh pre-filter is FANTASTIC for pet hair.

Easy to clean and replace, and prevents hair and dust bunnies from clogging up an expensive charcoal or HEPA filter.



3.Honeywell HFD-120-Q QuietClean Tower Air Purifier

The HFD-120-Q is a very quiet unit. I have tried HEPA and HEPA-style filters in the past, as well as Ionizers.

They are either noisy, ineffective, or both. The HFD-120-Q is very quiet and flows a lot of air even at the low speed.

I find myself using the medium setting the most, and it has enough power to flow air across my entire house.

The power consumption is advertised as 43W, but I used my Cyberpower UPS meter to check it and it registered only 36W.

This was in the low, medium, and high settings which suggests it uses some type of resistive setup to reduce the fan speed for low and medium settings.

I wouldn’t recommend keeping it right next to you as you sleep, because it isn’t that quiet.

It is quiet enough to keep it outside in the hallway as you sleep.

There are 2 types of filters on the machine.

One is a foam pre-filter, and there are 2 IFD filters that are washable.

The ionizer charges pollen and dust so that it can be easily cleaned up rather than airborne.

I just know that with seasonal allergies, the histamine effects are significantly reduced when I keep the HFD-120-Q active.

  • Quiet
  • Occilates
  • Three Speed Settings
  • Collects Large Amounts of Dust
  • Easy to Clean
  • Blows Fresh Clean Air
  • Low Energy
  • Washable Filters
  • Short Occilation
  • Short Power Cord and Must be 4 Feet From Wall

Overall: 5/5 stars, energy saver at 36W, filters a lot of air, runs very quiet, and uses washable filters.



4.AIRMEGA 300S App Air Purifier

This AIRMEGA product ranks high on the list of best rated air purifiers because it offers something not many other devices provide – Smart Enabled Features.

Initially I thought it was rather on the expensive side, but after some research I’ve learned that Coway is a big company that is committed into making only air purifiers & water filtration devices, with over billion dollars in revenue!What makes this product so popular is the fact that you can control every aspect of it from your iOS or android device.

It also has a real-time air quality monitoring system so you know exactly how fresh or polluted the air is around you.

Also the wireless app options (I’m into ‘smart home’ craze) enticed me and I figured that the risk is low since I can always return the product if I wasn’t happy with it.

Have I ever returned it?

This machine uses an advanced set of air filters – True HEPA and Activated Carbon – that are capable of capturing 99% of volatile organic compounds (VOCs) and 99.97% of all other pollutants.

This rating is one of the best in the industry.

  • Connectivity: Unlike other air purifiers out there, which is blue tooth enabled, this one is TRULY Wireless
  • Thoughtful: There is an option to turn off the light, so that it won’t bother you at night
  • Pollution level indicator: Color changes according to the pollution level.
    When I was cooking fish in the kitchen, it automatically triggered to go on ‘max’ speed and made smell go away faster
  • DESIGN: this thing is just so darn pretty. It looks like it came from the future
  • Performance: It is ultra quiet, and uses Charcoal Filter to eliminate smell
  • App: while simple & useful, could be more intuitive and provide more options other than setting up ‘timers’ & ability to turn on & off


Design is thoughtful & beautiful, and I truly believe there isn’t any other air purifiers out there that offers same type of specs & features.


5.Winix WAC9500 Air Purifier

All in all, for the price of the unit, functionality, quietness, and effectiveness, I don’t think you can beat this.


I shopped around a bit but units with comparable functions and filter quality were generally $100+ more expensive or didn’t have a HEPA filter.


I would definitely recommend this for either a large bedroom or a small-medium sized family/living room or kitchen.



  • When you run it on sleep mode, it is extremely quiet.
  • The remote is nice.
  • In sleep mode, it would be nice if the lighted display turned off completely (we like it really dark when we sleep).
  • I wish the cord was just a bit longer.
  • When you turn it on, it goes through a cycling process that takes about 4 minutes to complete. This is supposedly so that it can detect the levels of both odor and allergens in the air.If you leave it on auto-pilot, it will adjust the fan speed to the level of contaminants when the cycling process ends, but since I prefer to set it myself, waiting 4 minutes so that I can put it on the speed I want is a little inconvenient.

All, in all, this is an excellent machine, very well built, and it is WHISPER QUIET.



6.Honeywell HPA300 Air Purifiers

Honestly, it blends in so well with the media center that no one has commented on it.

Unlike most large air purifiers, the Honeywell HPA300 is quiet and has a low-profile design.

However, it’s missing many of the features you find on other models.

Overall, the HPA300 is more effective at removing indoor pollutants than our top pick from Coway, which is evident in its high CADR scores, particularly the one for dust.

TheHoneywell HPA300 has a simple, effective design and is more affordable than the Coway, though not by much. Although we tested cheaper air purifiers, their cleaning effectiveness and CADR scores were too low to be considered a better value than this Honeywell unit.

This air purifier has a dust CADR of 320, which is one of the best scores of the models we tested – only the Whirlpool Whispure has a higher score.

It also removes smoke particles better than most air purifiers, with a CADR of 300. Its pollen CADR score is average for the air cleaners we tested.

This unit is effective in rooms up to 465 square feet, making it the second most powerful air cleaner we tested. In addition, it can make five

air changes an hour, the most in our review, by circulating a room’s air once every 12 minutes.

The Honeywell HPA300 performs well, but it keeps costs down by not having convenience features such as an auto mode that adjusts settings based on a room’s air quality, a shut-off timer or a remote control.

These are nice to have but aren’t necessary,and the HPA300 does well enough without them. However, it has an excellent five-year warranty, which the longest available among air purifiers.It is relatively quiet, and we save the turbo setting (much noisier) to night time.

  • Handles on the side make it easy to move
  • Controls are very easy to use and dimmer is a plus
  • Air flow is from the top and very strong.
  • Turbo is great for when starting up and then allergen/general clean for maintenance.
  • Clears entire 350 sq foot room
  • Very loud on turbo
  • No remote control
  • Black color/design shows any dust or dog hairs that get attached to the front

Honestly, it blends in so well with the media center that no one has commented on it.

7.Alen BreathSmart Customizable Air Purifier

This Alen air purifier completely removes all smells from the area.

It works so well as to remove candle smells as well.

They make about five different types of filters.

As I said there are about five different types of filters you can buy for specific conditions.

They also make different colors for this air purifier to match the ambience of any room.

I have a Wood Gain Cover in family room that blends right in. It’s hardly noticeable as far as the sound it makes and when the unit turns on high, it sounds like white noise… by no means a mechanical sound.

  • Sound-gives a pleasant white noise hum that I find neither too loud or soft.
  • Price – worth every dang penny
  • Performance – Cleans my 1200 sq ft apartment (no walls, just one big loft) with no problem
  • Size – It’s no small thing but even at its size, the design of the unit makes it easy to tuck against a wall and it doesn’t feel obtrusive.
  • Filters – not cheap but if your buying a purifier of this scale then you understand its need for a high performance filter.

The unit is very intelligently made as it has an auto mode, low medium and high which adjusts itself to the changing conditions in the room. There’s also light tells you when to change the filter

8.OION B-1000 Ionic Air Purifier

OION best air purifiers

When considering the purchase of an air purifier, please consider what you wish to accomplish before making your purchase.

Simply put, smoke particles can be as small as .01 microns and it does no good to use an air cleaner that can only clean down to .3 microns (or larger).

The only effective (reasonably-priced) alternative solution are these Ionic type air cleaners that are not only able to collect such small particles but also produces fresh, clean-smelling air that further reduces the smoky odors.

While these types of air cleaners are not capable of filtering a large volume of air (like the larger HEPA filters – especially the really big ones), this unit has a small two-speed fan that does improve the air flow compared to units that do not.

Lastly, this unit will definitely save you money over time because you are able to clean the collector plates instead of replacing the various filters (some can be as much as this unit and require replacement every 6 – 12 months).

So again, please think of what you are trying to accomplish beforemaking your investment.

  • OION B-1000 is UL and ARB approved
  • Permanent filters reduce operation cost
  • Remarkably silent operation
  • Blue LED light might disturb at night

Advice: For normal folks who are getting rid of dander and normal allergens, washing the filter a couple times a week is probably ok. Smoker buddies? At least once a week.


9.Biota Bot MM208 Air Purifier

Biota best air purifiers

First off, I have to say the product packaging, design and craftsmanship are 5 stars!

I have put the Biota Bot through some tests and am very impressed.

My basement has always had a faint, musty smell so I ran it therefor the first 2 days.

A noticeable difference for sure.

In the kitchen I set it on Auto Mode for a couple of days.

The top of the unit has a ring around it which changes to purple or red when the air quality is poor.

It increases the fan speed automatically and runs until the air is cleaned.

It’s a nice size, not too big or too small.

I move it into the bedroom at night and run it on the low fan speed.

This is great for white noise while sleeping.

I’m giving the Biota Bot two thumbs up!! Great Product.

  • it had all the stages of filtration I was looking for
  • American made (which many weren’t)
  • has a sleep function that turns off the display lights/very quiet
  • sleek design
  • reasonably priced replacement filters
  • Price

My unexpected favorite part is the auto setting which ramps up the filtration if it detects poor air quality.

10.Enerzen Commercial Ozone Generator Air Purifier

Enerzen best air purifiers

The unit arrived well packaged and was brand new, and a very brief test produced the strong smell of ozone, so I gave it a try. Amazingly, it worked fine and the shed odor iscompletely gone after 1 treatment of 80 minutes.

It was well worth the money. The Enerzen unit really exceeded my expectations.

Although the unit is the kind that requires replacement of ceramic plate after about 5,000 hours of use, that should be more than enough time to deodorize almost everything imaginable and replacement plates can be purchased.

The Ozone it emits is very strong stuff, so you can’t stay in the room while the unit is operating, but after an hour of airing the room, it will smell fresh and ready to occupy.

I found no lingering odors at all from the unit, although the unit does have the usual “new electronics” smell that disappears after a few days or so.

  • The ozone output is a consistent 14.3ppm @ 80 cfm = 4,157 mg/h average throughout the entire treatment process.
    When I monitored the ozone output with meters at job sites,the ozone output fluctuated between 4,100 mg/h and 4,200 mg/h, which is more than it is rated for.
    Other Amazon units, both different and similar in appearance, couldn’t maintain the steady output needed to properly treat an area and many were weaker than advertised.
  • The fan is strong and the heat sinks work well enough that the ozone output doesn’t cut out.
    We’ve tried open bare units with no cases because they were cheaper for greater ozone output.
    However, the lack of a fan and heat sinks on these type of units caused the parts to overheat stopping ozone production mid treatment, resulting in us having to retreat the area.
  • The internal parts are modular, inexpensive, and available. So far, I’ve had to replace the ozone plates a few times, but we always got close to or exceeded the rated usage hours.
    Previous Amazon purchases with similar looking units to the Enerzen had a usable time up to several thousand hours less than advertised.
  • The units are cheap enough that if anything major goes wrong, we can just replace them rather than repair them similar to printers in our office that say replace the drum unit for $60 when a new printer only costs $90.
    When our 7,000 and 14,000 mg/h had issues some of the replacement parts were over $150, so it now makes more sense for us to use several Enerzen units to obtain a similar effect.
  • The units start to make louder than normal buzzing noises after 40,000 hours of usage. We have had more expensive units do this after 55,000 hours.
    The units will continue to work, but can become a nuisance if you are going to use the units within earshot.
    Pro tip: only use ozone generators in well sealed areas and never occupy the same space or your lungs will regret it very quickly.
  • The cord is only 5 feet long. Many higher end 14,000 mg/h units will come with a 12 feet long cord.
  • There are no wheels on the base. Many higher end 14,000 mg/h units will come with wheels on the bottom making them more mobile.
    However, I guess the Enerzen units don’t weigh nearly as much as those larger units.

The unit destroys odors at the source using Ozone instead of filtering out odors like the usual air purifier, and it is worth repeating that people need to evacuate the room while the unit is operating because Ozone it produces is intense.



Do You Know Air Purifier? What is HEPA Of The Best Air Purifier ?

An air purifier is a machine that helps purge the air of particulate contaminants.

One of the situations that really benefits from a air purifier is a home with a pet or multiple pets.

Homes that have a smoker or used to have a smoker will see a great difference as well.

Air purifiers will also help collect and break down odors therefore removing them from the air.

Air purifiers won’t completely eliminate odors but it can remove many of the unpleasant ones which is nice for people who have a sensitive sense of smell.

Purified air is simply air minus all the particulate components such as dust, pollen, dander, etc.

Air purifying machines accomplish this task by using a fan to force air through a filter array.

The filter collects and traps all the particulates while letting the air itself flow back into your home.

However, it is important to note that this does not mean your air is 100% safe.

Some gases or other volatile organic compounds a well known one being formaldehyde could still be hiding out in your air.

There are some purifiers come with additional equipment that will remove these harmful gases.

Other than that, some forms of molds and dust mites remain in an environment even if the air is clean and must be removed at the source such as your carpet.

All in all, having an air purifier is going to still make a significant difference in your air quality.

The fact remains us humans do a lot of breathing. It is sort of an important part of our survival.

Particulate matter that is highly concentrated has been shown to cause lung conditions, respiratory issues, and aggravate existing health problems like chronic bronchitis and asthma.

Extremely fine particles (less than 2.5 micrometers in size) are particularly dangerous because they can get into the deepest tissues of the lungs.

That is why HEPA filters have become so popular in air purifying systems.

HEPA stands for high efficiency particulate absorption.

It is a strict government manufacturer standard an air purifier machine must meet to be rewarded with a HEPA certified label. To qualify for the label, the air purifier’s filter must remove 99.97% of particles in the air that are 0.3 micrometers or larger.

For an idea of how small that really is a human hair is actually 70 micrometers in width.

Basically, if an air purifier has a HEPA rated filter, it in a probably a top model.

If you’re going to spend money a lot of money on an air purifier a machine that has a HEPA filter is a must.

As a comparison, non HEPA filter air purifiers remove about 75-95% of particles, sometimes less.

While not as effective as an air purifier with a HEPA certified filter, it is certainly better than not having one at all.

Furthermore, non HEPA air purifiers are generally much less expensive.

The production costs of HEPA air purifiers are much higher than that of non HEPA.

As a general rule of thumb, HEPA air purifiers range from about $200-$300 while other models can be had for $50-$200ish.

Air Purifier-List of Airborne Particles:

  • Pollen
  • Spores
  • Dust
  • Smoke
  • Mold
  • Bacteria
  • Viruses

As a side note, if you aren’t ready to invest in an air purifier there are a few common-sense steps you can take to keep your home’s air clean. Vacuuming often and banning smoking indoors are two very big steps that will cut down on indoor air pollution. You can also minimize the use of wood fires, candles, and test your home for radon gas.You’ll want to use the exhaust fans in your kitchen, bathrooms, and utility rooms often. If you can help it don’t store chemicals, solvents, and other pesticides in your house. Of course, make sure you’ve got those carbon-monoxide alarms on all floors of your home.

HEPA FilterOzone (Ionizer) TechnologyUltraviolet LightActivated Carbon FilterCADR

HEPA stands for high-efficiency particulate arrestance.

A air purifier filter with HEPA certification means

that air purifier removes nearly all air pollutants and irritants (99.9%).

This type of filter is capable of collecting extremely tiny airborne particles.

The HEPA standard was developed by the US Department of Energy.

This is the same type of filter in vacuums that traps dust.

Some air purifier machines double as air fresheners.

They generate Ozone which to the human nose is a sweet smelling fragrance.

Most critics of these machines say to stay away

from them because Ozone has been shown to be a lung irritant to some individuals.

Probably the best thing to is to stay away from models that do not have a switch to turn this feature off.

Ozone and some VOCs can have chemical reactions whose byproducts may be harmful to your health.

This is a relatively new technology that some manufacturers are integrating in their machines.

These machines use ultraviolet germicidal irradiation (UVGI) which is effective at killing germs.

While in general it looks like a promising technology for air purifying,

the effectiveness in small portable air purifiers may be limited.

This is because air quickly passes through these machines so the exposure to UV light is very short.

This technology therefore may be better suited to commercial applications.

This technology is incorporated in some air purifiers to add a chemical filtration component to the machine.

These chemical sorbent filters are constructed using activated carbon or sometimes zeolite.

Both of these materials are great at absorbing odors, some gases, and VOCs.

The only issue is that you need to stay on the ball when replacing these filters.

If a filter becomes saturated it will not only stop removing the bad guys, but actually start releasing them instead.

This acronym stands for clean air delivery rate which delineates the max square footage recommended in which to use the air purifier.

It also refers to how fast the air purifier can remove the three most common air pollutants:

smoke, pollen, and dust. The higher the value, the faster the machine can filter the air.

In this section, you’ll find some of the common terms associated with air purifiers.

You Should Know Before Buying Best Air Purifier

There is a wide range of prices when it comes to air purifiers.

Like many things, the models that are actually effective are expensive upfront.

The silver lining is that the best models usually have lower operating costs

and replacement filters are easily available and cost a bit less.

Though there are many claims about air purifiers

having a dramatic positive impact on people’s health the data so far is not definitive.

The human body is a complex system and it can be very difficult to match cause

and effect in a complicated environment with so many variables.

Nevertheless, the average person spends 87% of their time indoors,

and caring about the air quality indoors makes a lot of sense.

Perhaps the best thing to do is to judge for yourself personally

if it makes a difference after running it for awhile.

Portable or Whole House Air Purifier Situations where it makes the most amount of sense to buy an air purifier is

if you are sensitive to pet dander and own a lot of pets,

have bad allergies, do not have access to clean outdoor air, live near busy roads/power plants/factories, or have any type of respiratory affliction.

For pretty much everyone else, it comes down to whether or not it will give you a peace of mind that is worth the price of buying and maintaining an air purifier.

If you have lived your whole life without trouble you’ll probably be okay without buying one.

They are expensive machines and have ongoing costs such as filter replacements and not to mention the added electricity cost on your utility bill.If you are interested in juicers you can read this article:Top 10 Best Juicers Buying Reviews
