After 16 hours of research evaluating 87 products, we picked GermGuardian 3-in-1 Air Cleaning System with True HEPA, UV-C and Odor Reduction as our top choice.

You'd be amazed--and probably disgusted--at what you're breathing in! Research shows, indoor air can actually be deadlier than outdoor air. 

This is crazy:

There are billions of particles floating in the air: dust, dirt, pollen, pollution, germs, bacteria, food particles, oils, and so much more. With every breath, you're pulling those pollutants into your body, meaning it's a constant struggle for your immune system to fight off airborne illnesses, pathogens, and allergens.

What can you do about it? Simple: get the best air purifier available!

If you haven't studied air purifier reviews, you are at risk of buying an air purifier that is not really effective at cleaning the most harmful contaminants.

This is where a HEPA air purifier comes into play when evaluating the best air purifier options.

Air purifiers are designed to remove contaminants from your air, making it as clean and safe to breathe as possible.

If you get seasonal allergies, have respiratory difficulties, suffer from asthma attacks, or just want to clean up your air, it's a good idea to get an air purifier for your room, office, and home.

25 Bought | Save: $150 (30% OFF)

Why People Love it

  • Makes the air crisp and clean
  • App shows improvements in air quality after consistent usage
  • Tall and skinny design requires little floor space

The filter only lasts about 6 months and costs around $70 to replace. 

Details

Performance: The air purifier is designed for medium to large spaces, making it ideal for use in a family room, office, or bedroom. The True HEPA air filter will eliminate 99.97% of dust and allergens as small as 0.3 microns, and the carbon pre-filter will help to deal with odors. 

This purifier also comes built with a fan to keep you cool in the summer. And, not to worry, there are no fast spinning blades so it's safe for little fingers or paws. 

Operation: The thing that sets the Dyson apart is the Dyson Link app. Using wifi, it gives you real-time air quality reports. And, allows you to remotely control your purifier.

Another feature we love, is the ability to choose between 10 airspeed settings. The Dyson also has a night time mode and sleep timer. So you can sleep soundly without having to worry about whether or not you turned it off. 

Price: At $499, this is definitely a high-priced purifier. And, although it may seem like a high price to pay to purify one room, it gets the job done. You can actually see the results right on your smartphone.

Why People Love it

  • Excellent for heavy dust, allergens, and pet dander
  • Fairly quiet operation on lower settings; not too noisy, even on highest speeds
  • Energy Star Certified; uses less than 75 watts at highest speed

Want cleaner air, but not suffering from crazy allergies? Need a cost effective air purifier that can cover a large room (up to 350 square feet)? Well look no further than the Winix Plasma Wave.

  • 3-stage air cleaning unit removes indoor pollutants and odors
  • Built-in air quality sensor adjusts fan speed automatically
  • Energy Star approved; 1-year limited warranty

Has a plastic odor and the PlasmaWave makes a clicking noise.

Details

Performance: The air purifier is designed for spaces up to 350 square feet, making it ideal for use in a family room, office, or bedroom. The True HEPA air filter will eliminate 99.97% of dust and allergens, and the carbon pre-filter will help to deal with bad smells.

Thanks to the air quality sensor, you will always know when it's time to turn the settings up or down according to the particles in the air. If your room is filled with heavy dust or allergens, you'll need to run this air purifier on Turbo Speed to really see the results you want.

But once the air is clean, you can turn the speed down to the lower settings and keep the air fresh and free of dust/germs/allergens.

Operation: The Energy Star Certification on this air purifier ensures that you waste as little energy as possible. It consumes just 2 watts on Sleep Mode, and 36 watts on the High Speed setting. Even if you have to turn it to Turbo Mode, it only consumes 73 watts. Definitely a "green" appliance!

This isn't going to solve all your dust problems--you'll still need to vacuum and change your bedding. However, it will help to keep your air clean and breathable, eliminating the majority of floating dust, pollen, dander, and chemical particles.

The self-cleaning feature will ensure that your purifier lasts for as long as possible.

Price: At $170, this is a mid-priced purifier. It's not so expensive that it has to deliver clean room-grade purification, nor so cheap that you get low quality operation. It's an excellent value appliance for a very reasonable cost.

Why People Love it

  • Generates minimal ozone; less likely to trigger asthma attacks
  • Operates with very little noise
  • Ideal for medium to large-sized rooms; can easily handle 600 square feet

We know you're tempted to breeze right past this one, we were too. But, you shouldn't - and it's not because the price tag makes you happy. This air purifier alerts you when the filter needs to be replaced; ncludes Hepa filter, activated carbon filter, pre-filter, germicidal UV Lamp, ionizer, and electronic dust collection grid; and, clinical tests show, the Intelli-Pro outperforms the Consumer Reports Top-Rated Air Purifier.

Difficult to clean and the odor filter provides limited efficiency.

Details

Performance: This ionic air purifier is designed to not only kill off bacteria and germs, but eliminate a lot of odors and allergens. The odor-killing element is less than optimal, but you'll find it will clean your air beautifully.

Install it in a medium- to large-sized space (think dining room and kitchen, large living room, or master bedroom), and you'll have clean air in no time.

It's more than just an ionizer, but it comes with a built-in HEPA filter to ensure the cleanest air possible. With the UV lamp to kill of pathogens, you've got a clean, safe home.

There are seven types of filters, including a photocatalytic filter, an electrostatic dust collector, and a pre-filter. Dust and allergens be gone!

Operation: The unit is designed to "self-monitor", meaning it will alert you to the device's performance, let you know how clean the air is, and tell you how much dust, allergens, and pollen are in the air. Additionally, there is an indicator light to tell you when it's time to change or clean the filters.

The ionic air purifier runs fairly quietly, and you'll find that it consumes far less energy than other competing models. The sensor technology in the unit will automatically raise or lower the fan speed according to the odors and particles in the air in order to save energy. It generates less ozone than other ionizers, meaning it's safer for those with asthma.

Price: At $191, this is a low-cost appliance that gets the job done! The built-in features and multi-filter system will ensure that your home is clean and free of allergens, with as little fuss as possible.

Why People Love it

  • On the lowest setting, you can't even hear that it's on
  • Keeps the dust and animal hairs away
  • Permanent filter only needs to be vacuumed once a month

Blows out cold air when it's on.

Details

Performance: Built with a HEPA-grade filter, this air purifier eliminates 99% of allergens, dust, and particles from the air. It can filter particles as small as 3 microns, meaning it will eradicate pet dander, mold spores, pollen, and dust effectively.

It also neutralizes the strongest odors. The thing we love most about this air purifier is that it's an odor-killer, thanks to the HEPA filter. This filter is permanent and never needs replacement.

All you need to do is vacuum it clean once a month. It will remove unpleasant scents easily, leaving your house smelling fresh and clean. 

The Hamilton Beach is ideal for large sized rooms and can handle up to 160 square feet of air. That means it can purify your bedroom, office, or den. As a bonus, it comes in black or white. And, can be used vertically or horizontally to fit any space. 

Operation: If loud noises in your home drive you crazy, this is the air filter for you. The Hamilton Beach has three ultra quiet speeds. On low, it's barely heard and makes very little noise even on the highest speed setting. You can even sleep with it on.

It has a simple tower design, and it will take up very little space in your rooms. This filter also has a simple control knob so you can easily choose your speed setting.

Price: The $80 price on this Hamilton purifier is definitely well worth the investment. You get a quiet air purifier that will leave your home smelling odor-free, while also eliminating allergens from your air. 

Best Compact Air Purifier

Score 84

Why People Love it

  • Removes odors within hours
  • Perfect for small spaces (bathroom, pet area, etc.)
  • Affordable compared to other air purifiers

Makes a slight noise when on, not as effective as larger or pricier air purifiers, and can't handle large rooms.

Details

Performance: The truth is, this is NOT an air purifier designed to keep your whole home clean. It's meant to be used in extra small spaces such as a bathroom, pet area, laundry room or nursery, purifying the air only in that small space. It can handle up to 70 square feet. 

The Germ Guardian uses UV-C light technology. It's proven to kill 99.9% of germs as they pass through. While it's not ideal for those with severe allergies to dust or pollen, it is good for those who want to eliminate most of the germs and odor in their homes.

Operation: This little air purifier comes with no filter which means you never have to clean or replace it. The little 8.2 inch tall device can be placed vertically into any wall socket, making it easy to fit the space you have.

It has one power setting, and there will only be a gentle hum on this speed. 

Price: At $35, this is the cheapest air purifier on the list. It's designed to do just one job: remove ordors and reduce germs from your air. There are no frills, and it's not as efficient as the higher-priced devices on this list. But for those who want something compact and simple, you'll find no better air purifier around.

Why People Love it

  • Simple, practical air purifier with 3-stage filteration 
  • Eliminates any odor - even after cooking
  • Perfect for small spaces

Designed to purify small spaces, but unfortunately the dimensions of the Levoit aren't so small (9.7 x 9.8 x 14.6 inches).

Details

Performance: The air purifier is designed for spaces up to 86 square feet, making it ideal for use in a small bedroom or office.

The Levoit has a three stage filteration system that is truly impressive. The fine preliminary filter helps neutralize airborne bacteria, pet dander, mold & fungi.

The True HEPA air filter will eliminate 99.97% of dust and allergens. As a bonus, the carbon pre-filter will help to deal with unwanted odors. 

If your room is filled with heavy dust or allergens, you'll want to use this air purifier on High Speed. But once the air is clean, you can turn the speed down to the lower settings and keep the air fresh and free of dust/germs/allergens. 

Operation: To operate, the Levoit has five simple buttons on the top of the purifier. These buttons allow you to turn the purifier on and off, adjust the nightlight, and control the three fan speeds.

What really sets the Levoit apart from the rest, is that it quietly operates throughout the night, and has a gentle night light with two brightness settings. Not to worry though, if nightlights aren't your thing, you can switch it off. 

Price: At $90, this is a farily affordable purifier. It's not so expensive that it will drain your wallet, nor so cheap that you get low quality performance.

It's an excellent air purifier for a very reasonable cost. Keep in mind that filter change intervals are every 6 months and will cost around $30.

Why People Love it

  • Simple, practical air purifier with reliable HEPA air filter
  • Very quiet on the lower settings
  • Pre-charges the dust particles so they stick to the filter

This air purifier from Blueair is quite sexy. It's got that smooth styling that wants to cuddle up with your Apple products. 

  • Designed for rooms up to 365 square feet and to fit beautifully into your home decor
  • Highly efficient HEPASilent® technology captures 99.97% of particles 
  • Winner of Excellent Swedish Design award

Fan is very noisy on highest speed setting.

Details

Performance: This air purifier is designed to handle rooms of up to 365 square feet, with a CADR of 240 cubic feet of air per minute--making it perfect for a bedroom or home office.

The HEPASilent filter will eliminate 99.97% of smoke, dust, pollen, and bacteria particles from the air, down to 0.1 microns in size. The air purifier has an ion particle-charging chamber that will charge the particles as they pass through, ensuring that they stick to the air filter more effectively. The result: cleaner air!  

There is a detachable timer that sounds an alert if the filter is in need of changing, and changing the filter is beautifully simple. The lightweight filter is portable (weighing 33 pounds) and easy to move to any room in your house--thanks to the built-in carry handle.

Operation: On the lowest fan setting, the air purifier runs at a volume barely above a whisper. However, be warned that there is a noticeable hum if you turn it onto the highest speed. It's energy-efficient and built to last.

The device looks beautiful, and its elegant Swedish design will fit in with any modern décor.

Price: $550 may seem like a high price to pay for a filter that can only handle one room at a time, but for those who want to ensure the cleanest possible air it's a worthwhile investment.

Why People Love it

  • Noticeably decreases dust and allergens
  • Can be programmed to run automatically; remote-controlled

Details

Performance: If you're looking for a quality air purifier to eliminate dust from your home, you'll love the HealthPro Plus! It's designed for whole-home use, and has a very high Clean Air Delivery Rate.

It's built using a hospital-grade HEPA filter which will eradicate 99.97% of the dust and particles in your air. You'll never have to worry about indoor allergens, dust, and germs again.

Asthmatics and those who suffer from seasonal allergies will benefit from using this device in their homes. The unit will NOT eliminate the need for vacuuming, but those who vacuum regularly will find that their air is significantly more breathable.

It comes with a built-in fan to circulate the air, ensuring that the purifier filters out as many particles as possible. The air purifier is designed to control odors and gas, helping to improve the smell of your home.

Operation: What makes this bad boy a great choice? Not only is it fully programmable with a timer, but the remote control makes it easy to turn on/off and select one of the three speed settings from anywhere in your house. The monitor will let you know when it's time to clean or switch the filter.

The Hyper HEPA filter will eliminate particles without generating ozone, so asthmatics have nothing to worry about. The device is built with German quality, meaning it will run for years to come.

Price: At $900, this is a high-priced air purifier, to say the least. However, for those who need clean air (especially during allergy season) and don't mind paying a bit more, the hospital-grade Hyper HEPA filter on this device is worth every penny.

  • Excellent for those with allergies and asthma

We've got plenty of ideas why this is an Amazon #1 Bestseller in HEPA Filter Air Purifiers. For a start, there's the appealing price tag to consider. 

  • Captures 99.97% of allergens with True HEPA filtration including dust mites, pet dander, plant pollens
  • Reduces odors from pets, cooking and smoking with activated carbon
  • UV-C light works with filter to kill airborne bacteria, viruses, and mold spores

Lackluster customer service and return policy. Additionally, some models release a bad odor.

Details

Performance: Built with a True HEPA filter, this air purifier eliminates 99.97% of allergens, dust, and particles from the air. It can filter particles as small as 0.3 microns, meaning it will eradicate pet dander, mold spores, pollen, and dust effectively.

The beauty of this bad boy is that it's an odor-killer as well, thanks to the charcoal filter. It will deal with unpleasant scents easily, leaving your house smelling fresh and clean.

The fact that it's not an ionizer means it will kill odors without infusing the air with asthma-triggering ozone. The CADR is 100+, and it can handle up to 155 cubic feet of air per minute.

It's built for small to medium-sized rooms (bedroom, office, small living room, etc.). Thanks to the UV-C light technology built into the purifier, it will kill off bacteria, germs, and viruses.

Operation: If you hate the hum of appliances running in the background, this is the air filter for you! It's whisper-quiet on the medium speed, and makes very little noise even on the highest speed setting. You can watch TV, read a book, talk, or sleep without being bothered by excessive noise.

It looks like a simple tower fan, and it will take up very little space in your rooms. The indicator light will blink when you need to replace the HEPA filter or UV-C light bulb, and the Energy Star rating ensures that this is a low-power consumption appliance.

Price: The $90 price tag on this bad boy is DEFINITELY a plus! You get a quiet air purifier that will leave your home smelling fresh, while also eliminating particles from your air. It's simple and has few frills, but it gets the job done! Well worth the investment.
