“Sleek and simple, this air purifier cleanses the air and banishes bad odors — meaning “you will breathe better, sleep better, and dust less,”

“For a purifier that cleans such a large space (over 1,000 square feet) it’s incredibly quiet, lightweight, and compact.”
“This is one of the simplest and most effective upgrades you can make to your living space”
PuroAir Purifiers are highly regarded, and deservedly so. They’re competitively priced, and they performed extremely well against particulate pollution in our tests.”

“any improvement in air quality counts as progress toward a healthier lifestyle.”

WHAT’S HIDING IN YOUR AIR?
“When we moved to Iowa a year ago, my allergies started giving me severe issues that went 6 months or longer. I bought these two air purifiers and within hours my eyes stopped itching and watering and my nose stopped running. I am happy to say I no longer have allergies.”
- Gloria D.
“I don’t know if I should be embarrassed my filter looks like this or relieved that it is doing its job! Making a better environment for my family!”
- Jill
“We have three Siberian Huskies and it’s blowing coat season and in other words shedding season! You can visibly see the difference in the air!! The air in our home is so much cleaner now that we have our PuroAir 400.”
- Gloria D.
I’ve tried so many different things to get the dog smell out of house and nothing worked, until I got this. I was skeptical on if it actually made a difference until I burnt something in the oven one day and within minutes of the smoke appearing it turned red and kicked on high.
- Kaylee I.
A great purchase and it was worth the cost. The Puroair is very quiet and blows cool air that has been filtered from the top of the unit. I can feel a noticeable difference in my home.
- Folami
I haven’t noticed as much dust flying around in the air since using and the room that I have it in has almost no dust build up on the ceiling fan. I used to have to dust it weekly because it got so bad so I’m pretty impressed. Very happy with this product and considering buying more for the bedrooms.
- Ashlie B.
I bought this because I have allergies and pets. I use a very dusty cat litter. When the cat uses the litter box, this thing cranks up to eat it up! It has an auto setting that senses bad particles in the air. I was shocked when I changed the filter after only 2 months of use.
- Lisa
My HVAC filter—-which I usually change every 1-2 months—-has been really clean after 2 months. Even my duct cleaning guy mentioned how clean my filter was. And my wood furniture would have a layer of dust on it within 48 hrs of dusting. No longer.
- Kim A.
Works great at cleaning our dining room air! Look at the new filter compared to the 3 month used one!
- Morgan

FAQ's
What is an air purifier and what does it do? +
Devices that filter airborne particles3 like pollen, mold and dust, and some gases from the indoor air are interchangeably called air cleaners, air scrubbers, and air purifiers. Air purifiers work by intaking polluted air, pulling it through a three-layer filtration system, and then pushing clean air back into your living space.
PuroAir air purifiers automatically filter out allergens4, dust, pollen, smoke and everything you don’t want to inhale. Simply place the air purifier in a central location, plug it in and begin to enjoy clean, healthy air!
How do I choose the right air purifier for my home? +
Choosing the best air purifier for your home is essential for getting the best results. PuroAir offers two different sizes to choose from:
- PuroAir 240 HEPA Air Purifier – Perfect for small to medium sized rooms and indoor spaces up to 1,000 sq ft1.
- PuroAir 400 HEPA Air Purifier – Designed for large homes and indoor areas up to 2,000 sq ft1.
Need more coverage? Shop our Whole Home Bundle and Whole Home Plus Bundle for as much as 4,000 sq ft1 of clean air coverage!
Do air purifiers work with the windows open? +
Air purifiers are still effective with open windows, although their efficiency may be decreased. The air purifier will keep filtering the room's air, but its effectiveness is reduced by outside pollution, like pollen or dust, entering through the open window.
How often do I need to replace the filter in my air purifier? +
While HEPA filters are stronger than most other air filters, experts recommend that they are replaced every 3–4 months to ensure efficiency and effectiveness. PuroAir air purifiers include an indicator that will inform the user when it’s time to replace the filter after 90 days.
Take the inconvenience out of maintenance schedules by enrolling in our Subscribe and Save program. Get up to 27% off replacement filters, delivered every 3 months, and a lifetime warranty on your purifier.
Are air purifiers effective with smoke? +
Yes, PuroAir air purifiers are effective at filtering smoke from indoor air. The filter in your PuroAir air purifier includes a HEPA (High-Efficiency Particulate Air) layer that is designed to filter up to 99.9% of particles as small as 0.1 microns3, which includes most smoke particles3.
PuroAir air purifiers are strong components against cigarette smoke, wildfire smoke, and wood fireplace smoke. The HEPA filter reduces fine particles3, and the activated carbon filter layer can help filter out the associated odors.
Learn more with this helpful article: How Air Purifiers Combat Cigarette Smoke.
Do air purifiers help with dust? +
Yes, PuroAir air purifiers are designed to filter out dust and other airborne pollutants with their powerful air flow and triple-layer HEPA filters. They work by drawing in air and passing it through the pre-filter screen that traps dust and other larger particles3. The filtered air is then released back into the room, resulting in cleaner air and less dust settling on surfaces.
Where should I place my air purifier? +
For the best air flow and filtration, we recommend placing your air purifier at least 8 inches from the wall and any obstructions. The PuroAir 240 and 400 air purifiers intake air from 360°, so make sure to have plenty of room around the entire air cleaning unit.
You can also elevate the air cleaner to boost efficiency. In rooms that you primarily sit, like a living room, the machine can be lower to the ground. But in rooms that you mostly stand, an elevated air purifier tends to be more effective.
How noisy are air purifiers? +
PuroAir Air Purifiers are known for their very quiet noise output compared to other brands' air purifiers. Some factors that impact the noise level of air purifiers are fan speed, filter material and thickness, and placement of the machine.
- 240 Air Purifier decibel rating: Low: 22 dBs, High: 48 dBs
- 400 Air Purifier decibel rating: Low: 35 dBs, High: 60 dBs
Do air purifiers help with allergies? +
Yes, PuroAir air purifiers are great for people with allergies. By filtering out common allergens4 like pollen, dust mites, mold spores, and pet dander, it provides cleaner air and may reduce allergy symptoms.
Learn how PuroAir Air Purifiers can help fight indoor allergies with this expert article: Understanding the Role of Air Purifiers in Managing Allergies.
Can air purifiers improve my sleep? +
A recent study by SleepScore Labs found that the PuroAir 240 was associated with improvements in deep sleep and fewer awakenings during the night among adults reporting allergies. The study also showed additional improvements in self-reported outcomes, such as increases in perceived sleep quality and feeling well-rested, as well as reductions in the perceived severity of allergy symptoms.2

Do air purifiers help with pet smells, pet hair and pet dander? +
Yes, PuroAir HEPA Air Purifiers are highly effective at filtering pet dander and other allergens4. The combination of the HEPA filter and activated carbon filter helps capture pet hair, dander, and odors from your home, making them ideal for pet owners.
