The PuroAir was very easy to set up. Two parts of my home are being remodeled and I have tons of dust. It took PuroAir about 3 hours to go from Red, the worst air quality to Green, the best air quality in my bedroom. The range covered my bedroom, kitchen, and living room. I opened the bathroom door and PuroAir immediately changed to red. This is one of the rooms being remodeled. The sensor changed back to green after 15 minutes. It is also very quiet. Review: Satisfied with purchase- doing what was advertised. - The air purifiers are working great! They are almost silent at low speed and do not intrude on sleep. They are small enuf to fit in a corner without presenting a danger to someone, like me, who trips over their own feet. Do they work? When I moved into the condo there was mold. My nose ran, my eyes itched. and I had a constant stuffed up head.?I I’m allergic to mold. Do I cleaned up all visible mold and ordered the air purifiers. Three weeks later after running one in the bedroom and 1 in living room 24 c7 my symptoms are gone - only return if it’s been raining which for me is norm. So I say they work to clean the air and make breathing easier. I’ll continue to use them as a precaution and also to ward off anything else that’s floating around - like what the cat brings in on his furry coat. ## Features - CLEANER AIR IN MINUTES: PuroAir is proven to filter the pollutants lurking in your home’s air.

Please type "Puro Air" in the below link for proof that this unit does not emit any ozone per the California Air Resources Board certification the unit has received. "Air cleaners that are listed as "Electronic" may be capable of generating small amounts of ozone, but have been tested and found to produce an ozone emission concentration less than 0.050 parts per million. This category includes ionizers, electrostatic precipitators, PCOs, hydroxyl generators, devices with UV light components, and other electronic air cleaning technologies." https://ww2.arb.ca.gov/list-carb-certified-air-cleaning-devices **Q: Is there a filter included in the purchase** A: Yes, there is a yellow tag on top of unit that reminds you to remove plastic wrap from filter before use. **Q: How long do the filters generally last?** A: We have had our Purifier for about a month and the filter still appears pretty clean. We have 2 dogs and a cat, I will probably replace our filter around the 3-4 month point. In general I would think most filters would last 3-6 months depending on pets or location. A dry dusty area or musty area would make a difference in what kind of particles will go through your filter. I would suggest checking monthly like you do a home furnace filter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Puroair Air Purifier *by R***E on June 3, 2026* Purchased the PuroAir 400 Air Purifier on the 29th and received it today June 2nd.
