Greentech Environmental pureAir Personal - Wearable Air Filter and Air Cleaner, Air Purifiers for Home, Office, and Car, Creates 3 Feet Clean-Air Zone, All Day Purification

I love these products! They keep me safe in confined indoor spaces with lots of people. I get to breath clean air and not get what’s being sneezed and coughed near me. The air smells so good around me! Highly recommend!

I of course don't know if the product is responsible but I did stay healthy on the trip without masking! [an accomplishment for me]. the one annoying feature--which they mention in their description--is that there is nothing to indicate the product is on other than a slight--very slight--ozone-ish smell. I wish they had some way of indicating whether it was on--a light or maybe a different switch for on and off.

I call this my electronic mask, I love it. But like others the cord did fail on me, so Amazon has several solutions that will work and you can get it in brown or black plus the length you need and it looks OEM.The other issue which is big for me because I do love this product is the charging port. It has failed. This needs to be fixed by GreenTech on this model or everyone will have to keep purchasing new replacements.The other option I like on this is the capability to turn the blue light off and on. Other models you cannot turn the blue light off without shutting down the whole unit then you have no protection. But you do get that continued protection with this unit which I call my “electronic mask”. Comes in handy if you don’t want questions when you board an airplane.

Great at eliminating odors and dirty air. If you are sensitive to colognes, perfume, cleaners, or smoke this device can help. Easily rechargeable and the battery lasts all day for me.Love my purifier

I gotta say I think I love this product. When I first bought it I did a smoke test. I put it in a jar full of smoke, with no air circulation and it cleared the smoke. Not a totally scientific test, but good enough for me. Since then I’ve told my siblings about it and they have also purchased them. For me it’s a good supplement to keep me and my family healthy. I don’t think it will prevent it, but I do suspect it’ll mitigate it. Plus for the price in comparison to the more expensive brands it’s a no brained for a purchase. I’ve actual bought 6 of these for family. I would advise everyone to buy one for a little bit of piece of mind.
