Dr. Mercola ClearAir Personal Air Purifier

Air filtration for allergies, pollens etc. I change off daily with this one that has throw away batteries, and with the little lightweight ionizers that use the computer usb port for recharging. Either one works just great. Gotta be simple for me to use, and they are!! Love them. Have 5 altogether. jts

I bought through a really good company & it works ok battery lasts 40-45 hours & it was quite ( absolutely no noise to sart with but soon as the battery got replaced with same battery it came with it nows makes continues hissing noise) they say blow in top but makes difference? But apart from that its fine does what it says ive used mine for weeks now iam on battery number 3 £5 for 2x,s batteries 💯😎

Bought for a long plane ride. Worked wonderfully for about 10 hours of the flight. But then it wouldn't work any more. Returned home after a month out of the country and was told it was past third party seller's warranty date. Have learned not to buy from third party sellers on Amazon. They are totally reliable on things they sell but might as well know it is no better than just buying directly from unknown sources on the internet.
