OApier HEPA Air Purifier, MIni Air Purifier with True HEPA Filter, Desktop USB Air Purifier Smoke Odor Eliminator for Home Office Car, Portable Air Cleaner, Remove Bacteria Mold Pollen Dust, 3317

This desktop air purifier is just what I needed for my study as I have allergy problems. House dust and pollen in particular, it now sits on my desk to help filter the dust created by my computer and printer which are in use all day long. This unit is very silent running and uses very little power 1-5W and being light and compact designed to be used in small rooms, in the car or even in hotel room if required. This air purifier looks good and is a pleasing design and I think value for money.

I bought this as had hoped it was as silent as it said it was.This is as noisy as a fan.. its cheap and flimsy and after 3 days it is back in its box. Not much different in the air either .. waste of money and plastic

An excellent Air purifier that runs quiet and efficient. It looks classy compared to other air purifiers A++

The media could not be loaded. I want to like it, it looks nice, it has mostly good reviews, but...This this is noisier than I hoped, there is a constant hum. I actually took it apart, oiled it, and put it back together and it's still too noisy. I've given it 2 stars as it does appear to be effective at catching dust, my study window gets direct sunlight all day, and the number of dust motes hanging in the air appears less, maybe, but it's too noisy to leave on 24/7. At least in my home office, the noise of the computer somewhat masks it, but it's still distinctly there and not pleasant.Video: You may need to turn up the volume. I start it off, and you can see a dim blue glow when it starts, there is a faint whirring. There is something not quite right still, when tilted to certain angles, the fan makes a nasty buzz as it touches the casing, luckily my desk is flat so this doesn't happen during normal operation! After about 30 seconds of running, the fan speeds up on it's own, and it's very noticeable and not at all what I would call "quiet" enough to be left on permanently.

Had this a few days and you can definitely see the improvement in the air. For the price it is a great buy

Is what it is for the money. I have had mine a few weeks now and it's still running away and catches alot of dust spores

Hard to say if it is having a impact because i cant seem to see the difference.

You can hear the wizzing engine sound and it has no on off button
