Very quiet and effective
Really happy with this product. We have noticed a huge difference in the living room and we don't hear it at all

How did I live without it
Bought this a few weeks ago as I have been looking at air purifiers for a while. I am so happy with it, whisper quiet at night and my home feels fresh when I come home from work

Really happy with it
I bought this as I am looking after my daughter’s cat for a while while she is travelling even though I am allergic to animals. It is left in mid power continuously and seems to be doing a brilliant job. The house smells fresh, no cat fur smells and I have not had any allergic symptoms. It runs quiet and looks really nice. Definitely recommended.

Review of air purifier
It's been good especially in hayfever months unfortunately it's decided to stop working after 6 months so I will be bringing it back. I'm sure this us very unusual though

Great and easy to use
I bought this about a month ago for our bedroom as my husband always woke up coughing as he has asthma, and the bedroom was always stuffy. i only put it on at night till we get up in morning, and it really does help us both, having fresh air through the night.

Wish it had more features for the price but great
Super happy I bought this, I really do feel such a huge difference in the air quality in our bedroom as I have a really bad dust allergy. The dust still builds up, but definitely at a slowed rate than before. Only rating it lower because it doesnt have an automatic mode or air quality monitoring, but for what it is its great. The sleep mode is super quiet to the point where sometimes I have to double check its still on, and even the max mode isnt too bad that I cant sleep.

Helps clean the air and looks good too
My home is prone to dampness and can smell musty, blue pure 511 has helped remove this, it is also helping with my daughters asthma, whenever she feels ‘chesty’ we switch it on and she feels better.

Not great
Feels cheap, buttons are a bit funny. Not really convinced it is doing anything. Emits a smell after a while. I have an expensive phillips air purifier 3200i i think, which is better but I am still not that convinced that these things do anything for pm2.5 and vocs, and they both seem to emit a sawdust type smell, like chipboard

Air purifier
I bought this a few weeks ago to help clear the air when my dog has been in the living room. I can definitely feel the difference in my breathing.
