Signature U300

Works great, had this running sincewe got it. Cleans the air well no inonising smell like u get with some of them. Less dust in the air. Leave it running in auto is very quiet when on the low setting. Gets louder on the higher setting. But this only happends when the air quality is poor. Am a bit conserened regarding replacment filters. They are extreamly expensive ..

I bought this to replace a much cheaper Bionaire unit which will effective was too noisy to use in a bedroom. This is much quieter while seemingly as effective. Build quality is good and the air quality sensor is handy. My main gripe with it is that it defaults to auto mode which has one big problem - when it goes dark the unit shuts down completely. I can see the point, maybe, during the night, but even at this time of year it is a pain that it turns off at about 8pm and in winter it will never be on. I have to bypass this and put it on the lowest fan setting at night but then if the air quality drops it doesn't change speed to respond. I'd prefer the auto mode to maybe halve the normal auto operation at night rather than turn off completely but at least you can easily override it with the remote control.

Very good value Air Purifier. This is the best designed air purifier I have had in the last 15 years and have tried quite a few. The WINIX U300 is very quiet on the slowest speed but is as near silent when it is auto mode and dark. Full speed and it will clear your room very quickly. Only negative is the display lights are too bright so have taped them over with tape

I have bought my air purifier a few weeks ago. It works continuously and I am more than happy with it. Sleep mode it’s amazing and don’t hear it at all. It has more than halved the amount of cat hair in my bedroom and for that I am so so trilled. I hoover the filters weekly and you can’t believe the amount of dust and pet hair caught on the first filter. I highly recommend this product

Got it to help with the hay-fever my husband has and dust mites and hay-fever allergies for my daughter. Works well, brilliant at night as it is very quiet on a low setting. My husband claims that he wakes up less during the night and his nose is not blocked in the morning! Also I can judge the improvement by the quantity of the used tissues on the floor by the bedside. One or two now compare to a used box overnight!

Purchased this after reading a lot of reviews. It's does a reasonable job and the turbo function works well. However, the light sensor does not work so when you leave it running at night it gives off a very bright light which is annoying. The air sensor seems to work, with the fan speed increasing when the sensor determines that the air quality has reduced. However, I'm not sure how accurate an of these sensors are in picking up the damaging PM 2.5 particles that are most hazardous. The product is surprisingly light which only feeds the impression that the build quality isn't great (this seems to be supported by the faulty light sensor) Overall it works OK but there may be better filters out there for the money

It's awesome during summer days as it also cools the air, but it starts to make more noises after a month or so. Needs weekly maintenance as well to brush or vacuum the big filter.

Love this machine. very very quite on the low setting- I am a very light sleeper but have no issue sleeping with it on. Looks great. Powerfull fan on the high setting. Instructions include nothing about how to wash the filters- the filters come as one unit- not sure if I should start pulling this apart to wash and clean it- very strange that no instructions included on this.
