I would have given them a 5 stars but their information/ instruction booklet is useless. I live in an old house, plus I have recently inherited multiple pets. It took me a while to figure out how to get it to stay on a constant speed. There is very little information in the booklet. You can tell English was not their first language, which may only be a problem because I obviously need things plainly laid out for me. Like the auto mode vs the on mode. Why the fan speed varies with auto and why the unit will only run for 12 hours

I bought it as a second air purifier but it seems to shut itself off and doesnt continue to run. Its very frustrating to say the least. After reading the bad reviews, it makes me worry that Ive made a bad investment. Hopefully, it wont be garbage. Make sure you buy the warranty.

To preface- I have two 150lbs Saint Bernards. Realistically I would need to change this filter every 3 weeks, Not every 2 months. When opened it was full of hair. I didn’t notice too much hair that was really gone from my floors though. The house had almost no dander in the air though. It got the job done. I’m uncertain if it’s worth spending the money constantly changing the filter but the unit itself is well made and efficient.

This no louder than a fan, and I like the sound of a fan at night. I use it in the basement because smell tend to linger with no windows, it smells really fresh now. Also I noticed that it pulls a flame so I know its pulling air toward the unit. All in all it was a good buy.

Sleep mode is GREAT. Very low noise level - PERFECT for getting to sleep.

Just received it and its very nice. Delivery is great always next day. So easy to set up takes minutes fits great in my apartment I have cats, so its needed. What was most noticeable besides its design is how quiet it is. I only had it on for about 2 hours and I went out when I returned the cooking smell for earlier was gone. I think this will work out just fine.

I run a resin art studio and in the Michigan winters I have to be inside. I worry about the fumes, even though they claim Zero VOCs. There is still a chemical reaction so any added protection is well worth it. This uses a 3 stage Hepa filter and the modes are amazing. At night I set it to Sleep mode. It still runs but at a much quieter setting. During the day I always set it to Auto. It detect the PPM in the air and adjusts to suit the need. I know for a fact that this setting works. When I start mixing my resin, the machine instantly increases the speed, and stays on high until the detection tells it to slow back down. That is peace of mind. Im on my 2nd filter. It alerts you when it needs changing. After putting in the new filter, you hold down the timer button for a few seconds and the red lights go off. I could not be happier with this air purifier.

i bought this so i could have one in the living space and a different one in the main bedroom. the old one was so loud i couldnt hear conversation on the tv. the AMEIFU air purifier is so quiet, i forget it is on. I Have to walk up to it to feel te breeze. at the time i turned it on i was having an allergy attack. it definitely helps with cleaner air. its minimized my allergies so far and the first filter has lasted forever! (not really but at least 3 months. if you have it on the highest setting it is pretty loud, but if youre the kind of person who likes white noise it shouldnt bother you.

The gift has mitigated several issues for the couple we gave it to. They seem quite pleased. I specifically asked about the ease of use, sound level, and net result of the filtration. Got thumbs up in response. Wouldn’t hesitate to buy one or recommend one to others.

I absolutely love this air purifier. I plan to order two more. Very happy customer
