AMEIFU Air Purifiers for Home Large Room up to 1640ft², Hepa Air Purifiers, H13 True HEPA Air Filter for Pets Hair, Dander, Smoke, Pollen, Smell, 3 Fan Speeds, 5 Timer, Sleep Mode 15DB Air Cleaner

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

Auto function is great, relatively quiet and effective. Can’t figure out how to reset the filter red light after changing, any help?

Does as intended. Purchased a 2nd one for basement.

This is the first purifier I’ve ever used and I was surprised by how easy it was for myself to detect the difference within the first hour of use. This is a definite buy and it is very economical compared to other brands. Additionally, it comes with an aromatherapeutic feature that sets it apart from other purifiers. I use this one for the bedroom but I went ahead and purchase the smaller one for the bathroom as well. Definitely buy it; your nose will be thankful!

I just say this helps a lot with my allergies and helps out with the pet dust around... however, it is extremely hard to find a replacement filter, and when I do find a replacement filter, it is pretty pricey. I have two of these in my home and so far the price I found on the filter is $39.99 so I need two of these so that’s like $80 already out the door out of my pocket. I wish the replacement filter wasn’t so expensive I wish the replacement filter wasn’t so expensive and easier to find.

It works well. Helps keep the house from smelling like dog and my oldest hasnt been sneezing as much

Maybe good for a living room or large bedroom. Put it down stairs and it works I. The room it’s in. I do feel that room has better air quality and I sneeze less.

Nice units. Very quiet during normal operation . . . extremely quiet on sleep mode, but dont really need to run it on sleep mode since it is generally very quiet when running on low.

I like that I can add scents

This purifier seems to work well. Within the first 2 days of using I have noticed the dust in my house has greatly diminished. When its running its quiet. You do hear a slight noise but nothing that is distracting or annoying. Bought it at a great sale price so that is also a plus. I have severe allergies and have noticed a difference since running this purifier. Overall I think it is well worth the price.
