كواي ايرميجا 400

Very high quality, easy to use!

Gets rid of smells and air feels a lot cleaner. I would say it’s actually cleaning about 1000 sq ft of air (9 ft tall ceiling).

The unit has been incredibly helpful to keep down dust in an area where I've located two kitty litter boxes.

Got the prox in white/gray just before Thanksgiving since we would have a lot of people and cooking. In a great room 20x20x18’ tall ceiling. Open floor plan from there to kitchen and other living areas of about 1500 square feet. I put in auto on Thanksgiving morning and was reading about 2. As we cooked and people came over the unit was kicking into higher speeds since it showed 77. Then auto dropped speed as air cleared a hour later once cooking was done. Even at high it was not that loud. On low speed you really can not hear it which is good when you are watching TV or talking with others. I got this due to crowds during holidays to reduce viral risk and allergies. Dog, and us have allergies. Air smells better and feels fresher when breathing. I like the fact on wheels so easy to move around. Heavy at 50lbs but that is good so stable. Wheels can lock but have to tilt unit to access so an area they could improve is to have wheel locks more accessible. I do like prefilters are washable. Dual squirrel cage fan motors. Pulls air from both sides. Cost of replacement filters is high but if they last more than 12 months then may be ok. Has sleep and eco features as well. No fancy apps—surprising since made in South Korea. I like the smooth white sides since you could decorate with shelf paper or other vinyl sticker to blend in better—maybe a good etsy side hustle. I plan to leave on all the time so having a five year warranty should help if it fails. Ships assembled so just take filters out of bags, pull off shipping tape, unlock wheels, plug it in. Nice cord is removable in case you want to buy longer cord or need to replace.

We live in an extremely dusty area and have asthmatics in the house. This unit has done wonders to help eliminate dust, allergens and odors from the air. Every time I clean the removable filter I am extremely grossed out how much dirt and particles it collects. It’s easy to pop out, and when you do the unit shuts off. It is located in our kitchen living room area and even when we cook things like bacon or something gets Smokey you can see the unit light up and go into over drive! I recommend this unit to everyone who is looking for a hepa filter for a large space.
