Works great. The air is much better in my apartment. Daughter was having allergy issues and those seemed to have improved!

Some times it rattles. Also weirdly if it is like 2 feet above your head it makes a ticking noise.

Again filters to expensive

Bought this to help with allergies. Quiet. Good value.

For a small unit it works great for a large room.

What a find. As a person that travels most of the year for work, this has been PERFECT!! I had a stay at an extended stay hotel that had severe odors all the time. I searched for a solution and found this. The design and look is really great and the ability to put drops of oil in is genius! The scent isnt overwhelming and the design makes it last for a long time. On high, the noise can be a bit louder than expected, but the noise is constant and actually relaxing while trying to sleep. The great part is that the fan speed can be adjusted while I am in my room for noise reduction and I can crank it up when I leave for the day. If you travel for work and spend time in hotels, or are looking for a smaller space, do not skip over. Hits the perfect spot of price, design and works great. My single suggestion is to make sure that you carefully order replacement filters as it is very easy to order the wrong ones like I did and get hit for the charge. My mistake, but read carefully.

So far so good

This is the second one I bought. The first one is very quiet. You would hardly know it is there. The second one works well but has a bit of a rattle sound. Not horrible, just very noticeable. I have not used either with essential oils

This purifier worked great for me, cleaned very well. Now there are no filters available so it cant be used

The purifier works great. The only reason it is not a five is because you can only use their filter replacements, and they are never in stock, which is extremely frustrating.
