Terrific product. I am very impressed with it. On low setting it's fairly quiet and can't really be heard. On medium to high settings. You can clearly hear the fan in a quiet room. However, with a TV on or playing video games, or just in a loud living room where you have friends, family, kids or pets, you will never hear it running. In fact, even in the living room, I can't really hear it. With the water running in the kitchen. It's not very loud, but in a silent room you will hear it. Filters the air perfectly and makes it smell better as well. Definitely works as I just cleaned the filter out after only four months, and it was just Clogged with dust. This thing does filter the air very well. I also noticed that in my computer room there is significant reduction in dust on my desk. I used to have to wipe it every couple of days. Now I can go a month without wiping anything before there's a little bit of dust on the desk. worth

Great product! Been running couple months, on all the time except to clean or change filters. Not a single issue with purifier. Definitely reduces dust settling on things, furnace filter lasts longer, got to be healthier not to have extra dust in house.

Quiet on low cycle which is adequate speed for air flow
Reviewed in the United States on March 4, 2026 by MrBob
I bought two of the air purifiers for my large combination living dining room area. There is a lot I like about the units. On low, they are very quiet. They are a bit louder than a box fan when turned on high. They have helped my sinuses and greatly reduced the need for dusting. They have a UV C light that can be turned on to help sanitize the air. I usually only run the UV when there is a lot of pollution or someone is sick. They look nice. The replacement HEPA filters are less expensive than many other brands. Overall I am happy with the units. They do have a two issues that bug me. They blow the air out of the front of the unit at an angle. It makes it a bit trickier to aim the air flow, but it’s a minor issue. My other concern is the carbon pre-filter is pretty thin. If you notice in my picture, the filter isn’t uniformly dense and you can easily see my fingers through it. My bedroom air purifier has a filter that is far denser and is of a uniform density. This will lower the lifespan of the actual HEPA filter. I might try to find a generic pre-filters that are a thicker and better quality.

**1/17/20 Update: it’s been two years since I purchased these and I still standby behind this product, 100%! I just replaced filters and it’s incredible to see all of the dust that this unit is able to trap. Even while disposing of the filter and quickly washing my hands after, my eyes became very watery and itchy which I’m assuming was due to the trapped allergens in the filter. My need to use my inhaler are few and far between. Same house AND another dog. So now three dogs in a small house and still no uptick of allergies/asthma. I run one in my bedroom, by where I sleep, and one in the living room. I turn them off when I leave but run them pretty constant when I’m home. This product has immensely improved my quality of life. I have asthma, two dogs, and a cat in a 900 square ft house. No sweeping and vacuuming in the world could allow me to avoid the inevitable breathing issues I had crop up frequently because of the animal dander in the house. I love my furry family but my constant sinus flare ups were taking a toll on my health and so I desperately needed something that could help clean the air in the house and provide me with some sweet relief. I purchased two, one for the bedroom and one for the main room- there are perks to a small house- as I don't have a lot of space to cover. I am happy to say...drum roll please...they are FANTASTIC! Since operating them (over a month now) I have had no sinus flare ups. This is a record considering I, on average, would have one once a week that would last on average 2 days. I am so impressed! I can breathe so much better and have not had to use my asthma inhalers as much as a result. Know that I am NOT a medical professional and am by no means saying that these little magical towers of awesome are a "cure," "treatment," or "medicine" for those suffering from similar respiratory aliments. This was simply my experience and I am very grateful to be able to breathe again! I will update this review if my condition changes (for better or for worse) but if these units work for the longevity to the effect they do now, than I will be a grateful longtime customer to the brand. P.S. I love the white noise they produce. It helps me sleep at night.

Several years ago, I got 2 of these same purifiers. They worked very well and I had no trouble with them. After these many years when they were not working as well and I was in the market to replace them, I bought 2 of the exact same purifiers. So I am very satisfied with their function and performance!
