Air Purifier / No Ozone Emission/ DC-Powered Safe Indoor Air Quality Nano Oxidation Technology 1000 sq. Ft Coverage

Only been a week, but so far fantastic. The fan can be heard but not so loud that it's a problem. It's fairly small and very light for easy moving. Has no ozone smell and what's really great, is that I don't smell the smoke in the house. The wife smokes in the kitchen. To date this has been an outstanding unit. The square footage of area it covers is what made me want this. I did have the Winix 5300-2 Air Purifier with True HEPA, PlasmaWave and Odor Reducing Carbon Filter. This was also fantastic to start, but I started to have some issues. I believe that it was just this one unit, because the reviews on the WINIX are great. I returned it. Started to get another one and then I saw this. It's a little more expensive, but the area coverage is so much more and has no filters to worry about. This Air Purifier after one week is tops and worth every penny if it keeps running this well.

It was pleased to receive the unit in a few day! My kid and I have severe allergies and asthma, I have used serval brands of purifiers with HEPA filter, all of them works fine but I need to replace the expensive filter from time to time, two bedrooms, dining room and kitchen. My friend sent me this Cyairnova non-filter purifier as a gift in April and it works great in my 1000 sq ft dinning room. I buy more unit because it was the time to replace the filter for my other HEPA purifier. It works and I am not required to buy filter anymore. It has NO ozone, NO ion Great!

I have notice a significant change in the air and dust in my house with days

Got unit and thought it was great until after day 4 it stopped working. I don't feel I can trust ordering a new one of the same type as don't want to replace it after 4 days. So disappointed

This is a lot of money to pay for a device that does essentially nothing. I expected far more than they deliver. My home is approximately 2,000 square feet; these devices are advertised to cover 1,000 square feet each, but they do not even come close. There is not speed control and the light on the front panel is disturbing at night when trying to sleep. No instructions came with it, so I am not able to determine what kind of care they need. Totally disappointed.

This thing is so incredibly noisy! Would work well in the garage, or in a noisy bar, or at a rock concert, but very, very noisy and not at all suitable for my home.

I was pleased to receive the purifier in just a few days! I was rather taken aback by its size and wondered how it could clear out smoke in a 1,000 sq. ft apartment.. I put it n the living room, but after a few days the room did not smell fresh yet so I moved it to the dining room by the kitchen. I smoke in the kitchen only but don't want to put it in the kitchen because of space. I am going to try it out for a week or so. If I am still smelling smoke when I have returned and been out all day and step into the apartment and it still does not smell fresh, I am going to return it. I will give it a fair trial run, but I can not spend $250 for a purifier that doesn't do the job.I may have to upgrade to something more expensive or get smaller square footage ones to get air purifying in each of the front rooms.

Cleared the air quickly - some people just bathe in perfume and I am allergic to scents. It was important to have it clear quickly and efficiently.

works well
