I bought KVV purifier a few weeks ago, suppose I wanted to buy it at Costco, but they sold out, so I bought this .I have been using this purifier for several days. It is comfortable to use. I like it for many reasons.1. Simple operation, easy to set the wind speed and time.2. It offers up to 800 square feet of fresh air, suitable for my living room and bedroom.3. The filter is of moderate thickness and precise production. Can quickly eliminate odors and smoke.4. When I set the sleep mode, the noise is so low that it doesn't affect my sleep at night.5. The other thing That I like most is the lock function. After startup I don't have to worry about my kids playing with it all the time.6. It does improve the air quality and my asthma has been reduced. Thank you for your products.

We got this on one of the daily deals, and for the money we took the chance. I’ve only had it for a little over a week. Wish I would have gotten 2. Works very well, the numbers climb when cooking or I had the windows open and we had a fire going outside, it went into high mode! Dust is down by 90%, with dogs and a bird well worth the money

I bought this machine with a replacement filter, knowing that it covers up to 800 sq-ft. However, CADR rating is below 240 (it is 123CFM), so I was kind of skeptical how fast it can exchange fresh air. I have been using in the living room (around 500sqft), a bedroom (around 200sqft) for a couple of weeks. In the living room, the machine is too small for 500 sq-ft (with the high setting, it could take a several hours or more to reduce PM particles and VOCs), but in the bedroom, it works fine. I have PM 1,2.5 and 10 reader with VOC measure, and while the machine dose reduce all PM particles fairly quick, it does not reduce VOC so much. When I move the PM and VOC reader on top of the machine, it does reduce VOC quickly, but I suppose since the machine does not have enough blowing power (CADR is 123CFM), it does not reduce VOC efficiently. Nevertheless, a replacement filter is $30 for up to 6 months depending on how much usage, and the unit was less than $200, I cannot complain too much. I do not know how long the machine would last for continuous usage, overall, I am fine with the product and intend to keep it.

These are quite when operating. After using the first one for a few days we knew having another in other areas of the house would be nice. Even our friends have purchased these for their homes.

Works well. I purchased two. I operate my two KVVs at high speed(3). A little loud, but all air purifiers get a little loud at high speed. I am very satisfied!

Works great and good price, not to loud. Would recommend.

I had this for an early Christmas gift. Since I work in a school, I thought it might give me an extra level of protection. So far, so good! Very quiet and seems to be effective. I have it under my desk, so it filter the air nearest me. I liked it so much, I bought one for my husband’s classroom and am considering buying more for the home.

It's a big unit so keep that in mind when considering a purchase. I have my speed set on a2 all the time being I'm confined indoors during the winter months and everything is battened down. It's a loud machine on that speed, I can hear it from across the room and have to turn the volume up two to four clicks on the tv from what I usually listen to it at. If your a smoker it takes about 1 hour to filter the air from red 500 back down to 7 green at the speed I specified earlier. Wish it had a remote but what I came up with and it works for me. When I get home from work I turn it on, set the speed and I also set the timer for and hour after I go to sleep that night so it's not on all night long and I don't have to deal with it anymore. That was an issue at first as I'd forget to either turn it off or get up to set the timer right before I went to sleep. After I got this and set it up, right now, it's in the master bedroom and I went nuts washing all my cloths that were in my closet and dresser drawers etc so I'm hoping with this on it will keep the cigarette smoke smell outta my cloths. So far so good but it's only been a couple weeks. I'd like to rate the longevity of the filters as I don't think it will last 6 months as there are smokers here but I might be surprised. My bedroom isn't a huge master but not a average one either so if it takes an hour to clean the air in there when it's all closed up having a space heater blasting hot air outta it and who knows how clean that air is and a smoker in there I think that's fine with me. I'm thinking it's kinda working over time in that room. If they would sell a remote with it I'd like it SO much more. It's a fine machine for what I paid for it if I don't have to spend extra money on filters a year. If it comes on sale pick one up.
