VAVA Air Purifier for Home Large Room with UV Light Sanitizer, Eliminates Germs, with H13 True HEPA Filter, Remove 99.97% Dust Smoke Mold Pollen, Available for California

For people who think the UV-C "light" is missing so you have a defective unit, please note:The UV-C light is "hidden" so you don't harm yourself. (UV light is harmful to your eyes and skin if you are exposed to the bulb. So to protect you it sits under a gray plastic cover at the bottom of the machine.It is underneath the filter, as I said, under the elongated gray plastic cover at the bottom of the machine. DO NOT TRY TO SEE IT, there's nothing there except a long glass bulb. In any event, if you removed the cover to see it in operation, that won't happen because the machine stays "off" any time the plastic grill is removed.Additionally, I saw a one-star review because that buyer thought he was cheated out of the expected four filters. The fact is folks, this air purfier, like all the others on the market, comes with ONE filter. (Ask yourself, at $109 would any seller be able to include what he said is "4 carbon filters." I don't think so.Nowhere in the listing does the ad say you are getting 4 filters, carbon or otherwise. What you get is ONE filter that has three parts, plus the UV-C light filter functionality. So that technically is four filtration processes. That's where his mistake was. He looked at the filter graphic pic, saw the single filter divided into three parts and mistook that to mean there's four filters in the box. The ad pic shows the filter "sandwich" is broken down into three parts: the "pre filter," the "carbon filter," and the "HEPA filter." It also shows the UV-C filter. 3 filters + 1 UV-C filter = 4 filters.____________________I liked that this model VAVA has the option to use UV-C sterilization. That was critical for our house to offer some protection against COVID.Additionally, there are two of us, plus a cat and two dogs. And as bad luck would have it, we're all sensitive to pollen, etc.Fast forward five weeks, there's raging fires here in Northern California. The end result for us in the big city (San Francisco) every year we get LOTS OF HARMFUL SMOKE. How much smoke? Well, I ran one window AC unit today because we are suffering a heatwave. Other Bay Area cities are experiencing 105-degree heat. Here on Nob Hill it is getting into the mid-90s.After running the AC unit for about 8 hours today, the mesh filter that was clean on Monday (I checked it) now has a layer of brown tinted contaminants on it (smoke contaminants). Out-of-context: If you are reading these reviews you all are aware of how harmful smoke pollutants are, to our lungs and the rest of our respiratory system.So in summary: 1) We have three fur-bearing beasts; 2) The wife and I suffer from allergies; one of our rescued dogs is also sensitive to contaminated air; 3) There's COVID contaminated air that can enter the house via the dust and debris kicked up into the air by, for example, the trash guys 3X a week; 4) Then there's the fires that's making our town look and smell like Peking proper.I had done a LOT of research about these (what I call) "air sanitizers." I restricted my search for a UV-C system because I already have some decent air purifiers that don't have that option. This VAVA system got the highest marks all over the Net. Sure as a crab's butt is watertight, when I set up the three units I first bought, they performed perfectly. I had really clean air in my place. But then there are the fires.I won't repeat what others have said, suffice it to say, I turned on the three units about 7:00 PM, all at full blast (#3 fan speed). Within three hours our house is ODOR FREE!!! Nuff' said about how well these perform.P.S. Before turning on the units I noted that inside our house the stench of fire smoke permeated every room of the house. Angered, I used masking tape to seal us in. I placed the tape around all openings where air from the outside was leeching in.Within our now-sealed chambers, the stench was totally gone by 9:00 pm.I'm one happy camper. I was so impressed I just now bought two additional units for the father-in-law, who is 85 years old. He can't be suffering the double whammy of COVID and the fire smoke. Him using these UV-C air sanitizers will let us sleep a lot more comfortably knowing he's protected.That's the end of my story.

I have tested this unit, and it does what the description claims, including filtering PM2.5.In order to test the unit, I first closed off one of my bedrooms, including closing the door and both HVAC vents. In this case, a 15'x10' room (150 square feet). I placed the Air Purifier on my desk at one side of the room. I lit a cigarette and let it burn down in an ashtray on the floor in the middle of the room, and used a small fan to circulate the smoke evenly in the room. I then took measurements of both PM2.5 and PM10 near the middle of the room. My Air Quality meter was pegged at 999.9 for both measurements (see image) meaning the measurement for both were likely > 1000 ug/m3.I then turned off the small fan, started a stopwatch and turned on the Air Purifier at it's highest setting. I surfed the internet while keeping an eye on the Air Quality measurements. The AQ measurements didn't move for about ten minutes, both staying at 999.9. After about ten minutes, both measurements began to drop steadily. At 1 hour 12 minutes, PM2.5 had dropped to below 100 ug/m3, which is considered "moderate" air quality, PM10 had dropped as well (again, see image).Overall, I am happy with the performance and test result, and will be ordering a couple more for around the house.

Definitely recommend! As far as replacement filters, they're available (I bought one to have for when it's time to replace). I'll put the link at the end.I bought this air purifier and a couple other brands (because of room size) for our apartment to help with my allergies and asthma since they've been horrible lately. I have this in between our living room and dining room area (it's open and all one room basically) and it takes care of that area without a problem. I don't consider it to be loud, but we live in an apartment with paper thin walls and use white noise machines so the additional white noise is nice.It's been great. I didn't expect it work this well. Since using it, I'm not short of breath and always feeling like my lungs are tight, plus I'm not sneezing all of the time, and my eyes aren't watery and itchy so I'm able to wear my contacts again. I've been able to cut down on vacuuming from daily to once or twice a week. Same with dusting.One last thing. My husband and I stayed over at my parents for a couple days for Christmas, they have a cat andb I'm allergic to cats. We brought the air purifier with and put it in the bedroom we were in. I didn't have any problems with my allergies or asthma.Replacement filters are here: https://www.amazon.com/gp/aw/d/B07CTFMQ6K/Carbon pre-filters which help your filter last longer or if you're trying to help with the smell from fcigarette smoke or other smells, they're helpful for that, too – these fit perfectly): https://www.amazon.com/gp/aw/d/B07CWB724V/

I've been stuck in the house with odors, stuffy noses, and allergies. I was skeptical about this but it's helped so much. The air is more breathable and even with a turtle tank, this gets the air smelling clean with the UV light. Will update on more findings but for now we have a winner.

First of all, this seller’s customer service is stellar. Immediate response to my question and immediate follow through with my request. Purifier is well made, easy to unpack and use. Just remember to remove the plastic from the filter inside before turning it on. Super quiet on low and medium settings and not too much louder on high. I only use high for quick elimination of cooking smells and smoke from outside with all the fires around our area lately. The air is just sweeter using this. Highly recommend. Do not be hesitant to purchase from this seller. They provide excellent support. I used email to communicate and they responded within hours. Thank you for a great product and platinum level service.
