LEVOITAir Purifiers for Home Large Room with 3-Channel Air Quality Monitor, Washable Pre-Filter, AHAM VERIFIDE, HEPA Sleep Mode for Pet, Allergy, Smoke, Dust, Alexa Control, 2655 Ft², EverestAir-P

I've been hesitant about buying an air purifier for years. I never totally bought the whole thing about purifying air because it felt like a marketing gimmick, but recently my cat started sneezing a lot and my vet recommended I get one.Well... I was wrong. This thing is awesome. It tells you when the air quality is bad (I love checking on it via the app). I keep it on auto but you can manually set it. I recently burned a bit of food and the air quality meter was red and the air purifier put itself on full blast to clear it up! Lovely. My litter box is in the big room and you'd never know! Doesn't smell like anything. Best of all, my cat stopped sneezing.I signed up for the filter subscription which costs $50 for a replacement filter (though I've seen a lot of people vacuuming their filter so it lasts longer - will definitely try that hah!). They app tracks your filter quality and then sends you a replacement when it's gross. I appreciate that as I do forget these things.All in all a 5 star buy! Works super well, hassle-free, whisper-quiet. The plastic is smooth so it's quick to give it a quick clean if needed. I like the bright white colour, suits my room decor and looks modern.

We purchased one of these on sale in the hope it would help moderate the severity of pollen season in upstate NY and the dander generated by two large labradors. It has a nice, clean look and small foot print, which we feel is important.The HEPA filter was shipped inside it in a bag that needs to be removed but doing so was incredibly quick and easy to do. Twist the top a quarter turn and place to one side. Lift out the filter, remove the bag, lower the filter back in using the two tabs provided on it for that purpose, lift the lid back on and quarter twist to close. It takes 2 mins. Then its' plug-in, turn on and choose ""Auto" or a fan speed using the touch sensitive panel on top. You can control it from your iphone if you're into that but it certainly isn't necessary.The first thing we noticed is how quiet it is. Effectively soundless in sleep mode and at fan speed 1. Barely noticeable at fan speed 2, unless you're right next to it, noticeable at fan speed 3 when you are in the same room as it but not obnoxious. Noticeably louder at fan speed 4 which should be considered a 'Turbo" mode. Then we noticed the impact of running it - vastly reduced swelling of the eyes and sinuses of those suffering from hay fever and a significant reduction in the doggy smell of our labradors. It works really well.We have taken advantage of the ability to control this by iPhone to set a schedule where it automatically runs in sleep mode (low, continuous fan) from 10pm to 5am. Then at fan speed 2 from 5am to 5:30am, ramping up to fan speed 3 from 5:30am to 8am before switching to auto from 8am to 10pm. Because of the relatively severe allergies suffered by a couple of our family members the P2.5 micron threshold is set to 2 ug per meter cubed and this filter has been able to attain that incredibly low level with that schedule within a few hours of all windows and doors to the outside being closed to the 1800 sq. ft area it services. At this point we have an oasis for our hay fever sufferers to return to each evening and it's made an incredible difference to their comfort. Do they still take Claritin or Allegra during pollen season? Yes, we've found it necessary to deal with the pollen at work and in the garden. Are they doing better than they were before we got this filter? Yes, the continuously swollen and itchy, weeping eyes are gone. The inflamed nasal passages are gone. Their sleep deprivation is gone. Their quality of life has improved dramatically. We had no idea how dramatic an impact adding a quality, appropriately sized HEPA filtration system would have. This unit is rated for something like 3000 sq. ft. We're using to control air quality in a 1800 sq.f.t open plan area and its doing a great job of that without having to run the fan at high speed for prolonged periods of time.We've had this for several weeks now and experienced 1st hand how well it can deal with really terrible air quality when the smoke from the fires in Quebec blew into NY. Opening the door to come into the house with the shopping during the worst of it briefly dropped the air quality from a PM2.5 of 001 to as high as a PM2.5 of 185 within 12 feet of the door. This was then quickly reduced to a PM2.5 of less than 20 in an hour and back to 001 in about 2 hours after the door was closed. The outside airs PM2.5 was apparently North of 300 at this time (sources accuweather and the news), the air was literally a hazy brown like smog and this filter was able to detect it, automatically adjust its fan speed to clear it and maintain perfect air quality in the house.Does it work? Absolutely, quietly and brilliantly.Would we buy this again? Yes, in fact we have so that we can control the air quality for one of our allergy sufferers in another area where they have to spend prolonged periods of time. That one's been in place for about 3 weeks and has done exactly what we hoped it would do - improve the quality of life at work in a 7000 sq.ft. open plan office area. Now this is well beyond the manufacturers claimed coverage for a unit and it looks like they're right based on who's apparently benefiting and who isn't but here's the important point. The benefits to the workforce have been so noticeable to management they're now considering upgrading the offices HVAC system to include HEPA filtration. I think that speaks volumes.

Very effective air purifier for our home (1,408 SQ ft, one story).We leave it on automatic 24x7, and occasionally boost it to max when cooking or just to give the home an extra air cleaning, and we can actually feel the air pressure change at max, as can our cats.Definitely send to be making a difference on eliminating the amount of dust we used to constantly deal with.Love that it's default mode is quiet enough to sleep with while running (completely unnoticed), yet does it's job extremely well.Price is reasonable, but replacement filters are expensive, when the app says the original filter needs replacement.Overall though, 10 out of 10 so far (three weeks after receiving and setting up).Can definitely see and feel the difference in dust and air quality in our 3 bedroom, 2 bath home, with four people and a clowder of cats.

Even though this air filtering/purification unit isn't HEPA, it still does a good job.Things I like about it:The unit is quiet. We leave it on automatic mode (which will ramp it up if it senses pollutants) and only go higher on manual setting if we're cooking.The unit does a good job - it helps to clear out cooking smells quicker than not having it on (our kitchen "exhaust" fan only recirculates smells around the condo, doesn't exhaust them outside). It's not a miracle fix for food odors -- it will take time to clear it out and they sell filters designed to further help with food odors which have a small amount of carbon in them, though probably not enough to do it very quickly but it does seem to help.The warranty -- I purchased a unit in spring of 2024 and just recently the LED display started to go out on it. I contacted support and after following their instructions and disabling the original unit by cutting the cord they shipped me a brand new one. They were very nice and responsive and great to deal with.Things I wish could be improved:The filters, to me, seem very expensive. It's the old model of giving away the shaver for free but charging for the razor blades in perpetuity. There are after-market filters available, but I don't know if they have the same quality as the originals.They apparently used to call this a HEPA filtering unit, but had to stop because it wasn't one (or it wasn't certified, it's not clear to me). Wish they could make a HEPA unit.
