LEVOIT Air Purifiers for Home Large Room with Washable Filter, 3-Channel Air Quality Monitor, Smart WiFi and Filter for Pets, Allergies, Smoke, Dust, Pollen, Alexa Control, 1395 Ft², EverestAir

Really smooth and quiet operation with a well put together app which was very important to me other than actual performance and loudness of the unit. The app clearly displays the PM1, PM2.5, and PM10 currently in the air rather than the generic good, fair, poor. The unit also looks great in the room, and fits well with most decor. It is a bit large but that's just physics. It needs to be a certain size to achieve the performance it touts. A bit pricey at normal price but it comes on sale from time to time bringing the entry price way down. It remains to be seen how effective buying third party filters will be since their first party filters are quite expensive. But we shall see. All in all a great unit.

This is the best air purifier ever! I’ve had so many, and they’ve been fine, but this is the first one with a high enough CADR and a pelleted carbon filter as part of the regular filter. I need that combination in my master bedroom (aka “the cat prison”) to combat litter dust, pet smells and ammonia. This works amazingly well, and it is quiet. It’s currently running at its top fan speed (3), and the noise is not intrusive at all. I have a round tower air purifier from another manufacturer in a spare bedroom, which has a lower CADR and three speeds plus turbo. Third speed is really loud, and turbo sounds like a plane landing! My roommate is allergic, and she can already tell the difference. I had difficulty choosing between this one and the 600S, especially with the price difference, but ultimately chose the Everestair for its removable pre-filter, the pelleted rather than impregnated carbon filter, and much quieter operation. Totally impressed.

I’m a lifelong allergy sufferer and have bought many purifiers over the years. Levoit is better in every level. Cleans air better and faster and much quieter. I now have two different sizes, one for family room and one for master bedroom. Yes, filters are expensive. But worth it to me.

Very nice quality, and is a perfect size for the area I put it. Super quiet! Immediately picks up when there is poor quality air and starts clearing the air with an increase in the fan speed and then slows down when the air is clear again.

Love these spoilers. Very simple to setup and really like the app control with all the options. It’s a very sleek design and fits in well. I did buy three and it’s nice they don’t stand out too much
