    Works great. It's easy to operate. The filters seem pricey, but it's not bad for the amount of time they last.

    Very easy to use and clear indication of air quality. It seems to be a little less effective than the other one I have, hence 4 stars, but overall good value and works well.

    Easy setup and great air quality within minutes. Our dogs sometimes have a bit of a corn chip smell to them and this air purifier really helps knock the stench down. The air purifier is sleek and quiet we just put it on auto mode and forget it. One thing to note if you use a humidifier close to the air purifier it will detect the moisture in the air and cause the fan to run at a higher rate in auto mode.

    I live in an apartment complex where I can immediately calculate the quality of air just by smell, this air purifier is amazing at fighting against those wanted odors as soon as they appear. Super easy to use, can even double as a fan!

    great air purifier. my cats jump on it and like to turn it on and off so if you have a couple furry gremlins running around that'll happen. If your brother does 8 b0ngs a day this thing will have a heart attack each time.

    Happy with this Air Purifier

    I’ve had this for about a month and I’m very happy with this Purifier. I had a Levoit small room purifier and wanted to upgrade and you get what you pay for. (I got this on sale for about 229) Pros: Interface is very nice. Touch display on machine and comes with remote. I like the sounds it plays when changing settings. It also lets you dim or turn off the display for bedtime 4 speed settings with the lowest being very quiet. Unlike a lot of others, the air quality monitor in my machine is very responsive. When cooking things like bacon it will noticeably drop in quality. The build of it is nice looking so it can compliment a room with its looks. Cons Cost of filters. Although the lifespan of the filter seems very long, I think the range is around 70 bucks. Not really a con but this machine is very quiet on its lowest two settings. I can’t sleep with silence so I need some background noise and this machine has to be on level 3-4 for me.

    Very good air filter. Very quiet on the lowest setting, can’t hear it when I’m sitting a few feet from it. A bit more noisy on high speed but I’ll only use it if I’m stepping out. WiFi control could have been nice but not a deal breaker, it sits in a traffic area so I mostly control it from the u it itself, not even using the remote

    This purifier is amazing. I live with cats, and they release a lot of dander and hair so it often times causes my throat to become irritated. This purifier definitely helps and the noise is not irritating at all. I’ve noticed that when I spray febreeze or glade , the color turns red because of the components these sprays have. Cooking also turns the dial red. If you’re considering buying this, I say do it. It does make a huge difference.

    This is a purchase I would definitely make again. I’ve used it daily for 9 months and due to having bad allergies I can absolutely tell a difference. Went on vacation and came back 8 days later and immediately noticed a huge difference in the air quality having turned it off before we left. Luckily I caught it on sale for $100.00 off. Excellent purchase.

    This air purifier has 4 air intake fans maximizing allergen capture and it's slim unlike other purifiers. This one has a flat filter.
