    I bought one of these for my downstairs and I liked it so much I purchased a second one for the upstairs. I have two dogs and two cats so i wanted something for the pet odor. I want to add that these have been running several months and not just a day or two. I have noticed a huge difference in the air. My house smells fresh. I have noticed there’s less dust. I am so impressed I purchased one for my significant other’s home. I recommend to others.

    This works great! Got it for my wife who has allergies and placed it in the bedroom. She noticed a difference almost over night. We are only running it a night. Very quite. If has different speeds on it and you can dim the lights on it if the dial lights are too bright. It is good size, but that is what we needed. Very solid machine. I will buy again if we need another. Got it on sale, 50.00 off!

    Does a great job at removing odor from the air, like burnt popcorn, or over cooked food. Very quite

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

    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.

    Awesome unit! Quickly picks up cooking fumes or other air changes and begins to clean air. Will only exert cleaning when needed. Filters do last a long time and it shows you how much time is left on them. Loved so much bought a second unit.

    I love Shark air purifiers. They keep the air clean and comfortable. They really worked for me and my allergy symptoms are so much improved. They also remove odors and smells. I really think I even have more daily energy because of these air purifiers. Best air purifiers. Super easy set up too.

    So far we really like this air purifier it does almost a whole level of our house. Air has improved drastically but I would combine with a humidifier in case your house is dry

    I love how modern and sleek this looks- plus its slim, so doesn't take a lot of space- very nice display panel and easy to use and runs very quietly. Lets you know the air quality as its cleaning it- comes with a remote also- I ended up purchasing 2 of these- definitely recommend

    Ok, this is a great air filter. Our bedroom serves as a home office so we have a lot of dust build up as that is where we spend most of our time. After placing this filter in the room, we have noticed a significant improvement in air quality and practically no dust anymore. Highly recommend.
