    I love how quiet it is. The highest setting is still decent noise level. It is instant in recognizing the air quality. Makes me go to sleep comfortably. Got this because I have bad asthma so it definitely has helped. Love the style the color etc. would recommend!

    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!

    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.

    Im sure it would've been great. However UPS is incompetent and couldn't deliver. (They usually leave my packages at someone else's house or hands them to someone without my permission. Id have loved to use this product but UPS had different plans. They lied and said it was delivered so they could say they delivered a day early. But then they messed up bc they told me it was delivered so i reported it missing. Bestbuy is awesome. Moral of the story UPS is trash. Maybe you'll get it. Maybe you won't. My gf has one that was actually delivered and she says its awesome so ill rate it from her experience since i don't have an experience due to UPS.

    So far we love it! I have noticed less particles floating around, less sneezing than before (we have dogs), and I just feel like its cleaner. We run it periodically on a timer. I run it at the same time my robo vacuum is doing it's thing. AND we run it when we cook so the smell clears out faster. I really dislike my home smelling like a restaurant or my laundry smelling like food.

    I had been looking for an air purifier for a long time. I live on a busy street and dust seems to accumulate overnight. Since I have been using this product, the air quality in my house has greatly improved. I highly recommend it. It is quiet, easy to set up and looks great in my home. I especially like the display showing when and how much the air needs to be cleaned.

    Amazing purifier. It's on the pricier side but we'll worth it. We have run this thing almost non stop for 9 months and it works great. It's very quiet for how much air flow it provides.

    We bought this to help with my husband’s allergies and asthma. We really like it and it keeps the air so clean. I am going to buy another for the bedroom area, as it’s quiet, and even at the highest setting, is quite tolerable. Highly recommend. (It’s nice that the clean air output acts as a small fan).

    We’ve had the air purifier for a couple of months now. Quiet machine and works well. We’re working on home renovation projects so I am happy to see the air purifier kick on when there is dust in the air. I love the auto feature and opportunity to turn the display off while you sleep. Highly recommend.

    Healthy again

    After moving into New place i started having allergy symptoms and heavy chest feeling. Bought 2 of these. The downstairs one was placed in living room. After an hour it was still in the red. The upstairs was yellow to blue. Thought one was not working right. Put them side by side. Both were in red in living room for 24 hrs. Something else had to be wrong. After researching and checking the house, turns out the AC/heat ducts were thick in dust. Immediately got ducts cleaned. The air purifiers were now 100%. I knew they work. While cooking it went to red but then right back up to blue after finished. BUT, then that night the one in my room went to red. I was confused. What was difference. I had turned on the humidifier. I turned it off and the purifier went up to 100% tested that theory by turning humidifier on again. Immediate drop into red%. I am now healthy again and I'm grateful that these air purifiers showed me what was going on in my house. I would recommend this shark air purifier.

    Who knows if it works properly, but looks nice! Quiet, but expensive to replace filters! (All large air filters). Long-term, initial expense does not stop with purchase of unit .. so set aside $100/year as cost of clean air.

    Honestly this has done the job. However we wish we got the bigger one since we use it in our main living area. This would be great for a large bonus room or bedroom. We still like it and has helped with when cooking but supposedly the bigger one helps with smells which would be better cause the people below us smoke weed and our apartment reeks of it. Overall its a great product but not for what we need it for.

    This air purifier works well. The controls are intuitive, it's relatively quiet, and the filter is easily replaced. Our first filter lasted about 8 months and we replaced it with one from a 3rd party - so far so good after 3 months.
