    I got a 6 fan Shark for downstairs. Loved it so much that I got this 4 fan model for the second floor. It really helps with allergies. It can be set to be really quiet or turned up for white noise. I love the numbered air quality display!

    Another great deal of the day purchase. This is a great unit for larger areas. I love the PPM sensor that tells you exactly how 'dirty' your air is and the expected time to clean. The wife and dog who have allergies are both breathing and sleeping better.

    This is my first air purifier. We have two cats and live in a house built in the 60s. odor isn't too prevalent, but I wanted something to keep any pet or cooking ordors under control. It seems to work good, stays at 100% most of the time unless I am cooking with a lot of oil. Tends to cut the smell down in about an hour. I'm not 100% sure its the best out there, but I don't feel I have any odor issues. Probably doing its job.

    Excellent filter. It is very quiet! It speeds up and slows down its motors in response to the air quality in the room. Have not had to change the filter yet, but tells you how long until you have to. Filter will last a good while.

    When I first got it home and plugged it in I was nervous it wasn't working because it kept showing 100%; however, that evening when we cooked dinner the display updated to only 70% and the fans kicked right on! We can definitely tell the difference in the air quality in our home.

    So far, its been great. Its extremely effective for cleaning the air and the particle counter seems very sensitive to anything going on, even at substantial distance. Ive owned 4 or 5 air purifiers throughout the years and this one seems very well built by comparison.

    It works! We did some spray painting works in the bathroom near the living room and the air quality registry went down to 50's. This machine took almost an hour to clean the air, the paint odor went away, the air quality went up to 100's. Having this purifier gives me peace of mind.

    I live in the desert and I ended up buying 6 of these total after getting one. They made a huge difference in the amount of fine dust in the air and the air quality detector helped us identify problems in our home (we learned our heater was spitting out invisible dust)

    Amazing air purifier

    I've used several air cleaners/purifiers. This one is hands down the best. Easily takes care of a large room (18x20 in my case). Easy to use and set up. It's the quietest air purifier I've used. Cleans the air in a room FAST. I love the fact that it can read levels in the air, and you can see how fast it cleans the air. Used in a bathroom after cleaning it, normally the cleaning chemical smell would linger for hours. Moved the purifier in, had a reading of 48%. Within 10 minutes, the cleaning smell was gone, and the air was at 100%. My lady hasn't had any issues with allergies since we started using it. Again, this has outperformed previous air purifiers. We keep our home pretty clean, but it feels even cleaner now, and the air definitely has a fresher feel to it. While I haven't needed to change the filter yet, it's easy to access and will be a snap to replace. If you or a loved one have allergies or breathing issues, I HIGHLY recommend the Shark air purifier

    coming from a germ guardian purifier this is a HUGE step up. have it centered in a 3 bedroom home and it cleans the air perfectly. eliminated kitchen/food odor quick and helps spread cool air through the home with the AC’s on. excellent
