    Quite, sleek, and works great! We have a German Shepherd that likes to sleep inside the house during warm days and our guests always curious to know how we keep our house dog and dog food odor free. This device does the job.

    I bought this earlier in the year after a family member got COVID and love it for many reasons. It’s quiet enough to forget it’s there and it automatically increases power when the air needs purification. For example when cooking. Also, have noticed a decrease in dust allergens.

    Amazing purifier. Just started to use it in living room. My floor plan is open to kitchen and first time I cooked immediately the purifier started to sense and clean. Buy it! As for noise, I would say it's more of a white noise sound. Does not affect or annoy us. Clean air is worth it.

    This is my first air purifier purchase and I was not disappointed. You can definitely tell the difference in air quality. It’s so crisp and fresh. I put the fan on the highest setting at night and don’t wake up to a stuffy nose anymore. Highly recommend!!

    Quiet, very effective, reacts fast to cooking cleaning oders, lights off mode, auto mode is great to use for long filter life. I use the higher price filters for maximum air cleaning.

    We ordered two of these air purifiers. One for upstairs and one for downstairs. After hooking them up (super easy) and letting them run for a day, we could already tell a subtle difference. Then while cooking, the smell of burnt toast had that machine kicking into high gear! It immediately cleared the smell! Our upstairs one is located close to our dog's kennel and it works just as well. The brightness on the display can be reduced or turned off completely. Highly recommend!

    Excellent! I purchased this because of my lung issues, it dies exactly as described. Soon as it's turn on it calibrated my room starting at 100% then within 30sec it went to 39%. I set it to auto, immediately the fan turned to high and started cleaning the air. It reached 100% in about 1min, so I tested it. My place is 600sqt so standing far away it was tested. It took about 10sec before air started filtering A+. I also have bad allergies but mostly it was brought solely to help with my lungs. And it does. This product is worth the purchase. And all that needs to be done is buy it to know it. This unit clean up to 1000sqt, if your room is over 600sqt. Get the larger size. It makes a difference getting the right one for the best cleaning.

    Overall this a great product. My allergies are very sensitive at times and when they start acting up having the purifier on helps alleviate my sinuses and keep the air clean.

    Let’s me know the air quality at all times. It’s very sensitive to smoke and cooking odors. Easy to use and very quiet. Purchased for Covid safety air quality and the benefits have made the purchase worth it.

    Quiet and no worries. I also have other brands air purifiers. Now they all showing clean air most time of the day. It does take a few days for it to settle down. So if you find it showing low clean air percentage for first few days after turned on, it is doing its job. I put it in auto mode.

    This air purifier is a bit more complex than ones I got before, but the start-up instructions for this made it quick and simple. It's terrific that it has options for manual operation or auto-sensing so that the fans aren't on full rpm 100% of the time depending on air quality. It does manage to keep dust and pollen under control which help my allergies a lot! The replaceable filter does feel a bit much in price, but it's peace of mind. It's definitely better that I don't have to put up with frequent sneezing/stuffy nose from whatever is brought into the house during the summer. With winter around the corner, a.k.a. Dust and Cold Season, this will be better managed.

    Had to upgrade from my old Honeywell and this was the best thing I've done. I have a house with kid that have bad allergies and this unit does a great job. I couldn't believe it knew the air quality was bad on a high pollen day so I was able to close my windows so my girls wouldn't have a bad night. Very quiet fans is a plus also. The only complaint could be the filter placement every 6 months for 2 that i both is a little pricey.

    Just bought last week. I am back to back with the freeway, and that was the reason of the air purifier purchase. Once I plugged in the air purifier for the first time, it displayed 60%. After 30 minutes the purifier displayed 100% When cooking, the air quality drops to 45%. Once I turn off the stove burners, the air quality starts making it’s way to 100%, and the food odor start to go away. It takes 30 to 60 minutes to reach 100%, and of course it depends on your room size (sq.ft) I would recommend this: Shark - Air Purifier 4 with Anti-Allergen Multi-Filter to anyone with the same problem I have, or for any other purpose this purifier was made for.
