    I bought this for my sister's townhouse & she loves so much that she wants to buy a second one. It's well & continues to work. I bought the Shark Air Purifier 6 Fan version more than a year ago & it continues to work well every day.

    Mine works great. I read some negative reviews about the sensor on this product but decided to take a chance on it anyway. Mine works fine and makes a noticeable in the air in my home. The sensor detects odors and /or fumes from my kitchen and stove/oven 35 feet away in another room such as a heating stove/oven element, cooking foods and pungent foods like a strong onion. If you doubt your sensor, just cook some andouille or a good gumbo (win, win!), or shake a duster over the unit. Mine has also detected the use of spray cleaners and other sprays. PROS: Very quiet. My purifier stays on high fan setting and is located 4 feet below my television, six ft below front high/ATMOS speakers and directly next to my front speakers and home theater components (for dust control). It is barely noticeable during regular television viewing and not at all during home theater/movie viewing. CONS: Could do a better job of removing dust from the air. The air purifier, without a doubt, reduces the amount of dust in my air but it can only clean the air that passes through it. Dust, being a heavier particulate, has a nasty tendency to settle onto things and out of the air before it has a chance to pass through the purifier. I would be willing to sacrifice some of the quiet and put up with a little more fan noise and a little more less dust.

    This is a wonderful device. It is very quiet when in normal mode, but is a little louder if it senses something in the air and automatically adjusts fan speed, but not too loud. Tells when filter should be changed. Very sensitive to changes in air quality and can automatically adjust fan as needed.

    We have been very happy with this purifier. It is quiet, and does an outstanding job of clearing the smoke from wildfires out of the air in our apartment. This one unit actually maintains our entire apartment. I love the auto feature, so will turn off when air is good quality and only turn on when quality drops below 80%. This has also greatly reduced the dust and pet dander in the house which has made visiting much easier for our friends with allergies. The only issue we have had, is that at this point in time you cannot find replacement filters. I am hoping that Shark will rectify this soon, I have actually reached out to them and am waiting for response. We have used Shark products for many years and have always been very happy with the quality and this did not dissapoint!

    Have had this Shark unit for almost a month. Says the filter will last 6-12 months, we will see about that. I have 3 dogs woth lots of fur and dandur and this seems to help with the allergies. Doesnt get rid of pet smells, but does filter the air. So far its doing exactly what I needed it for. Will update as time goes on.
