    I live in an apartment complex where I can immediately calculate the quality of air just by smell, this air purifier is amazing at fighting against those wanted odors as soon as they appear. Super easy to use, can even double as a fan!

    This filter is hands down one of the best purchases I’ve ever made. I had several lung issues and my lungs were very sensitive. Bought this and the air quality instantly improved. The filter lasts forever which is great because I never turn my off. Big enough to do the job, but small enough not to be in your way. I highly recommend this filter. You will not regret it.

    We needed something bigger for our dining room, living room, and kitchen area and this has been a big help. Mainly looking for this to help with allergens since one of our cats has started to struggle a bit in the spring. Super easy setup, relatively quiet operation, and helpful button/LCD dimmer for night time operation. Noticed an improvement for our cat pretty quickly, we aren't trying to chase her down and put allergy drops in her eyes to stop the irritation any more. We do run the machine 24/7 though and try to limit how often we're cycling fresh air through the house. Also, we are impacted positively as well! Helping with odors and things has been an added benefit. It's also nice to see on the machine the estimated run time to get air quality to better%s. We do run another purifier on the other side of the house near the bedrooms, but its range is much less. Currently, it is set up near the wall inbetween the dining and living room and the cats don't seem to be bothered by it at all. Will continue to monitor and update the review of needed.

    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.

    great air purifier. my cats jump on it and like to turn it on and off so if you have a couple furry gremlins running around that'll happen. If your brother does 8 b0ngs a day this thing will have a heart attack each time.

    This is such a great purifier. At first I was wondering if it was actually operational since it was stuck at 100% but I noticed the change when blow drying/hair spraying my hair or frying foods. I also have two for a space that is under 1000 but I did that since the doors are kept closed with central air. If you have pets, I think you'll notice a great difference with odor. Highly recommended.

    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

    Very sleek design, does not take up a lot of floor space. Easy to use and the remote is a nice feature. Cleared the air in our home (900 sf) in about 2 hours. Auto mode is a nice feature too. We have birds and whenever the fly off of the cage the unit kicks in to clean the dander out of the air! Excellent buy.

    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.

    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!

    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.

    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 air filter was able to filter the air in my basement which was very helpful. Now I am able to be in my basement without having to worry about the air quality.
