I did a lot of research before deciding on my Shark Air Purifier. Keeping in mind reviews questioning whether it works or not, I was wary when my Shark had air quality 100% to 99% consistently. I decided to give it a couple of weeks anyway. I had my doors and windows open earlier today and noticed the percentage on my Shark was in the 80s. I checked the air quality for the day, and we had a poor air advisory alert for the day. Closed my doors and windows within an hour the air quality returned to 99% to 100%. So Yes, I do believe my Shark Air Purifier works. Being asthmatic, I usually check air quality if I'm going to be outside. I didn't realize how much it affected my air quality inside until my Shark kicked in and I could see the difference.

I have had this air filter for 5 months. It does a great job and is so quiet! I do notice the air quality go down when I cook or even when I cook outside on the grill! Love that it adjusts itself based on need. Air quality is good. Is very easy to maintain!! Definitely recommend.

Got this April 2024, placed in our bedroom with old carpet and 2 long hair in house cats . It runs 24/7 reading between 94-100 depending on cats running around, it catches hair and much dust. When cooler weather outside I started running a humidifier and noticed the purifier staying on reading 50s & 60s so I moved shark to another room down the hall and it still runs 50s & 60s. During the day I started cutting off humidifier and shark goes back to 100. The shark cleans the air in several rooms of house but the moist air from humidifers messes with the shark senses.

I bought this a few weeks ago, and I was hopeful it would do everything the description said it would.  My wife and I built a new home, and it is so dusty.  She says she can dust one day, and the next day, everything is covered in dust again.  This was really bad in our bedroom because our furniture is dark.  After a thorough cleaning of the room, my wife tells me there isn't any dust, even after five days.  She is thrilled.  We do have the unit set up in the bedroom and have it at full speed during the day.  We are going to move it into the living room to see what happens then.  I will probably buy the smaller unit for that bedroom as no other room seems to get as dusty.

This air purifier has been wonderful. It runs very quietly in the background. The odor technology is great. We have 4 dogs in the house and when you walk in from outside, the house smells fresh and clean! I would highly recommend this product, especially for pet owners!

[This review was collected as part of a promotion.] Five stars! 😊This air purifier is amazing, it works for my entire house and the fact that I don't have to worry about changing the filter makes it even better. You can also monitor the air quality in your home with the purifier, it has 5 speed levels and neutralizes odors. It is ideal, I recommend it 100%, it is a good investment.

[This review was collected as part of a promotion.] We have terrible sinus issues in this home as well as pets, so sometimes the air quality indoors can get a little questionable, lol. Now since I've received this wonderful product I've really noticed a huge difference. The air doesn't seem as heavy and we don't have to dust as much!!! It's a real winner!

I did not think this was going to be as good as it turned out! The air quality in my house is GREAT! Just set it on AUTO and it cleans the air as needed. I even noticed better sleep and not waking up in the morning all stuffed up. This is a great unit, I purchased one for up stairs and down stairs. VERY IMPRESSED!

Shark is a fantastic company and have always made things right, now I had a six fan air purifier and the clean air sensor went bad so they sent me the never change max and I've had for few weeks and now the clean air sensor is not reflecting clean air like my other air purifier's. So I'm going to contact them tomorrow to see what they will do about this one.

[This review was collected as part of a promotion.] Loving my new air purifier, with its sleek design. It tucks away perfectly in my living room to be hard at work, without even knowing it's there. I love how easy the setup was and am so excited I won't have to continuously be changing the filter since this one lasts much long.
