Bought this and now for almost a year I haven't been able to get a new filter to replace the old one. Extremely frustrating when you can't get the replacement you need especially when you live in a wild fire prone area in summer . You must have replacement items available or it makes the product expensive and useless!

We talked our boss into letting us get an air purifier for our work space and we love it!!! The neverchange filter for five years was a good selling point to our boss. We love how easy it is to use and it seems to be really noticeably helping! It's cute too! A little big for our tiny workspace but we moved some things around and it was well worth it!!

Works really well and is quiet. My asthma has been a lot better. The wildfire smoke and general pollutants along with poking and such have made this a really tough summer. This air cleaner is really helping. I like that it has the odor pods and that they're easy to change. The machine is easy to care for too. I want to pick up a second one of these for my bedroom to see if I can sleep better and not have congested lungs and gooey eyes in the mornings.

Purchased this three weeks ago, have had it set up for a week now running, the prefilter screens on both sides are as clean as the day I turned it on the first time. My window AC unit filters more dust than this thing does. I would return it but I threw the box away, stupidly, because every Shark Vacuum I own has been amazing so I thought this should be as well. WRONG. My little dog is litter trained, when he goes to the bathroom the unit doesn't even kick on from auto to a higher speed to clean the air, 30 minutes later the air smells the same. I am going to give it a full month then if it doesn't work I will bite the bullett and buy another brand.

[This review was collected as part of a promotion.] We have a lot of air purifiers at home and this is by far the best one we have. The Hepa filter does need to be replaced which is the thing I don't like about other air purifiers. Filters are very expensive and it cost a lot of money to have it replaced. This one has 2 filters on the side that can be cleaned and put back after. I really like the digital indicator that tells the air quality that we have. It gives me a peace of mind to see that our air quality is good after running it for a while. If we see the air quality on orange, we run it on the fullest setting, then if it reaches 100%, we switch it to auto in order to maintain the air quality. We have a pet bunny and birds that shed sometimes and this air purifier helps so much in cleaning the air and getting rid of the pet hair. It also eliminates the unpleasant smell with the help of the odor eliminator. I really love this air purifier! No more costly filters!

I absolutely love my shark never change air purifier. I have the large one that does 1200 ft. I never realized how bad your air quality gets when cooking. I have this sitting in my living room and when I'm cooking it kicks on and the air quality is down in the 60's! Doesn't take long for it to get back up to 100%. When you walk by and see it says 100% it gives you a sense of calm knowing you're breathing the best air possible. I've decided to buy a small one for my bedroom. ❤️ 🦈

Purchased two units for 2100 sq.ft. house. They worked great for three months. Then they stopped working. Both units would only register 0 clean air. Cleaned the Hepa Filter per the instructions, cleaned all air screens including the sensor on the back. They worked....for two weeks and stopped again. Have cleaned the units every two weeks for three months. Today, neither unit will register. Cleaned them again for the second time in two days and still neither works. It is like they are talking/linked to each other...AI???? Shark replaced one unit but these units do not last 5 hears, they don't even last 1 year. Totally disappointed for the big money, not worth it.

[This review was collected as part of a promotion.] I am impressive with the features on this air purifier. The permanent filter will save me money. Thr on board controls feels new. I love that it tells me how clean my air is. I can have it run all thr time or use the timer. Includes a little separate filter for odors. It disperses a mild scent that is pleasant. It is pretty quite too! I love it! I find myself dusting less too since running this. highly recommended!

Can't live where I'm living without! Why? One tenant smokes which somehow I can smell. I have a feline which I'm allergic to. Shark cleans it all. Moreover, love the long lasting HEPA filter which is a huge factor to owning this unit. Any smell will show up on the filtration meter. Thank you Shark!

I bought this 2 weeks ago. The minute I plugged it in it said air was 100%. I left it alone and in the next 48 hours- still at 100%. I tried the perfume test , spraying about a foot away from the back of the unit, it went on with the fans at 2 for about 15 minutes then went back to 100%/eco. I even left the patio door open with "very high" pollen count outside, never went on. I know I have dust and I can see dog hair all over my tile floors. Don't think this was worth the price tag.
