Best air purifier!

[This review was collected as part of a promotion.] My brand-new Shark NeverChange Air Purifier MAX is the greatest air purifier I've ever used. It provides a cleaner and fresher environment by removing allergies and contaminants from the air. Since we installed the air purifier, my husband's allergies have significantly improved. We have two dogs as well, and I've observed that the dust in the home has decreased and it does not smell like dogs anymore. After cooking or baking the air purifier's little turbo went on instantly and cleansed the air. It goes without saying that the Auto Setting was quite useful and effective during the day. With simple controls and a washable outer filter, the device is simple to operate and maintain. Particularly for anyone with allergies or respiratory problems, an air purifier is a great addition to your home. Overall, the air purifier is a good purchase for anybody trying to enhance the quality of their indoor air. I would highly recommend this air purifier and are planning to buy one or my parents!

No more costly filters! My favorite air purifier!

[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've never had cleaner air!

[This review was collected as part of a promotion.] Just the fact that this filter doesn't need replacing for five years, is an absolute win! Both the unit and filter are large in size but so is its range of fourteen hundred square feet. This air purifier couldn't have come at a better time as our air quality levels in Michigan have literally been in hazardous range on and off all summer. It also helps keep all the dog hair out of the air, and off of the furniture with its suction and two pull out screens to keep it away from the filter! I am a huge fan of the lock feature, making sure once I have it set, my little one doesn't change anything! I can smell the difference in my home, it has the same odor neutralizer in it that my Shark vacuum does, and I love it in both products. Nothing makes a mom feel better than her little one going to sleep soundly, breathing in the freshest air possible!

Shark never change filter air purifer

[This review was collected as part of a promotion.] So far I'm loving this air filter. what I love most is you don't have to change the filter. there are 2 sections on each side that you slide up and remove so you can rinse the dust off . It's really not that loud on the first 2 settings but on 4 you can hear it. I mean its not so loud that it would disturb you. It was easy to assemble you do have to take the bottom off and take the plastic off the filter before you turn it on.. it has a little odor neutralizer thats smells really nice and clean it has settings to allow you to choose your level of fragrance. The top part shows you the power button the timer and you can adjust the light on the front and the top in case you like it dark the timer goes up to 12 hours . there is a led light on the front that shows how clean the air is .and it tell s you how clean the side filters is . Having pets can sometimes be challenging as far as allergies. What I love most is you don't have to change the filter and it saves you money in the long run. I will say after a few days I felt like my sinuses were dry so I only run it while cleaning house and if we're expecting company . This is definitely worth every penny I highly recommend it

Don't buy this one.

I have the large size in my living room. It picks up all the cooking smells and cleans them away. No issues. I have the smaller one in the room with my litter boxes. It does absolutely nothing. Says the air is 100% all the time. The room is no bigger than a closet. I had it in my master bedroom first and it did nothing for the dust. Smaller one needs work.
Response from sharkninja.comBy SharkNinja, October 6, 2025
Hi there, \nThank you for your honest feedback and for using both sizes of our NeverChange™ air purifiers. We're glad to hear the larger unit is working well in your living room and helping with cooking odors — that’s exactly what it’s designed to do!\nWe’re sorry to hear the smaller unit isn’t meeting expectations in your litter box room or master bedroom. If the air quality reading consistently shows 100%, it may be due to the sensor not detecting particles at its current placement or limited airflow in the space. We understand that doesn’t reflect your experience, and we’d love to help troubleshoot.\nPlease reach out to our Customer Care team at 1-855-427-5127 so we can look into this further and ensure your purifier is working as intended. We truly appreciate your feedback — it helps us improve.\nKindly,\nShark Clean US

Pretty nice but so big

[This review was collected as part of a promotion.] I’ve never owned an air purifier before but I was not expecting this to be so big. This was relatively easy to set up, but it definitely takes up a bit of space. I can’t distinctively say whether using this has made an extremely noticeable difference in air quality, but I do feel like there is an improvement.

[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!

Works very well!!

[This review was collected as part of a promotion.] I’ve had air purifiers in the past but this has been the best one I’ve ever used. I keep it between our kitchen and living room. Anytime I have an odor in the kitchen, it works so well at making the odor gone fast!! I love that it shows the percentage of how clean your air is. I keep it on auto because that is more energy efficient. The max is very loud so you wouldn’t want it on that all the time. It is large but that isn’t an issue with me. I love that you don’t have to constantly change the filters. I highly recommend this air purifier!!
