Customer Ratings & Reviews

Stayed on 100% air quality straight out of the box. Even with bad food smells it wouldn’t turn on in auto mode. Returned right away. Don’t buy.

PROS: - Filter lasts up to 5 years - Great for large rooms/areas - Quiet (for its size) - Built-in air freshener - Large display shows air quality CONS: - Only comes in one color Between the forest fires and usual seasonal allergies, this year (2023) has been rough for my family members that have asthma. We usually have an air purifier in every room of the house (especially in the summer and winter), but it really becomes annoying keeping track of which filters need to be replaced at what interval. This is arguably my favorite thing about this Shark air purifier: I don't need to worry about replacing the filter any time soon! It's a large air purifier, but the trade off is that it can provide "coverage" for a large room/area. Shark rates this for up to 1400 sq ft, which is great for smaller homes/apartments. We have ours setup near the living room and dining room, and it's working great! We hardly notice it, mostly because it's so quiet for its size. Sure, the fan will start to get loud if there are a lot of particulates in the air (like when someone is cooking or one of the kids forgets to shut the door/window on a smokey day), but the majority of the time you can't really hear it during normal activities. While the filter doesn't need to be swapped out for up to 5 years, one thing will need to be replaced more regularly: the air freshener that you can place at the top of the purifier. This is 100% optional, but I really like it. You can buy replacement cartridges off Shark's website.

The NeverChange Air Purifier is larger than any purifier we've owned and I was skeptical because of that, but now knowing we won't have to change the main HEPA filter for 5 years is totally worth it. To accomplish that there are mesh dust filters on each side of the unit that easily slide in and out. They can simply be cleaned with a vacuum attachment or cloth. It hasn't been long enough for us to need to clean them yet, but watching the youtube video provided by Shark, it looks very simple. I would highly recommend scanning the QR code on the front of the unit to get to the various tutorials and instruction booklet. "How to Maintain your Shark NeverChange Air Purifier" is the link to the mesh filter maintenance video. So far our purifier has been running quietly on its own showing 100% on the air quality so we haven't needed to do much with it. We haven't had an event that's needed to ramp up the fan speed either, but manually testing the max does get quite loud, but I don't anticipate the unit ever having to run very long at that speed. So overall we are quite pleased and as I mentioned, the big draw to Shark and this unit is the savings from not needing air filters every 6 months, etc. We are very happy and will look at getting another unit for the rest of our home.

No indication of actual filtering. Suspected bad sensor. Returned to store for full credit.

Air purifier does not pull the dust out of the room.

We didn’t feel any difference With or without that thing, so we had to return it.

I bought a Shark Never Change Air Purifier 6/8/25. This is my initial review. I set-up the purifier in my living room per the instructions, and turned it on at 12:30 pm. It started at the "auto" setting which I did not change. Withing a few minutes the air quality indicator indicated that my air quality was on the high end of poor. The air quality gradually improved. By 4:00 pm the air quality indicated clean air (98). My condo is 2,300 sq. ft. I moved the air purifier to my bedroom, which is on the far side of my condo. When I turned it on the air quality indicated 88. Within 15 minutes it was indicating 98. This unit is rated for 1,400 sq ft. However, I firmly believe that the air in my bedroom was being cleaned while the purifier was operating in my living room. There is no way the air in my bedroom would have immediately been rated 88 otherwise. I like the odor neutralizer. I may try putting a drop or 2 essential oil in it. It remains to be seen, how long the filter lasts. I had it standing right next to my recliner. It is very quiet. The air is drawn through the purifier by what looks like an impeller. It is not a traditional bladed fan. I imagine this is why it is so quiet. When I selected this purifier, I considered that I may buy a 2nd smaller one for my bedroom. At this point I do not believe this will be necessary.

Garbage. Doesn’t work. A $100 Levolt works more than this machine

This review is for the Shark neverchange air purifier. I am a big fan of using air purifiers in my home. I run 3 in total. The one thing that sets this one apart from the other is the 5 year filter life. That’s a big deal for me. As one of my other air purifiers uses a filter that cost $180 and needs to be replaced every 6 months. So in just one year I can save the cost of this unit. It has a easy to use interface. With all the controls on the top panel. You have 5 different fan speed settings for the fan 1,2,3,4 and auto. You also have a dimmer button with high, low and off. I have this unit in our bedroom and we like it dark so I keep the display in dark mode most of the time. Oh and you also have a lock option so if you have kids like me they can’t play with it and turn it off everyday. One thing I have found is after you put the display in to dark mode you can not set the child lock. This is very frustrating to me. Cuz my kids do play with it everyday. It would also be nice is you could control this unit with an app. But if the filter can truly less 5 years I can over look these two draw backs.

Not as effective as expected. Probably would be a better product with ion ca

Didn't see any difference in air quality in my home

It is much bigger than you think. Even with the larger size it’s easy to move room to room for single room air purifying. It is easy to assemble and operate. The filter is inserted in the bottom so it’s easy to access and change. The purifier has two easy to access larger particle screen filters that trap larger particles like hair and dust keeping them off the internal filter. The same item from Sam's is 20 less but comes with a remote. No remote on this one, costs extra. Overall great purchase and not having to purchase filters is a plus.

This purifier is capable of cleansing an entire livable area, but we mainly use if for the kid's room. Unfortunately, buildings near us have dismissed their non-smoking rules, and opted to open up their policies for some of the newer residents. What that has led to is a wave of harsh smell emanating into the household. Being that we can't control this situation, we wanted to find ways to minimize its effect. This Shark does wonders for that cause. It has a smaller footprint than our 3-in-1 Max, so it fits perfectly under their desk, with enough space to have effect on the room. Setup was simple, and we were up in minutes. Filters can be costly, as one of our purifiers requires a filter change every 4-6 months. Having a filter that can last five years is sincerely welcomed by our pocketbooks. The one addition my wife has enjoyed is the air freshener cartridge that can be installed. Although the odor filter does great for eliminating smells, the freshener aids in keeping the room fresh. Even better, the air freshener cartridge can be adjusted to control scent flow. We keep our on the lowest setting and it permeates throughout several rooms of our home. My son is going into the 2's and he gets his hands on everything. There is a touch screen for usage, and he couldn't keep away. If you have this issue, there is a lock on the screen that has deterred him...for now. This is the only purifier I have that has this, and it has been a necessary addition going forward. In summation, this Shark keeps the room smelling clean and fresh with a noticeable difference in the allergic reactions our my kids. From smoke to poopy diapers, the auto sensors act accordingly to rebalance the room in short stretches of time. If you have any type of similar situation, I recommend the purchase.

I love air purifiers, I started using them a couple of years ago and I wish I had started sooner. I no longer get watery eyes at home and I no longer break out in hives from dust mites, etc. The downside to the air purifiers is changing expensive filters. I have 3 cats and I smoke legal substances in my home so I tend to go through filters fairly quickly. When I was offered this new Shark product, I jumped at the opportunity. 1,400 square feet and a 5 year filter? Sign me up!! This could not have been easier to set up. Simply remove the tape from various spots, plug it in and you’re ready to go. I have a 1,300 square foot condo so this is the perfect unit for me. I placed it in the middle of my home, set it to auto and let its do its thing. I unplugged the other air purifiers in the home and this did not disappoint. I get the same coverage as I did with 2 units with less bulk and less noise. It’s an attractive design that blends in with my white and grey decor. It can get pretty loud but only when I’m smoking or cooking on the gas stove. It cuts down on odors, dust, air particles and more. This is the only air purifier I’ll need for 5 years and I love it!!

My house smells so much cleaner. I live in a 1952 Farmhouse and always has an odor. I have not noticed it since I plugged this filter in. I love the auto feature so you can plug and forget.

This is my second one i have, absolutely love it! No more stuffy nose, my sleep has been improved! Definitely cleans up the atmosphere in my home! I definitely recommend to anyone!

Great product! This product cleans the air fast and is very quite.

It is so quiet and does a great job keeping the air in the house fresh!

Its really respsponsive to odors and cleans the air nicely

I got this air purifier to reduce my allergy symptoms of mild cough/chest congestion on our ground floor. I believe it has helped, and I just purchased a smaller Shark unit for our finished basement room.
