Customer Ratings & Reviews

I never had an air purifier. I was always skeptical as to how would I know it was working or doing anything. My mind has been changed. Upon setting it up it indicated a 65 percent clean air in my den. Mind you I have a Golden Retriever so I wasn't expecting fully clean air. In a few hours it read 100 percent clean air and it stayed there. The unit is on AUTO so the fans speed up when necessary to filter the air. I moved the unit one floor up to another room and it still read 100 percent. OK maybe it cleaned that air too. I cant really tell at this point. This all changed when I was finished cooking breakfast that included bacon and a little smoke. I happened to go to the room that has the unit running and noticed the unit, which is a floor away, registering much less than 100 percent and the fan running at almost full speed. It also detected particles in the air. In short time it was back to 100 percent. Now I’m more convinced there is something to this. The unit seems to be doing what it says it does. Included in the unit is a small puck that can be adjusted to release a clean aroma. The QR code on a sticker attached to the unit takes you to the manual and all the info you need for the unit. No manual was packed in the box. The manual references a remote but I did not find one in the box. The unit is super quiet, you forget its on. I like the fact that there is a 5 year life of the HEPA filter. I thought it would be like printers, the printer is cheap but the ink costs a fortune. Likewise with filters for air purifiers, but not this one. No need to constantly change it. That is a big plus for this unit. You know all the cost going in. So I am now a converted skeptic and realize its a good idea to have this unit running in my home. As of now all the windows are closed and central air running. In the fall the windows will be open and there should be more work for this unit, I’m sure it can handle it.

I was super excited when I got this item, and reviewed it! I own multiple air purifiers, and some works better than most. A lot of the ones I have does clean the air somewhat, but not like I was expecting it to. Most purifiers that I have, usually only clear the air for a small room and that's about it. That is why I was shocked to hear about this one, which purify 1400 ft, which is the size of a lot of people's houses nowadays. I was also extremely excited and curious to know how a filter for one of these purifiers do not have to be changed for five years! I own lots of purifiers over the years, and I've never had a purifier like this one. This purifier literally does clean air of 1400 ft.² and probably a little more, because when I went to my basement, parts of that the main living space smell clean also! I believe that this is not even the most expensive air purifier I have, but is by far the best one! I hope that the air filter really does not have to be changed for five years, because that by self will save a lot of money. The biggest surprise of this purifier with it being so small, is that I really breathe a lot better since I've been using it, and it's not even close compared to the other four! I also like the really nice scent that it has that I don't have with any of the others. The only problem is, that you may not want to run continuously like when you're asleep, because it kind of dries you out like it did me. I have yet to find out other thing in the next few weeks that I may love about it, but this is very cost-effective for everything it delivers!

I've been using the Shark NeverChange Air Purifier for about a week and a half. I'm very impressed with what I'm seeing so far. The design on the NeverChange Purifier looks futuristic and really cool but the features are simple and very easy to use. There is no app, and no remote comes with it, so you have to physically touch the machine to operate it. That works for me but may not work for those who may need a remote or app. The thing that sticks out to me is the up to 5 year life on the filter. This is a game changer since most air purifier filters usually last a year or so depending on how much you use them. Since using this device I have noticed the smells dissipating more quickly after cooking. We use it in an open common area between kitchen and living room and it seems to work very well. Both of my kids suffer from allergies and while right now they are mild because of the time of year, I'm hoping this device helps ease their symptoms a bit. As far as functionality, the machine is super easy to use. The front display shows the current air quality in your home or area. If you're further away from the machine it will show a round circle of blue if your air quality is good, yellow if its fair and red if the air quality is deemed bad. There are 5 fan speeds from high to low 1-4 and then there's auto mode which recognizes when your air quality goes down and it ramps up the fan. Auto mode works for me since there's no remote or app and while cooking something in the frying pan, it just starts ramping up. There's also a time for when you want the air purifier to turn off and a child lock. Also included is an odor neutralizer that releases a nice scent while the purifier is running. Perfect to get those bad smells out of your house more quickly. I really like this device and I think it works well. I'm most looking forward to not replacing the filter so often. I do wish it came with an app or remote at this price point but to just set it and forget it is also nice.

The Shark NeverChange Air Purifier Max is another quality product by the wonderful people who create Shark products for our homes. The purifier boasts a 5 Year filter life with timely maintenance of course. As you unbox the air purifier there are very clear directions on removing the plastic from the HEPA filter before you turn it on for the first time. To do this you simply turn the panel on the bottom of the purifier and remove the filter. Once you reinstall the filter you simply turn the panel to the locked position and place the air purifier on level ground. You then install the odor neutralizing pod on the top by turning it until you hear a click and then you adjust the intensity as desired. Once you turn the air purifier on you can place it on auto and allow it to sense the air quality in the room. It will adjust itself based on the air quality. The air quality displays as a percentage on the front display. The once issue I have with my current air purifier is the cost of the 2 filters that get clogged fairly quick. The Shark has 2 debris screens that prevent larger particles from being sucked into the HEPA filter. These screens can simply be vacuumed and wiped down on a monthly basis. You should also remove the HEPA filter and vacuum it to keep it clean. The air purifier has the ability to exchange the air in a 1400 square ft space in 1 hour. The air purifier is very quiet and the lights are dimmable so it's not distracting at night. Overall I am very satisfied by its performance in the first few weeks of using it and believe this will live up to the high quality of shark home products

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.

Dont buy this item. It doesnt filter at all. I jave had it for 61 days (yep, just outside the return window) and it doesnr filter 1 micron of dust! The suction on it is poor and the only dust on the filters are the test pieces i put directly into the vents.

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.

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.

Returned after 4 days. Fan started to rattle. Bought a Dyson

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.

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

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

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

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!!

Excellent! Works great and easy to use! Auto mode ensures the fan adjust according to the air quality!

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.

works great but still trying to figure out the code colors and what they meant. It is big and bulky but it covers about 1400 square feet in the house.
