The unit never changes from 100% we have 2 large dogs

Haven't had quite long enough to notice big difference

Doesn't really change the odor in the air and a little noisey.

Was faulty display. Showed air quality hundred percent all the time an returned it

I purchased this almost a year ago and have never had it work 100% correctly. For months it has said that air quality is 0% regardless of following the troubleshooting methods of cleaning the back sensor and the mesh dust screens, even vacuuming the filter. Pretty disappointed in this product.

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.

Seems to work a few days, others I don’t notice a difference in vanishing the smells.

I have more dog here in my house than ever I returned this once already, and still having problems with them

The Shark - NeverChange Air Purifier MAX is a great little air purifier. Setting the unit up was pretty simple. The fact that I don't need to change a filter every few months is a huge bonus. The unit itself is very quiet and hasn't been a distraction for us when watching TV or surfing the web in the comfort of our bedroom. Our air quality where we live is actually pretty good, however, with the way wildfires have been this year I can feel a little bit of relief that this unit is able to help mitigate that. That being said, I think this unit is best for people that live in smaller houses/apartments near cities. Being out in the country, I don't feel like I'm seeing the full benefits of this unit. One thing that is really helpful is that this helps with my allergies quite a bit. There are many air purifiers on the market, I see this one as a great buy for people that want to sleep better that suffer from allergies. The cost of the unit, the square footage it covers make this a pretty good buy for anyone that wants to improve the quality of their air.

This is a true honest opinion of actual buyer. Don't believe other fake reviews. My daughter has allergies and this didn't do a good job at removing smells or pet dander at all. I've used for 4 days now. My old vollara air pro works way better. Guess I'll be getting another one

Have had it for less then 3 weeks and already only reads 0% and runs non stop . Did all the trouble shooting and still reads 0%. Will randomly go to 100% for a couple minutes them go right back to 0%. Not happy and already past the return window . Guess best but only does 3 weeks now

It’s too early to tell if this is helping or not, it sure has some weird run cycles.

I bought two Shark air purifiers to reduce dust in my house. I waited five months to review them because I wanted to give them a fair shot. Unfortunately, they haven't done much to lower the amount of dust in my home. I wish I could return them.

Noisy when the purifier runs. Would have been better if it is calmer operation

Didn't get the job done. Did nothing to improve air quality and relieve allergy symptoms.

Shark did a lot of things right and a few things wrong with its new Never Change Air Purifier Max. The biggest thing they did right was build the Max around a long-life HEPA filter that, despite the product's name, DOES have to be changed -- but only once every five years or so. That is a lot less often than most other air purifiers and should save you a bunch of money because the filters are usually very expensive. The big. round main filter, which captures the really small stuff in the air, is aided by two additional first-stage DebrisDefense filters that fit into intakes that stick out on each side of the barrel shaped appliance. One of the washable sheet type filters used here removes big debris like dust and pet hair while a second carbon filter sheet helps eliminate odors. All filters are easy to remove and replace (or clean in the case of the first stage filters) which makes maintenance a breeze. And fairly economical compared to other brands. Overall operation easy too, with a top-mounted backlit control panel (a much appreciated improvement) with simple touch controls. In most cases, they are not really needed though since the default AUTO mode keeps constant tabs on air quality and adjusts fan speeds to deal with real-time conditions. Most of the time, the Max runs in a whisper-quiet low mode but the internal fan can crank up to much noisier hurricane force when air quality declines -- which can happen when you are cooking certain foods or something else messes up the air quality. A color-coded LED circular display on the front changes colors to let you know when air quality is bad. Blue is good while yellow, orange and red denote high particulates. There is also a number display in the center of the circle display that denotes air quality, with 100 being perfect and anything less than that needing work. The color circle also flashes to remind you when it is time to clean the side filters. A built- in sensor, dubbed CleanSense IQ, does a remarkably good job of determining air quality and automatically adjusting fan speed to deal with those conditions. Even better it will power down into a barely running eco mode after five minutes of 100 percent air quality, saving electricity and improving filter life. The control panel gives you the ability to dim or turn off the display, as well as manually adjust fan speeds, run the Max on a timer ( another welcome addition from some earlier models) , or change what information appears in the display. Another big plus with the Max is that it claims to have enough power to clean the air in up to 1400 square feet of space. That's an entire house for some folks and a lot more capcity than you usually see in an air purifier of this size. As for the overall design, it looks something like a high-tech garbage can. Constucted of sturdy white plastic, it is fairly light so can easily be moved around as needed using a built in hand-hold cutout in the back. My only reservation is with a new feature that is supposed to improve odor control. This consists of a small round "odor neutralizer technology cartridge" that screws into the top of the Max. It promises to produce a "fresher smelling home." This probably appeals to those who like chemical air fresheners but I am not one of them. Even on the lowest setting, I found the smell a bit overpowering and distracting at times. And I was alarmed by the long list of scary warnings associated with handling the cartridge. The good new is you can just not install this thing and be happy with plain old clean air. The Max really doesn't care. And that is one less consumable you have to replace. Despite my misgivings on that front, I see the Shark Never Change Air Purifier Max as a strong contender in the category, thanks mostly to its chart-topping 5-year filter and impressive ability to clean the air in an entire house.

The Shark NeverChange Air Purifier MAX has been a great addition to my home. It could be a whole home purifier as it will work on up to 1400 sq ft. It came with 4 items: the Shark NeverChange Air Purifier MAX, the Debris Defense Washable Filter, the NeverChange HEPA filter, and the Odor Neutralizer Technology Cartridge. I tried to place mine as centrally as possible on my floorplan. It has a mostly white look with a black air vent grill and buttons, so it will fit in most places very unobtrusively. Setup took 2 minutes and was as simple as taking the wrapper off the HEPA filter, putting in the Odor Cartridge, taking off a sticker, and plugging the unit in. I powered it on and it immediately began to analyze the quality the air. The display on the front has numbers that show the clean air percentage, PM1 particles, PM2.5 particles, and PM10 particles, and it is circled by a ring that changes colors with the air quality: from blue (good), to yellow (Fair), to red (Poor). The top of the unit has a number of buttons including for power, adjusting fan speed, Auto mode, air info, brightness of the display, shut-off timer, dust filter life, and a child lock. For me, the biggest issues in air quality are dust, cooking smells, and cat litter. At first I just tried the air purification and it did a great job. One of my kids is particularly sensitive to dust and I could tell after the first day that the dust was not accumulating at the same rate at all. Cooking smells from the kitchen can often be quite heavy in all parts of the house with the right dish, even with the hood fan on, but it did a great job on garlic and strong seasoning smells. On top of purifying the air, the unit has an Odor Neutralizer that you can adjust to receive a light positive smell. The job it did on eliminating any lingering cat odors, on top of the dust reduction and cooking smell reduction, made it the top of the line in my book. I have used other air purifiers that require the main filter to be either interchanged or washed quite frequently, and if I forget to do that regularly I always feed weird about using it. But I don't have to worry about that with the Shark. The NeverChange HEPA filter is good for up to 5 years. There is some regular maintenance that will need to be done, just to be clear. There are dust filters that require a sweeping when the unit tells me, but they are easy to get to and take out, and they can be cleaned and reinstalled quickly. I mostly ran the unit on Auto Mode which uses the air quality to determine the fan speed. Once optimal quality is achieved in Auto Mode, it will automatically run in Eco mode to increase the life of the filters and the unit. The Shark NeverChange Air Purifier Max wouldn't be noticeable at all as quiet as it is except for the amazing job it does at making the air not only smell clean but smell better too. It has done a remarkable job of making the air purified in the amount of time that I have owned it, and I recommend it highly for any use in any room.

I wanted to love it. It looks like a little droid. But alas, there seems to be a design flaw. When using auto, it doesn’t seem there’s enough air draw to determine if the air is “contaminated.” I have another shark that works perfectly. I returned this and decided to get the Levoit Core 600s

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!
