Customer Ratings & Reviews

The filter almost immediately detects smoke so its pretty impressive

The product photos don't accurately convey how tall and wide this unit is in person. It feels like a very noticeable part of the room's decor, and I could not find a good spot to put it in. I decided to return it.

It works wonderful. It has helped so much with my sons allergies

Works great. Happy with the purchase. Recommended for large rooms

Was a good item but it is too big in size and better features

so far so good. I just started using it. I like that it is very light to move from one room to another.

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.

This pretty much cleans air very quickly compared to the small one from Shark which I have

Seemed to work fine for about 3 months. After 3 months (and after the return period ended), it suddenly reads 0% air quality. There are no strange environmental issues that would cause that reading. I've tried the troubleshooting tips but nothing helps. I hope the warranty process is easy but expect that I will be charged shipping costs related to shipping it back to the manufacturer. I would not buy it again.

Have only had it for a few weeks so kind of hard to tell how well it works so far.

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.

Great for the price! Would reccomend to a friend to buy!

So far, works well. Cleans the air! I like that i can dem the lights on it.

It was great for a few months. Now it seems to reset to air quality of 0 every morning, then takes literally the whole day to get back to 100, then repeat everyday. Nothing in our home has changed…. For $300 it should last longer than a few months…

There are many things to like about this new air purifier from Shark, but there are also things that can be improved. Functionally, it works very well as you would expect from any air purifier. To start with the positives, it is very easy and intuitive to use. The touch buttons makes sense without needing a manual, and the display that shows your air quality can be very informative and easy to understand. There are two side mesh panels that can collect large particles and can be removed for washing. Chancing the main air filter is also simple as you will notice when removing the plastic covers during installation. Their scent features is also well placed and you smell it working immediately anytime the unit is running. The auto run feature is interesting to say the least. You would expect it to only run when the quality is bad, but it basically runs even when it says 100% quality. Not all the time, but at least 2-3 times a day which is more than my other auto detect air purifier in the same room. Personally, I do not mind since it does odor neutralizing but it would have been nice to be able to customize this setting. For improvements, there are many minor ones to list. For starters, the handles are unintuitive. There are two on the side that looks like they are for carrying, but in reality they are for removing the side mesh panels. What you have to do is carry it with the singular handle in the back, making it awkward and unbalanced when moving it around. So if you plan to move this quite a bit, maybe look elsewhere or deal with the inconvenience. Another complaint is the info display - it is either on or off. When you have the unit set to auto, the display stays on even if the unit is not running. There should be a setting to not display when not running, it just feels unnecessary to see 100% air quality for no reason. If you were looking for a whisper quiet fan, this may not be the right choice. At level 1, it is ok. But level 2 is not only quite a bit louder, the bearings on the fan rattle just a tiny bit. Finally, their claims on the longer lasting filters shouldn't really be a selling point. They are essentially saying the HEPA filter lasts longer because there are some additional outer layers to block larger particles before hitting the inner HEPA layer. We don't know what their "competitor" filters are being compared against. It also says the filter doesn't need changing, but then also says for 5 years? These are misleading advertising specifications and shouldn't be a factor when making your purchasing decision. Overall, aside from a few complaints, the unit itself does its job as a purifier decently. The automatic feature will give you a peace of mind, and the size of the unit gives it much more impact wherever it is used.

Plugged it in and it said my air was 95% clean already so not sure it it was actually working or not. After running a couple of hours it made a loud noise.

I just got this purifier today. It has been plugged in and running for about 6 continuous hours. It has not gotten above 70% in 6 hours. Our house is about a total of 1400 square feet so maybe that's why its only gotten to 70. Who knows. I guess I'll keep running it and see how it goes.

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

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

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.
