This works great. I have aquariums and with this running my PH has went up.

Very nice machine. Well built. Works great cleaning the air.

The filter almost immediately detects smoke so its pretty impressive

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.

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.

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

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.

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…

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

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

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.

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