This is big compared to my other shark purifier 500sq feet it works great shut down when air is clean automatically

Ever since we plugged it in and let it run for a few hours, we noticed big difference. Amount of dust decreased significantly. And I don't have to mop my laminate every day, but once a week.

This is a good filter. The display of air quality is very helpful. It made me aware of bad air quality in the bedroom at certain times. The fans are pretty powerful and cleans the odor in the room. We have an infant in the house and this helps me make sure he is breathing clean air. My only complaint is that there is no proper handle to carry it from one spot to another.

I am very pleased with this air purifier. I have noticed a huge difference when dusting furniture, my AC filters and overall air quality. Picture shows filter after one week.

Works great! Would recommend and definitely buy another when needed. It's pretty quiet. Doesn't take much space.

Best air filter I've ever owned!!! It doesn't have that "ozone" smell some others have, and I love the auto fan option where it increases the fan speed when air quality goes down. Plus having the pre filters really help prolong the HEPA filter inside. My allergies love me now after buying this lol!!!

Worth every penny! I live with a heavy smoker, I purchased two of the Shark air purifiers and the smoke smell is 90% gone. I can’t even tell when they’re smoking in the house anymore! Also helps with pet hair/dandruff. I’ve owned a lot of air purifiers, but none that compete with this.

I am very satisfied with this purchase. Cleans the air in my room and if I needed it to it would probably clean multiple rooms

We moved to a brand new build house. We seem to be replacing the HVAC filters every 2 weeks. This shark air purifier confirmed how bad the air is in this house and does a great job of keeping it at 100%. It starts at literally zero and takes a few hours to reach and maintain 100%. Also looking forward to not having to replace another air filter regularly. It is incredibly loud, so does not stay in the room while asleep. Overall great device that covers 1400 sqft maintaining good quality air throughout.

This is what we were looking for. No need to change filters and works effectively and efficiently!

Very happy with it. The living room does not smell like a dog any more. Job done.

I’ve tried a variety of air purifiers through the years, and some of them work pretty well while others, not so much. When the pandemic hit and wildfire smoke also became more common, having these in your home went from a novelty, to more of a necessity. That, and I live in a very high pollen area that can cause my sinuses to go crazy even indoors at certain times of the year. So the Shark Neverchange Max hits stores, and it’s a little different than most other purifiers. The Neverchange has a filter that Shark estimates can last up to 5 YEARS in-between changes when used moderately, and this particular model can handle up to 1400 square feet if placed in a more open area. It’s a pretty good looking machine – they come in silver (more white) or black – and is moderately sized but not a monster, at just under 23 inches tall by just over 13 inches wide. Setup is quick – you just remove any plastics from the filter, put in an odor control cartridge (included) if you want, and place it on a floor at least 3 inches from any walls or objects. Took me less than 10 minutes after unpacking it to getting it running. The filter has varied states that start off by a basic dust filter, clearing basic air debris (which you can wipe off when needed), passing through a pet filter layer, a carbon layer, and finally a “Nanoseal HEPA” layer that can capture particles in your air as small as 0.1 to 0.2 microns. Side note – the first basic filter can be pulled out in two parts from both sides of the machine to wipe off (they look like machine handles but lift the filter out instead – the carrying handle is on the back). Air is pulled in through the sides, and clean air is blown up through the top. A digital readout on the front lets you know how dirty or clean your air is in percentages, and if put in auto mode, will ramp up or down the fan to clean more or less depending on what it senses. It will also let you know when it’s time to eventually change a filter or clean the dust filter. Or, you can simply set it manually for varied stages from low to very high depending on your needs. It’s very quiet in lower settings and once you crank it up you can definitely hear it, but it’s more like an air conditioning noise rather than anything obnoxious. You can set it to run for a certain number of hours and then auto shut off, too. Odor control cartridges can be inserted into the top (mine came with one) but I wasn’t crazy about the scent so have decided not to use it in mine. The power cord is 6ft which is pretty good, but I always like to see max lengths for items like this for the best placement in a room. My one complaint: There are QR codes on the setup guide and machine that allegedly take you to their web page for that machine, but in reality it just takes you to Shark’s generic sales page and after digging a lot I still couldn’t find what I was looking for. I didn’t need more ino as again, setup is very easy, but the QR really should take you directly to the product model number’s page in my opinion. Since I haven’t had the Neverchange for that long, I can’t rate the validity of it lasting up to 5 years, but I can say that it does make a big difference in the air quality in a large room compared to others I’ve tried. I have an air quality monitor that goes off from time to time regarding dust or other things in the air, and since turning on the Shark Neverchange, those alerts have gone way down, so it’s working. I would say that while it's a little pricey compared to some, this is a worthy investment to improve the air quality in your home or apartment considering the levels of dirt, dust, dander, and germ cooties that is typically inside these days, and by how much square footage it will clean out compared to smaller units on the market (provided the filter does last at least 3-5 years - time will tell). Thumbs-up!

Amazing!!! Works great Definitely recommended it .....

This has basically helped me to sleep better. I can finally breathe fresh and cleaner air. I love it.

Best product on the market and i got it at a good price.

Works as advertised, had no issues since using it for one month now.

Should have came with a remote. Doesn't immediately take bad smells away but it lessens them for sure.

Im not sure how I've lived without this airfilter. I have extremely bad allergies and this has help tremendously.

Love it. It keeps our entire house smelling great and we have a lot less dust. Love it!!

Bought the smaller version to test it out. Loved ir so much and got the bigger one. We have two dogs and lots of allergies with the grandkids and my house smells wonderful and clean. Definitely worth the buck.
