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

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.

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.

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

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.

This product is great. It kicks on automatically when I'm cooking and could tell the air is different.

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.

Unboxing and Setup The unboxing and setup of the Shark NeverChange air purifier was simple. The included Quick Start Guide has clear instructions and illustrations for setting up the unit for use. Removing the packaging around the unit, tape on the fan vents, and the internal filter was simple. I unpacked the included order neutralizer and followed the instructions for inserting it into the top. I placed the unit on one of our side tables in our living room about a foot from the primary window, plugged it in, and pressed the power button. The unit has easy-to-understand controls and displays on the top and an air quality display on the front. The unit immediately tested the air quality and automatically adjusted the fan speed. The initial reading of our air quality was 85%, and within an hour, it was up to 99%. Usage Usually, I don't need to use the air purifier since the quality in my home is 98-100%. However, in the past few years, we have had smoke from summer fires, and I expect we are due for another season of smoke. So far, the only extensive test has been when we are cooking. The air quality can drop to around 85%, and the unit does an excellent job bringing it back to 99% within an hour. I always leave the unit running since we have two cats and a large living room. The air is noticeably cleaner and smells fresher. I'm impressed with how quiet the unit is in automatic mode. It is noisier but tolerable if I force the fan up to full speed. Due to the shape and look of the air purifier, my wife says it should come with robotic arms and move around the house on its own. Features • Touchscreen controls and a clear display on the top of the unit. • Touch controls for air cleaning mode, display light intensity, particulates info, fan settings, time till the air is clean, and lock to prevent accidental control selection. • Air quality display on the front of the unit. • It can clean the air for multiple rooms up to 1400 square feet. • Airflow is through an anti-allergen NanoSeal HEPA filter. • Two DebrisDefense easy-to-clean filter screens for trapping hair, dust, and lint, protecting the HEPA filter for a longer five-year life before replacing it. When the ring on the front display pulses, it is time to clean the side filter screens, which easily lift up and out on each side. • 99.98% of dander, dust, odors, smoke, pollen, allergens, irritants, and pet hair are filtered out, thanks to the medium particle, activated carbon, and NanoSeal HEPA filter layers. Per IEST-RP-CC007.3 99.98% @.1-.2 microns. • Auto purify mode (Clean Sense IQ) will monitor the air quality and adjust the airflow accordingly. • Includes an Odor Neutralizer cartridge with three settings to guard against odors and release a fresh scent. • The replaceable air filter is suitable for up to five years with regular cleaning of the DebrisDefense filter screens. • The display can show air quality and the amount of particulate matter in the air in increments of particulates per million at 1.0 microns, 2.5 microns, and 10 microns. • In Auto Mode, if 100% clean air is achieved for five minutes, the unit will enter Eco Mode to optimize the HEPA filter life. Summary We are delighted with our Shark NeverChange Air Purifier. Undoubtedly, we will be healthier and safer during fire and pollen seasons, and there will be a lot less cat dander floating through our air.

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!

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

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.

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

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

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!!
