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

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

Haven't had quite long enough to notice big difference

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.

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

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

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.

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

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

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

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

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 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!

The Shark NeverChange Air Purifier Max is another quality product by the wonderful people who create Shark products for our homes. The purifier boasts a 5 Year filter life with timely maintenance of course. As you unbox the air purifier there are very clear directions on removing the plastic from the HEPA filter before you turn it on for the first time. To do this you simply turn the panel on the bottom of the purifier and remove the filter. Once you reinstall the filter you simply turn the panel to the locked position and place the air purifier on level ground. You then install the odor neutralizing pod on the top by turning it until you hear a click and then you adjust the intensity as desired. Once you turn the air purifier on you can place it on auto and allow it to sense the air quality in the room. It will adjust itself based on the air quality. The air quality displays as a percentage on the front display. The once issue I have with my current air purifier is the cost of the 2 filters that get clogged fairly quick. The Shark has 2 debris screens that prevent larger particles from being sucked into the HEPA filter. These screens can simply be vacuumed and wiped down on a monthly basis. You should also remove the HEPA filter and vacuum it to keep it clean. The air purifier has the ability to exchange the air in a 1400 square ft space in 1 hour. The air purifier is very quiet and the lights are dimmable so it's not distracting at night. Overall I am very satisfied by its performance in the first few weeks of using it and believe this will live up to the high quality of shark home products

Dont buy this item. It doesnt filter at all. I jave had it for 61 days (yep, just outside the return window) and it doesnr filter 1 micron of dust! The suction on it is poor and the only dust on the filters are the test pieces i put directly into the vents.

Excellent! Works great and easy to use! Auto mode ensures the fan adjust according to the air quality!

PROS: - Filter lasts up to 5 years - Great for large rooms/areas - Quiet (for its size) - Built-in air freshener - Large display shows air quality CONS: - Only comes in one color Between the forest fires and usual seasonal allergies, this year (2023) has been rough for my family members that have asthma. We usually have an air purifier in every room of the house (especially in the summer and winter), but it really becomes annoying keeping track of which filters need to be replaced at what interval. This is arguably my favorite thing about this Shark air purifier: I don't need to worry about replacing the filter any time soon! It's a large air purifier, but the trade off is that it can provide "coverage" for a large room/area. Shark rates this for up to 1400 sq ft, which is great for smaller homes/apartments. We have ours setup near the living room and dining room, and it's working great! We hardly notice it, mostly because it's so quiet for its size. Sure, the fan will start to get loud if there are a lot of particulates in the air (like when someone is cooking or one of the kids forgets to shut the door/window on a smokey day), but the majority of the time you can't really hear it during normal activities. While the filter doesn't need to be swapped out for up to 5 years, one thing will need to be replaced more regularly: the air freshener that you can place at the top of the purifier. This is 100% optional, but I really like it. You can buy replacement cartridges off Shark's website.

Stayed on 100% air quality straight out of the box. Even with bad food smells it wouldn’t turn on in auto mode. Returned right away. Don’t buy.
