I just purchased this air purifier and noticed that within hours it was working great my house is not that big but it is cleaning all of the rooms I recommend this product

I really like this unit. It really does its job by cleaning the air. Its very quiet and has a few modes that increases the fan speeds when it detects unclean air. My only bad thing I have to say is that my previous unit came with a remote control. This unit does not have it. It would be a nice addition for this unit.

We bought this over a month ago. At first it was staying at 100% with a blue ring. We have 2 dogs, 2 cats and 4 people living in the house so it was surprising that the air was "clean". One we cooked and did some vacuuming it kicked in and dropped to 50% and started cleaning the air. We love that it shows current air quality and that it has the Eco feature, we leave it on all the time, 24 hours a day.

[This review was collected as part of a promotion.] I cannot believe we went years without one of these - the results are INSTANT. We live in the midwest. Basically a RED ZONE for all things related to air quality, pollen, pollution, etc. We also have dog, birds, cats. During the mornings, we like to open our windows to let some fresh air in but we also get the pollen. For years, I've had to have an inhaler as it affected my lungs. We tried the Shark NeverChange Air Purifier and what a wonderful piece of modern technology. Out of the box, it was ready to plug in. You also get the odor neutralizer (we have a home gym and that room gets rather muggy and smelly). We love the look, design, functionality, and the SILENCE of this thing. Even when it's fully powered. There's no distractions or attention drawn. It's beautifully sitting there in the corner doing serious work. I love the digital reader that shows you what your air quality is. We noticed how low our score would get after making breakfast, cutting the grass, or even running the vacuum cleaner. Rather than that air simply circulating with your ceiling fans, this purifier is recycling the air and you can feel the magic. The first night we ran this and then walked downstairs, it felt like a brand new atmosphere we were in due to the amazing air quality and smell. I haven't used my inhaler as I have had no breathing issues after we received this. That 'home smell' every home has is no longer present as the odor neutralizer makes your home / air smell quite amazing. I no longer have to apologize to my guests as we walk past the gym room as it normally smells just like a gym bag but it smells pleasant! This is a MUST HAVE piece of technology for anyone. Homes need these and your quality of life will appreciate you for it. We cannot recommend this enough!

I haven't even been using this a month, but I see when it is working. I was mostly interested in it's ability to remove dust particles from the air. Time will tell but it appears to be doing a good job. It's also very quiet, contrary to what a friend told me about another brand that she owned. Shark products have always been good quality since I've used them the past 20 years.

I really enjoy this Shark NeverChange™ Air Purifier MAX. The white color matches with everything I have in that room. It runs quietly because I use the Auto mode. Beautiful product design. I do not use the Odor Neutralizer because I do not need to neutralize odors, none. Overall, I give it a 5☆

We purchased the Shark air purifier as a replacement for one that did not perform very well. The Shark actually performs at a level that the advertisement claimed! It adjusts the level of air circulation automatically, It is super quiet and easy to maintain. We have been very happy with this purchase and would not hesitate to recommend this product to friends.

This small unit does 1200 square feet with no trouble. We put it on Auto and it quietly, quickly, and efficiently. Amazing little machine that does big air cleaning. Since it is so new, we haven't had to change the filter. But hoping that the "Never Change" filter will hold for several years or more. That was one of the big reasons we selected this model.

[This review was collected as part of a promotion.] The Shark Never Change Air Purifier Max is a great addition to my bedroom. The air circulation in my room is great, and it smells really good with the odor neutralizer cartridge. You can purchase replacements. I LOVE that the motor is whisper silent. It won't affect my sleep. It reads the air quality levels in your room. I am so happy to have this. I am going to recommend it to a family member who has allergies. I have used it for a while before I did this review to give an accurate assessment of this system.

[This review was collected as part of a promotion.] I love this thing. The gauge on the front that shows what the quality of the air is at is amazing! It definitely works too because the moment we start cooking the number goes way down and the filter starts working on over time until it gets back to 100. Helps keep dust away, and I think it helps with our cat hair (but I'm not sure bc cat hair still turns up everywhere). Also love that I don't have to change the filter so I dont have to keep up with buying the filters. Worth the money!
