[This review was collected as part of a promotion.] I just received it but what I can say so far is that it is quiet. I have a baby so that is important. Also the odor neutralizer smells good, I will not be using it until my baby is older however. I am looking forward to seeing how it does compared to other purifiers I've used.

Purchased two hoping to see a difference in the air quality In our bedroom and house. Pros. *Whisper quiet most of the time on auto. *Easy to clean * Ships fast Cons. *Price *Not sure it's actually cleaning the air my cheap filter seems to catch more dust and pollen. *The smelly cartridge to make the air smell clean is out in days even on the lowest setting. This is a short term review will update after a season of use.

[This review was collected as part of a promotion.] I have multiple air purifiers in my house because we live in a fire prone area and each year brings wild fires. The ash and smoke in the air is so unhealthy. Plus, the high winds and strong spring rain season brought up a lot of pollen in the air. These external pollutants mixed with cooking smells is why I use air purifiers. Shark NeverChange Air Purifier is strong and provides us clean air to breathe. Easy set up, easy and understandable display and stats. Not too loud and the advantage and convenience of not having to replace filters for several years (just wash the filters provided until replacement is needed) is just wonderful. This is my NEW FAVORITE AIR PURIFIER. Plus, it's beautiful to look at. Shark products have always been of high standard and quality and this one does NOT disappoint.

[This review was collected as part of a promotion.] Most of the time people don't think about the air around us, if it is good or bad air. I didn't think about it and you wouldn't believe the bad air that is around all of us, in our homes, outside, everywhere. I couldn't believe how much bad air that was around me and my family until I received the Shark NeverChange Air Purifier Max from influenster for free to review. I thought that there might be 5% to 10% of bad air but after it read the air and showed me that there was 36% bad air in my house I couldn't believe it. Every since I seen that there was 36% bad air around me and my family that day, I haven't quit using the air purifier to clean the air out in my house. It has made my house smell better. There is a big difference in the smell of good air compared to bad air. It even helps you breathe better. You wouldn't think that air could have so much to do with the way that you breathe but it really does. I am planning to buy a couple more of the Shark NeverChange Air Purifier Max so that I can put them in some of the other rooms in my house. It is quit and you don't hear it at all unless it detects any bad air and then you can hear it while it cleans the air but it isn't even loud then.

[This review was collected as part of a promotion.] This thing has been such a game changer in my house. My mom is on oxygen so it's important that the air quality is clear in the house especially with also having two cats and this thing has let us know when any issues arise. It's super quiet like you have to go near it just to hear anything and feel the air coming out of it. It's lightweight and not bulky and just overall does the job. Even when cooking and it seems like the smoke gets too much from frying oil it will let you know immediately that the air quality has dropped in the house. I love this so much!

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.] I absolutely love this air purifier!! For starters i love that the filter lasts for up to 5 years!!!! Not only does that save me a ton of money but it also makes it so convenient that i don't have to worry about changing the filter!! Set up for this air purifier took less than 5 minutes and it was super easy! The display shows me the air quality percentage as well as the amount of particles in the air. The display shows colors as well as levels so it makes it to super easy to just look at the screen and know by the color what level the air is at. blue is good, yellow for fair and red for poor. It's amazing how quickly it purifies the air as well! Whenever I cook the air purifier drops down the yellow & red levels but within a few minutes it's back up to blue! Overall i absolutely love this air purifier and definitely recommend it to everyone! My breathing is so much better and i've noticed my indoor allergies have significantly decreased since using this!

[This review was collected as part of a promotion.] We've been looking for something to help the poor air circulation in our apartment, and are very happy with this product so far! My favorite feature is the long lasting filter (5 years vs ~6mo life). Another favorite feature is the air quality indicator! Overall, I'd definitely recommend this product over other air purifiers I've tried in the past!

[This review was collected as part of a promotion.] i absolutely love this Shark NeverChange™ Air Purifier MAX this is the best air purifier i have found i had a little one before this and this is a beast compared to my other one i definitely would recommend this over any other one it is a great price and it gets a lot of stuff out the air that doesn't look like it's there i love this!

[This review was collected as part of a promotion.] This product is very unique as it has air intake vents and two sides which pulls in air from all over the room. It also has a display giving the air quality. It has several speeds. We run it on the second from the lowest speed. At that speed, it is very quiet while keeping our air at 100% clean. The fragrance cup is a nice cup to add freshness to the air. This is preloaded for you.
