[This review was collected as part of a promotion.] This air filtration system is fantastic! We had a Shark system before and loved it but this one is even better! I love that we don't have to change filters! That makes all the difference! Never having to buy or change filters is a game changer for us! The other thing we love is that it has an automatic air quality sensor so that when your air quality gets worse, the fan speed automatically increases! You don't have to manually turn it up! We love this feature! We are enjoying this air purifier a lot already!

This air purifier has been wonderful. It runs very quietly in the background. The odor technology is great. We have 4 dogs in the house and when you walk in from outside, the house smells fresh and clean! I would highly recommend this product, especially for pet owners!

[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.] I absolutely love my Shark NeverChange Air Purifier MAX. It is very quiet. It is very sensitive. I can spray perfume or turn on a Scentsy burner in another room and it immediately can sense the smell in the air and goes to purifying. At that point it doesn't take very long before it cleans the air. Every time I walk into my home my home smells clean. I highly recommend this air purification system.

It hasn't been 6 months yet and my filter is at 2%. I clean the outer filters often.

This is by far the best air purifier I have ever used! Very impressed
