Ive had my air purifier for about a month now and I love that you can bearly hear it running.

Good at circulating air but not efficient with food smells from cooking

This is my second one for my home! Love this, helps tackle the "pet smell"

Smelled like melting plastic

Unless you have spare money around you would like to get rid of skip this product. Always going to 0 percent and getting the red circle. Places do not seem to care about quality anymore. First and last Shark product I will ever buy. The filter would last longer than the machine will.

[This review was collected as part of a promotion.] Shark NeverChange™ Air Purifier MAX covers around 1400 square feet that provides multi-room air purification. I currently have it up in the balcony area at the top of my stairs and it is taking care of the 3 bedrooms upstairs as well as the hallway and probably part of downstairs. There are several features I like about this air purifier. It has a “Neverchange” HEPA filtration that won't need replacing for up to 5 years. So, while it may not last a full 5 years that is an advancement over systems that have filter replacements needed annually. The 4-layer filter system captures 99.98% of allergens and irritants, dust, hair, lint and especially helpful with pets and when it's seasonal allergy season. It has this nifty little Odor Neutralizer Odor Cartridge Assembly that pops into a designated slot on the top of the machine that you can select how strong you would like the scent or you can turn off the cartridge if you do not want any scent. It has these “Debris Defense” screens on either side of the filter system that just pull out like the lint screen in your dryer, and you just give it a quick clean and slide them back in. They're like an additional assistant to the filter system. They it has Clean Sense IQ which is the control system/display and this tells you what the current air quality and particulates and odor levels are. It actually senses the quality of the air and “cleans” the air. Say you are cooking onions, the system will recognize the smell, the display will change colors and the system will go into basically air cleaning mode to get the air quality back to 100%. Sometimes it's fun to watch the color change. This system has been great and has been doing what it supposed to do.

So far I'm impressed

[This review was collected as part of a promotion.] I really love this Shark air purifier! It's really futuristic looking, and does an amazing job of cleaning the air. It has a cool touchscreen to select from 4 different fan speed levels to clean. You can check how clean the filter is, adjust the brightness all from the touchscreen! The best part is the scent filter. Makes my house smell so clean and fresh. I love this!

I am so incredibly disappointed with this purchase. I spent a lot of money purchasing this item (air purifier Max) and two smaller ones for our home. We have three long hair doggies (border collie and Aussies) that leave a lot of hair and dander. It is a lot of work to keep the home clean and our allergies at bay. I was researching ways to keep the home cleaner and us healthier and everyone recommended air purifiers, so I went with a brand I trust. I also have two shark vacuums. There has been ZERO improvement in the quality of the air in our home. There has been no reduction in the amount of dust in the home. No reduction in the amount of pet hair in the home. I'm still having to do just as much manual cleaning now as I did before we purchased them. It always says 100% air quality unless we're cooking something particularly smelly then it does kick on for a bit. I purchased this at the end of June - so three months later and the filter says it's at 78% already. I know never change doesn't mean never - but I was hoping for more than a year out of it. I feel like this would indicate that there is SOMETHING being done, but I am not seeing it. I check the filters regularly and despite there being plenty of hair in the home (yes, even with vacuuming regularly) and there's just about none in the filter. I'm not sure what this purifier is even doing for us and I wish I could send them all back.
