[This review was collected as part of a promotion.] I really enjoy this air purifier. I had been looking for one, for awhile, and it just so happened that I was able to get into this Influenster! I really love how clean the air seems! I have 3 cats and it is very hard to feel like everything is clean, when you have cat fluff floating around. The system is pretty sensitive, but in a good way! I also have a humidifier in my room that I need to use, due to bad allergies. Anytime I have them both on at the same time, my Shark air purifier air quality percentage tanks! Of course this is on the nose when it comes to how a purifier works. The only caveat that I have with the air purifier is that when you go to adjust the filter on the bottom of the machine, you turn it to lock it in place, but if you put it on a surface and turn it at all, it will unlock you filter, so just be careful!

[This review was collected as part of a promotion.] This new Shark Never Change Air Purifier MAX is designed to do such a great job on cleaning the air in my home and keeping it smelling fresh. I mean it was easy to setup the high-performance HEPA filter that looks very durable and won't need to be replaced until 5 years. It was also easy to turn-on the power of the purifier and let it do its thing, and I loved that it comes with a wonderful odor neutralizer cartridge that was easy to insert onto the top of the air purifier. I am so satisfied and happy with my new Shark Never Change Air Purifier Max!

Excellent, but needs some or better directions.

Product works great. Quite. Would purchase again

Terry quiet on low. A little noisy on high. Overall does a great job.

This is our second Shark Air Purifier and I love it more than the old version!

Best air cleaner we’ve ever had. High quality.

Great air cleaner! Love it quiet and never buying filters again is a huge plus
