[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!

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.

[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.] We have terrible sinus issues in this home as well as pets, so sometimes the air quality indoors can get a little questionable, lol. Now since I've received this wonderful product I've really noticed a huge difference. The air doesn't seem as heavy and we don't have to dust as much!!! It's a real winner!

Seems to work well. Moved into a very dusty old house and felt like the air quality wasn't great. I love that it gives easy to understand air quality rating. We started at like 55 percent. After it gets to 100 percent it shuts off. It's a couple rooms away but it always kicks on when we use the gas stove or when the heat kicks on. Setup was super easy too.

I bought this device to clean up the air after I do my holiday cooking. I am also looking to significantly reduce the dust in my house. So far, it is performing exactly as advertised. The cooking odors do not linger, and I have a fresh and pleasant-smelling home. I am very happy with this purchase.

[This review was collected as part of a promotion.] The SHARK " Never Change Air Purifier Max" (Model: HP302) with adjustable odor neutralizer technology, 4-layers of filtration system (high performance nanoseal HEPA, activated carbon, medium particle and debris defense) efficiently self adjusts its fan speed based on the air's pollution level while still running insanely quiet. Furthermore, the unit did an excellent job clearing the air while doing frying - not only in the kitchen area but also the adjacent dining room, responding in real-time and automatically reacting to prodigiously purify pollutants and odors in minutes. Bottom line, the stunningly aesthetic Shark Never Change Air Purifier Max does a phenomenal purification of indoor pollutants and odors.

[This review was collected as part of a promotion.] This air filter is a little machine and much better then the hunter air filters I previously had in my apartment, I'm extremely allergic to dander, dust, animal hair and this keeps that to the minimum without any hassle! Plus the fact that the filter doesn't need to be changed every month is incredibly convenient! Well worth the price tag.

[This review was collected as part of a promotion.] I wanted to give this thing a fair trial. Being in the kitchen it kept reading 0% clean air. It was near the litterbox so we gave it a pass. Our closet has had a smell since we installed shelves so I figured a small enclosed space would be an easy test to see how well it works. We have an air quality sensor that we compared it to. As you can see the ACTUAL particals per million are far less than the Shark purifier reads. It has been in there for a full month and the “air quality” has not changed. There also is still a woody smell from the shelves. So not only is the sensor absolute garbage, so is the purifier itself. DO NOT PURCHASE THIS. *I was given this product for free by Influenster in exchange for my honest review.

[This review was collected as part of a promotion.] I received this as gratis from influenster for free for my honest review. This thing tests the air quality and cleans the air based on that. We put it in the basement with the cats and it has been amazing for the air quality down there!! It went from 30% to 100% and runs quietly too! I would recommend this to anyone with allergies or poor air quality it definitely does the job! Easy to use!
