[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.] 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!

[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 review was collected as part of a promotion.] I love this thing. The gauge on the front that shows what the quality of the air is at is amazing! It definitely works too because the moment we start cooking the number goes way down and the filter starts working on over time until it gets back to 100. Helps keep dust away, and I think it helps with our cat hair (but I'm not sure bc cat hair still turns up everywhere). Also love that I don't have to change the filter so I dont have to keep up with buying the filters. Worth the money!

This is the best air filter ever. It is so automatic you just set it up and you never have to do anytihng else. I cooked bacon in the oven this morning and never realized how the smell affected the air quality until i heard the fan come on and looked at the air quality was done to 73%. Shortly there after it was back to 100%.

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.] Shark NeverChange™ Air Purifier MAX works really well. It really cleans the air in a large area-1400 feet. Ithas cut down on the dust and makes the air better to breath in summer. We were coughing even with the air conditioner going but when we used the air purifier the coughing disappeared. I know that it is going to work great in the fall and winter months.

[This review was collected as part of a promotion.] I received this product a while ago and put it in the corner of my living room. It was easy to assemble and runs so smoothly and quietly. The odor eliminator is a nice feature and the air feels noticeable better.

[This review was collected as part of a promotion.] Shark Never Change Air Purifier Max is the most modern air purifier yet! It is 2x better odor reduction that guards against odors and releases a fresh scent back into the room. This scent makes the home smelling noticeably fresh. This size is perfect because it takes up little space while looking great and covering 1400 sq ft of area. That's two rooms! The filter is one of the best parts because you do not have to change it for up to 5 years!! That alone saves you up to 300+ on filter costs. Four layers in this machine captures 99.98 of allergen and irritants. There is more. The cleaning sense IQ feature will sense changes in air quality and automatically reacts & improves while giving live updates. I am telling you, this is the best filter you will ever own!

[This review was collected as part of a promotion.] I felt like the air in our house is always dusty and I have no idea why! I've been using this new filter for a little while and it's helped to make a huge difference in our air quality. There is practically no assembly required! I love that there is a child lock for the buttons and it's super quiet! I've been keeping it on auto mode and I don't have to worry about it. I put it out in our refinished shop and it started out at 65%, yikes!! So now I defiantly need a second one!
