I absolutely love my shark never change air purifier. I have the large one that does 1200 ft. I never realized how bad your air quality gets when cooking. I have this sitting in my living room and when I'm cooking it kicks on and the air quality is down in the 60's! Doesn't take long for it to get back up to 100%. When you walk by and see it says 100% it gives you a sense of calm knowing you're breathing the best air possible. I've decided to buy a small one for my bedroom. ❤️ 🦈

[This review was collected as part of a promotion.] My living room is open concept and usually I need multiple air purifiers for this room. This one can handle the job. You'd be surprised how at how much normal cooking with a gas stove can impact indoor air quality. This unit gives you a lot of information about what type of air pollution you are experiencing as well as the air quality. I like to use on “auto” mode so it's set and forget. It has been set up for months now and still works great. Haven't had to do anything!

I have had this thing for several months and there really is no rhyme or reason to why it comes on or goes off. It basically detects faint smells (good or bad) and comes on. It does NOTHING for dust, as the dust is collecting around it months later. It just doesn't do what I assumed it was supposed to do.

[This review was collected as part of a promotion.] This air purifier is extremely quiet. We have a 3,500 sq Ft home and this air purifier does the trick for the first and second floor. This purifier also allows us to have the windows open and in our experience, minimizes allergy symptoms due to the fresh air. We notified an immediate positive difference in how our home smelled after using this machine for a night. Set up is super easy, just unpack it from the box, put it in the corner and plug it in and the machine does the work!

[This review was collected as part of a promotion.] I live in Minnesota and recently the air quality got worse since there are forest fires next to the Canadian border. This Shark Air Purifier unit gives you more than an average home air purifier. It's not just high performance up to 1200 sq ft, smart technology, real HEPA filter and so on. It is a quiet, powerful and well designed unit. I recommend it for every household especially if you are sensitive to the air quality in your living space.

I absolutely love my new Shark NeverChange Air Purfiier MAX - leaves my home smelling great! I may partake in marijuana from time to time and it leaves my house smelling of it. Not anymore! I love that right after we partake the indicator on the device goes red....and within minutes back to blue - pure air and house smelling clean again! Really like the idea that there are no filters to purchase! Easy-peasy! Low maintenance! Did I say I love it? !!!!

[This review was collected as part of a promotion.] I am impressive with the features on this air purifier. The permanent filter will save me money. Thr on board controls feels new. I love that it tells me how clean my air is. I can have it run all thr time or use the timer. Includes a little separate filter for odors. It disperses a mild scent that is pleasant. It is pretty quite too! I love it! I find myself dusting less too since running this. highly recommended!

I bought two of these air purifiers. The two big takeaways are: 1) They are highly efficient and very quiet! They only turn on automatically when the air analyzer identifies that particulates in the air need to be removed. This saves primary energy use and keeps the air fresh. 2) They have integrated scent production using remarkably well-priced scent pods. Makes the rooms smell really nice but not with overpowering scents. A definite benefit. The purifiers put Hunter purifiers to shame.

[This review was collected as part of a promotion.] I really like this Shark Air Purifier. It is very easy to set up and it runs very quietly and covers a large area. It has a display that tells you the air quality along with a touchscreen that allows you to select different fan speeds. I also love the fact that you don't need to change the filter. Our house smells fresher since we have been using this.

[This review was collected as part of a promotion.] Just the fact that this filter doesn't need replacing for five years, is an absolute win! Both the unit and filter are large in size but so is its range of fourteen hundred square feet. This air purifier couldn't have come at a better time as our air quality levels in Michigan have literally been in hazardous range on and off all summer. It also helps keep all the dog hair out of the air, and off of the furniture with its suction and two pull out screens to keep it away from the filter! I am a huge fan of the lock feature, making sure once I have it set, my little one doesn't change anything! I can smell the difference in my home, it has the same odor neutralizer in it that my Shark vacuum does, and I love it in both products. Nothing makes a mom feel better than her little one going to sleep soundly, breathing in the freshest air possible!
