I really like this unit. It really does its job by cleaning the air. Its very quiet and has a few modes that increases the fan speeds when it detects unclean air. My only bad thing I have to say is that my previous unit came with a remote control. This unit does not have it. It would be a nice addition for this unit.

[This review was collected as part of a promotion.] I received this air purifier cause we have a large room and 2 dogs. I had no idea what I was missing and wish I had known og this air purifier a long time ago. Now that I have one I will never be without one again. No matter how much I cleaned or what I did I felt like my house was constantly smelling like pets. Even an hour after a deep clean(once the smells of the products wore off) all I could smell was pets,between my cat and my dog. I like candles and wax melts but don't want to have to run them constantly. I needed to solve the problem of the smell, cleaning wasn't enough and I love my pets I didn't want to get rid of them! Let me tell you, I have had the shark for less than an hour and no dog smell! I am so happy! The air feels fresh to breathe, the machine is quiet even on max power it's easy to toon out, good easy size for my small house. Will be telling all of my friends they need one as well very happy with my purchase. Hopefully it lasts a long time.

I've had the Never Change Max running for a few weeks now. The air smells cleaner and the unit automatically adjusts when something changes. I had something on the stove that created a little smoke and within seconds, the Never Change Purifier increased fan speed and showed an 80% air quality. The fan gradually slowed until the smell was gone and air quality was back to 100%.

I'm not sure if this air purifier really cleans the air. I was sure my air was contaminated with dust and cat hair/smells and was surprised when turning it on for the first time and getting a 96% air quality. Never thought my air was that clean, so I bought this air purifier. Can't really tell any difference in my allergies. The purifier is and the airflow seems fine. But is it really doing anything? Or just displaying that my hair is good? Wish there was someway to tell.

We got our purifier in about 2 weeks ago and it works wonders!  We have 4 dogs so we needed something to keep our home from smelling like....well, dogs.  This has definitely made a difference.  Considering buying one for other areas of our home.  I also like that it cleans the air after cooking.

My doctor recommended that we buy an air purifier for our house to help reduce dust. The timing of our order was perfect, because right when it arrived, the smoke from nearby wildfires was blowing into our area and the air quality took a dive. Our house feels so much nicer now and keeps it clear of all of the usual dust and dirt particles, as well as wildfire smoke. (I also have to add: the little chime is has when you push a button is absolutely darling!)

[This review was collected as part of a promotion.] I bought this about a month ago because, My family suffers from indoor allergies as well as pet allergies. When it is shedding time everyone struggles. However this Shark air purifier makes the air clean and fresh so we can breathe easy once more. I really like the look of it, it fits nicely with any home decor. The touch top and controller can be used separately or only one. When fire season kicked up smoke in the air the indicator let us know how bad it is as it cleans. I like being able to see it change slowly until it reads 100% clean. Also, has an air freshener which is optional if you want to use it or not… i would definitely recommend. This has helped everyone tremendously. Allergy season has stopped bothering us for the most part when inside. It is super easy to use and works amazing. I am impressed with the quality and will be purchasing another for the downstairs. The air is clean and everyone in the house feels better.

[This review was collected as part of a promotion.] I got this a few weeks ago and it has been amazing. I recently moved into a new apartment and the tenant below me smokes. I used to sometimes get wafts of smoke up from the downstairs and they would smell so bad. Since getting this air purifier I no longer have this problem. The smell eliminator on this thing is amazing. I think the design is also really ingenious. They designed it so that the filter never really needs to be changed and so that there are two washable filters that catch most of the debris. Another fun thing to watch is since my stove has no range hood, I can watch the unit as the particles in the air increase. It goes from blue to yellow to red as the air gets more and more particles and then after I finish cooking it slowly scrubs the air clean. This is a great product and I suggest it to anyone.

[This review was collected as part of a promotion.] I absolutely love my Shark NeverChange Air Purifier MAX. It is very quiet. It is very sensitive. I can spray perfume or turn on a Scentsy burner in another room and it immediately can sense the smell in the air and goes to purifying. At that point it doesn't take very long before it cleans the air. Every time I walk into my home my home smells clean. I highly recommend this air purification system.

[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!
