[This review was collected as part of a promotion.] Very easy to use and very convenient that the filter is high quality enough to last for years so that you don't have to change it all the time. It's also great for adding airflow to the room especially if it's hot. The display is easy to read and a great tool.

[This review was collected as part of a promotion.] I really enjoy the Shark NeverChange Air Purifier. The purifier is user friendly and easy to setup, including the Shark Odor Neutralizer. The changing of the air filter is straightforward as well. The purifier is also light and quiet. I also like the design and functionality of the purifier. The color LED display is a great addition allowing you to monitor the air quality. I do wish that the side handles were more secure, since it can make moving the purifier around slightly difficult but it's still fairly portable. Since using this purifier, I have noticed the freshness and odor elimination that the purifier provides. Overall, The Shark NeverChange Air Purifier provides great benefits and I'm satisfied with its performance.

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.

When we first plugged it in it stayed on 100 % air quality without fluctuating, so we thought there was something wrong with it. But then, we cooked a meal in the kitchen,(the unit is in the next room) And the air quality went down, the unit came in and stayed on until it was 100 % again. Highly recommend

[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've had air purifiers in the past but this has been the best one I've ever used. I keep it between our kitchen and living room. Anytime I have an odor in the kitchen, it works so well at making the odor gone fast!! I love that it shows the percentage of how clean your air is. I keep it on auto because that is more energy efficient. The max is very loud so you wouldn't want it on that all the time. It is large but that isn't an issue with me. I love that you don't have to constantly change the filters. I highly recommend this air purifier!!

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.

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%.

Work great while they work. The "5 year never change" filters have to be cleaned and now after less than 6 months need to be replaced. I purchased 2 of these at the same time, and both of the filters are falling apart due to repeated (bi weekly) cleaning. Without being cleaning, the purifier says the room is 99% dirty and runs at full blast 24/7

[This review was collected as part of a promotion.] I love this air purifier. Well I guess I should've known because I love everything from this brand. It is easy to set up right out of the box, the instructions are clear. It works amazing! I had no idea it covered such a large area. I keep it close to mine and my boys bedrooms. It gives off the lightest scent, as it's working. But it's just a clean light scent. The display will tell you how clear the air is up to 100%. This has made a world of difference in my home.
