Very quiet , decent scent feature but the scent does not last long , very nice auto setting feature that increases filter fan when poor air quality detected

Wonderful product! I searched many different types of large room air cleaners and came upon this one. We have had it in operation for a few weeks now and it is doing great.

On auto it rarely runs. If you cook something in an air fryer or an oven it senses that and comes on pretty quick. I may just run it on medium/high and just change the filter yearly. I wanted a reduction in dust not smell.

Love this air purifier. I am allergic to cats and have 2 living in my house, thank goodness its not a severe alleegy but constant exposure is not good this purifier helps.

I bought this air purifier because I was tired of the plug ins and candles with the overly sweet and floral scents. Now my home smells fresh and clean.

Broke after 5 days, making a horrendous squealing noise whenever running. Called for support and they couldn't replace it for a few weeks, called back and they still cannot replace it. I'll be honest I'm getting pretty mad at the whole ordeal.

The cost/poor quality of our old cleaners made the decision to buy the Shark NeverChange EZ! The Shark NeverChange does such a great job we could easily tell a difference within 24 hours of plugging it in! Thank you Shark

In a world of so many air purifier choices we simply need something that works. We trust the Shark Ninja name and Sam's for quality. We can tell the positive difference this air purifier is making in our home that we share with cats.

When I first set this unit up, I expected it would turn on showing poor air quality because I have two dogs in my house but it started at 100% air quality. I thought I got a defective unit but a couple days later I was frying some fish and the sensor turned red and automatically increased the fan to filter more air. A few hours later the dial was lit blue again and showing 100% fit air quality and the fan automatically went back down to its silent operation. The only time I hear this running is when it increasing the fan to filter more air but even then it's softer than most fans. Since the filter shows 100%, except if I cook something with a bit of oil in the pan or use my air fryer, I turn it off in my livingroom at night to save energy then turn it back on when I get up in the morning. I'm pleased with how quiet it is and that my air quality with two indoor dogs is very good. I expected it to show lower quality until it had been working for a few hours. The one thing I did notice is that the scent pods that came with it didn't really add a scent to the room so k don't know if these were more of a scent neutralizer or if they were intended to add a fresh scent to the room. I just don't notice any difference so I may try the lavender or maybe eucalyptus next time to see if I get a scent. All in all; the product is working well and I like that there are screens that are washable and keep some of the dust out of the Hepa filter so it shouldn't need to be replaced as frequently as other filtration systems.

It works very well as far as I can tell. When in auto mode with good air quality it is almost silent. I have not have it long enough to judge the durability of the filter. I wish it had however a wifi/bluetooth capabilty with app to control it/review info
