Excellent air purifier for clean air. It constantly checks the air quality and turns itself on and off when it is set to auto mode. It is also pretty quiet for the amount of air it cleans. The main hepa filter lasts for 5 years. Hopefully it doesn't cost too much when it needs to be changed. However the two side filters need to be cleaned regularly.

After a few months our unit began to have a high pitch whistle. We clean the unit once a week and we're dumbfounded by why it was doing this. I took a lownpressure air nozzle to the entire unit and still it whistled. I wiped the accessible area with a microfiber towel, no change. I called SHARK and after they saw and hears, via video chat, the issue, they immediately sent a replacement. I hope this new one doesn't begin to whistle in the next few months. We love SHARK. They are amazing at replacing warrantied units. Always get a warranty, I've used for every SHARK unit we own.

Purchased two hoping to see a difference in the air quality In our bedroom and house. Pros. *Whisper quiet most of the time on auto. *Easy to clean * Ships fast Cons. *Price *Not sure it's actually cleaning the air my cheap filter seems to catch more dust and pollen. *The smelly cartridge to make the air smell clean is out in days even on the lowest setting. This is a short term review will update after a season of use.

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.] We've been looking for something to help the poor air circulation in our apartment, and are very happy with this product so far! My favorite feature is the long lasting filter (5 years vs ~6mo life). Another favorite feature is the air quality indicator! Overall, I'd definitely recommend this product over other air purifiers I've tried in the past!

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.

I purchased my first one around the middle of December 2024. Getting it set up was extremely simple. We have 4 dogs and 3 parrots so the pet dander and bird dust is heavy in our home. After 1 week I cleaned the screens that were completely covered and pulled the big filter and swept that off. It didn't show that it needed cleaned, but I figured it was going to need it. It worked so well that December 26, 2024 they went on sale and we bought a second one. I've noticed that the first one isn't running on high anymore and the air is 100% better. I highly recommend this product

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%.

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.
