Customer Ratings & Reviews

This Air Purifier is excellent for people with allergies. It eliminates bad orders or allergens that moght be in the air, makes it better for me to sleep at night.

It works great with cleaning the air at my house. The smell of fried foods no longer linger since I've purchased the air purifier. The only thing I dislike is how loud it is. I wish it was more quiet.

Excellent product very efficient and effective highly recommend

I love it! The first two settings are so quiet they really can’t be heard. Our allergies have improved immensely and it keeps my home from smelling like dogs!

Living in the city in a rather dusty area this Shark air purifier 4 has done an excellent job of purifering the air and keeping down the dust. I am well pleased!

Excellent air purifier. It picks up pretty much any changes in the air. Even with it being in the master bedroom across the house, it will go active, if it picks up cooking odors from the kitchen. I do have to turn it off at night, because I run an essential oils diffuser in my bedroom, and that will send the air purifier into overdrive. VOCs are VOCs, regardless if they are the kind that are good for you or the kind that are bad for you, so that explains it trying to eliminate the essential oils from the air. It just shows me how sensitive the air purifier is. I knocked off a star, only because the filter doesn't seem to last long. It is now roughly 9 months old, and it is already signaling that it needs a new filter. They are kind of pricey and sometimes hard to get, so I'm not looking forward to that purchase. But, it is a very effective air purifier.

I’ve had this purifier for a few days now. I must say, it’s got a simple control setup, makes the air in the home fresh and is not that loud even on its highest setting imo.

Very happy with my purchase. It does a very good job cleaning the air.

Instant improvement on the quality of air in our home. The house is coming up on the century mark and has always seemed dusty but with this air purifier we are not seeing nealry has much.

best purchase i have made in a long time. keeps the air smelling clean and helps with our allergies and sinus issues

Shark has done it again. I couldn’t resist the $199 price. I should’ve gotten two. It’s pretty cool to set it to auto. Very quiet and you won’t even realize that it’s on. It does the job

So far it’s working as intended. User friendly setting, not too noisy for the size and coverage of the unit, and covers good area.

Love this product! Covers a large room and haven’t had bad allergies due to the clean air. It’s quiet and doesn’t take up space (slim design).

I love this air purifier. It really does a great job when u see that filter. I'd like to get 1-2 more for different sections of the house.

I got this on a deal of the day so I didn't pay top price but it is a top-notch purifier! I have a parrot and things can be dusty. Though I was skeptical about it, I've kept this on "auto" and by golly it does turn on when the heat or air comes on through the floor ducts, or the bird "fluffs", or sometimes even if the doors are open. I use several Shark products so I was comfortable purchasing this.

I got this right before I found out my mom had COPD/ and it has done wonders to the air quality in my home. My plants are thriving and my moms cough has diminished

amazing, this purifier makes the air much lighter and more pleasant to sleep and enjoy your stay in your home.

I have 4 cats and when this is on its like i have no cats

Truly eliminates for and helps with dust! We are really happy with the results!

This is a very good product which cleans the air as well as limits dust amounts. One of the best features is that you can adjust it to turn on automatically.
