I just bought not to long ago! As soon as I turned it on you could tell it was working!! Best air purifier ever! We love it.

Fan whine drives me nuts. Stays at 100 room quality air. I wish my air was that clean in the dusty desert. Not effective and annoying, it's getting returned.

Have used this every day since it was delivered. I am still seeing dust in the room it is placed/run! Seldom does it show less than 100%! This from day 1! All in all what it states it does so far does not show!

Just received my unit today. Was looking forward to getting it setup and running. Went thru all the quick setup instructions. Plugged it into the wall----NOTHING! Dead on Arrival. Returned to the store before the shipping status even updated.

It's been almost a month and so far so good 😊  I've noticed there's less dust on my furniture which is great  I deal with allergies and asthma so will see how it goes over the summer

Grast price. The air purifier works great. Any time there is a change in the air...oen sliders,cook. The shark goes t work. I have it on aut ad wll cean the air when needed. Great product.

I just purchased this air purifier and noticed that within hours it was working great my house is not that big but it is cleaning all of the rooms I recommend this product

Amazing product. I never knew cooking decreases the air quality in the house. Anyways, I have 2 Pomeranian and 1 Samoyed. The shedding made my indoor allergy so much worse. This purifier is amazing! My nose is not stuffy anymore.

I bought two of these for my home, and they have made a huge difference! No more lingering cooking odors, pet odors eliminated, and a light pleasant scent emanates from the unit. I definitely recommend!

I did a lot of research before deciding on my Shark Air Purifier. Keeping in mind reviews questioning whether it works or not, I was wary when my Shark had air quality 100% to 99% consistently. I decided to give it a couple of weeks anyway. I had my doors and windows open earlier today and noticed the percentage on my Shark was in the 80s. I checked the air quality for the day, and we had a poor air advisory alert for the day. Closed my doors and windows within an hour the air quality returned to 99% to 100%. So Yes, I do believe my Shark Air Purifier works. Being asthmatic, I usually check air quality if I'm going to be outside. I didn't realize how much it affected my air quality inside until my Shark kicked in and I could see the difference.
