Customer Ratings & Reviews

I have a Shark vacuum and I like their technology. I was drawn to the engineering of this air purifier. The 4 fans vs 1 bigger one, the ease of one filter to change, and of course the dual LED read outs. We’ve had the purifier for 2 weeks or so. I purchased more to clear out allergens in our home, but as I turned it on it different rooms, including the bedroom where our dog sleeps, it always has shown 100% clean air. Since we have used it, I feel like the air is clean and crisp, but am I feeling that because the read out says 100% or is the air clean? The jury is still out.

I like the percentage it shows as the room improves. Quiet on the lower settings, highest setting is a little loud to me but I certainly think it helps

Works fantastic, i keep mine centrally located in the house. Fans are powerful yet quite, you will notice a difference in the air quality.

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).

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.

Better than I thought†*********,,,********************

Works amazing, very quiet and within a day of use you can tell a difference. Extremely quick and easy for setup. The auto function works perfectly!

It certainly works. Cleans the air fairly quick after cooking. Planning to buy another unit when and if I catch it again as a daily deal.

The Shark Air Purifier 4 does an excellent job of purifying the air. I like all of the advanced features offered on this purifier. it does its job!! The only con is the loudness of the machine when it's purifying the air on "auto".

Works great so far have cooked a few things and takes care of the odor in no time. Wife also seems to breath better since got it.

It works, it is quiet when not on high setting and it is good that the indicator lights can go off when it is dark

I have to say before I bought this air purifier, I never paid attention to all the trivial things that can change the air quality, outside of anything that your nose picks up. The things that trigger it to purify I would have never noticed but now I do. I breathe better and I pick up things that were once subtle. The Shark is a solid build with great quality, and it does the job no matter how big or small. The indicators on the machine are well thought out and the auto settings gets everything taken care of.

It really does work well, The house stays fresh, cooking odors disappear quickly and it has really helped with allergies!

The shark air purifier works well and cleans the air in a large space. Very quiet and efficient.

works incredibly. filter is easily cleaned. Love seeing the little graph of cleaning quality at the moment.

I love most Shark products and this Air Purifier works perfect in our bedroom. Doesnt take alot of space and works great.

Helps my allergies, reduces dust in the house. I have two dogs who shed a lot . Also helps with cooking odors.

We bought three of these when they went on sale and they have been incredible! We have 5 dogs and lots of allergies from pollens in our house. You would never even know we had dogs with these air purifiers! It doesn’t smell like dog in my house at all! I wanted to see if it really told you the air quality so sprayed air freshener in my room on the opposite side and the air quality gauge went from 100 to 99. It really works!!!

This air purifier does not disappoint! It's the perfect size for a large bedroom or family/living/TV room! It's very quiet and unnoticeable and the rectangular form gives you much more freedom for placement behind a couch or table so it can be hidden. The auto feature is incredible and the percentage of air quality is fun to see. It feels gimmicky at first as if I know what 85% air quality means, but if you really observe for a few days you will notice that the purifier really does detect air pollution. Whenever we blow out a candle, the purifier quickly detects odor and smoke and turns onto a higher setting. There's other useful settings and plenty of features to play with but I found the automatic feature to be simple and easy. All you have to do is plug and forget. Generally, when used in a bedroom, I do feel a big difference in air quality when I sleep and wake up in the mornings. No stuffy noses or puffy eyes, the air feels lighter and easier to breathe. I can see this being the perfect device for someone with seasonal allergies. Also big plus for pet owners, huge difference in general odor in the air. I have 3 dogs and their scents do not linger. This is a great purifier for any home.

Works good for whole house or just your room long filter life is nice and it’s very quiet if not on high
