Customer Ratings & Reviews

Great product, easy to use, and lets me know the air quality of the area it is in.

We use this on the main floor of our home, and it has helped reduce allergens for me and the family, and even filters out most pet odor.

great air purifier. my cats jump on it and like to turn it on and off so if you have a couple furry gremlins running around that'll happen. If your brother does 8 b0ngs a day this thing will have a heart attack each time.

Shark Air Purifier 4 works great for allergies. It is a great item to have if you are coughing and hacking all the time due to allergies from pollen

The auto mode is nice! It's quiet on the lower speeds but you can hear it when it goes on high. We noticed a difference in the air quality

Not only has the air quality improved, but also the odor. I leave it on all the time on auto and does a great job of handling a large space

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.

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.

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!

This item works great and it is super quiet. It is bigger than I expected, but it is slim and looks good sitting in any room. It has a nice, simple design and the auto feature works great for it to run when it needs to. When I am cooking, it kicks on to get the smoke out of the air. When it kicks on, I can hear it when it goes to high, but it’s not overly loud or annoying at all. It is a subtle sound and kicks down to low shortly after going to high and the low speed is very quiet. I definitely notice a difference with the dust and dog hair in the air.

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

This air purifier is very quiet at low speeds and kicks in as soon as it senses odors. I keep it in my kitchen, and it keeps odors to a minimum while cooking and clears the smell quickly.

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

Overall I love it. Bit spendy, but it does everything I'd ever expect an air purifier to do. One caveat--I haven't researched replacement filter prices yet so I'm not sure what those cost. Pros: -Very quiet at the lowest fan speed -Auto setting works well, spinning up the fan speed based on particulate level of the air -Appearance, it looks nice but unobtrusive -Countdown for remaining filter life. Not sure how this is calculated though. Cons: -It'd be great to have an adjustable program for the auto setting. Sometimes I disagree with what speed the fan should be at or how quickly it reacts.

I love this air purifier, it has helped my allergies greatly especially being in an apartment.

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.

Looks to be a good air purifier with a lot of features, and adding convenience with a remote control. It also looks very nice that would add a great decoration to your room.

Use this product every day and simply amazing. Clean air quality inside house whenever it’s needed.

Excellent air purifier that has worked very well each time initiated. Continue using as needed.

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
