Customer Ratings & Reviews

This air purifier has 4 air intake fans maximizing allergen capture and it's slim unlike other purifiers. This one has a flat filter.

This is a wonderful device. It is very quiet when in normal mode, but is a little louder if it senses something in the air and automatically adjusts fan speed, but not too loud. Tells when filter should be changed. Very sensitive to changes in air quality and can automatically adjust fan as needed.

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

It works great and definitely helps with odor too!

I bought this for my sister's townhouse & she loves so much that she wants to buy a second one. It's well & continues to work. I bought the Shark Air Purifier 6 Fan version more than a year ago & it continues to work well every day.

I love the auto feature. It ramps up when needed and the back down to almost undetectable when running

Honestly probably one of the best air purifiers on the market no exaggeration. The fit function of it and build quality for maintenance is killer the monitor system for being the air and setting is great dead silent for normal use and the

I love this thing, using it on my newly remodeled home it has helped so much with dust and keeping the air clean and fresh. Also great filter lifetime, my house was so dusty from construction the airpurifier is running nonstop for 2 weeks and still has around 175 days left. Great product!!!

Have had this Shark unit for almost a month. Says the filter will last 6-12 months, we will see about that. I have 3 dogs woth lots of fur and dandur and this seems to help with the allergies. Doesnt get rid of pet smells, but does filter the air. So far its doing exactly what I needed it for. Will update as time goes on.

This is a very efficient air cleaner and good for people with allergies, asthma and pets in the home. Easy to set up and the filter is easy to change.

Highly recommend. It is quiet, compact and has a stylish design. The displays are also easily visible for monitoring the progress of your clean air in percentages. Powerful air purification with multiple fans.

This thing is awesome! I can finally breathe in my home with 4 dogs. I love that it senses the air and adjusts the power Accordingly. It’s extremely quiet too.

Works great! Noticeable difference in the air right away!
