Works great, especially with one GS German Sheppard 3-year-old. Easy setup and working great removes all odors in the entire living room and dining area as well! Recommend purchase!

This is the fourth one that's I've gotten due to other three not working and I still have the same problem. The sensor stays at 100 percent and doesn't move.

Not even 3 months and filter needs replaced.  My Shark Never change air purity did not work as advertised.  It has been less than 3 months and it quit filter and needed a new filter.

The smell of the odor neutralizer cartridge is disgusting. It literally smells like a public bathroom urinal cake. The fact that they don't offer different scents is insane. I specifically purchased this for this feature so I'm returning it.

It's costly & hard to find replacement filters on other air purifiers. This Shark has a permanent air filter which monitors the air quality automatically & works quickly & efficiently. There are various settings including an auto mode which monitors the air quality & increases automatically to maintain a good air quality range. This is an excellent buy if sold for under $300 as smaller, less efficient purifiers that need replacement filters sell for more than $300.

3 stars for misleading product name. While it is a great air filter and deodorizer you will need to eventually replace the main filter cylinder. There are washable screens the air passes through that help extent the life of the main filter. Depending on how dirty your local air is will effect when you replace the filter.

Works Great! The odor neutralizer was very strong when first inserted, so since unit was used for a sensitive person with lots of allergies we removed that. Like so much purchased a second one! The fact that the numbers dropped so much when popcorn was popped in a bag in microwave, and when bacon was cooked dropped down to zero. It was eye opening! Sooo quiet, super easy to use, and sleek looking!

I bought 2! They take even the good smells out of the air! They run all the time as I have plug inns and wax melts going. I want it to leave the good smells behind! I haven't bought any other product to compare it with but definitely cannot speak ill of them. I haven't bought any dogs and in just three weeks cannot believe the difference!

This sensor did nothing when I sprayed cleaner or air freshener near it. Still showed 199 percent clean air. It did react to blowing smoke into it. The air freshener pack smell is not noticeable unless I have my nose right at it. I'm not sure it works well as animal smells are not cleaned. The carbon should be cleaning animal smells. My blue air one removes odors whereas this shark one doesn't seem to. I do like the size and quietness of it. My house is less than 1400 sq ft so it should be cleaning my whole house but it doesn't seem to be fresh even though the air quality shows 100 percent.

I have used this air cleaner for 6 months and am extremely satisfied with the performance. It is easy to set up, easy to use and easy to maintain. I bought a hand held air gun for cleaning electronics and it works great to clean the removable screens. I noticed a difference soon after installing it. I am considering a second one for the second floor.
