Shark Air Purifier 4 True HEPA with Advanced Odor Lock

Couldn't be happier with this air purifier. Love the way it tells you the quality of the air. It is so accurate that it detects when I'm cooking, have a fire in the fireplace and even when dusting. This is my second one. The filter lasts a long time too. I've had the first one since Christmas and still haven't changed the filter yet. I have one in the basement and it will detect a fire in my fireplace. The only negative is the price and the price of replacement filters. But if you want quality it's costs money. It's worth every penny if you want clean air.

I have a chronic allergic reaction to poor air quality, which causes constant sneezing, runny nose and congestion. Until we purchased this device, the only temporary relief came from taking nasal decongestants, which caused brain fog and other unwanted symptoms. This air filtering device continually monitors our air quality and makes adjustments accordingly; my sinuses have never been so peaceful! After all these years I am able to breath in clean air without sinus aggravation…what a relief!

love the look and easy to operate. Also when we are cooking or dog is in the room the air quality drops so I raise the fan and it moves back to better quality after a bit. This gives me a gauge that it is working and making a difference. Also my family noticed they breath better feels cleaner ordered another one for my daughters home. I need to get replacement filters ....hoping they are not to expensive! They should be offered when purchasing so we know how much and how often we need to change.

This is a state of the art machine! It's got just the right amount of options so I can run it the way I choose. It has a remote control, it's quiet and powerful. Sleek design is attractive and unintrusive. High quality.

I totally love this air purifier. I have noticed we sleep better, we have less coughing. We had smoke from our fireplace and we watched it change and increase fan speed automatically. We both liked it so much we bought another one. The filters are pricey but should last approx. 6 months. I'll know more when 6 months occurs. Also I've noticed that I have to dust a lot less.

These purifiers are great. I purchased 2 to cover my entire home and they are really quiet. It's amazing to see them speed up to clean the air when there is an odor or dust detected. In just minutes, it is back up to 100% and the smells are gone. They are thin and look stylish. I like that it tracks the filter cleanness and will tell you when to replace.

we have had this purifier for 3 weeks and we love it. It is extremely quiet while moving large volumes of air when needed. We like the simple display and the information about air quality is great. We have been very pleased with this and hope that it will continue to exceed our expectations! (PS liked it so much we ordered the larger one for our house as well)

Works exactly as claimed! Excellent in removing pet and cooking odours; seems to be reasonably good at removing pet hair (for reference, I have a golden doodle that is mostly golden retriever). Interface is intuitive and easy to navigate. I especially like that there is an automatic setting and that it tells you the number of hours of life left for the filter — the biggest perk being that you only have to replace the filter every 6-12 months.

This unit will show the percentage of purified air in the room and cleans the air quickly. Unfortunately it does not remove cooking smells from the air (onions, garlic, and fried food smells).

I'm really uncertain if I trust the readings. It was super easy to setup and is very user friendly!! Its sleek looking and very quiet! The reason I'm uncertain on the readings is due to it reading 100% clean air for the first 3 days we had it running. I know we had at the very least dust in the air.
