Air Purifier 4 with Anti-Allergen Multi-Filter Advanced Odor Lock and Smart Sensing (HE401)

We bought this purifier about a month ago to replace a smaller lower end unit. It was bought for the sole purchase of cleaning the air in our home, more specifically this one is for our Master bedroom. I suffer from mid stage COPD and was directed by my doctor to have at least one higher end, dependable, Hepa air purifier in our bedroom, and also one on each floor of our home in the common living areas, to help clean the air so as too aid my breathing and help my lungs process cleaner air/oxygen easier. I Love it! It is powerful yet quiet on the lowest setting, so it does not interfere with our sleeping at night. The controls and settings area are easy to see from across the room. It is simple and straight forward to operate. We do have a cat box close by to where the purifier is sitting, and it does reduce the severity and length of time you smell it, when a cat uses the litter box. It is a little Pricey, but after a month of using it, we do think it is worth the price. It has aided with my breathing at night with and my COPD issues. We can definitely feel a big improvement in the air quality in our bedroom since buying the Shark and using it instead of the smaller loer end purifier we were using before. We highly recommend the Shark 6 Fan model, especially if you're dealing with Lung and breathing medical issues.

I’m a huge shark fan but this air purifier is definitely the best one I have used! I love that it has an auto system so that it cleans and runs how it need to clean the air! I also love that it gives a % to the air quality. My husband has bad allergies so we have tried lots of purifiers and this one is helping him the most!!

I love how quickly The Shark Air Purifier 4 picks up on odors in the house. The clean air read 100% in the room. So I left out and went into another room and sprayed perfume on myself. The minute I opened the door and went back into the room where The Shark Air Purifier 4 was, it automatically picked up on the scent, and the clean air percentage started going down immediately. As clean air percentage started to go down, The Shark Air Purifier 4 started to auto-adjust power to clean the air. If I am cooking downstairs, it picks up on that and starts quickly cleaning the air in the room to get any of the smokey cooking smell out. And you will be able to tell the difference in the air quality. It helps with my son's allergies a lot. The Shark Air Purifier 4 is worth the money, and I highly recommend it. I am so happy that I purchased it. The Shark Air Purifier 4 quietly distributes air through 4 powerful fans. Clean Sense IQ technology tracks air quality & auto-adjusts power to constantly maintain clean air in your home. A Shark Anti-Allergen HEPA Filter captures airborne allergens, dust, dander, and particles. Advanced odor protection guards against cooking smells, smoke, and more. Cleans spaces up to 1,000 square feet.

Smoke, cooking odors and pollution from the street in NYC was driving me crazy. 90%+ gone now. Tried several other air purifiers, this one worked the best. Pricy but worth it.

Pretty awesome when we are grilling or cooking dinner and the house gets to smelling like what your cooking. It kicks into to high gear and starts filtering away. Not to mention when your dog might have gas it works on that too

Just opened the box, plugged it in said the air was clean… great let’s take it outside and WOW 100% clean air outside also

[This review was collected as part of a promotion.] I was concerned about the air quality of my home and was looking for a good Air purifier that can purify indoor air. I am impressed with the quality of Shark Air purifier. It comes assembled and ready to use. Also, It is rectangle in shape and not too heavy. I was intrigued by Clean sense IQ technology and wanted to see how it works. When I plugged it in the living room, it tracked the air quality and showed it in the color on the display. And, when it ran for a quite some time, the air quality came up to 100% and displayed in the blue color. I liked this technology, where I can see the air quality of the room being improved by the purifier. It has 4 high speed fans, that cleans the air at a faster rate, and are not loud. It gives me a piece of mind that it has an effective anti-allergen multi filter. Moreover, it comes with an easy to use remote, which is convenient. Its a powerful Air purifier!

[This review was collected as part of a promotion.] This air filter cleans the amount of pm2.5 and pm10 in the air. The well lit screen notifies me how much of each is in the air. As well as a timer, the filter life, and the percentage of clean air. The screen is able to be dimmed or turned off totally. There’s 4 speeds which are controlled from the screen or the remote. The lowest speed is almost silent. The filter is on the back of the air filter and is easy to get to.

[This review was collected as part of a promotion.] I absolutely love this shark air purifier, it really makes a difference in our homes air quality! We have two dogs and this helps so much with dander in the air. It is also very good quality, it it touch controlled or also has a remote, I also love being able to see my air quality at all times, lots of features can even show you the filter life.

[This review was collected as part of a promotion.] The Shark Air Purifier w/ Anti Allergen Multi Filter ADV Odor Lock and Smart Sensing is an amazing machine and I would recommend it to anyone with allergies or concerned about air quality. In the age of COVID, I loved having this machine to clean and purify the air in the main area of my home and in my bedroom. The air feels so much lighter and cleaner when I run the Shark Air Purifier daily.
