If I could give this 10 stars I would. I have asthma, 2 guinea pigs, 2 dogs and a cat, I have had my share of air purifiers in my lifetime, even the really expensive ones that start with a D and end with a N, and lemme tell you this machine has been telling me I have bad clean air for a few hours as it did its thing, mind you, the room I put it in has a winix and a Dyson in it, I immediately can tell a difference in the air. I am a believer!

Love it so much that I ordered another. It's super quiet and I feel like it genuinely cleans the air. I like seeing the air quality reading on it at 100%. I know it works because we have ours set up near the kitchen and anytime we cook we notice the air quality reading drop some but soon after it gets right back up to 100%

Purchased this about 2 months ago and have only been able to use it for a few weeks. The big filter on the inside smells horrible! I have a fairly clean house it just gets dusty from a dirt road. I live in the desert so humidity is non existent. The filter smells like dirty feet, it is so disgusting. I've tried cleaning it and it still smells. DO NOT BUY THIS MACHINE.

I don't know what it is with some of these bad reviews I think its just people dont know what there doing. Mine works great when it wilk be at 100% and once you start cooking once that smell gets to it. It starts to go down. And sometimes it wont read anymore that means you just have to take out the 2 side fliter panels and clean then and then hold the reset button on the top and then it will read it again. And I took out the big filter to check it out and wow was it so dirty we only need using it since Feb 2025 that a good sign you know its working really good. So I would listen to these people with the bad reviews. I definitely will be buying atleast 3 more the smaller ones for the big rooms and one big one with the other room

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!

I did not think this was going to be as good as it turned out! The air quality in my house is GREAT! Just set it on AUTO and it cleans the air as needed. I even noticed better sleep and not waking up in the morning all stuffed up. This is a great unit, I purchased one for up stairs and down stairs. VERY IMPRESSED!

[This review was collected as part of a promotion.] Just the fact that this filter doesn't need replacing for five years, is an absolute win! Both the unit and filter are large in size but so is its range of fourteen hundred square feet. This air purifier couldn't have come at a better time as our air quality levels in Michigan have literally been in hazardous range on and off all summer. It also helps keep all the dog hair out of the air, and off of the furniture with its suction and two pull out screens to keep it away from the filter! I am a huge fan of the lock feature, making sure once I have it set, my little one doesn't change anything! I can smell the difference in my home, it has the same odor neutralizer in it that my Shark vacuum does, and I love it in both products. Nothing makes a mom feel better than her little one going to sleep soundly, breathing in the freshest air possible!

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.

[This review was collected as part of a promotion.] This air purifier is extremely quiet. We have a 3,500 sq Ft home and this air purifier does the trick for the first and second floor. This purifier also allows us to have the windows open and in our experience, minimizes allergy symptoms due to the fresh air. We notified an immediate positive difference in how our home smelled after using this machine for a night. Set up is super easy, just unpack it from the box, put it in the corner and plug it in and the machine does the work!

Sadly I can smell my neighbors cigarette smoke in my apartment so I bought this purifier. This piece of junk is NOT doing ANYTHING to get rid of the smell. I am returning this piece to crap and buying an IQAir. Just like everything you get what you pay for. First and last Shark I will ever purchase.
