    It really does take the odor out. Seems like it does also remove dust aka allergens.

    Fantastic service. Microsoft Expert Erin Morgan assisted us in the selection of a All In One printer. Her knowledge of the products was admirable and very helpful. She was very pleasant, patient and a joy to work with. Got what we needed for a reasonable price. Thank you.

    EXPENSIVE GARBAGE

    The Air purifier worked for one day, then it showed 100% clean air for days. Finally, I read the reviews and tested the Air Purifier. A smelly, stinky dog blanket was aired out in front and behind the Air Purifier. I smelled it, my husband smelled it, and I could see the dog's hair flying. The air purifier insisted the air is 100% clean. It's expensive garbage. I can't return it, but I will draw the warranty on this one.

    We really depend on this gadget! We get a lot of Sahara dust at moments, that pollute the air badly, and as soon as our shark begins to work, you can see the pollution fall under its control

    This is a overpriced gimmick. Does it pull dust out of the air? Sure it does. Does it actually detect poor quality air? No it does not. Ive had it in my mancave which stays dusty due to no return air vent. Once hooked up it said 100% clean air. Ok I'll give it time. I ran it on full strength for 2 days straight and no difference. Ok lets give it another test. I put it in another room. Same results. So 1 more test. I put it in the garage next to the dusty drier. Guess what? It never changed off of 100% clean air. This is going back. I already have a air filter that was have the price to pull dust out of the air.

    Quiet air purifier with air quality detection.

    Excellent air purifier from Shark! It’s whisper quiet at low speed and about as loud as a PC fan at high speed. The design is simple and modern, with a bright white finish offset with a black electronic control panel and digital display. The round display at the front of the unit is clear to read from across the room and I really like how the readout color changes depending on the air quality. However, my favorite part is the Clean Sense IQ air quality sensor. It actively monitors and filters air particles as small as 2.5 and 10 microns, which means it’s not only great for dust, but finer airborne compounds too. For perspective, human hair is about 30 microns thick, so we’re talking microscopic! Great for anyone dealing with pollen or pet dander issues, or for anyone just looking to breathe in higher quality air. What’s also convenient about the Air Purifier 4 is the Auto mode which adjusts the fan speed based on the air quality. When I had it in my living room, it always jumped to high speed when I was cooking and I could see the air quality drop to the 50% range. Then it gradually lowers the fan speed as the air gets cleaner and settles at low when it’s back to 100%. And while there’s 3 manual fan speed settings, I just leave it on Auto and get on with my life. The sensor seems to do well enough and I notice it’s not back to 100% until most of the smell of what I was cooking is gone. Shark did a great job making it quiet too, with 4 micro fans constantly working to suck and push air. It really is whisper quiet at low speed, making it practical for the bedroom if you’re a light sleeper. It’s funny, it’s replacing an old air purifier that’s 4x smaller, but louder at low speed than this one is at high! The remote is a nice touch too. I pretty much never use it, because I leave it in Auto mode, but it has good tactile feedback and distance. I’m surprised there isn’t a UV light for an air purifier in this class and price range, but the anti-allergen HEPA filter should do a good job of scrubbing out the bad stuff. It’s rated to filter down to 0.3 microns and comes with some kind of odor lock to trap in the smells. I know it works well for cooking smells and smoke. There’s also a sensor that tells you when the filter’s dirty and needs to be changed, which is convenient for when the time comes. My only gripe is that the air intake is in the rear, so I can’t place the purifier flush up against the wall. Or I could by turning it around, but then I wouldn’t see the front digital display. This is a small and personal inconvenience though, as I’m much happier with the quiet fan speed and automatic air sensor over the much louder one it’s replacing. Overall, this is an excellent air purifier for medium sized rooms and is especially great as a bedroom air purifier for light sleepers. It’s modern looking, quiet, has an anti-allergen HEPA filter that filters down to 0.3 microns, has 2.5 and 10 micron particulate sensors, and an Auto mode that lets you set and forget it. If you’re in the market for cleaner air and/or have allergy issues, I highly recommend giving the Shark Air Purifier 4 a look.

    Cleans the air well but conpared to other filters on the market. This is more expensive and less efficient. I went with a 5 year filter ultimately.

    I have a lot of pets which is why I bought it and it’s worked so great! I used to have pet hair just flying around and this helped control that and now i hardly see any hair flying around.

    Used in a space that’s about 500 sq ft which is only half the coverage area up to which this product is meant to cover and doesn’t seem to do the trick. My floors and other surfaces still get super dusty all around, and I’m not sure if this machine has done anything to improve it.

    This air purifier is one of the best that I’ve tried. It responds to changes in air quality fast, and efficiently cleans until air is pure again. Would recommend.
