I have awful allergies and have at least four sneezing attacks (more than 15 at a time) a day, normally. I also have four dogs. When I remember to run this machine, I do not smell dog odor in my house, nor do I have huge sneezing attacks! My husband commented when he came in from work that he couldn't smell the dogs. My daughter's boyfriend cooks really smelly food that usually makes the house stink the next day. My Shark revs up and destroys the odors within minutes of him being done. My husband has requested that I do not run it while making bacon, because he enjoys that smell and the Shark eliminates it as well. I highly recommend it if you have allergies or live with animals and/or smelly people.

Having our home on the market to sell and being told our house smelled “doggy” due to our two Boxers, we realized something had to be done. I purchased this air purifier with high hopes and I am VERY happy to say it has not disappointed us yet. It has most definitely done away with the “doggy smell”. The next best thing is that is has helped cut down on the dust in our house too. That’s what I call a WIN/WIN!

I've only had this air purifier for about a month, but so far, I love it. It gives you a percentage of how clean the air is and that lets you know when you need to clean the side screens. Just rinse in water, let dry and replace. Hoping the filter lasts the 5 years or so that it says it should. Saves a ton of money in filter replacement.

The shark air purifier works great. Very quiet. When I’m frying something in the kitchen, the air purifier kicks higher to purify the air in the house. The only thing that I am displeased with is the FedEx driver who was too lazy when he delivered my air purifier, he put it in the middle of the driveway instead of walking to my front porch, putting it under shelter and out of sight in front of my doorbell camera.

This has really improved the air quality in my space. I know several people have said that it doesn't work because of the initial reading of 100% but i found that after running it on auto for 24 hours, it began getting more accurate readings. I am very happy with this purchase and would recommend it to friends and family.

Big improvement in our air quality at home. Not perfect, but vast improvement. I’m 70 and this is our first air purifier. It’s a Shark, and advertised as a “NeverChange” filter, but ours was down to 94% efficiency after the first week - however we live in El Paso and the air quality here has been the worst in America for several weeks…the CEILING of the danger zone (500). Yes, I would buy this unit again. Also, Sam’s was offering a $50 discount, which helped a lot.

Love this. When i bought i had 3 dogs. In 1 month i cleaned the exterior screen filters 1 time the air Quality it much better in my home and i feel it doe the entire house as a smoker lived here before us and upstairs would snell smoky on hot days this is no longer an issue and i keep the air purifier on the main level

The machine works fine, it's the added air freshener that I despise since it was encouraging allergy reactions despite my first turning it down and then completely off. Finally I just threw the dang thing away. It doesn't smell like an ocean breeze in any sense of the word and I've been to both oceans and the Gulf. It smells like cheap perfume which I'm also allergic to. Had to call customer support the first day to figure out the dang air freshener is in the sealed pack and the entire thing pops in the top. The machine did quite working on the third day. We run it 24/7 and one morning woke up and it had stopped. Called customer support who are great by the way thus the 4 stars and discovered one of the sides had popped out, easy fix and it has had no other issues.

Love this air purifier. I am allergic to cats and have 2 living in my house, thank goodness its not a severe alleegy but constant exposure is not good this purifier helps.

Very quiet , decent scent feature but the scent does not last long , very nice auto setting feature that increases filter fan when poor air quality detected
