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

The cost/poor quality of our old cleaners made the decision to buy the Shark NeverChange EZ! The Shark NeverChange does such a great job we could easily tell a difference within 24 hours of plugging it in! Thank you Shark

I have never had an air purifier before. I was hoping it might help with allergies, dust particles and lingering odors from cooking, etc. well, it does ALL of that! 110% pleased with this purchase. It is extremely quiet on the 2 lower speeds, you don’t even know it’s on. I love it. Great purchase.

It is amazing, it cleans the air up wonderfully. I plugged it in late afternoon. Let it running on high during the early hours of the morning. Around 2:00 I got up and put it on auto and stay’s on 100% unless I cook bacon or onions stuff like that. Then after it takes about 15 minutes it cleans air up again and back to 100%. Our sinuses are so much better. We were getting over Covid when it come in. It helped with breathing. Just amazing.

Got this to improve air quality in my home- live in an urban environment and have a large, shedding dog.Super simple to set up. I only use the cartridges on low, because the scent is a bit strong for me. It's so quiet I wasn't sure it was actually doing anything, until I was cooking and it dropped into the red! I love the easy to read display. I never use the remote, I've just let it run after turning it on over a month ago. Seems to be cutting down on dust/dander. Very happy with this purchase, and that I won't be feeding it filters constantly.

Very quite & does its job! Great for when cooking because it rids your home of any newly introduced oders & leaves no lingering oders. The auto detection of the air is amazing because as soon as a smell is detected the machine gives a reading of air quality & turns on, once the air quality returns to 100% the machine returns to auto mode & continues to monitor the air quality of your home.

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.

Does what it’s made to do, clean air during winter. Use in kitchen area, works well to clear air of residual cooking smells. Is louder on high than our Alen purifier, but for what we use it, it’s perfect. Highly doubt the 5 year filter life, time will tell.

In a house with 2 dogs we thought this would be a good purchase. I don't really notice a change in the air or smells. Maybe if I left for a few days and returned. The only time we see the percentage go low is when cooking, mopping floors or burning a candle. That seems odd but so far I like it. Do not think the $300 investment was worth it, but still keeping it and running it.

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.
