I have cats and food odors to contend with. This is no longer true with the air purifier which silently reassures as to air quality and very gently (lowest setting) infuses a gentle replacement scent into the air. I am thoroughly satisfied.

Alleviated my allergy to a shedding Aussi within a matter of a few days. Stopped sneezing - 12 to 15 2 or 3 times a day. Now, 2 or 3 individual sneezes in two weeks.

I bought this air purifier because I was tired of the plug ins and candles with the overly sweet and floral scents. Now my home smells fresh and clean.

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.

In a world of so many air purifier choices we simply need something that works. We trust the Shark Ninja name and Sam's for quality. We can tell the positive difference this air purifier is making in our home that we share with cats.

Broke after 5 days, making a horrendous squealing noise whenever running. Called for support and they couldn't replace it for a few weeks, called back and they still cannot replace it. I'll be honest I'm getting pretty mad at the whole ordeal.

I've used the Shark NeverChange for 4 months now after doing much research into what could reduce my allergies, the Shark NeverChange was recommended several times over and the bonus that the filters don't need changed often was a strong selling point. The purifier is so easy to use, with simple controls on the top of the device, I like how you can turn the display brightness down, or completely off if you choose. There is a handy feature that shows how many particles of different sizes are being collected at any one time. Overall my impressions from short use have been fantastic, the air feels cleaner in the home and my allergies have significantly reduced, the device is easy to use and despite being large it is easily moved to another location because of how light it is. I look forward to continuing to use the Shark NeverChange.

To be honest, I already knew this thing worked. I'd seen the air quality reading drop every time I lit a candle and turned on the purifier, or even after using my "healthy" air fryer. 😅 But today really surprised me. With the wildfire smoke from Canada reaching Chicago, I got home from work and opened my front door for just a few seconds... and my purifier kicked on almost instantly. The air quality reading dropped right away. I was honestly amazed. I'm so thankful to have one of these at home. It gives me so much peace of mind knowing I'm breathing cleaner air, and my chronic allergies have gotten so much better too. Just to be clear—this isn't a paid promotion. I bought it with my own money because I genuinely love it, and having it in my home has honestly been such a blessing. 🤍

This is the second I have received. The first purchase didn't work properly, you sent a replacement that also doesn't work just like tge first. Looks like now you're trying to trick me into buying another? A newer version? I want what I already purchased yo work properly, is that too much to ask?

My family has been using the Shark Never Change for a little over a year now and it has definitely been a life changer in my kitchen and living area. It covers 1,400 sq ft and my kitchen space and living space are close together so it pretty much covers our area for we don't have quite an open concept. Let me tell you how many times I have cooked steaks and fried fish that happen to have strong smells, tracks it down quickly. I'll see the number percentage drop and as it does its job to filtrate the air, the numbers rise up quickly and I mean within minutes while I cook. The little screen shown in the front where the numbers pop up, the lighting is perfect and always on even at the top adjustment. You can adjust the power to how fast you want the fan to go. With that being said, it comes with an odor neutralizer leaving your space area smelling fresh and clean. The odor neutralizer is good for 6 months so it's nice to not constantly change it every month or so. As for allergens, it collects in large particles such as airborne pollutants, dust, pet dander, pollen, smoke, bacteria, and micro sized particles. And what makes this air purifier different is that it prevents any buildup on its HEPA filter making it easily to remove the screens which you can either vacuum or wipe down, even rise if you prefer that.
