I love this product so much, it truly made our home feel and smell cozy, safe, and a healthy living environment for my family.

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.

You need one of these in your home.

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. 🤍

Love this air purifier so much! It constantly shows you the air quality in the room. It also came with a fragrance insert that smells so good! The air filter is supposed to last 5 years!

It works!

Purchased this air purifier when my 10+ year old Dyson stopped working.
The set up is easy and the display is helpful.
The air quality in my room went from 68% to 100% in 2 hours.
I plan on purchasing another one for another room.

Tremendously disappointed

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?

Not as expected
on July 13, 2026
Posted by: Sam1223
I’m disappointed with the Shark NeverChange Air Purifier. I expected it to collect much more dust, but after using it for a while, it doesn’t seem to capture nearly as much as advertised. there’s plenty of dust in my home did not feel any difference with purifier.
I’ve used a few generic air purifiers that actually seemed to do a better job at trapping dust and improving air quality. Based on my experience, this product hasn’t lived up to my expectations, especially considering the price.

From day one my allergies changed —
on July 4, 2026

I didn’t expect to notice a difference so fast, but the Shark NeverChange™ Air Purifier Max genuinely surprised me. From the first day of using it, the air in my space felt noticeably cleaner and lighter — and most importantly, my allergy symptoms improved way quicker than I anticipated.
I usually struggle with dust and seasonal irritation, especially indoors, but this has made my environment feel much more controlled and fresh. It runs quietly in the background, so it doesn’t interrupt my day or sleep, and I love that I don’t constantly have to think about maintenance or filters.
What stood out the most is consistency — it doesn’t feel like a “temporary clean air effect,” but more like a stable improvement in the room’s overall air quality.
If you deal with allergies or just want a noticeably fresher home environment, this one feels like a real upgrade rather than just another gadget
I would recommend this to a friend!

I ve been using it for several months now. It covers much more area than advertised. Efficient. Very quiet . Also the odor removing cartridge very useful and smart design. I use it as needed. Love the fact that filter goes up to 5 years.
I would recommend this to a friend!
