I love how quiet this unit is and how fast it works. This is very simple to set up. We will test to see how long it really takes before filter change. When I walk in the house smells clean. The odor neutralizer is another great feature to have. Now you do not get much of that when it is on low speed but when it kicks on high speed, you get a little bit of the odor neutralizer. It has great air flow and coverage.

I cooked onions garlic and peppers with the air purifier on. Hour later still smells like I cooked my dinner. Smell is not as pronounced but for the square foot it's supposed to clean and my home is less than that. I'm kinda disappointed in shark as they have always made great products in the past. What's is happening in the manufacturing end?

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 thing really works well!! It is located in our living room which is near the kitchen. Every time we cook, you can see this thing get to work. It will drop down to around 50-60 percent air quality then boost the fan speed automatically until the quality is back at 100 percent. It fits into our decor well and isn't too noticeable. The washable pre-filters greatly extend the internal filters lifespan.

Do not fall for their "NeverChange" filter that supposedly lasts about 3-5 years. Not even close! Mine lasts about 6 months, and that is in par with most reviewers are also experiencing. The filters are expensive and in reality this Air Purifier feels more like a filter subscription that you didn't intend to sign up for. False adverstising and misleading marketing strategy.

Works pretty good. It's an air purifier not sure if it completely purifies the air or not but it's full of dog hair and dust when I clean it so it must be working. I suppose I could say I wish it would purify the air in my house 100% but that wouldn't be realistic now would it. I would buy another because it's got a pretty good size filter footprint compared to others out there.

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.

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.

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 have a couple other air purifiers in my home and this one is a new addition. Have not had it long, but so far it seems to work well--very quiet. I like the odor neutralizer packets since I have pets and that the filter may be cleaned.
