After a month of using the Shark NeverChange Air Purifier Max, I'm impressed with its performance. It's a powerful unit with some standout features, but there are also a few things I wish were different. Performance – Impressive Air Cleaning Power One of the biggest reasons I chose this purifier was its ability to clean up to 1,400 sq. ft. of air per hour—and it delivers. The built-in odor neutralizer is also a great touch, helping to keep the air fresh. What really stood out to me was how well it handled smoke from my wood-burning fireplace. The moment it detected the smoke, it kicked into high gear and cleared the air without hesitation. That level of responsiveness gives me confidence that it's effectively maintaining indoor air quality. Cost Savings – A Long-Lasting Filter with No Subscriptions One huge perk of this purifier is the 5-year filter life. Unlike other brands that require frequent and costly filter replacements—or even force you into a subscription plan—this one is designed to last. That's a huge cost savings over time! Usability – Auto Mode Needs Some Tweaks While the purifier works well, I noticed a small issue with the Auto Mode. When the fan is off, it takes a lot of dirty air buildup before the unit starts up again. This means that instead of maintaining consistently clean air, the purifier waits until the air quality worsens significantly before reacting. A more proactive approach in Auto Mode would be a great improvement. Design – Functional but Bulky This is where my biggest complaint comes in. My wife jokingly says it looks like a modern-day propane tank, and honestly, I see it! While it has a futuristic look, it's a bit bulky and doesn't blend seamlessly into our home. I personally would have preferred a sleeker, more slender design that complements modern interiors better. Final Thoughts – A Solid Choice with Minor Drawbacks Overall, the Shark NeverChange Air Purifier Max is an amazing air purifier. It has great performance, efficiently cleans large spaces, and works exceptionally well at removing smoke and odors. The 5-year filter life is a game-changer, saving money compared to brands that require frequent replacements or pricey subscription plans. However, Auto Mode could be more responsive, and the design could use some refinement for a more seamless fit in modern homes. If Shark develops a sleeker, thinner, and more refined version of this product in the future, I would definitely be interested in checking it out. Despite these minor drawbacks, I love the Shark brand, and this purifier is a strong contender for anyone looking for high-powered air purification without the hassle of constant filter replacements. Would I recommend it? Yes—especially if you prioritize performance and cost savings over aesthetics.

Purchased this three weeks ago, have had it set up for a week now running, the prefilter screens on both sides are as clean as the day I turned it on the first time. My window AC unit filters more dust than this thing does. I would return it but I threw the box away, stupidly, because every Shark Vacuum I own has been amazing so I thought this should be as well. WRONG. My little dog is litter trained, when he goes to the bathroom the unit doesn't even kick on from auto to a higher speed to clean the air, 30 minutes later the air smells the same. I am going to give it a full month then if it doesn't work I will bite the bullett and buy another brand.

[This review was collected as part of a promotion.] I am impressive with the features on this air purifier. The permanent filter will save me money. Thr on board controls feels new. I love that it tells me how clean my air is. I can have it run all thr time or use the timer. Includes a little separate filter for odors. It disperses a mild scent that is pleasant. It is pretty quite too! I love it! I find myself dusting less too since running this. highly recommended!

[This review was collected as part of a promotion.] I live in Minnesota and recently the air quality got worse since there are forest fires next to the Canadian border. This Shark Air Purifier unit gives you more than an average home air purifier. It's not just high performance up to 1200 sq ft, smart technology, real HEPA filter and so on. It is a quiet, powerful and well designed unit. I recommend it for every household especially if you are sensitive to the air quality in your living space.

I bought 2! They take even the good smells out of the air! They run all the time as I have plug inns and wax melts going. I want it to leave the good smells behind! I haven't bought any other product to compare it with but definitely cannot speak ill of them. I haven't bought any dogs and in just three weeks cannot believe the difference!

If I could give this 10 stars I would. I have asthma, 2 guinea pigs, 2 dogs and a cat, I have had my share of air purifiers in my lifetime, even the really expensive ones that start with a D and end with a N, and lemme tell you this machine has been telling me I have bad clean air for a few hours as it did its thing, mind you, the room I put it in has a winix and a Dyson in it, I immediately can tell a difference in the air. I am a believer!

[This review was collected as part of a promotion.] This air purifier is extremely quiet. We have a 3,500 sq Ft home and this air purifier does the trick for the first and second floor. This purifier also allows us to have the windows open and in our experience, minimizes allergy symptoms due to the fresh air. We notified an immediate positive difference in how our home smelled after using this machine for a night. Set up is super easy, just unpack it from the box, put it in the corner and plug it in and the machine does the work!

Love it so much that I ordered another. It's super quiet and I feel like it genuinely cleans the air. I like seeing the air quality reading on it at 100%. I know it works because we have ours set up near the kitchen and anytime we cook we notice the air quality reading drop some but soon after it gets right back up to 100%

Excellent w removing smells from the air. Doesn’t remove dust and particles as advertised on box

This will keep your house odor free and so much more.
