Shark Air Purifier with NeverChange Air Filter Technology, 5 Year HEPA Filter, Covers 1400 Sq. ft, Odor Neutralizer and Clean Sense Technology, Removes 99.98% of Dust & Allergens, HP302 (Renewed)

The title says it all! I've been through 4 other air filters and all have NOT lived up to their claims. Im a smoker but my wife is not and she has mild issues with her sinuses. I've designed and installed a air system that removes the air in the room and blows it into the attic. But the vents are in the ceiling so we still need a good filter system down low. I had been looking at the SHARK unit for few weeks and decided to take a chance. After I hooked it up and went through the quick and easy instructions I turned it on the AUTO function and let it do it's thing. My wife returned home from work and asked if I had been outside all day. I said no and that I had been inside, and asked her "Why"? She said that she didn't smell any cigarettes or stale smoke smell. This filter is definitely worth the money! It does a great job removing fine dust particles and it's very quiet. It's amazing how good it works compared to the size. It's small for a entire house filter. It picks up kitchen odors 3 rooms away. And cleaning the pre filters is super easy and makes the main filter last much longer. Dollar for dollar, this filter is probably the best unit I've had the experience of using. And it saves you money because you don't have to buy a new filter every 3 months.

Solid performance, quiet in operation. Large enough to handle serious air volume. With one week of use, there is a noticeable difference in the amount of dust and the air just smells clean! Very satisfied

This air purifier is actually great conpared to my old one. My house is older and my heat/ac puts out a lot of dust, even after having the ducts cleaned. This unit lets you choose the level of speed the fan runs, tells you how clean your air currently is, clears the air for large spaces, and I havent had to replace a filter...yet. Set-up was quick and easy (be sure to take the plastic off the filter before using!), and has built in light adjustment in case you need it. Only drawback that I have seen is that it doesnt have a remote control, but I can breathe easy walking around the house. Got my on special, so I feel this was money well spent.

I will preface this with we are a family that prefers to buy used/refurbished items so this was specifically what we were looking for. This works perfectly, you wouldn’t even know that it was refurbished! I work for a family that owns a smaller version of this air purifier so I was able to get used to how they work through that. My husband has never experienced this specific shark air purifier, but he was able to figure out within seconds without the help of the instruction manual, it’s that user friendly! I have MCAS so making sure we have clean air for my flare ups as well as my husband’s allergies was essential for us and it does that well! The highest setting is quieter than a fan, but still have some noise to it, but the lowest setting is so quiet I forget it’s even running, it’s THAT quiet! It is a lot bigger than i expected, yet when we set it up in the area we wanted it, it doesn’t actually take up that much space, although i believe if set in a small bedroom it can take up too much space so keep that in mind. Our cat uses wet food and unfortunately it doesn’t help with the smell entirely, but it does significantly minimize the smell! If we ever needed a second one or know of anyone in the market for an air purifier we will definitely be recommending this one, especially since the quality of the product for this reduced price is unbeatable! (Used our Norwegian forest cat to help show how large this purifier is)

After a couple of weeks 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. Here’s my in-depth review.Performance – Impressive Air Cleaning PowerOne 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 SubscriptionsOne 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 TweaksWhile 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 BulkyThis 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 DrawbacksOverall, 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.

Works great. On auto setting, it detects when the air needs filtering, then it goes to work. The oder-neutralizer cartridge has very little order as it neutralizes the orders. We are very pleased with the Shark 1400 sq ft air purifier.
