Shark - NeverChange Air Purifier, 5-Year Filter Life, 650-sq Ft - Black HP152

I have bought a lot of different air purifiers over the last decade. This one is my favorite for many reasons but mainly because you don’t have to constantly buy new filters. Doesn’t have to be these exactly but something like this. https://www.bestbuy.com/site/shark-neverchange-air-purifier-5-year-filter-life-650-sq-ft-black/6567890.p?skuId=6567890 Or https://www.bestbuy.com/site/shark-neverchange-air-purifier-max-5-year-filter-life-1400-sq-ft-white/6548655.p?skuId=6548655#tabbed-customerreviews

Shark is a rather poor brand. "NeverChange" with "up to 5 years use" is purely a marketing gimmick. [The owner's manual for the HP150 series](https://support.sharkclean.com/hc/en-us/article_attachments/13082454422044) states this is "based on 50% CADR declined, 135 sq. ft. cleaning area and 12 hours daily operation on MAX fan speed." [The infographic on the model HP152 product page](https://www.sharkclean.com/products/shark-neverchange-air-purifier-zidHP152) is different, claiming the cleaning area is "300 sq. ft.". Don't know which one is correct. Either way, that's much smaller than the 650 sq. ft. rating. And obviously any mechanical filter's lifespan depends on pollutant concentrations. Yes, many consumer-grade air purifiers have air quality sensors. Nearly all of them are junk as they are cheap and therefore inaccurate. We've had multiple posts about Shark purifiers and their wonky air quality sensors. See: [first post](https://www.reddit.com/r/AirPurifiers/comments/xmek6u/new_shark_air_purifier_6_displays_100_air_quality/), [second post](https://www.reddit.com/r/AirPurifiers/comments/1fhrglr/shark_air_purifier_stuck_on_0_clean_air_broken/), [third post](https://www.reddit.com/r/AirPurifiers/comments/1abxndq/shark_cleansense_always_reading_100/), [fourth post](https://www.reddit.com/r/AirPurifiers/comments/1b95ikg/shark_never_change_always_100/), and [so on](https://www.reddit.com/r/AirPurifiers/comments/1hobihz/shark_clean_sense_iq_never_improves_air/). The "Odor Neutralizer" (where included) emits a "fresh scent". This just worsens air quality, as the scent is comprised of VOCs. The standard carbon filters for the Vornado AC350 model will contain next to no activated carbon; it's a plastic base coated with activated carbon powder. Even low to moderate levels of VOCs or other gases will not be adequately removed over time. I doubt the upgrade is significant either. **For particulates, the primary metric should be Clean Air Delivery Rates (CADRs) following the 2/3 of your room's area** [AHAM rule](https://ahamverifide.org/ahams-air-filtration-standards/)**.**

I have a Shark NeverChange MAX and it does a great job while not needing the filters to be replaced for a while. I have family with cat allergies and it does a good job making it manageable. The odor capsules are also pretty helpful especially if you're a member of /r/trees

Same! Felt my allergies starting to kick up again and for some reason, it's always worse in our bedroom and at night and my shark purifier verified it. But more importantly, since I have had it running, my allergy attack subsided way way faster than it normally does. 

Just got the shark never change and it's pretty quiet even on its highest setting (like a low fan). It's only on the highest setting when air quality isn't the best. If I keep it running all day and night, it's usually whisper quiet at night since it already cleaned the air during the day. 

Had the same question and finally bought the Shark never change filter. Very happy. I watched a lot of comparison videos and let chat gbt look at the specs of many models at many price ranges. When I brought it home and it said my home air quality was 98% when I turned it on I was disappointed, however, the first time I cooked and I chocked on the air quality while watching the meter go down to 67 then back up to 100 over the next 25 minutes my doubts were gone and I wouldn’t go back or choose a different one.

Shark Never change Air Purifier is great

I bought 2 Shark Never Change air purifiers through Costco. They were a better deal than the actual Shark website. They are great. So quiet. They are on auto and monitor the air and adjust accordingly. Super easy maintenance, as the HEPA filters don't have to be changed and the dust filters take seconds to wipe and re-install.

Depends on what your expectations are. The Shark Neverchange is fine as far as purifiers go, people on this sub are obsessed with Coway and Winix so you won’t get many other suggestions outside of that. Air purifiers are essentially a fan with a filter, the neverchange has pre filters to protect the hepa filter. The hepa filter in that machine also has an included “pre filter” wrapped around the actual hepa filter. The filter will undoubtedly last longer than one without or with partial “pre filters”, just maybe not 5 years. For the space you’re looking to cover I’d recommend 2 purifiers or using the neverchange on med-high permanently (avoid auto).

We own two of the shark never change and we are so happy with them. Highly recommend. If you want to test the air filter, cook something near it. When we cook bacon, the display drops down significantly

We have a purifier on every level of the house, 3 in total. They are definitely game changers and help with smell, but also dust. We have two shark air purifiers with hepa filters, looks like it’s 120$ right now online. (So you can possibly get two depending how your house is set up) Those two are on our downstairs level one in the basement where the box is and one on the main level. They’re very quiet I never hear them, run them 24/7 with no issues. Our third is a dyson, honestly it was a gift i wouldn’t spend money on it 🤣 id stick with the sharks lol

I have a Dyson - it was a gift, and honestly I wouldn’t buy one myself 🤣 I honestly don’t even know if it does anything it’s on in our bedroom. We have two other purifiers one on each floor and they’re sharks, they were about 100$ each. Work great and the one in the basement really keeps the kitty litter smell to 0.

I’ve been running a Shark air purifier for about 3 months with no noticeable reduction in dust

I bought a shark air purifier a few years ago and it was always at 100% I had to get a replacement and it actually worked.

I have a Shark one in my kitchen and do love it, but only bought it because of our lack of extractor fan and the fact I became a bit intolerant to my cats when I got pregnant. I probably wouldn’t want to spend the money on one unless, like you said, there is a specific issue you need to tackle. A dehumidifier on the other hand - we’ve noticed the air quality rating on the purifier improve drastically since we bought the dehumidifier. The house warms easier and, obviously, there is less moisture and condensation in the house so we worry a lot less about mold and damp in the colder air (especially being close to the coast in the UK).

Shark

Buy the shark. The Winix ones die so fast.

I like my Shark Air Purifier. The filters are reusable and easy to clean, and the unit itself is affordable.

There are lots of fraudulent bad air purifiers which are nothing but expensive fans out there. I have asthma, and have 3-4 purifiers of various different stripes throughout my home. Some are indeed better than others. Because i have asthma, I make sure that air purifiers do not have ionizers (which emit ozone and cause respiratory irritation). I use germ guardian, honeywell and shark. Depending on the size of the room, I try to get ones that fit the area in question. The current one I like is: # Honeywell AllergenPlus HEPA Air Purifier, Airborne Allergen Reducer for Large Rooms, Reduces Allergens, Smoke, Wildfire Smoke, Pollen, Pet Dander and More, Black, HPA200

We have a shark that filters very well. I'll hit my bong and watch the air quality go to 0%. That's when I know I'm really getting clean air.

I have had Levoit purifiers and 1 Shark throughout my house, so a total of 9, which range in all sizes. 7 of them have sensors built in, which change the color based on air quality. I also have a couple other sensors one being a Kaiterra Egg the other two being handheld air quality testers from Amazon. I’ve found the readings between them to be very consistent and accurate.

Don’t get the shark.

Sorry. To expand - don’t get the Shark, it’s poorly built and they’re lying about never changing the filters.
