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

Winix was the other brand I saw at the store and it was definitely cheaper than Shark. I only went with Shark because I knew of the brand already and did next to no research.

Another edit because I can’t respond to everyone since I’m on mobile. I already bought it, brought it home, and plugged it in. I plan on using it for a bit to see if I notice a difference. It’s the Shark NeverChange Max. There was another brand at Costco (Winix?) that was cheaper but like I said, I did practically no research and went with Shark because I knew the brand. The tiny research I did on my phone in the store said I should be able to not have to change the filter for a few years, which is a huge plus to me. I’m finally looking more into reviews of this particular model and they’re overwhelmingly good, so that makes me happy. I guess we’ll see how it works going forward.

Definitely! It said it works well up to 1400 sq ft which is bigger than our entire house, lol. I have it in our living room/play room where we spend most of our time.

No because I did practically no research. Since I already brought this one home, we are going to try it out and see how well it works.

I got shark neverchange last year on sale after doing a ton of research on if they actually help. I had been suffering with a stuffy nose at home for a few years after moving into an apartment that had poorly sealed windows and having a wildfire season that made the air really bad. After getting one, my stuffy nose has cleared up, and it's easier to breathe at home now. I dont think super cheap ones will work well, and you dont need to buy a really expensive one. But they are worth it and, in my opinion, really do help.

The version i have is the Neverchange Max. It does come with a scent packet with a dial to turn it up or down. I have that turned to medium most of the time as well and have not noticed any effect on my cat. It may be different for other cats with the scent. Good luck with the new fan!

I'm currently debating keeping it or returning to Costco. CONS: the scent pods are horrendous! I don't like anything scented, so don't plug them in. It's an option. Not sure about the 100% clean air being actually 100%. As someone else said: you can run it on low 24/7 PROS: it does kick in on auto setting when cooking, so the sensor works! Cooking odors seem to be neutralized after a while. The multi-stage filtration seems like a good idea, we will see how long the filter **really** lasts? The fan is strong on max (also loud) I'm having mixed feelings, not sure it's worth the $230 (with coupon) but worst case could keep it as a fan (albeit overpriced)

Joining for comments. I'm trying to decide whether to keep it or return it to Costco. It seems to be working to some degree, but don't have pro tools to measure the actual particles. Worst case I'll keep it as a (expensive) fan? At $230 it's not a terrible price for "never" changing a filter. Sitting in the kitchen on auto it kicks is immediately when cooking, so it's doing something.

I grabbed the Shark NeverChange MAX off Costco a few months back and honestly, it's grown on me.

I have 2 Coways and tried a Shark. I kept the Shark moved the Coways to less prominent rooms. The Shark performs better at detecting lower air quality sooner and has another fan speed level, so it doesn't get as loud all the time. I prefer the Shark and bought a second with larger capacity and it's even better. Shark NeverChange Air Purifier MAX

I have one and am happy so far - and to contradict misleading statements posted here - you can set a fan speed and have it run 24/7. The default automatic mode will shut off the fan if the sensor deems air quality is good I run mine 24/7 with the intent of perhaps replacing the filter every 2 years but will monitor - it definitely will NOT last 5 years if you run the fan continuously (read the fine print). Also every time I cook in my condo it air quality sensor detects the degradation of air quality and display values reflecting the air quality change so I believe the sensor is reliable. Also it can circulate a lot of air quickly and I ramp up the fan speed sometimes just for the cooling effect without the need to run my AC as often.

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.

No. For several reasons: 1. Never change is a lie, you’ll be lucky to get a year from the filter. 2. It comes with SCENT PACKETS. Air purifiers remove contamination from the air, they don’t add things to it! 3. Like all things Shark, it’s disposable.

Not worth it at all, tried it for a week and returned. The “auto” mode turns off the fan entirely because the sensor claims the air is 100% clean which defeats the entire point of an air purifier. Also uses sent pods which just add VOCs to the air. Got the Winix 5520 from Amazon on sale for $150 and night and day better. Fully automated but air is always moving even on sleep mode. Also quicks up to higher speeds quickly when cooking or my dog farts while walking by lol.

I really like my Shark never change filters. They’re really quiet and pick up on air quality changes super quick. Easy clean

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. 

I can't comment on the Levoit. I did recently purchase the shark never change air purifier. It has a HEPA filter and does not produce ozone. I live in a small apartment and it has improved the air quality. The one I purchased purifies 650 sqft., it was $179 on Amazon. I would recommend this air purifier based on my experience.

I've read mixed reviews about it. I took the chance and am pleased with my purchase.

We have 3 Levoit, but I got a Shark "never change" and I'd recommend it. You can turn all the lights off for sleeping and you don't need to replace the filter but every 5 years I think? It also has several modes and shows the percentage the air is clean. It'll kick on when needed

Shark Never change Air Purifier is great

I have the Shark NeverChange, and it is worth every dime. As advertised, and is very sensitive to the least obvious air quality issues. Cooking smells, body odors, even cleans the air after a candle burns but keeps the essence of the scent. Cant speak to the one you are speaking of, but that Shark is the real deal

You don't need HEPA for dust and dander, Merv 13 will handle it. I bought a Shark NeverChange on sale for my living room because it's the largest room and my forced air doesn't push enough through to filter for our 3 dogs and 4 cats. Supposed to be 5 year filters (we'll see) and it has a built in AQI sensor. It also senses if the pre-filter is clogged and tells you to clean it and they're the most easily accessible I've seen.

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 bought one. Not so sure it works. The light ring that indicates a change in air quality does change when I cook. I’m in an apartment. The unit is in my living room. But it takes a good 40 min to an hour to get back to 100 %. I would think that’s just the natural time of the air clearing. No help from the unit. 🤷🏻‍♀️ Also I just put it in the bathroom w my bf while he poops. No change in the air reading or smell of the bathroom. After this test I am returning.

I have one and I love it! I have two sick people in my house with a cold. It’s been kicking on a lot lately because it detects bacteria and viruses in the air. 🦠

I just bought a Shark air purifier and it’s near the kitchen. No more food smells lingering in the kitchen. It does NOT like sauerkraut, burnt eggs or fried tortillas 😆

Clears the air way faster and better than my Dyson. It’s a workhorse.

there are 2 filter, it has pre-filters on the outside that can be washed and inside is a typical air filter cartridge. The idea is the outer pre-filters catch most the debris and can be washed off, saving the inner hepa. But no, it’s not actually never-change, you will eventually have to replace the hepa, I think they say 5 yrs but all depends on

I have this model. It advertises as lasting 5 years between changes, but I think that is inaccurate because each environment is different. I think mine will need yearly or bi-yearly changes.

We've had ours for a few months. We keep it on auto, and don't use the fragrance thing. The purifier kicks on when we are cooking. It's nice and quiet.

I have one and love it. I keep it running constantly. Every now and then it will turn itself off and I have to spray off the filters on the sides and then it goes right back to work. I have 2 dogs and there’s a noticeable improvement in pet smell. I’m not sure where to get replacement air fresheners for it though. I definitely recommend one of these, especially if it’s discounted

Good for cigar smoke.

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

Just bought the Shark from Costco last night. My anecdotal evidence so far: My college age son has allergies and always wakes up feeling crappy, he said he actually felt good this morning. I let the dogs out this morning and left the patio door open the air quality monitor dropped significantly and the air purifier kicked into high. My husband and I went to bed with sore throats last night after running errands, no sore throats this morning. As someone who is affected the bad air quality I’m getting desperate.

We have 2: one downstairs and one upstairs. They work very well. Only have to change the filters every 5 years.

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).

Mine stopped working after 2 months. Sensors read poor air quality all the time so the unit was running non stop. Luckily I bought it from costco so return was easy.

I have shark, love them!! I smoke weed but honestly don’t smell it when I get home anymore 😜

Shark

Had it for a few months, takes some of the dog smell away… seems to be working well

Buy the shark. The Winix ones die so fast.

I bought ours during Canadian wildfires recently. Have 3 cats. I think it helps, esp with cooking related stuff.

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

We have a Shark that we got on sale and I like it because it also gives a reading of what the air quality is in the room. But we also have a “levoit” small one from Amazon that we put in a small room, and we’re used the reader on the Shark to see if it works and it works just as well.

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.

I tried it and returned it. I wanted to use its auto mode. But it doesn't seem to ever turn on by itself. Since that's the primary reason I wanted that model, it just didn't work out.

I suspect that's part of their marketing for the Never Change filter, by using the auto mode.
