Shark - HP150UK

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/)**.**

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).

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.
