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 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.

I've had 2 Levoit air purifiers and recently bought the new Shark Ninja one that doesn't require filters. They are all awesome at helping me breathe and keeps the dust and cat hair under control.

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
