Shark - HP150UK

He will get used to them. My boyfriend has pretty bad allergies too and the more he is around an animal, the easier it is to deal with. His body grew desensitized to his old roommate’s two cats. Air purifiers also work. I’ve got a little shark one that makes it much easier for my boyfriend to spend the night, and the cats will even crawl all over him.

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/)**.**

Please read the AutoModerator comment. Air purifiers aren't good at reducing *visible* dust as it's larger and heavier than "invisible" pollutants like PM10 and PM2.5. The same goes for pet hair. Sans is terrible. Shark is mediocre. Avoid both. Coway is generally one of the highest quality consumer-grade brands. Winix is good, more mid-grade. Blueair has an always-on ionizer. Some people want to avoid this because of possible health effects associated with ionizers or changes in gaseous air chemistry. Per the AHAM 2/3 rule, a space 600-800 sq. ft. needs minimum Clean Air Delivery Rates (CADRs) of 400 CFM - 534 CFM. Unfortunately your budget doesn't support a single large or multiple conventional HEPA purifiers. (An example that meets CADRs would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox).) If you still want a conventional HEPA purifier, go with the [Winix C909 at Costco](https://www.costco.com/p/-/winix-c909-4-stage-air-purifier-with-wi-fi-plasmawave-technology/100842491). It's a bit of an energy hog (95 W) and somewhat loud on the highest setting called "Turbo" (60 dBA per the Decibel X Android app), but it's good value for money. The C909 has PlasmaWave, a bipolar ionizer. You may want to keep this off if you have pet birds. Another option may be the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro). It uses Efficient Particulate Air (EPA) E11 filters, which is two filter classes below HEPA H13. Top composite CADR is 413 for the CARB Edition. Price is $159.99. Keep in mind CADRs listed by purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning effectiveness.

I think I'm parsing your comment here correctly, but... don't buy Shark. It's a lousy brand with very misleading marketing—e.g., "NeverChange" filters. They don't publish Clean Air Delivery Rates (needed to size a purifier for wildfire smoke particulates). It also has a tiny amount of activated carbon so it's useless for VOCs or other gases. We've seen multiple issues with Shark's air quality display malfunctioning on r/AirPurifiers. You need many pounds of activated carbon or other sorbent media for wildfire smoke gases, VOCs, or odors. And even then, plain/non-chemically treated activated carbon doesn't have high removal efficiencies for all gaseous species.

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 two Shark ones too, I'm happy with them. One is also near my cat's litter box, mainly because I'm super paranoid about my house smelling for guests. I've visited too many homes over the years that look clean, but are definitely smelly. I know when you're the one living there, you don't even notice it. Just a recommendation as a fellow cat owner though, I switched to pine pellets a year and a half ago and there is almost NO smell from the litter box, it really absorbs the urine. Added bonus there's no dust like with clay ones (I don't trust the even the ones that claim they are "dust free". I use this brand: https://www.petco.com/shop/en/petcostore/product/feline-pine-cat-litter?srsltid=AfmBOorIHcL_YhTcQId9bj7qgmBmG-vFBd88---gl8sP_gKCQjoiPhx_ A 40 pound bag lasts me around 3.5 months with one cat.

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 got a shark one and I’m still not converted if they work .

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.

Shark air purifiers work pretty well
