Shark - Clean Sense Air Purifier MAX (HP232)

Would the specs you just listed apply to the Shark Neverchange available at Costco? Because I just got that one, although it advertises 1500 sq ft for 1 change per hour. I can’t figure out what the CADR ratings are for it. I’m considering returning it. Wish the Winix C909 was in stock at Costco. Would be curious to hear your thoughts on a replacement that would cover an area similar to what the Shark should actually cover. Would the Winix 5520 on Amazon be a good choice? It’s actually heavily discounted right now.

I have a little round Levoit, a Shark from Costco, an Air Doctor and now a few Alens. The Alens were supposed to be an upgrade but the model I chose has no auto button and seems to have no dim mode. The Air Doctor has both but the filters are STUPID expensive. The Levoit has both, I bought it offbrand filters and can't tell. The Shark has auto. But Shark changes everything every few years so I can't count on getting their filters again. All of them seem to do a perfectly fine job keeping my pet-filled air clean.

I have a few Shark brand HEPA air purifiers I got at Costco. They're a little pricey, but they work great, they're quiet, and they have a built-in air quality monitor for PM 2.5, 5, and 10. If you don't have that kind of money, you can make those DIY air filters with a box fan and a MERV-13 air filter made for furnaces. If you don't use something like this, yeah its likely your indoor air quality isn't much better than the outside. I think people greatly take for granted the influence of air quality on their health.

I can't believe I see people jogging on the side of busy roads on days where the AQI exceeds 200, but I see it all the time.

I got a great Black Friday deal on the Shark Max last year. No apps and filters seem to be available through Shark and third parties easily. Yet to see how long it will last but I don’t do see any issues.

I bought a Coway Airmega 200M about a year ago because it’s been Wirecutter’s number one pick for years. I have one cat and two dogs and I popped the cover off and clean the pre-screen. It tells me enough to know that it’s doing something amazing. I vacuum daily because I am horrified by potential animal smell, and the debris and dust. I decided I needed another for the back portion of the house and I got a shark air max which should theoretically cover a lot more area . I adore shark vacuums because they do well by my long coat dogs. Fast-forward two weeks, I returned the shark and got another Coway. If you have pets, that washable pre-filter is invaluable.

I bought the Shark Hepa Max couple weeks ago for the same price. It works good but i returned it and bought the Dyson TP07. I got it for $335 brand new. Go to Dyson's website and sign up for their news letter and text message and you'll receive a 10% off code. It works on sale products.

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.
