"Noise on the 3i is next to zero."
"another plus for Alen is that they are insanely quiet. I have a 45i and 75i and they are excellent."

"The previous tenant had cats and there was SO much cat dander even after hiring deep cleaners TWICE! My son is highly allergic to animals and his eyes will swell shut and he will be sick for weeks. So I got these and ran them for a week before he came to visit, he had no problems."
"My college age son has allergies and always wakes up feeling crappy, he said he actually felt good this morning."

"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."
"According to Shark, my air quality is a perfect 100% ALL DAY LONG. Even when: - My elderly Akita wanders by shedding fur like it's his job (and also pooting pretty non-stop) - I deliberately sprayed Lysol directly in front of it (for science!) ... The Shark? "100% perfect air, nothing to see here!" 🙄 ... But because it thinks the air is always fantastic, when I put it on auto/Eco mode, the higher fan rate is never triggered. ... It turned bright red, and said that the air would be clean again unless 60 minutes. It was back to 100 within a minute or two."
"I ordered 4 of these things and ALL of them sat off all day and night saying the air was perfect. ... All 4 of them did the same thing and would rarely come on."

""NeverChange" with "up to 5 years use" is purely a marketing gimmick. ... [The owner's manual for the HP150 series] 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] is different, claiming the cleaning area is "300 sq. ft." ... Either way, that's much smaller than the 650 sq. ft. rating. ... And obviously any mechanical filter's lifespan depends on pollutant concentrations."

"My Eufy X8 died a death"
"99% of first gen and second gen eventually become faulty after 1 year. ... I had 4 Mila, they all died the same way, replacement had the same fate, I gave up and threw all 4 of them away."

"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."
"Sensors read poor air quality all the time so the unit was running non stop."
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.
r/AirPurifiers • Shark Never change Air purifier ->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
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->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.
r/homeowners • The Best Air Purifier for Home to Buy now? Do you find the air in your house actually better since you started using it? ->I bought the shark never change as my first purifier just recently and I feel the difference with my allergies. The 5 year filter change really attracted me but after reading here a little more I might need to change it more frequently. I also tried the blue air for my office but didn't like it, I didn't feel any difference and it was noisy, I returned it and got the smaller shark never change .

r/Costco • Shark air purifier.. good? bad? ->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 😆
r/AirPurifiers • Can anyone convince me that airpurifierers are not a uneccessary waste of money ->Clears the air way faster and better than my Dyson. It’s a workhorse.
r/Costco • Shark air purifier.. good? bad? ->I’ve got a shark one and I’m still not converted if they work .
r/parrots • Anything I should avoid when looking at air purifiers? ->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.
r/homeowners • What's your best strategy for controlling dust in a large house with pets? ->I really like my Shark never change filters. They’re really quiet and pick up on air quality changes super quick. Easy clean
r/homeowners • To kind homeowners, the best air purifier? What do you use for home? ->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).
