"They do a good job of removing smoke from the room."
"The thing I noticed most and love about is that I no longer have the smell of my upstairs neighbor cooking wafting in."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."

"Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something."
"The sensors are amazing. ... Yes whenever I cook or smoke they instantly kick on and work really well."
"great to put it on eco mode , as it detects poor air quality it automatically switches modes to higher setting and shows it as purple or red and once air is back to being good it goes back to eco mode and shows blue."

"This one is my favorite for many reasons but mainly because you don’t have to constantly buy new filters."
"It says the filter can last up to 5 years. ... I appreciate not having to spend more $$ on filters at least in the next couple of years. ... I barely remember to change my air filter in the basement so anything to make my life easier is a plus. ... The tiny research I did on my phone in the store said I should be able to not have to change the filter for a few years, which is a huge plus to me."

"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."
"It's no wonder the filters last for 5 years, the thing never runs. ... They are not "purifying the air" if they are not moving the air through the filters."

"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."

"The “never change” filter is a lie - yearly changes are necessary"
"All of my shark max filters lasted less than 1 year and I have replace filter error."
"I got two and it's getting super clogged with the senors. ... I put a new filter in and it's still 0%."

"Also uses sent pods which just add VOCs to the air."
"It comes with SCENT PACKETS. Air purifiers remove contamination from the air, they don’t add things to it!"
"the scent pods are horrendous! ... I don't like anything scented, so don't plug them in. It's an option."
Looks the same as ours we got a year ago. We have a dog, three cats, and two children. Really the only time it goes low is if we are cooking bacon. I usually just leave it at level two speed. It does pick up hair and what not. Usually open it up and pull hair off of the outside of the filter every month.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->I got a shark one from costco. It worked so well that I went back the next week and got another for the upstairs. the first is in my office with my rat cage.. the smell is virtually gone from them. The other is in my wife's library with the litter box for the cats. Smell is also gone.. Can't believe I didn't do this sooner.
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 have had mine for a few months and mine works great. It’s super sensitive. It is on auto and I can see it working when I’m cooking and when my HVAC turns on. I have a 105 year old house and it has noticeably helped my allergies. Not sure if maybe it’s the placement? No real idea honestly.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->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/AirPurifiers • Best Value Air Purifier? (Coway, Winix, Blueair, Shark, Sans, etc) ->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. 🦠
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? ->As soon as we took this thing out of the box and set it up I knew it didn’t actually work. I’ve had other air purifiers and this thing just never ran. Returned it that same night.
