"My college age son has allergies and always wakes up feeling crappy, he said he actually felt good this morning."
"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."
"I have one and it gets rid of odors, dust particles, and other nonsense pretty quickly."

"It’s been kicking on a lot lately because it detects bacteria and viruses in the air. 🦠"
"I’ve found the readings between them to be very consistent and accurate."
"Also it has a button to switch between air quality views and show you what (PM 10, PM .5, PM 1) is fouling up the air quality. Also shows time to clean air and percentage of the air that's clean."

"Only have to change the filters every 5 years."
"I've had it for about a year now and didn't even need to buy a new filter for it yet."
"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’ve been running a Shark air purifier for about 3 months with no noticeable reduction in dust"
"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."
"It does NOT like sauerkraut, burnt eggs or fried tortillas 😆"

"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."
"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 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."

GFFFFR 1.0I got a fairly small apartment with 2 bedrooms upstairs and a small basement and I got a Winix T830 in my living room/kitchen area(with my setup basically in-between the 2) a Winix C535 in my kids room a Shark Compact Never change in my room and a Shark Hp100 in the basement. I'd say it's definitely not overkill lol. I've definitely preferred the Winix over Shark
IamNotARobot01010110 1.0I have two Shark air purifiers and I really like them so far. Pleasant fan sound, auto and manual modes, several speed settings. I enjoy looking over and seeing them go from red to yellow to green after we cook something smokey. Here is a link: https://www.homedepot.com/p/Shark-500-sq-ft-HEPA-True-Console-Air-Purifier-in-Whites-with-Nanoseal-Cleansense-IQ-Odor-Lock-HP102/320485847
jpotts79 1.0If that isn't already a ear purifier with a HIPA filter I wouldn't recommend getting one that also takes VOCs out of the air like a shark air purifier from Walmart or order one off in shark website It'll also help with wildfire smoke etc.
I bought a shark air purifier in 2023 when all that wildfire smoke hit the first time and it's done a good job with the wildfire smoke and everything including VOCs. But it's not the never change filter. It's the 102
stetkos 1.0Look into getting the Shark clean sense IQ air purifiers. The model for a 500 Sq ft room is only $150 on Amazon right now. I have one and it gets rid of odors, dust particles, and other nonsense pretty quickly. I've had it for about a year now and didn't even need to buy a new filter for it yet.
Quirky_Ebb_7335 0.4I have a large shark and then some smaller ones around my apartment. The previous tenant had cats and there was SO much cat dander even after hiring deep cleaners TWICE! My son is highly allergic to animals and his eyes will swell shut and he will be sick for weeks. So I got these and ran them for a week before he came to visit, he had no problems. I swear by air purifiers, especially for people with allergies and asthma.
Empty-Knowledge2869 0.1Shark has never change filter air purifiers on their clean sense IQ models now and they have built in air quality sensors and auto mode which is economical as it only turns on the fan when it senses something in the air. Also it has a button to switch between air quality views and show you what (PM 10, PM .5, PM 1) is fouling up the air quality. Also shows time to clean air and percentage of the air that's clean. I have two of them. I also have two of the Vornado AC350's. Their filter replacement are reasonable and the carbon filter can be easily upgraded on Amazon for a reasonable price.
weary_bee479 0.1We have a purifier on every level of the house, 3 in total. They are definitely game changers and help with smell, but also dust. We have two shark air purifiers with hepa filters, looks like it’s 120$ 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.
ALrredditt 0.1I 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.
amphetaminesfailure 0.1I 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.
B00k_Worm1979 0.1I 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 😆
