"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."
"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."
"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."

"All of my shark max filters lasted less than 1 year and I have replace filter error."
"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"
"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."

Shark 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.
r/AirPurifiers • Recommendation for 1000sqft Apartment in Los Angeles ->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 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) ->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.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->I have had one of these for a couple years. I know it's pulling in air because of all the cat hair I have to clean off of it. It also changes when I cook, a cat uses the litter box, my husband walks inside from smoking, etc. Sound like your might be a dud. The "air quality" detector is 4 small holes on the back. Bring a burning candle or put out a match near those spots to see if the reported air quality changes.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->I got two and it's getting super clogged with the senors. I put a new filter in and it's still 0%. Just make sure you clean it frequently.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->You also have it to close to the wall. The sensors that read the air are in the back. The directions say it needs to be like 6 inches away from the wall to work correctly. https://preview.redd.it/cu3dvtfrocne1.png?width=1440&format=png&auto=webp&s=a9aaba9a94e2bcba209f5c6033b693a6d48727a4
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->Mine drops to 0 whenever I cook anything. If I open the balcony door during the winter inversion, the number drops by a lot as well.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->Where do we get replacement filters? All of my shark max filters lasted less than 1 year and I have replace filter error.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->Mine didn’t change either until I started cooking and the smoke will make it change pretty quickly.
r/Costco • New Shark MAX air purifier think my house is cleaner than heaven itself (or it’s just broken) ->I just got one this year .. with mine it goes from 100% to like the 60s whenever I make popcorn or cook bacon in the house. Also whenever I turn on a humidifier in the room it always drops the air quality reading of it lol
