"I’ve been running the Shark Clean Air Eco in my bedroom for a couple months now and its whisper-quiet low setting truly disappears in the background."
"it's pretty quiet even on its highest setting (like a low fan). ... If I keep it running all day and night, it's usually whisper quiet at night since it already cleaned the air during the day."
"They’re very quiet I never hear them"

"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."
"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."

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

"Mine stopped working after 2 months."
"All of my shark max filters lasted less than 1 year and I have replace filter error."
"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."

"It does NOT like sauerkraut, burnt eggs or fried tortillas 😆"
"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."
Balamuwa 1.0I’ve been running the Shark Clean Air Eco in my bedroom for a couple months now and its whisper-quiet low setting truly disappears in the background.
CalmSeaweed1360 1.0I grabbed the Shark Clean Air Eco from Costco when it was on sale and I’ve been running it in my bedroom for a few months.

Last-Attempt-217 1.0I picked up the Shark Clean Air Eco on sale last spring and it’s been solid at trapping dust and pet hair, but when I fry bacon it takes closer to 40 minutes to clear the haze.

sissasassafrastic 0.6Please read the AutoModerator comment. Air purifiers aren't good at reducing *visible* dust as it's larger and heavier than "invisible" pollutants like PM10 and PM2.5. The same goes for pet hair. Sans is terrible. Shark is mediocre. Avoid both. Coway is generally one of the highest quality consumer-grade brands. Winix is good, more mid-grade. Blueair has an always-on ionizer. Some people want to avoid this because of possible health effects associated with ionizers or changes in gaseous air chemistry. Per the AHAM 2/3 rule, a space 600-800 sq. ft. needs minimum Clean Air Delivery Rates (CADRs) of 400 CFM - 534 CFM. Unfortunately your budget doesn't support a single large or multiple conventional HEPA purifiers. (An example that meets CADRs would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox).) If you still want a conventional HEPA purifier, go with the [Winix C909 at Costco](https://www.costco.com/p/-/winix-c909-4-stage-air-purifier-with-wi-fi-plasmawave-technology/100842491). It's a bit of an energy hog (95 W) and somewhat loud on the highest setting called "Turbo" (60 dBA per the Decibel X Android app), but it's good value for money. The C909 has PlasmaWave, a bipolar ionizer. You may want to keep this off if you have pet birds. Another option may be the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro). It uses Efficient Particulate Air (EPA) E11 filters, which is two filter classes below HEPA H13. Top composite CADR is 413 for the CARB Edition. Price is $159.99. Keep in mind CADRs listed by purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning effectiveness.
I think I'm parsing your comment here correctly, but... don't buy Shark. It's a lousy brand with very misleading marketing—e.g., "NeverChange" filters. They don't publish Clean Air Delivery Rates (needed to size a purifier for wildfire smoke particulates). It also has a tiny amount of activated carbon so it's useless for VOCs or other gases. We've seen multiple issues with Shark's air quality display malfunctioning on r/AirPurifiers. You need many pounds of activated carbon or other sorbent media for wildfire smoke gases, VOCs, or odors. And even then, plain/non-chemically treated activated carbon doesn't have high removal efficiencies for all gaseous species.
Yeah, Shark is mediocre and uses misleading marketing. Frequent issues with the AQI display as well.
liquidnight247 0.4I just got an inexpensive Shark max never Change and am surprised how much of a difference it makes, also to stale air. I only suffer from minor allergies, for serious cases i would definitely upgrade to a better model. But do get one.
Empty-Knowledge2869 0.2Shark 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.
