Low PM count in his bedroom? Good for him, but try right after making your bed. Nobody is so perfectly defoliated that they don't have dust in their bedroom.
Also, cooking of all kinds spikes PM levels in my experience. Maybe eggs in a 100% clean non-stick pan are an exception, but I doubt it if you can smell it.
- hombre_fatal 1y agoI have a Winix air purifier from Costco in my bedroom, and it has a small air quality indicator light (blue -> yellow -> red) though I'm too lazy to look up what it's measuring. Surprisingly, making the bed, shaking out the sheets, or vacuuming doesn't make it change color. But farting in the room makes it red for minutes. An ever amusing phenomenon that makes my girlfriend and I chuckle on a weekly basis.
- jerlam 1y agoWinix air quality sensors (at least the ones I have) measure volatile organic compounds (VOCs), which is a little ironic since HEPA purifiers do little to remove VOCs from the air. Some other air purifiers like Coways measure particle pollution.
- adolph 1y agoWinix and many other brands can be equipped with activated charcoal filters which do absorb VOCs. For consumers looking for a way to remove VOCs in their homes and offices, Kroll adds, “air cleaning using activated carbon filters, a tried-and-true technology that doesn't rely on chemical reactions, is still the way to go.” https://news.mit.edu/2021/study-finds-indoor-air-cleaners-fall-short-removing-volatile-organic-compounds-1029 https://news.mit.edu/2021/study-finds-indoor-air-cleaners-fa...
