Laundry and clothes by far creates the most dust and particles in my home, probably yours too.
At night, with the lights off and the room dark, turn on your phone LED pointed at the ceiling. Look closely at the air just above the light, you'll see tiny little material threads and speckles. I do not like the idea of constantly breathing that in.
I've used an expensive HEPA air filter in my room and did some testing, lo and behold: when I checked the air with my phone LED it was absolutely teeming with material particulates (probably cotton, which I mostly wear).
The air filter creates a circulation in the room disturbing dormant dust and kicking it up into the air, but the filter doesn't seem to catch and contain this dust.
Alternatively, when I left my room window open without any filter and allow fresh outside air in, the phone LED test later reveals almost pristine air quality probably a 100x decrease in particulates.
I'm now trying out a water-based air scrubber, one that looks like a fish bowl. It agitates the water, non-ultrasonically, just using rotation, and sends air through the wash. Doesn't seem to be more effective than just letting fresh air in through the window though.

- magicalhippo 5y agoI had a lot of issues with an allergic-like reaction to my old bedroom when temporarily moving back to my parent's house while switching apartments. It was a bit dusty there, but visibly it didn't look too bad. I had noticed this before while crashing there every now and then, but hadn't thought much of it. But since I had to stay there for a while I had to do something. So I bought an air purifier with HEPA filter and let it work at full blast while I was at work. The first few days had a very noticeable improvement, and after five days I had no issues at all anymore.
- scotty79 5y agoIt's weird that people get alergic to stuff they grew up with. I grew up with cats. Never had a problem with them. My last cat died when I was 21. I moved out. I didn't have any contact with a cat for about 4 years. Bam, now I'm alergic to cats. Air purifier does wonderful thing for people with allergies. Thanks to it I could pretty much stayed off meds last year.
- mrob 5y agoMost particles by total mass, but not by total health risk. Your phone LED test only detects large particles that your lungs can remove (see https://en.wikipedia.org/wiki/Mucociliary_clearance https://en.wikipedia.org/wiki/Mucociliary_clearance ). PM2.5 particles are more dangerous because they can make it past the lungs' self-cleaning system, and the very smallest ones can penetrate the lungs and end up in the bloodstream. You need a laser sensor to measure small particles.
