I can confirm that you really don't want to breathe in any of that crap.

A year and a half ago I developed symptoms of what was some form of bronchitis. Lots of mucus, constantly coughing, etc. I was pretty freaking sick. I tend to wait some things like this out, but it wasn't going away so I went to a doctor and got some medications including albuterol and some kind of steroid (prednisone, I think). It got a little more manageable, but didn't seem to be getting any better.

One day, I realized how much of a dumbass I was the whole time.

The apartment I was living in had a laundry room, but it was tiny and I got tired of both hauling laundry up and down multiple flights of stairs and having to fight for time with the few machines that were there. I bought a small washer and dryer pair from Black & Decker which were designed for apartment living. Kinda off topic, but there were no hookups in my unit, so I had to jerryrig a water connection using some collapsible garden hoses that connected to my shower and its drain. Was kinda hilarious but worked great.

I made the mistake of thinking that I could just allow the dryer to blow through two sets of lint traps and have a fan blow air out of the window to manage moisture and remaining lint making it through. What I didn't realize was how inadequate the traps were. Because I worked from home, I spent a lot of time in that bedroom, including when the dryer was running. I was breathing in all sorts of stuff without knowing it.

Once I stopped hanging out in that room while the dryer was running, bought an air purifier, and made sure to frequently clean my apartment of dust, my symptoms rapidly started to go away.

If I had to do all of that again, and I couldn't just have the dryer blow directly out the window, I would find some way to have it do a second pass through a HEPA filter, perhaps after drying the air with something like calcium chloride.

I shudder to think of all the microplastic fibers that remain somewhere in my body.

There's still good fabrics out there you just have to pay for them. I've mostly replaced my wardrobe now with natural undyed cottons and wools from the likes of "unbleached apparel" and "industry of all nations". There is cotton grown in new mexico, socks spun in north carolina. "Filson" makes a few things in Seattle. Don't skip the stuff made in Peru or India neither.

I just try to buy natural or the semi-synthetic cellulose fabrics, there's quite a variety.

Natural fabrics are cotton, silk, wool and linen of course, but the semi-synthetic fabrics like the rayons (viscose, modal, "bamboo", Tencel, Lyocell, Bemberg, and some sorts of artificial silk) are wood cellulose chemically rearranged so they're just cellulose when they reach you.

The fabric referred to as Acetate is cellulose acetate, so not pure cellulose like cotton and rayon but is just as biodegradable and contains no petroleum plastics.

Of course the production process for viscose rayons (not Tencel/Lyocell/Modal - those use a different process) isn't great. It uses carbon disulfide which is a neurotoxin. However it's not a persistent pollutant. Modern factories in the west try to capture and recycle as much carbon disulfide as possible (it's released from the rayon during processing and can be fed back in to the process) but as a lot of factories are in countries with poor controls on this it's hard to tell how many are doing this.

I don't have any clothes as old as yours though for sure, but line drying generally helps your clothes last longer. I'm so glad I live in Colorado. It's a warm winter, but it takes like 3 hours to dry stuff on the line (especially synthetics). Of course that means all my synthetic fibers are literally billowing into the air I guess. Still, we've been going without a dryer for about five years now and I've had no regrets.

I have recently started refusing to buy all of this plastic filled clothes. If I see any % of it I don't buy it. Period.

I spend much more upfront for clothes, but I gain a lot long term. Clothes don't look terrible after few washings and they tend to last forever.

I wonder what impact those plastic bits used to attach tags to clothing have on durability. Woven/knit products kind of have a countdown that starts when threads break, and those tags tend to mean your clothing already has broken threads right from the store.

Yeah, I've started being a bit concerned about inhaling all the tiny plastic fibers every time I clean the filters and wondering what could be doing to my lunges.

Do not dry your cotton shirts in the dryer. It's as easy as that. You hang them up and let them air dry. They'll last forever.

I had the exhaust vent disconnect. Still think of the amount of microplastics I must have inhaled then

I hold my breath when I clean the lint trap, replace it and start the drier, then leave the laundry room and take a breath. I’m still probably inhaling some fibers but it makes me feel like I’m doing something.

My following comment is not about clothes, but not long ago I washed some curtains that were hanging in a window for some fifteen years. The amount of lint that came out in the dryer was incredible. I'm talking inch-thick wad on the filter screen, growing another inch with continued drying, after being removed.

It was probably due to years of UV breakdown of the fibers from daylight.

Hang dry clothing to avoid the drying machine issues all together and it is much gentler on the clothing.

I hadn’t considered that, but I have also paid to get my laundry done for the last 15+ years, it is the greatest luxury.

You are actually seeing something the linked article doesn't even mention: fiber length.

Not all cotton is created equally. "Egyptian cotton" was long prized because of the long fiber lengths. Cotton fibers are very smooth and slick, and only stay together in thread because of friction along their length as they lay with neighbor fibers (often twisted, where friction becomes exponential instead of linear). Short-fiber cotton is cheaper and easier to source; ergo, cheaper clothing tends to be made of it. Short fibers are also much more likely to slip within the thread under heat, lubrication, and motion (washing and drying). Obviously, they are also more likely to completely fall out of the thread, creating lint.

This is really only true for cotton and very similar fibers. Linen fibers are generally all multiple inches long, so there's less of a quality issue (they are made from rotting away everything but the longitudinal support fibers of the plant stalks).

Wool varies greatly in surface texture, especially after modern chemical processing, and fiber length isn't an issue because the fibers are also inch-long or better. It shrinks, however, because its friction is SO HIGH that it won't give up (stretch back) once it gets bound up.

Silk fibers super slick, but are several yards/meters long; a single cocoon is made from a single thread. They are much slicker than cotton (and therefore harder to hand-spin), but by the time they are made into thread they have plenty of surface friction maintaining their position in the thread.

Artificial fibers are as long as the production shift lasts, so effectively infinite.

Velva sheen makes some decent sweats and hoodies.

> Is anyone else freaked out about cleaning their dryer's lint filter given all the new fabric materials?

I used to be. So I spent quite a lot of time researching the issue. Not just google searches, but actually speaking with biologists.

I think that the current microplastic scare is overblown. The "credit card worth of plastic in brain" articles are just ridiculous. Biologically, the body has defenses against microscopic contaminants in blood. There are special immune cells that "eat" insoluble particles and then get excreted (typically in bile).

It looks like I'm not alone in my bafflement: https://www.motherjones.com/politics/2026/01/scary-research-... or https://www.vox.com/climate/475004/microplastics-research-fa...
