That's why I use condenser washer-dryers that exhaust through the water drain.

They don't ever get "dry", only the clothes. And though they have a filter, it's in a water drain pipe, so it's never dry. Even the rubber-seals that hold onto every piece of sock-fluff, they are wet at the end of the cycle even if the top of the seal is dry, the clothes dry and hot, and the metal drum hot-to-the-touch.

I looked at "normal" dryers that have those huge air-vents that clog with inches of dry lint in hot air and said "Nope".

Condenser washer-dryers is the way to go. One pipe with water in, one pipe with water + waste out. No vents, no dry air, no dry lint filters, nowhere for lint to collect and heat up.
