Is there any effective method for air purification that doesn't involve disposable supplies?

No, sadly. Maybe trucking in liquified clean air and boiling it off into your house to create a positive pressure.

  I wonder how feasible it would be to construct an elastic air filter. When it's full you could take it outside, stretch it out, and blow all the crap out with a leaf blower.

    Maybe some day! But current materials science doesn’t have anything like that. It’s not usually about physical hole size, but rather electrostatic attraction (in the case of HEPA filters) or adsorption (in the case of activated carbon). There’s no “hole” to open to let things drop out. It’s a surface that things are somewhat bonded to.

      Maybe you could tote the machine outside, stretch it, and then electronically reverse the charge to make it easy to blow off contaminants.

Maybe bubbling the air through water or a mist/air counterflow like scrubbers in coal plants? Throw in some UVC light source to keep germs from growing in the water. Are there UVC LEDs yet? There also are electrostatic filters but they produce ozone.

  There are, and they're finally getting cheap! https://www.ebay.com/itm/114268507196 https://www.ebay.com/itm/114268507196 $4-5 USD per unit really isn't bad (plus power supply and resistors or controllers) compared to what they were a few years back. (saw these on extractions & ire, the ones he got must be very durable since he way way way overpowered them)

  Joan you have to do something with the dirty water ;P.

The carbon filters like the one I linked could have been designed so that the activated charcoal could be replaced. Unfortunately, The companies who make these filters choose profits over environmental sustainability.

You can look into the electrostatic cleaners with a washable filter

  Do those actually work, though?
