Does anyone just fac the intake side of these filters and keep using
for another few months?

The material can be washed and reused. The trick is keeping the
cardboard intact. I use something like greased lightning for smoke
particles. I also cut up the material for various filters. I can soak
and squeeze it out. Vacuuming will just get rid of large particles,
but will extend use.

After washing use water rinse.
