I don't know the answer for his particular filter material, but washing was not recommended for other carbon filter pads I used in the past.

Q: Can I use this filter for mask(face mask) liner?

Because of the micron size of viruses, only very specific masks have any chance of filtering them out-and even those ones HAVE to be professionally fitted to have any efficacy (like the N95-which even when professionally fitted and used properly only stops 95% of virus micron size) and MUST be worn under very strict guidelines otherwise it offers no more virus protection than the cloth and surgical masks- which do not do not stop virus micron size from getting thru at all. To actually stop virus micron size you will either have to invest in a professionally fitted N95 and strictly follow the wearing protocol or to purchase a professionally rated respirator that guarantees to filter micron size of 0.01 or under (such as what virologists use in labs). Do not forget that viruses enter thru mucous membranes and so eye protection (such as goggles) will also be a MUST if you want to be truly protected from anything with a virus micron size. Hope this helps!

Q: It says it's 1/4 inch thick in the picture and 1/16 in thick in the description, which is it?

1/16th, but can be doubled, tripled, or quadrupled, etc., in thickness.

Q: Can this be put inside the air opening of a window AC unit to block out the light that comes through the vent?

I would rate its opacity to approx. 70%-80% (when clean and new). Remember, this is designed to trap small dust particles. As it does its job, it will become more opaque as well as not pass air efficiently.
