Aerogel for filtering?

[alien]

Anyone know how well Aerogel (or "frozen smoke") is at filtering air? I can find that it's a very good comet dust collector, and would be very effective at stopping particles, however not too sure about the actual flow of air through the solid.

How many people actually have used Aerogel at anytime? For insulation or what not.

Does anyone know rough costs of it too (and what type it is [preferably silica])? In whatever units they can find? e.g. grams, cm^3, sheets.. e.t.c.

Does the job perfectly.

I use it to trap mice personally. Spray it in front of their hidey holes, make some noise like a good mature cheddar and watch the little critters run smack into my trap.

I believe the statistical data from the last census showed that less than 3% of the population use Aerogel, however that was a slight increase from 10 years previous. Also it appears Quakers seem to be the group most likely to have Aerogel in the cupboard.

I picked some up from my local yesterday, $3.95 on special.

i cant see anywhere that its used as a filter. seems its used more to collect stuff/ have stuff bind to it, not filter. looking at pics of a flame underneath a block of it, and a flower unburnt on top, id say it wont flow much if anything

It's pretty much solid. You can get some made from different stuff that is crazy good sound insulation now too (light and good). I don't think it would be used much if at all in Australia. But very popular in Europe where they have decent insulation in their houses

OK, i guess not many people use it down here or have it. See the interesting part is it's 99% air. And it works well at filtering oil out of water.

Looks like it's only using it to insulate homes and vehicles.
