Fibre glass filter grade?

j_mchattie · 8 Jul 2013

Hello,

I made a 6x 4" 12v DC fan extractor hatch for my loft - it works really well to pull cool air up through the house and out the loft.

I'd like to attach a filter to the loft side so if it's windy the glass fibre from the insulation in the loft wont come in to the house.

My question is, what material should I use? I can see lots of HEPA filters online and also lots of other types of panel filters but Ideally I want a big sheet of the P2 face mask material, or similar. Anything which will stop the glass coming down.

Any ideas? Obviously I need it to be thin enough that I still get decent air flow.

Thanks
