Poret foam

[ElectricBlueSeanBurch]

I found a website that sells sheets of poret foam, but they don't measure it in microns (100 microns, 50 microns ect) they list it in ppi. Anyone know what this is? I googled it but couldn't find any info

pores per inch?

It is pores per inch. More/higher number means that it filters finer because the pores are smaller allowing only small particles through.

Is there any way to convert it to microns? I'm looking for something <30 microns. They list 10, 20, 30 and 45ppi

I love Poret and use it in several places at the shop. It is nowhere near micron filtering. You need ceramic filters for that or possibly carbon.

I don't think there's a direct comparison... 45 would obviously be the best but I doubt that would even be to 100 micron...
