I don't know and I'm not sure why it matters. I can tell you it's heavier than standard paper coffee filters but the finest grind (I use espresso grind) goes through with slow pressure. Which is how it's supposed to work. I can also tell you that these little filters can be reused quite a few times without tearing. … see more I don't know and I'm not sure why it matters.

I can also tell you that these little filters can be reused quite a few times without tearing. I rinse them off and reuse them about 10 times. They turn brown (of course, coffee itself is a dye) but work just fine for delicious coffee every time. Hope this helps. see less I don't know and I'm not sure why it matters.

Cleaning the Aeropress is simple: once the water has been pressed through the coffee and out of the cylinder, all that is necessary is to push the used coffee out of the cylinder in the same way that the water had been pressed.

You must remove the plastic filter holder, of course. The used coffee grinds are pushed through and into the garbage or recycling bag. All that is necessary then is to rinse all of the parts of the Aeropress to remove any lingering grinds. The press is dishwasher safe, so I put it through the dishwashing cycle once a week or so. If you haven't tried Aeropress coffee, you are in for a treat. see less Cleaning the Aeropress is simple: once the water has been pressed through the coffee and out of the cylinder, all that is necessary is to push the used coffee out of the cylinder in the same way that the water had been pressed.
