Guys,

A question. Do you buy sterile membranes to filter products?
Or do they buy non-sterile and use BA, or something else?
I ask because in my country, it is very difficult to find sterile membranes, I am thinking about buying non-sterile membranes in China

Sterile of course, using non sterile defeats the purpose of filtering lol. BA is to prevent bacterial growth, filter is well, to filter.

China offers lots of sterile filters too, look harder. Ali express has so many to offer.
 
Thanks!!

I produced it in 2013/14, but I used a syringe filter.

I'm going to last longer but I found sterile nylon filters on Aliexpress, but only 1 supplier. I will look better
