Qualitative Paper Filters are extremely pure paper filters made from almost 100 % alpha cotton cellulose. Ash content app. 0.06 %. Available as plain circles and pre-pleated ready to use. Pre-pleated filters are more efficient compared to folded round filters, due to better utilization of the filter area. Thus pre-pleated filters lead to faster filtration and reduced risk of clogging.
