Qualitative Filters

Qualitative Filters

Qualitative Paper Filters are extremely pure paper filters made from almost 100 % alpha cotton cellulose.
Ash content app. 0.06 %.
Filters are available as sheets, circles or pre-pleated ready to use. Frisenette's filters are also available in special cuts.
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 time and reduced risk of clogging.
