One Filter Paper
Filter Papers – Whatman
These are Whatman pre-pleated filter papers, 320mm diameter: buy just one or however many you need.
At Pell Wall these are the filters we use when we chill-filter our finished perfumes (filtration is best done after the period of maturation to ensure that no further materials will drop out of solution after filtration).
If you have an account with Merke you can buy packs of 100 of them directly from them.
