Filter patches- Pack of 64 self adhesive and pressure cooker safe.

Description

Pack of 64 synthetic filter disks for grain and spawn jars.

These little filter disks are 0.22 micron and 20mm in size. On the back you will find the temperature resistant self adhesive sticker.

Synthetic filters can be attached to the hole of wide mouth canning jar lids and you need to clean and dry the surface before sticking synthetic filter paper.

HOW TO USE:

Use an 8mm-13mm drill bit to make a nice clean hole in the lid of your jar.

Remove any sharp metal around the hole carefully so nothing will damage the filter disk when you stick it in place.

Use an Alcohol swab to clean the area around the hole and leave to dry.

Once dry you may peel the synthetic filter disc from the plastic backing.

Apply the filter to the hole and press down to make sure the adhesive makes a good seal.

These filters are water resistant but are best kept away from direct water contact.
