What's the absolute or biggest size?

Most water systems only advertise the smallest hole but not the largest one.

Logically, a hole size 0.4 microns is sufficient to trap the smallest water borne cyst with a particle size of 0.5 micron. And a hole size of 0.1 microns is sufficient to trap dissolved chemicals and heavy metals in the water.

Every filter unit will have different hole sizes, so don’t be cheated by units claiming to have a hole size of 0.00001 microns. Not only is it a sales gimmick but also cheats uninformed consumers,

The problem with water in Asia is the high sediment content, due to aging leaking pipes. If mud sediments can get into your piped water supply, so can other contaminants as water pipes cross roads, farms and factories
