Description

Single stage filtration system for purifying water

Technical Field

The invention relates to the field of filtration, in particular to a single-stage filtration system.

Background

A single stage filtration system is one with a threaded end cap that opens and closes by moving up and down. The filter element bottle body needs to be unscrewed when the filter bottle is disassembled. If the body and end cap are screwed too tightly, the body is too tightly pressed for removal.
