Introduction

A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents for purposes such as providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools.

Challenges

Water filters can be expensive, require frequent maintenance or replacement, and filter limited types of contaminants. Reducing cost and complexity while removing as many contaminants as possible will require careful attention to details.
