How does a filter works?

First, the large internal surface area physically traps sediments and contaminants. Then, activated carbon acts like a magnet for compounds like lead and volatile organic compounds as water passes through. Finally, chemical reactions inside the filter reduce chemicals like chlorine on contact.

Why do filters work?

How do water filters work? Water filters work as a physical barrier that can block or trap debris (for example sand) and sometimes bacteria from passing through. Generally, the speed of the water flow will depend on the size of the gaps in the filter barrier or membrane.

How does air filter work?

Air filters work by drawing unclean surrounding air to pass through their filter medium with fine openings. The unwanted particles larger than those openings are trapped inside the filter medium and are separated from the passing air. The air leaves the filter with significantly reduced particle content.
