What is the science behind water filters?

Water filters use physical, chemical, or biological processes to remove impurities from water. They can include activated carbon, reverse osmosis, and UV light.

How does activated carbon work in water filtration?

Activated carbon works by adsorbing contaminants onto its surface. It has a large surface area that traps impurities, improving water taste and odor.

Are there any contaminants that activated carbon can't remove?

Yes, activated carbon is less effective against certain contaminants like heavy metals, nitrates, and some microorganisms. Additional filtration methods may be needed.

What is reverse osmosis and how does it differ from activated carbon?

Reverse osmosis uses a semi-permeable membrane to remove a wide range of contaminants, including dissolved solids, while activated carbon primarily adsorbs organic compounds.

Can you explain the role of UV light in water purification?

UV light purifies water by inactivating bacteria, viruses, and other pathogens. It disrupts their DNA, preventing them from reproducing and causing illness.
