    • Dosage: Typically 2 drops per quart of water for clear water, 4 drops if it’s cloudy.
    • Wait time: 30 minutes to 1 hour before use.

Mechanical Filtration

Mechanical filters remove physical contaminants like sediment and certain microbes through a physical barrier. These filters vary in pore size, often measured in microns.

Carbon Filters:

  • Advantage: Removes odors and improves taste.
  • Common types: Activated carbon, carbon block, granulated carbon.

Ceramic Filters:

  • Advantage: Can be cleaned and reused.
  • Pore Size: Often 0.2 to 0.5 microns.

Ultraviolet Light Filters:

  • Use: Disrupt the DNA of bacteria, viruses, and other pathogens.
  • Requirement: Clear water for effective use.

Water Quality Standards and Regulations

Water quality is pivotal to the safety and taste of your cooked food. Regulations ensure that contaminants are kept to a minimum.

Governmental Guidelines

Your government has established water quality standards that tap water must meet to be considered safe for consumption.
