How to make rainwater safe for drinking is an issue that concerns our health officials and homeowners. Jody L. Grenga's affordable rainwater system includes a Berkey Light filtration system adapted for home use. Note, that is is just part of a much more complex system.
Berkey Water makes gravity fed filtration systems that are meant to filter out pathogenic bacteria, cysts and parasites as well as unhealthy chemical contaminates and impurities.
Although Jody Grenga utilizes them as part of her rainwater purifying regime, they are designed to stand alone.
Models include the Travel Berkey, the Sport Berkey backpack bottle, the Big Berkey, the Royal Berkey for large families, the Imperial Berkey for small to medium groups and the Crown Berkey for medium to large groups which will purify up to 6.5 gallons per hour.
Berkey Water (New Millenium Concepts Ltd.) is headquartered in Arlington, Texas.
