Quick Answer
After storage, some of the best water filtration methods include activated carbon filters, UV light purifiers, and ceramic filters with 0.2 micron pores or smaller.
Effective Activated Carbon Filters
Activated carbon filters are effective at removing chlorine, bacteria, and volatile organic compounds (VOCs) from stored water. Look for filters with a high surface area, such as those with a rating of 10,000 square feet per gallon. This will provide reliable protection against common waterborne pathogens. Some popular options include the Berkey Black Filter and the AquaSafe Water Filter.
Ultraviolet (UV) Light Purifiers
UV light purifiers work by disrupting the DNA of bacteria and viruses, rendering them unable to multiply. These units are particularly effective against Giardia and Cryptosporidium, two common waterborne pathogens. When choosing a UV purifier, select a unit with a UV-C wavelength of 254 nanometers, which is the most effective range for killing bacteria and viruses. For example, the SteriPen UV Water Purifier can provide up to 99.99% removal of bacteria and viruses.
Ceramic Filters with Small Pores
Ceramic filters with pores of 0.2 microns or smaller are highly effective at removing bacteria, viruses, and parasites from stored water. These filters work by physically blocking the passage of pathogens, rather than relying on chemicals or UV light. Some popular options include the Sawyer Mini Water Filter and the MSR TrailShot Water Filter. When choosing a ceramic filter, look for one with a high flow rate and a durable construction to ensure reliable performance over time.
