The least effective drinking water filtration was through granulated activated carbon and ozonation. Best performing were solid carbon block filters, membrane water filtration, and plain boiled water, while options such as chemical disinfection, ultraviolet treatment, reverse osmosis, distillation, and bottled water were mid-range.

Of the top performers, Sure Aqua products water filters are the safest, most effective option.

You see, most portable water filtration systems use chemicals to purify drinking water. Iodine is one of the main filtration mediums used. However, there are serious reasons for either not using iodine filters at all or just short term.

Children and pregnant or nursing women, those with thyroid disorders or immune deficiencies are recommended not to use iodine-based filters, and no one should use them long-term. The carbon water filtration option cannot filter certain bacteria such as e-coli and pseudomonas, and environmental care must be taken in disposing of both options while boiling water the required length of time is just plain inconvenient in most circumstances.

Sure Aqua products has been independently tested effective in removing essentially all bacteria including cryptosporidium, and giardia.

For personal portable water filters that are kind on the environment, your health, and your budget, the Sure Aqua products drinking water filtration system comes in the clear winners
