It's Vital to Know Which Water Filters Are the Safest

While domestic tap water in most Western countries is regarded as of a reasonable standard, there have been a number of incidents from Miami to London, to Sydney, and back to the U.S.A. when drinking water filters and treatment went horribly wrong and contaminants entered the water treatment systems, requiring residents to boil drinking water, and resulting in illness for many.

Water filters in the home are important to safeguard health and cleanse water of chlorine and stray contamination. However, it is largely when camping or hiking or travelling to many developing nations that it’s essential to carry the best drinking water filter possible.

How Do You Know Which Personal Water Filter Is The Best? 

 

Water Contamination

 For starters you want a water filtration system that removes bacteria, e-coli, pseudomonas, staphylococcus, total coliforms, and parasites. You also want a light-weight and compact portable water filtration system. The SureAqua water filtration straw more than meets these needs.

In testing carried out across a range of portable water treatment options, 11 methods of drinking water filtration were tested.

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, SureAquaStraw pocket water filters are the safest, most effective option.

You see, most pocket-sized 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 is not able to 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.

SureAquaStraw has been independently tested effective in removing faecal coliforms, e-coli, standard plate count bacteria, pseudomonas aeruginosa and diminuta, staphylococcus, Cryptosporidium, and Giardia.

The straw uses an ultra fine 0.2 micron filter membrane, is totally reusable and provides up to 500 liters (132 gallons) of pure filtered water. Weighing only 24 grams (0.85 oz), with a total length of 205mm (8”), it’s an ideal backpacking, hiking, and camping water filter, slipping conveniently into your pocket and going anywhere to filter contaminated municipal tap supplies, lakes and streams, and bottled water affected by bacterial build-up.

For personal water filters that are kind on the environment, your health, and your budget, the AquaSafeStraw drinking water filtration system comes in the clear winners.
