In an emergency or off-grid situation, there are several reliable drinking water treatment options, but some have drawbacks. Boiling is time- and energy-intensive. Iodine leaves a bad taste. Filtering or purifying is quick, easy, and reusable - but requires the right equipment.
Luckily, Real Goods has just the equipment for safe, reliable drinking water treatment in a variety of methods (including activated carbon filter, UV sterilization, and gravity filters) and sizes - from single-person day hike filter bottles to multi-gallon reservoirs for base camps or emergency shelters.
