How to Choose the Best Survival Water Filtration System.pdf
Depending on your situation, survival is sometimes a lazy man’s game. In comes the gravity
filter. This filter consists of a dirty water reservoir, an inline filter, and a clean water reservoir.
Gravity filters function by hanging the dirty reservoir anywhere above the clean reservoir and
letting gravity do its thing. The sacrifice is that often the reservoirs are frustrating to fill and
treatment can take longer than a pump style filter. Maintenance is pretty simple but must be
done frequently to keep the filter flowing well. Expect to get somewhere around 1500 liters
before the filter needs to be replaced.
