How to Make a Water Filter In An Emergency
During emergencies, clean drinking water may not be available. The ideal situation is that people have set aside water for emergencies. In the event that they do not have safe drinking water stored away, a clean source of water is still required. In many cases, this is not easily available. Piped water may be contaminated due to leakages in the water pipes or seepages from the sewerage system.
An alternative source of water from outside the home is from rain water or from water bodies like rivers, lakes, natural springs, ponds and streams. It is always good to assume that water from these sources is not safe for drinking and should be purified first. There are various ways of purifying water such as boiling, disinfecting and filtering. Filtration as a water purification method is usually done after another type of purification has been carried out. This is because filtration on its own does not get rid of harmful contaminants in the water like bacteria, viruses, protozoa, minerals and chemicals.
Filtration usually gets rid of any floating particles in the water and depending on the type of filter, it may get rid of bad odors and tastes, so you should know how to filter water in a disaster situation.
