What to Consider When Buying
There are more to the best survival water filters that its type of design. It has to be effective in filtering water, and there are also essential features that you need to consider before buying one.
Filtration vs. Purification
Filtration and purification work differently, although most people use these terms interchangeably.
Filtration happens when water passes through a sieve, which can either be biological or through a chemical process. The carbon filter is a common method used in infiltration systems. It eliminates most contaminants, odor, and color but isn’t 100% effective in eliminating certain chemicals and viruses.
Purification, on the other hand, removes any impurities in the water. It takes contaminated water and then turns it into clean water, free from bio-contaminants, pathogens, and chemicals.
The best survival water filters come in varying sizes. Suppose you want something compact that would make a fantastic companion while backpacking. There are lightweight options like straw and bottle filters. They take little space in your backpack and adds little to no weight to your luggage.
Ease of Use
If you’re looking for the best survival water filters for emergency preparedness, your best bet is something that can produce clean water quickly. It should be easy to set up the filtration system and won’t take much longer to filter the water. Electric-powered filters are not the best option in most cases as they require power to set up and use.
Effectiveness when choosing the best survival water filters depends on how fine the sieves of the filter are. You can gauge that on the water filter’s micron level. The smaller the rating is, the better it is at filtering water contaminants. Bacteria is usually at 0.2 microns, so a water filter with a 0.2-micron rating should be sufficient. A filter smaller micron rating like 0.1 should be able to remove viruses and cysts from passing through.
Capacity or Output Speed
A high flow rate or output speed makes it quicker to harvest clean water from a source. Larger filters, except for gravity-fed types, usually produces drinkable water at a higher speed than smaller variants. Straw types, for example, uses a sip-and-drink mechanism.
The water’s taste quality depends on how effective the filter is from getting rid of microorganisms and chemicals. The best survival water filters should be able to filter out the funny taste of contaminated water. Activated carbon does the job well in this case, so a water filter with this feature should give you good-tasting water.
Getting the best survival water filters can be your lifesaver in case of emergencies when no potable water source is available. Our best pick for that would be the Survivor Filter PRO X Electric as it can remove 99.9% of bacteria, giving you clean and safe water to drink.
