With all the current advancements in portable water purifiers within the last few couple of years, it is straightforward to be overwhelmed by the sheer number of products that you have available for your requirements on the market today. Luckily, the choice of portable water filters can be separated into two main types: micron filter purifiers, and UV light purifiers.

Here's things you need to know about both!

  1. Micron Filters: these purify water by straining it through some filters to remove any bacteria and contaminants from the water. The efficiency of those filters is measured by how small in microns a particle would need to be to have through the filter.

A micron is one millionth of a meter, or about one 25,400th of an inch.

So a 3-micron filter would stop any particle larger than 3 microns, but anything smaller than 3 microns would slip through.

The thing you need to know about micron filters: locate a purifier that filters to under 1 micron. what is a municipal sewage treatment plant?

Most bacteria are between 0.1-10 microns in proportions, but many purifiers will filter no more than 0.2 microns.

  1. UV Light Filters: these purifiers are truly amazing! They kill harmful viruses, bacteria, and protozoa by using ultraviolet light to "fry" their DNA.

The process with these units is normally to take a small wand of light and place it in to a receptacle of water for a quantity of time (usually 15 seconds to a minute) to be able to give the unit time for you to kill the harmful contents of the water with UV rays.
