  • Click Here to jump to top 5 brands on the market..

When talking about water, there is no room for error. Therefore it’s essential to purchase products that are high quality and reliable!

The effectiveness of your pill can mean the difference between life and death as certain pathogens in contaminated sources can cause serious illness or death.

Therefore, I’ve reviewed pills from the top five brands on the market to help you make an informed decision (see end of this article for product comparison).

The Secret Science Behind Process of Purification

The chemicals used during manufacture process of these tiny capsules destroy bacteria, parasites and viruses, making almost any source of H2O safe to drink! While these are an essential part of any survival kit, they will not remove large debris, like branches, leaves or dirt.

Please note!

You will need to use some kind of filter to get rid of these first! This can be something as simple as a t-shirt or a filter designed for survival situations!

Tiny Pills Packed with Whole Chemical Lab

There are 4 main substances that these products consist of:

  • Chlorine (Cl) –  This substance is highly effective at destroying pathogens!
  • Iodine (I) – All versions made with iodine will kill many but not all common pathogens.
  • Chlorine Dioxide (ClO₂)
  • Sodium Dichloroisocyanurate (NaDCC)

Regardless of which active ingredient is used, these tablets can sometimes leave behind an unpleasant taste. Iodine neutralizers can be used to eliminate its chemical flavor, but water treated with chlorine will need to sit uncovered to let the taste evaporate!

The Best Fire Pistons out There

Unlike other purification methods, pills are incredibly easy to use. They do not require any special equipment, and they work quickly. Effervescent models will quickly and easily dissolve in water, simplifying the whole process.

Here’s how it works:

  1. Add one capsule to every liter of water (This depends on each brand individually!!!).
  2. After 5 minutes give the container a good shake to quickly dissolve and mix substances from capsule into it.
  3. Close the container.
  4. Allow the mixture to sit for at least 30 minutes!

After it has purified the liquid, you may want to leave it to sit uncovered to the chlorine evaporate.

Minimum of 2 Years Shelf Life?

If you’re stocking up on survival or emergency supplies for your home made kit, one of your biggest concerns will be the expiration date of the products you purchase. One of the most surprising and beneficial aspects of water purification tablets is that they last for incredibly long period.

When stored properly, they can remain effective for several months or years. Chlorine based capsules tend to last longer than iodine ones with some lasting around 24 months.

Pay attention!

Oasis brand, using NaDCC as the active ingredient, have an impressive shelf life of five years!!!
