best water purification tablets

Clean water is a given for life, but certain circumstances may call for purification of one's water source. The average adult cannot last more than a few days without enough clean water—the EPA recommends half a gallon of clean, fresh water a day, and no one wants lead, arsenic, bacteria, or other toxic contaminants in his or her canteen of drinking water. Tap water, municipal water, lake water, and bottled water are all at risk for contamination.

What Types of Water Purification Products Can Be Used?

Iodine

Iodine works surprisingly well as an antiseptic, and it's also a necessary nutrient for the human body. After applying this substance, the wait time for purification is thirty to sixty minutes. Iodine is effective against bacteria, viruses, and parasites, like Giardia. Warmer water works better for iodine. Water applied with iodine will have an iodine-like taste; this is normal, although some products may remove the awkward taste. Most iodine purification tablets last for up to six years on the shelf.

Chlorine

The wait time for purification is thirty to forty-five minutes. Like iodine, chlorine is effective against bacteria, viruses, and somewhat effective against Giardia. Most chlorine purification methods will be droplets rather than tablets. Chlorinated water has a bleach-like smell which will dissipate in the open air. The average shelf life is five years.

Chlorine Dioxide

This method of purification requires about four hours but kills a broader range of bacteria that other substances won't. Chlorine dioxide does not alter the taste or smell of the water once the purification process is complete. Chlorine dioxide is especially potent against parasites like Giardia but takes longer to have a full cleansing on a batch of water. The shelf life is four years in a dry environment.

The Verdict

Our Pick for the Best Water Purification Tablets

After a careful examination of our research, we have concluded that the Katadyn Micropur MP1 performs the best as far as quality and taste. The TAC-H2O comes in second for its price and the number of tablets that purify five-hundred liters per product. The Katadyn Micropur MP1 will perform better, but we recommend the TAC for those seeking a more economical choice.

The Aquatabs, Aquamria, and Potable Aqua brands did not meet our research's standards because of residue odor and taste issues, price per tablet, and insufficient information provided by the wholesaler.

Conclusion

Water purification is now one of the most important facets of life on this planet. Proper purification ensures health for both you and your family members, wherever you may be in the world, providing a convenient and lightweight option for clean water. Because of their flexibility and ease of use, water purification tablets are used worldwide by military and campers alike.

Our research suggests the Katadyn Micropur MP1 for the best quality water with taste, which is ideal for a camping vacation or hiking venture. The TAC-H2O is better for a cheaper, long-term option like an international trip to a third-world country or a military campaign.
