Whether you are planning a remote camping trip or a kayak tour along a canyon river, you have to provide yourself and your travelers with a safe source of drinking water.

Although there are various ways to collect water that is available in the wilderness, this is not always an easy and reliable option. Sometimes it may be impossible or at least impractical, because the water source is too far away, the water is flowing too fast, or the pumping equipment is not available.

Hence, one of the best ways to provide your campers or hikers with a safe, clean source of drinking water is by using a water purification tablet.

Water purification tablets are usually based on the following technologies:

  • Chlorine dioxide
  • Iodine
  • Ozone
  • Reverse osmosis
  • Ultraviolet radiation

These technologies differ in the amount of energy they require to operate, the amount of time it takes for them to purify water, and in the level of residual effect they leave in the water they produce. Each water purification tablet has its own advantages and disadvantages that are based on the technologies it is based on and the way it is developed and manufactured.

Frequently Asked Questions (FAQ)

What are the best water purification tablets?

Water purification tablets are a great choice for a quick, easy method for treating water. Here we have listed the best water purification tablets which you can use for this purpose.

People who do not like using water purification tablets, or who do not always carry tablets, can also use one of our other water purification methods, such as a water purification bottle or a water purification straw.

Do water purification tablets really work?

Yes, they do! But ensure that the brand of water purification tablets you purchase does have the NSF approved seal; this is a stamp of approval from the National Sanitation Foundation to ensure the product is free of harmful materials. However, it’s important to note that it may not purify water thoroughly. The tablets are in fact a first line of defense made to kill large, visible contaminants such as giardia, cryptosporidium, and other bacteria and viruses which are unlikely to be affected by the pills. For safety reasons, you might still want to filter the water before drinking it because some contaminant in the water may pass through the purifier.

How many water purification tablets do I need?

Follow the package instructions. Most purification tablets are effective for up to 12-24 hours and you should plan on using a new tablet every 24 hours. So to cover a 1 week backpacking trip, you’ll want approximately 12 tablets.

Does Aquatabs kill viruses?

No, Aquatabs are not effective at killing viruses. Most viruses are too small for water filtration tablets to remove, and even then, certain viruses can damage the filter in your water bottle or water container and still be able to thrive.

The UV filters can kill bacteria pretty effectively, but because viruses are larger than bacteria, there will be more room for viruses to pass through with water filtration tablets.

Conclusion

Although almost everyone is aware of how bad drinking unfiltered water can be for your health since most of us have drunk it at one point or another in our lives.
