When you are outdoors whether it is camping or hiking, water purification is an essential element that should not be overlooked. Not all water sources are safe, even if the water looks crystal clear and clean, it may still contain contaminants that may make you sick if they are ingested.

When you are deciding on which water treatment solution you should get for your next trip, there are a few considerations you should keep in mind.

Filters versus Purifiers

The main difference between a water filter and a water purifier is the size of the microorganism each is trying to fight. A water filter strains out bacteria and protozoan cysts, while a water purifier can also help fight viruses that are too small for a filter to catch.

Many purifiers come with a cartridge or other internal element that is made of pores to help trap debris and other bacteria. As these elements are strained through the cartridge, the materials may begin to clog up these pores, so the internal cartridge will need to be regularly cleaned and replaced when needed.

Types of Purifiers

Gravity Based Water Purifier: These purifiers use pressure as the water travels from the higher chamber to the lower chamber while filtering out bacteria.

They do not require electricity to work, they are a relatively low cost and affordable way to purify water, the filters are low cost, and the device is easy to maintain, and they are portable and extremely easy to use. However, they cannot kill all various microorganisms and cannot filter heavy metals.

UV Water Purifier: These water purifiers use an ultraviolet purification technology to clean the water. The UV radiation is able to kill bacteria, germs, and viruses.

These purifiers do not have to use any chemicals so the water will taste the same and they are a cost effective and minimal maintenance water purification solution. However, this type of purifier does require electricity to operate and cannot remove any fluoride, arsenic, lead, or nitrates.
