Camping out means you'll be depending on the natural resources around you for hydration and cooking. But water at campgrounds is not always safe to drink; in fact, unless the campground has posted signs that the water is safe to drink, you need to take steps to purify your own drinking water. With a water filter, you can remove bacteria that can cause illnesses without having to boil your water first or use chemical tablets.
What to Buy: Water purification tablets are light and don't take up much space in the bag. Commonly made of chlorine dioxide, they kill most waterborne pathogens but require at least 30 minutes to fully purify the water. The colder or cloudier the water is, the longer the treatment takes.
If chemical treatment sounds scary to you, opt for water filters instead. There are a few types of filters to choose from. Bottle filters work like a coffee press. They have a cartridge inside the bottle to catch debris and bacteria, cleansing the water for safe consumption.
Squeeze filters are attached on top of bottles. The water is treated through the filter before leaving the bottle. Straw-style filters, meanwhile, work just like straws and allow you to drink directly from the source.
