Are you an outdoor person? Do you like going on a hiking or camping adventure? If so, then you need to always bring with you a personal water filter. In case of emergencies in the wild, you can use your water filter to drink from any untreated water source or fill your water bottle with newly filtered water. Water is vital to keep you hydrated, and your water bottle is not enough to keep you hydrated for your adventure. There will always be a need to get more water, and often the source is unclean. Thankfully, water filters are here.

Quick buying guide

When you are ready to buy your own personal water filter, you must look into important factors of the product.

  • Brand – always make a selection from the top brands that manufacture water filters. They are top-rated for a reason.
  • Price – never buy a cheap water filter, unless the price is very low due to a promotion or discount. Cheap water filters are not reliable during your outdoor activity.
  • Portability – choose a product that is lightweight and easy to store. You will be carrying a lot of items in your hiking backpack, and it is important to keep everything light.
  • Durability – you can tell if the water filter is extremely durable through its physical attributes. But more importantly, you will know if the manufacturer is confident with the resilience of their product through the given warranty. If a personal water filter has a warranty of one year, then that means they are expecting the product to perform well for a year.
  • Design – of course, you need to consider your personal taste in choosing a water filter. Choose the one that fits your filtering needs, as well as the aesthetics.
