    What to look for when buying a water filter

    When buying a water filter, you will notice that each choice comes with a host of unique features and styles. It can be tough to narrow down which one is right for you. This section will go over the most important features that you should look for when investing in a water filter.


    When buying a water filter it is crucial to see what type of filter it has and if it will filter out your kind of bacteria and sediment. Before buying a filter, check what kind of things you need to be filtered out. If you need to drink out of a muddy pond, try to find an option with a reliable sediment filter. If you need to filter out microorganisms and certain types of bacteria, make sure you get a thorough bacteria filter. It is important to know what situation you will use it in. The PortaWell is a great option if you are concerned about filtering. It goes through many different filters so that your water can be cleaner than clean. It is also electric powered so it is practically instantaneous.


    Weight is also a big thing to consider. Most filters don’t weigh more than 20 lbs. But that is a lot of weight if you are carrying it in a backpack. Again consider how you would use it. The Katadyn is a great option because of how portable it is. You can fit it in your pocket and have clean water anywhere. But also consider that a filter that small may not filter out everything that you want. Or if you just want a stable filter for your bug out kit, it would probably be worth it to invest in a bigger model with more filters. 


    When you’re in an emergency situation, whether it be natural or man-made, the last thing you want to worry about is how to access clean water. Luckily there are some great options available for portable water filters that can purify almost any source of water and have long lasting parts.
