How To Pick A Portable Water Filter?
Included below are five of the main factors you need to check before deciding whether or not you should purchase a specific portable filter. Taking the following factors into consideration should make it easier for you to find the best portable water filter.
There are several types of portable water filters, but the ones you’ll likely encounter most are gravity, pump, squeeze, and straw-style filters.
Gravity filters are great because you don’t have to do that much work, but they can be slow. Pump filters will enable you to draw water even from shallower sources, but they tend to become tougher to work with as they age.
Squeeze filters are remarkably versatile, but many of them have to be paired with separate containers. The straw-style filters are very compact, but they aren’t ideal for producing a large amount of clean water.
To get an idea of how quickly the filter can provide clean water, you should take a look at its flow rate. The filters with higher flow rates are best if you want your thirst addressed as quickly as possible.
Portable water filters that eliminate as many contaminants as possible would obviously be best, but at the very least, look for ones that specifically target cryptosporidium and giardia. These are parasites that can cause diarrhea and must be avoided at all costs when you’re outdoors.
Check to see how many gallons of water the filter can handle before it needs to be replaced. You will be able to find filters that can process so much water that they should essentially last for a long time. You don’t necessarily have to aim for that, but filters that can go through 200 gallons of water are good to have.
If it’s a straw-style filter that you’re considering getting, you don’t have to worry as much about how many gallons it can process since they only work on small amounts of water whenever they’re used.
Ease of Use
The portable water filter should be your ally outdoors and not your enemy. If it takes a lot of energy to get the filter set up, it may not be worth using. Pick one up that you can use easily so that you can get water on demand.

Straw Filters also have their own disadvantages as well such as less thorough water filtering (some particles may still make it through), easy to clog and shorter lifespan.

Gravity Filters - As exactly as they sound, gravity filters use the force of gravity to push the water as it filters contaminants from the water. The untreated water is stored on a water reservoir and when it is needed, it passes through a water hose with a filter attached.
Pump Filters - Pump Filters require effort from the user in order to achieve clean water. The user forces the water through the filter by pumping. The clean water is then transferred onto a small storage tank.
