Best Portable Water Filter Reviews For 2021

Water is essential for human survival. Did you know that the US Environmental Protection Agency (EPA) found over 80 contaminants such as chlorine, e-Coli, and lead in water? That was in tap water. So just think about what is lurking in outdoor streams and standing ponds. As such, it is important to get yourself a water filter to ensure that the water you and your family drink is completely safe. Portable water filters are great when hiking, travelling or camping. They remove impurities in water by lowering the contamination using a fine physical barrier. You can turn that standing pond into a viable drinking water source in no time at all. This post will review the best portable water filter systems that you can find in the market.


How to Choose the Best Portable Water Filter

Types Of Water Filters

• A filtered water bottle is an ideal portable source of clean drinking water. This bottle has a built-in filter that purifies the water before it reaches your mouth.

• Water filter straw: It acts just like a straw, but the water is purified before it gets to your mouth.

• Pump-style water filter: This filter purifies water by using pressure and an array of filters. It cleans out the water quite effectively.


Things to consider

• Portability and weight: When you are choosing a water filter, you have to consider its portability. The ideal one should have a lightweight design and it should be easy to carry, especially if you love hiking and camping.

• Effectiveness: A portable water filter’s effectiveness is measured by its ability to clean drinking water. You should get a water filter that has the most functional filtration system, which can eliminate harmful bacteria and protozoa from the water.

• The cost: Before you venture into the market to get yourself a portable water filter, set a budget limit so that you can get yourself the ideal product at a reasonable price.

• The wait time: Water filters clean a particular volume of water after a specific time. Therefore, you should get yourself a water filter that has a minimal wait time. You can establish the wait time by looking at the product’s specifications.

• The filter medium: Different water filters have different filter materials. The effectiveness of each is greatly determined by the filter medium each has. There are ceramic filters, fiberglass filters, silica filters, and hollow fiber filters.

• Other factors to consider include the amount of water, the micron size, and maintenance needs of the portable water filter.
