What to Consider Before Buying the Etekcity Filter

Pollutants removed

Foldable water bag and syringeThe Etekcity water filter is capable of removing a wide range of organic and inorganic contaminants from most freshwater sources.

Its active carbon filter can trap most chemicals, including volatile organic compounds (VOCs), heavy metal irons, chlorine, and other dissolved chemicals.

A pre-filter and hollow fiber membrane trap waterborne bacteria and protozoa including giardia and also larger contaminants such as insects or dirt.

In summary:

  • Removes dissolved impurities and over 99% of waterborne bacteria and protozoa.
  • Removes heavy metal ions, insect contaminants, and chlorine.
  • Activated carbon filter traps volatile organic compounds and other dissolved chemicals.


Filter stages for etekcity portable filterThis portable water filter impresses with a three-stage filtration system consisting of a PP pre-filter (cotton) made from BPA-free materials, an active carbon filter, and a hollow fiber membrane.

The former usually stops larger debris from getting into the hydration pack or bottle. Then, the carbon filter traps most chemicals and inorganic substances.

Lastly, the membrane cleans the water from bacteria and protozoa. It won’t trap viruses, but it still works wonders considering its design and size.

We recommend to drink water from water bodies where is clearly a flow (does not need to have a high flow though). Water that sits steady is likely to have microbiological growth such as bacteria and potentially, viruses.

Operation and Maintenance

The Etekcity personal water filter is elementary to use. The package includes the straw-like filter, a syringe for collecting water from harder-to-reach spots and a foldable water bag for collection (for latter use) that attaches to the filter.

Regarding the pouch, simply fill it with untreated water and screw it onto the straw filter. To filter while you walk, attach the bag to your backpack and place the filter in a water bottle for clean water collection, then let gravity do the rest (yes, this could be also a gravity fed water filter such as the Alexapure Pro Water Filter).

Wash both the filter and its accessories with clean water when you return home; Etekcity has a lifespan of approximately 400 gallons or one (1) year.


  • If you are planning to use this portable water filter out in the cold weather, do not let the system freeze in order to keep the hollow filter still useful.
  • You can use a plastic water bottle (as long as you can screw the filter) instead of the foldable bag. This way, you can increase the pressure of the water and having a better flow rate.
