Water Filters (Portable Type)
We're doing a review of 5 water filters that you can carry with you in a backpack or even in your pocket. As we have with the rest, we'll use the top reviews from Amazon using only reviews that have 100 or more reviews attached to them. These filter all claim that they eliminate over 99% of waterborne bacteria but will not filter out chemicals, heavy metals or viruses, and will not desalinate water, meaning they will not remove salt from sea water. Do your due diligence and read the reviews. Click on the picture or the underlined brand name, this will take you to Amazon for more information.
LifeStraw Personal Water Filter
This filter weighs only 2 oz. and is 9" x 1" x 1" in size. Compact enough to carry in a backpack, purse or tackle box. It uses a 0.2 micron filter.
The LifeStraw can filter up to 1,000 gal or 4,000 liters of water. There is nothing to replace, once you can't drink through it anymore, you discard it and purchase a new one. One LifeStraw would last the average person a lifetime.
Membrane Solutions Portable Water Filter
This filter weighs in at 4 oz and is 6.7" long and 1.1" wide.
The Membrane filter is a three stage filter system and can be taken apart and cleaned, but will filter approximately 1,000 liters of water.
Their pore size is 0.1 microns, filtering out very fine particles.
Sawyer PointOne Squeeze Water Filter
This is a different concept than the straw ones, you can attach this filter to a bladder, a water bottle or straight from the stream. It comes with a 16 oz collapsible bladder. You can order multiply bladders if you're planning any long journeys. This also uses the 0.1 micron filter system.
Using the Sawyer PointOne syringe you can clean the filter out for unlimited usage. It claims it is good for up to 100,000 gallons, if you keep the filter clean. Sounds like a life time to me.
Glacial Stream Water Straw
This water filter is more the size of a straw, 8" long and 3/8" in diameter and is a five stage filter system.
Once you start using the Glacial Water Straw, it's good for 6 months or 200 gallons of water, then it needs to be replaced. There is no cleaning this unit. It does not say what size microns it uses, but claims to take heavy metals out.
Can be used with bottles, glasses, cups or right from the creek.
Katadyn Befree Water Filter
This filter comes with a collapsible .6 liter bottle. The filter can also be screwed on to a regular water bottle. When collapsed, it only weighs 58 gr. making it super easy to pack around with you.
The Katadyn Befree uses a 0.1 micron filter, and will last up to 1,000 liters, then would need to be replaced.
