Sawyer PointONE As A Gravity Filter

Sawyer PointONE gravity filter

The Sawyer PointONE is my new favorite water filter. Depending on water conditions, it can filter up to one millions gallons, and the flow rate beats the Sawyer Mini water filter hands down.

However wonderful the Sawyer PointONE water filter is, the user still has to either fill up a bag or water bottle, then attach the bag or bottle to the filter. Filling a water bottle with a small opening can be a pain, and sometimes an act in frustration. Rather than using the bag that was included with the Sawyer PointONE water filter, I bought a two liter platypus bag. One end of the platypus bag opens, and water is simply scooped up from the water source.

Think of the platypus bag as large heavy duty ziplock bag with a hose attachment. The bag can then be hung from a tree limb, or from the side of a tree. From there a plastic hose is attached, with the Sawyer PointONE water filter inline between the platypus bag and the water bottle.

How Good Does A LifeStraw Work?

LifeStraw Water Filter

Surely everyone has heard of a LifeStraw? It is a simple tube that is a water filter. Place the inlet into the water, then suck the water through the tube. Seems simple enough right? Almost too good to be true?

If something seems to god to be true it usually is, except for the LifeStraw.

Back in March of 2017 I decided to take the plunge and ordered a LifeStraw from Amazon. In April I took the LifeStraw on a hiking trip and gave it a test run.

First impressions were very good. It was just like pulling water through a straw. The water took a few seconds to get through the filter, but when it did, the flow was excellent.

Is Two Step Water Purification Needed?

Is two step water purification needed? This could be in the event of a collapse of society, or on a hiking / camping trip.

There is a common misconception about filtration and purification. Filtration removes bacteria, protozoa and cyst, but does nothing to viruses. Purification affects bacteria, protozoa, cyst and viruses. Purification can be by any means – UV light, filters that remove a virus, chemical treatment.. etc.

Most water filters on the market have a pore size of 0.1 microns. The CDC recommends a maximum pore size of 0.01 microns for viruses. If a purifier says it has a pore size of .1 or .2 microns, it is only a filter. A virus will slip through a .1 or .2 micron filter.
