As most of you know, I am sometimes sent outdoor health equipment and supplies to evaluate. I’ve recently received a few items worthy of mention.

Sawyer Squeeze Water Filtration SystemFirst, there is the Sawyer Products ‘Squeeze’ Water Filtration System. Advertised to be able to endure filtering 1 million gallons of water for the purpose of water disinfection/purification, this 0.1 micron filter is rated to be able to remove sediment, bacteria, protozoa, and cysts from water. It uses an in-line series of a bag (to contain the unfiltered water: 3 bags are supplied in sizes of one each at 32 ounces, 16 ounces, and 12 ounces) connected to a filter that simply screws onto a fitting at one end of the bag. The water is then squeezed through the hollow fiber-containing filter and exits the system through a discharge port similar to the pop-up closure top found on many water bottles, such as those used by cyclists.
It is easy to use, extremely lightweight, and convenient to pack and carry. The kit comes with a 60 milliliter syringe to be used to backwash (clean) the filter should it become less efficient, because it is becoming clogged with whatever has been removed from the water by the unit. You can learn more about this product and others from Sawyer Products at www.sawyer.com.
