TIMBERLINE FILTER &
REPLACEMENT FILTER

The water filter for outdoor enthusiasts who enjoy  a drink of cold fresh water without a wait or a chemical taste.

This ultra-light unit provides protection against giardia, cryptosporidium and other organisms of equal size or larger such as ameba, tapeworm eggs, etc.

In areas where beaver or muskrat are prevalent, giardia is probably  the most common hazard in drinking water.  Outbreaks of giardiasis have occurred throughout the United States and it is a potential problem for most outdoor people.

The Timberline Filter is the most versatile and rugged system for providing giardia-free fresh water to outdoor people in pristine areas.

INSTRUCTIONS FOR USE

With a Pump:

1.  Press fit 2' tubing into the tapered hole in the top of the pump.
2.  Press fit pump onto top of filter.
3.  Immerse the filter in the water to be filtered and the end of the 2' tubing into container for purified water.
4.  Pull the plunger on the pump up, pulling water up through the filter.  Push down on the plunger forcing water through the tubing and into the container.

Continue the above action until the desired amount of water has be filtered.  Pumping rate should not exceed 1 quart in 1.5 minutes (a comfortable rate).
5.  Vertical operation of the pump is preferred so that the ball check valves operate properly.

With a Straw:

1.  Remove 1 1/2" tube from filter.
2.  Attached furnished 6" tube to outlet on the topside of the filter.
3.  Immerse the filter in a container of stream water and drink through the tube the same way you would a straw.

The Timberline Filter has a capacity of up to 50 gallons with a  flowrate of 1 quart per minute (depending on the clarity of the water filtered).

Eventually the filter will plug off to the point where the pressure drop will be excessive (inconvenient--slow filtration).  Replacement filters are available to provide continued use of your system.

TESTING

The Timberline Filter design has been tested at Colorado State University by Dr. Charles Hibler for efficiency in removing giardia cysts.  Several individual filters were challenged with water containing several hundred thousand giardia cysts.  NO giardia cysts passed through the Timberline Filters.  The detection procedure was such that a SINGLE CYST would have been detected if it had been present.

FEATURES

  • Filters particles and micro-organisms down to a nominal 1 micron level

  • Virtually unbreakable

  • Lightweight (6 oz.)

  • Does not affect water taste

  • Has been thoroughly tested for giardia removal

  • Can be used with a straw or pump

SELECTION OF WATER SOURCE

You will achieve better performance and longer life when using the filter at the clearest source.  If muddy water must be used, then settling and / or prefiltration through a coffee filter is recommended.  When muddy water is used, the user should be prepared for substantial reduction of filtration capacity.

Even with apparently clear water, filter life will be extended by presettling (even a few minutes) or pre-filtering with a coffee filter.  This is particularly true with rushing alpine streams which typically carry surprising amounts of sediment and debris.  When going on extended trips it is suggested that a backup replacement filter be included in your supplies.

The Timberline filter removes the parasites such as giardia, ameba, cryptosporidium, etc. but does not protect against bacteria or viruses.  Therefore, water containing substantial amounts of fecal matter or effluent from sewage treatment facilities (including septic tanks) should be avoided.

The filter and housing are factory assembled and should not be taken apart.  At each end of the filter element, there is a hot melt seal, which accommodates minor dimensional variations and prevents bypassing of the filter element.

STORAGE

Frequent use of the filter prevents substantial buildup of micro-organisms in the filter media.  When the filter is not in use, flush the filter element with either diluted bleach (1 tsp. household bleach per gallon of water) or distilled vinegar (2 tbs. per cup of water) and place into a plastic bag.  Keep it in the refrigerator.  Both of these solutions can easily be flushed out of the filter with fresh water prior to use.  This approach is satisfactory for short term storage (weeks) and will prolong the life of the filter.

If the filter is to be stored for more than two months, the filter element should be dried.  Flush the unit with distilled vinegar (2 tbs. per cup of water).  Remove the excess vinegar and water by using the 12" adapter tube with the pump.  Insert one end into the pump head and the other into the top of the filter after removing the short tube from the filter.  Pump air through the filter until fluid ceases to flow out of the filter media.  Allow filter element to dry in a warm place for 5-7 days.

HELPFUL HINTS

  • When pumping large quantities of water it is easier to pump from a container rather than directly from the stream.


  • To ensure a good tubing connection, hold the pump head and to tubing together in one hand.


  • When the tube connection, at the pump, becomes loose; trim tube 1/2".
