643Re: [BackpackGearTest] PUR water filter information...
- Jan 15, 2001Following is an E-mail I received from PUR on January 6.========Subject: Message from PUR Outdoor ProductsThanks for contacting PUR.I can certainly understand your frustration. We feel it here, too. Please
understand that the recommendation being made about the use of the purifiers is
geared toward the worst possible conditions under which you would use the
purifier. In most conditions, virus kill is immediate when they come in contact
with iodine. The only situation when this is not the case is when the water you
want to filter meets ALL THREE of these conditions: Heavily contaminated water,
extremely cold water (around 32 degrees F), and water with a high pH level. If
you're reasonably certain that the water you're filtering does not meet these
conditions, you'll be just fine using a single pass with out the Stop Top. We're
confident the purifier filters meet or exceed the claims. No changes are being
made to the filters themselves. We're simply advising an extra measure of
precaution and common sense until the EPA gives its approval.
I hope this helps you make more sense of the issue. If you have additional
questions, please drop me a line anytime.

This is to advise you of a potential problem with the Stop Top
accessory Stop Top Cartridge that comes packaged with the PUR Voyageur,
Scout and Explorer water purifiers.
The Stop Top serves as a water bottle adaptor plus reduces the iodine
taste that may result from the purification process. However, recent
testing has revealed variations in the carbon used in the Stop Top which
could interfere with the purifier's ability to kill viruses in outdoor
(untreated) water. Tests showed effectiveness against cysts and
Purifier update kits will be available within the next few weeks.
Consumers can receive a FREE kit by calling Recovery Engineering, Inc.
In the meantime, consumers who already own PUR camping purifiers can
still use them. In order to ensure full anti-virus efficacy, we advise
you to remove the StopTop and follow use instructions for "How To Handle
Difficult or Extreme Water Conditions" located in your Use and Care
Briefly, the process involves the following four steps:
1. Disconnect the StopTop carbon filter and pump water into a temporary
container at a rate of less than 10 strokes per minute.
2. Remove the inlet hose from the water source and pump the purifier
until air comes out of the output hose.
3. Place the inlet hose into the temporary container and pump water
into your water bottle or
canteen at a rate of less than 10 strokes/minute.
4. Let the water stand for 20-minutes before consumption.
We are sorry for this inconvenience, but want to make sure that you
achieve desired performance from your purifier.
