I have been experimenting with a DIY gravity filter using the filter cartridge from my PUR hiker. The gravity filter works well but I have noticed that my filtered water has a musty taste and it seems to be coming from the filter cartridge. I clean the filter every time that I use it, and recently took it on a 3 day outing and I did not get the musty taste in my water.
I used the instructions on BPL to make my gravity filter and Captain Jac says:
Doesn't bleach effect the activated carbon inside the filter cartridge?After a trip I remove the cartridge from the bag and wash the bag with clean water. The tubing and cartridge are washed in a 10% bleach solution and allowed to sit in the mixture about 30 minutes.
What's the best way to sanitized and clean the filter cartridge?
