I'm seeking to disinfect a Platypus gravity water filter made with hollow fibers. My main concern is to address any mold / mildew that may have developed inside the hollow fiber filter due to long term storage.
The manufacturer suggests
"To disinfect your Platypus filtration system, fill it with a solution of unscented household bleach and water, using a concentration of 2-5 drops per liter of water. Close and swirl for 10 seconds. Leave filled overnight.
"Filter solution through any filters and/or hoses, then rinse system (including filters and hoses) three times with hot water. Let air dry.
"Note: for an eco-friendlier option, use a chlorine-free, hydrogen peroxide-based bleach alternative.
I called the customer hotline and asked if I could just pour in hydrogren peroxide from the pharmacy, but they said I should just stick to the recommended guidelines. The agent also reminded me that if I use chlorine bleach, it's best to use a fresh bottle. Do you think the same is true for hydrogen peroxide bleach?
Could I dilute 2-5 drops of the pharmacy 3% hydrogen peroxide with one L of water?
I looked at the Seventh Generation non-chlorine bleach MSDS, and it lists hydrogen peroxide at 3-5% concentration:
Any insights would be welcome. Thank you!
