Is your Lifestraw membrane microfilter floppy or stable in the cap?

Going on memory, in a previous post about the LifeStraw carbon filter Dr. F said if the carbon filter is after the regular filter it should not grow NTM. It’s filtering the water after it’s been through the Main filter.
In the table top dispenser that is how it is. I believe someone said the water pitcher was the same way.
There were no replies when I added this, so sorry for the duplicate. I can’t find a delete button!

I’m hoping that maybe Lifestraw’s pitcher has a better carbon filter that isn’t subject to the NTM growth. I emailed the company and I am waiting for a reply. I will probably change the filter monthly instead of every two months

I don’t think it’s about if it’s a “good” carbon. NTM will just thrive in any carbon filters them apparently.

I saw somewhere on some thread Dr F mentioned changing Lifestraw carbon filter every 3 weeks, But im not sure why we would need to since lifestraws carbon is AFTER microfilter and thus shouldn’t have much or any NTM ?
On the other hand, RO carbons are before the 0.001 filter so those carbon filters will have NTM and must be changed but HOW often? Anyone know?

THIS begs the question do we need to change Lifestraws microfilter MORE OFTEN than company says to for non-NTM/BE people? Because that filter definitely would have the NTM. Oy

Thank you for passing this info along. Now I am very frustrated since I thought I had resolved the “safe water” issue by purchasing my lifestraw pitcher. I just don’t know what to do next. Seems like for every step i take forward i am taking two steps back

I don’t see an option to order replacement membrane for the Lifestraw pitcher on the website

I went to their website and sent them a message. I believe it’s: info@lifestraw.com I just asked them to change my subscription from every other month to monthly. They sent me a confirmation to my email.
To just order filters without a subscription they do list them on their website. Just hit “shop now”

I believe that Dr. Falkinham addressed this concern. He explained that the water first goes through the 0.2 micron filter and then passes through the lower carbon filter. Therefore, the NTM is filtered out of the water before it reaches the carbon filter. You should feel safe when using the Lifestraw pitcher, but you do still need to disassemble it periodically and thoroughly clean inside, placing the filters to the side while you do this. I usually place mine on paper towels, add Dawn to the main pitcher reservoir along with very hot water (tap), thoroughly wash, then rinse and dry with paper towels.

I believe that, realistically, we will never be free of any and all bacteria in our environment, but the goal is to reduce exposure as much as possible.

What do you think of the option of not using the carbon filter since it sits on the bottom, thereby eliminating the problem of possible MAC build-up in the filter and needing to replace?
