Lifestraw Backflush adapter , water filter membrane bottle PET 2L straw PEAK

Lifestraw Peak STRAW adapter

for backflushing with a bottle

this filter is very strangely designed. the clean end only has a mouthpiece and no way to use a syringe or bottle in order to backflush it. the recommended way according to the manufacturer is to blow thru it with your mouth… no thank you. most if not all the other mainstream membrane filter in this format use a syringe or bottle to flow clean water thru in reverse, in order to cleanses it. this here simple print enable the user to do with that! in a convenient way. the thread is of the older model, big 2L pop bottle or smartwater brand water.

this is my 8th iteration and feature a conical seal. that is tailored to fit.

it is perfect fit using my printer (ender 3 se) and might require a tiny bit of resizing for you.
