Has anyone used this? & did you leave the carbon in the filter? or did you take it out?
Im confused as i have read most people take their carbon out & i have read the back of the box says filterproof .... what do i do?

As stated on your other thread, take it out.

ive used it and it worked for me.

always take the carbon out when using any meds, regardless of what the box of the meds says usually.

you will find the carbon will absorb the medication, therefore needs to be taken out
