It is probably safe to say most filters do an excellant job of venting and reduction of smell.. when You are walking or maybe even sitting.. (wheel chair) however with high liquid output I can see the filter rendered useless. and laying down for bed... nope.. aint gunna work.. once the filter gets wet, whether showering, or poopping, that's it... game over..
Now these e-z vents are decent to help relieve the gas build up.. easy to install.. only thing is venting in public rest room, would mean u need your portable poop pori cause it does nothing to hide the smell. u might as well think of it as farting in an elevator. cough cough..
burping your bag referrs to opening the top end of it to relieve your gas. ( the click type mio sucks for that...) cant do that laying down and even with the e-z vent , u gotta do it standing up...not in bed. so there are pros and cons. but you will adjust.. whatever works for you..
I agree, dont eat after 8pm.. or eat anything you know is gunna wake you up in the middle of night in terms of gas and output.. but some folks cant control their output.. all they can do is catch in in the bag. now when I say control, everyone knows the marshmellow trick, right? food that binds you may help you get a good nights sleep.. then again so can a pill or pot.
wish there was a machine of sorts.. a suction machine with its own filter.. at bed side.... and a long tube to suck the smell out of the bag. .but who can sleep with this contraption? and suppose it creates a vacuum? tricky shit there folks.
so we got filters that help to a degree... and e-z vent purging valve.. there's the old purge at top of bag.. am I missing anything here??
