It is probably safe to say most filters do an excellent job of venting and reducing smell.. when you are walking or maybe even sitting.. (wheelchair) however with high liquid output I can see the filter rendered useless. And laying down for bed... nope.. ain't gonna work.. once the filter gets wet, whether showering, or pooping, 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 restroom, would mean you need your portable poop pori cause it does nothing to hide the smell. You might as well think of it as farting in an elevator. Cough cough..
Burping your bag refers to opening the top end of it to relieve your gas. (The click type mio sucks for that...) Can't do that laying down and even with the e-z vent, you gotta do it standing up...not in bed. So there are pros and cons. But you will adjust.. whatever works for you..
I agree, don't eat after 8pm.. or eat anything you know is gonna wake you up in the middle of the night in terms of gas and output.. but some folks can't control their output.. all they can do is catch it in the bag. Now when I say control, everyone knows the marshmallow trick, right? Food that binds you may help you get a good night's sleep.. then again so can a pill or pot.
Wish there was a machine of sorts.. a suction machine with its own filter.. at bedside.... 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??
