Hi Sunny! I hope you are doing ! I've been meaning to email you, but life got a little hectic, and now I'm out of town visiting family. At the very least I'll respond to your questions here now, and will write more when I get back home if I don't have time before then.
1. I change my wafer once a week...on Friday mornings. There have been times where it doesn't last a week and a few times I have made it to 9 days. As long as it feels secure and your skin doesn't seem bothered, I don't see any reason to keep the wafer on as long as it will last for you. I do know some people like to change to a fresh bag after 3 or 4 days, even if they aren't changing the wafer. I have never done this because my bags hold up well enough, and I use a different one when sleeping anyway. (The oversized one we've talked about
before)
2. Sometimes I use my hands to press down the wafer, but sometime I don't have time. I have used the hairdryer quite a few times and that works well too. You don't need to press down as hard since the heat helps activate the adhesive a bit. I also try to press down right around my stoma...to make sure the seal there is good and tight, since that is where the most liquid/wafer contact happens.
3. The filters are useless! As far as I know, there is no way to unclog them once they stop working because moisture is a big part of what makes them stop working to begin with. I think we use the same type of Convatec bags, and if so, they don't come in a non-filter version. But, there is another bag that is similar and it does come without a filter. know that wouldn't solve your problem, but at least there isn't a clogged and possibly leaky filter to deal with.
