I've had this happen, but usually after 7+ days, and not always. More so on the "improved" thinner Hollister bags.

How long until you notice this smell from the bag (not the filter)? 

@veganostomy glad to know I wasn’t having a moment! It was a little over 24 hours. Not a good sign for an “improved” product!

that happens from time to time.  thin plastic film like that is porous, it normally takes me 4-5 days to have a stinky bag,  but sometimes it has happened in a day.  filters work and sometimes i have to put tape over the vent hole right away.     they're mass produced, some errors go un-noticed.     be happy bags aren't made of thick rubber anymore.   

Lately I’ve had it happen as early as 3 days but as long as 4-5 days but since Most of the time until recently I was house bound I’d leave it until it bothered me ironically my spouse never noticed. Thank god for incense!!! By day 7 I just change it

That's a little discouraging. Hopefully, it was only a "one-off" thing, and that doesn't happen again. 

It may be helpful to use a trusted pouch deodorant, since it could delay or prevent any smells from getting through the plastic.

I've always been a fan of Hollister M9, which isn't scented, but it stops the stink from within the bag.

Well, I called Edgepark and they will not let me return the Hollister product which I figured.  Because the box was opened.  This makes sense.  It is just too bad they wouldn't take them back as defective.

I am going to see if there is a place they can be donated in Austin because it just feels wrong to toss them out. 

The Coloplast Mio bags aren't giving me any of that stinky trouble at all.  

I've had this happen with my 2 piece system. Every time, it's been that there tiniest little space that I had not quite got snapped down all the way. Since I rinse my drainable bags with a bidet, it becomes obvious really fast when I have water squirting out the bag/flange junction!

Give Hollister a call :) They're more likely to send replacements for something like that, plus, they should be getting feedback about their products so they can make them better.

I wouldn't expect them to, since the plastic used is thicker, and Mio's have multiple layers. I think the problem with the Hollister bags is that they've made them so thin (recent "improvement" within the last two years), and it's just not as good as the older bags. 

elle d.  .... This is NOT all in your head. I was told yesterday when I called Hollister about an issue getting M9 in my area & being told a basic lie by a certain supplier.  Prompting my phone call to Hollister & after 6 phone calls, 3 hours on hold  & 4 days waiting for an un- rec'd call back & unable to land even 1 Bottle of the liquid Blue gold in my surrounding & local area . 

I finally asked google for M9 suppliers in Canada. I chose to start far away and out of Ontario I've ordered a box of 12 bottles and if they don't expire I may well order another 12 next month and the next and the next and and and....! Lolol!   

This brings me to the stinky bag situation. UGH!  My biggest issue when I  1st became an Ostomate was  feeling that I had a cloud of stink around me much like Linus from Charlie Brown. Lol!  

As a new ostomate, a new widow with kids at home, 3 dogs 2 cats & no paycheck what money I had went to food, rent & bills & ICBC car insurance. 

What I learned here about Osto EZ Vents & M9 was that I needed to those 2 products & with what I could scrimp together to purchase I ordered one bottle & one pkge of the vents. I could not believe the difference both products  made in my life!! I instantly knew I never wanted to be without them.     

At any rate, I have been happy with the Hollister Pouches & even tried various types of them finally settling on the one piece  "Hollister 8331 "  pouch. It worked wonders for me right untill I started noticing subtle changes in products here & there but more so  within the past 14 months.   A few had been previously mentioned in other forums here.

YES, I too find them way stinkier much earlier then before.  In my experiences there ARE changes in the product making the bags so much harder to wear DUE TO INCREASED SEEPING OF ODOR, I can't wear a pouch now for more then 3 days max when I could go as long as 7 to 9 days before a need to change a pouch but now & with big noticable odor seeping thru by the 2nd morning of wearing them. Prompting changes on the 3rd or morning of the 4th day or sooner depending on whom I may be in contact with &  how closely.  

Yes, I notice that the charcoal filters  clog within 12 hours easily.  I noticed some time ago & likely one of the 1st things I noticed was that the filters leaking by the 2nd or 3rd day too. That little paper starts to go around the edges then its a full on leak causing further ODOR ISSUES and the need for taping with a piece of C-Shaped elasticity tapes over the filter. No, my pants or weight have not changed.

I also notice that the wafers are developing cracks from the stoma hole across about a 1/3 or less of the wafer. I'm doing or eating & drinking nothing different then before and cutting the hole with an ongoing cut no snipping involved.  

Back to the search for M9 . . . I have been without it for 2 weeks now and am anxiously awaiting an order delivery hopefully SOONER then later! 

This doesn't change things with the Hollister product.   I honestly do not ever remember being this stinky even  before the M9.  These past 2 weeks without the M9 have been none less then humiliating & highly embarassing for me.

You see, the other day my now almost 3 year old grand-daughter would not even sit on my knee on Day TWO of a new pouch & that was WITH my last 20 drops of M9 in the bag & the filter taped over.   When she got off my knee she turned & said  ""Munga fart!!"" All while holding her cute little nose!!  UGH! (And Yes, that sweet child calls me "Munga" of all things.) 

So, a lengthy phone call to Hollister to ask about the M9 they said along the lines that there was "no shortage",  as they make the product and theres lots of it available! SO, lets be even more honest,  I figure the suppliers are likely just not dealing with restocking shelves the way they used to as many companies are short staff due to Covid 19 rules and regulations in the work force.

So, now what???? I think I too will be switching to another company as we CAN'T seem to get straight ANSWERS &  HONESTY from Hollister.   I'm so done with these pouches I don't think I can even give away the ones I have here with osto e z vents on them. I'll  likely use them for a one day wear,  like for a scope or a swim.

For those of you not yet experiencing these issues & I hope you don't have to!  It could just be your supplier hasn't started with Hollister "new stock" yet. My sincerest  appologies for the length of this & for my rant !
