The other week, I reviewed the Osto EZ-Vent product and had given it a very favorable review.  One of the only concerns with the EZ-Vent is that the gas which escapes it is at full-strength, since there is no filter to neutralize the odors.   One innovative company aims to find a solution to that problem by offering a small filter to add to the Osto EZ-Vent.

I’ve tried these filters and I offer up my review for them below.

KEM Enterprises, Inc., the makers of the Osto EZ-Vent, does not endorse nor are they affiliated with Flat-D or the filter in this review.

The Ostomy Vent Deodorizer, which is meant to be used as a continual filter for odor and gas elimination, is attached to the opening of the Osto EZ-Vent.  Installation was very simple, and the filter fit on snug.  The flap which would normally close the Osto EZ-Vent simply stays open (which is an annoyance).  I did notice that these filters don’t look like a professionally manufactured product intended for medical use, but rather, a crude DIY project. The looks don’t detract from the filter’s function, but it is noticeable.

That flap has nowhere to go.

That flap has nowhere to go.

Apart from neutralizing odors, one selling point of these filters is that is provides gas to escape continually, which prevents ballooning.  Unfortunately, the filter did neither for me – I noticed odors within five minutes of using the filter and within a half hour, I had to stop using it.  And the filter got clogged very easily, much like the built-in filters on most ostomy pouches.  I was sent two as samples and both were equally poor performers.

Nope. Nope. Nope.

Nope. Nope. Nope.

My testing ended there.  If these were the results in a relaxed environment, I couldn’t possibly imagine how they perform if I were actively moving around, laying or with my pouch horizontally.

At the time of this review (Dec 2013), a pack of Ostomy Vent Deodorizers (5 per pack) can be purchased for US$15.95.  This product is not sold in Canada, but can be shipped across the border from Flat-D Innovations, Inc.  You can ask if they can send you samples if you’d really like to try the product.


Unlike the Osto EZ-Vents themselves, I do not recommend this product.  Perhaps the Ostomy Vent Deodorizer would be ok for allowing gas to escape odor-free if someone had dry, formed stools (colostomies), but the fact that it wasn’t even neutralizing odors means that you might has well use the Osto EZ-Vent as intended and when needed.
