Alright, let’s be real: mycology isn’t for the faint of heart, especially when it comes to keeping your cultures healthy. That’s where this hydrophobic membrane comes in like a breath of fresh air—literally.While I’m always making sure my culture jars have a filter patch for contamination-free ventilation, I needed something that would specifically help with air exchange without letting CO2 build up in the jar. This membrane is the answer. It lets air in without letting in any unwanted contaminants, so my cultures get the oxygen they need to grow strong and healthy.It’s a simple piece of the puzzle, but it makes a huge difference. With this membrane in place, I can focus on growing my cultures, knowing they’re getting the right balance of fresh air and protection. No more worrying about CO2 levels messing up my setup.If you’re growing mycology cultures and need to keep things ventilated just right, this membrane is a must. Five stars for helping my cultures breathe easy!

Purchased these to modify some grow tubs. The smaller ones work best for my tubs.If using the larger patches, less is more. Tried using 4 of the larger patches and it allows too much gas exchange and it's hard to keep humidity.

I used these to filter some gas exchange ports in a high humidity environment and they are doing a great job. There is a noticeable amount of gas and humidity exchange in an a radius around each filter. The adhesive is strong and bonded well with plastic. There is a circle cutout on the throw away backing that is probably useful for sanitizing the “clean side†of the filter prior to application, otherwise I don’t know why they’d go through the trouble to cut holes in it.

I love these! Very easy to use, made it through the pressure cooker at least 3 times so far, and still look good as new. I have made at least 20 mushroom jars with no contamination. Will be a repeat consumer of these.

Hat für mich super funktioniert. Die Filter kleben gut am Eimer welcher für die Pilzzucht verwendet wird. Und die Filterung/Belüftung hat gemacht was sie soll tolles Ergebniss.

Ich habe die hydrophobe PTFE-Membran für einen etwas unkonventionellen Einsatz genutzt und sie zur Abdichtung von Bohrlöchern an den Rückleuchten meines Ford Edge verwendet. Diese Löcher habe ich gebohrt, um Staunässe zu beseitigen, die sich in den Leuchten angesammelt hatte. Nachdem die Rückleuchten vollständig getrocknet waren, habe ich die Membran eingesetzt, um die Öffnungen abzudecken. Das Ergebnis: Die Membran lässt Luft zirkulieren, verhindert aber zuverlässig das Eindringen von Wasser.Das Produkt funktioniert einwandfrei und hält bereits seit mehreren Monaten perfekt – selbst bei wechselnden Wetterbedingungen. Eine clevere und äußerst praktische Lösung für Feuchtigkeitsprobleme. Absolute Empfehlung für ähnliche Einsatzzwecke oder als flexible Dichtlösung!
