Easy to Use and Working Great So Far
These filters are very easy to use and have worked well so far. They adhere nicely, allow proper airflow, and I havenโt had any contamination issues since using them. Everything has stayed clean and stable, which is exactly what I was hoping for. Iโm very happy with the quality and performance and would definitely purchase again.

Used for mushroom jars
These have worked great for making my mushroom spawn jars! Have only had one issue with one jar where the filter came off a bit but I think it was just old and needed to be replaced because I had used it multiple times before without any issues. Will purchase these again when the time comes.

Excellent for the money.
I use these patches on my mushroom culture jars.

Excellent filter
Excellent filters, not a single jar has become contaminated since switching to these. Just donโt touch the filter, you may push contaminants through.

Worth the money

Would buy again.
These stuck on great. So far so good and seem to work great even after pressure cooking in jars.

Game changer!!!! forget syringe filters
I got sick of syringe filters getting loose from rtv silicone on my liquid culture jars. I tried these and i will never go back. These are 100% the way to go for mycology liquid culture and grain jars. They keep contamination out!!!!! They hold up in the pressure cooker. No liquid leaks through them and they stick and stay stuck in place. If your debating between syringe filters or these trust me and others save time and money with these!!! Buy buy buy im a customer now for life. Thanks for an amazing product :) I hope the bigger ones for mono tubes come back in stock so i can order those too.Purchased in Canada ๐จ๐ฆ

Almost useless
They are too porous and the adhesive won't last beyond a single use. Use 4 layers of 3M micropore tape instead.
