I use these for placing filters on mason jar lids for doing liquid mushroom spawn and for grain spawn jars.I have used a couple of dozen filters so far. I have had no issues. They jars / lids / filters do go through a pressure cooker. Depending on the whether I'm doing liquid culture or a grain spawn, that means either 30 or 90 minutes at 15 psi. There hasn't been any degradation and there are a few lids / filters that I've used 4 times and they've kept their integrity.Just one warning in regard to using this or any other syringe filter for this purpose: make sure you put a piece of aluminum foil loosely over the lid and filter combo. This is to prevent condensation during cool-down in the pressure cooker from dripping into the filter and possibly restricting air flow.

Utilizing these for my mycology hobby. Where sterile work is absolutely critical for success. These were incredibly easy to work with. I installed them extremely fast and have ran them multiple times through my pressure cooker with zero issues. Great product! Important to keep in mind, if using in a pressure cooker to cover the top of the container with foil to prevent the filter from getting wet. Recommended!!

I liked Everything about it. The quickness of delivery and it’s performance

I use this product for making a small batches of natural perfume from essential oil’s. I’ve been doing this for nine years and I have used thousands of these types of filters for this purpose. I’ve tried several different brands and I’ve never had an issue until I used this one. I could not get one filter to work properly. In fact I had to push the liquid through the filter instead of being able to draw the liquid through as it is supposed to be. So now of course because of this there is much more of a chance of cross-contamination because I have to use a separate container to put the liquid in. When I researched this company on Google and looked at the reviews on this product, I saw many of the same complaints. Because of this issue, I only feel comfortable making home batches and cannot sell these to the public as I will not take a chance in selling a sub par product that could be contaminated, so not only am I out the money for the filters, but I am out the money that I could be making while I’m waiting for new filters to come in from another company.

No manufacture defects. No infections to cultures. Would recommend.

Great product. Worked as described. I’m using this as part of the lid for my liquid culture jars to grow mushrooms.
