Listen, I've tried all the filters...ALL of them. This brand is the best in business. Some brands, you can feel a film or something on the inside and end up feeling like you need to wipe it out. That's not sterile imo. But this brand, no worries at all. Best filter on amazon. Yes, they're more expensive than the rest...but do yourself and your body a favor, spend the extra. Your veins will thank you later. I wish I knew about these years ago. Now my fixings are clear, dye free, and clean. Better late then never! Safety first ya'll!

Doesn't get much better than this. You can get down to 0.20 micron afaik. Should be standard procedure For illegal drug use. Unfortunately they are way too expensive for the regular addict, obviously spending the money on the drugs instead.

The Semmerfeld sterile syringe filters are great. I ordered the 100-pack which is a great deal. I grow all sorts of plants and mushrooms and mushroom substrate must be sterile or it will grow molds and it also requires gas exchange. I thought these would work grear for contaminant-free gas exchange and they work perfectly. I place the substrate in a mason jar and place the sterile syringe filter in the lid for gas exchange and it works perfectly, no contamination. Highly recommended.

These sterile syringe filters are the real deal. Each one is individually packaged so that there is no need to worry about contaminating the rest of the batch. These are hydrophilic, meaning that these filters let water through them. These filters do a good job of adding an extra layer of protection.
