Buy sterile filters. These are for peptides.
This is interesting, they swapped out all the PES single filters on Amazon to double layer. Ideally you'd just want a single layer. Single layers seem only available on their website now.
2 layers

Either way if you're doing it for the long run, it's better to just grab from the website, much cheaper.
