Filters are just tiny plastic pieces. You guys are so strong, it would be very easy to blow them out accidentally. The pressure you exert through the little filter and the speed that you apply the pressure both make a difference in how well your filter will work. Also, if you are filtering something with a lot of junk versus filtering out a 100% soluble alcar oral suspended in distilled water, you should have very little trouble and no blow out.
Different filter brands work differently. Each supplier probably offers a very basic PES 0.45 filter that fits nearly all applications. Some are better than others so some will probably blow out sooner..
We've got tiny 0.45 filters that seem to work well. No complaints yet. Also, a new vacuum driven filter to save your thumbs....
