At first glance, both 0.2 and 0.5 micron filters block them. The problem is real-world filter performance, not ideal conditions. Filters are rated for nominal particle retention, not absolute — meaning a 0.5-micron filter may allow smaller particles, deformed spores, and bacterial cells (0.2–2 microns) to pass under positive pressure during bag handling or gas exchange. A 0.2-micron filter provides a meaningful additional safety margin, particularly important during long colonisation runs in non-sterile environments, or when your ambient contamination pressure is high.\u003c\/p\u003e\n\u003cp style=\"font-size: 13px; color: #555; line-height: 1.7; margin: 0;\"\u003e\u003cstrong style=\"color: #1a1a18;\"\u003eAnd why thickness is a contamination issue, not just a durability one:\u003c\/strong\u003e Micro-tears in thin polypropylene — too small to see but large enough to bypass the filter — are one of the most common and least-diagnosed sources of post-sterilisation contamination. Extra wall thickness dramatically reduces the incidence of micro-tears during filling, handling and sterilisation. It’s not just about bags surviving the autoclave.
