filters showed a more
significant degradation of efficiency. MERV 14 filters degraded up to 6
MERV values depending upon the size of the bypass gap – that
MERV 14 can perform as low as MERV 8 levels. This has huge implications
for hospitals and other sensitive applications. The importance of
eliminating bypass with proper filter gasketing and examination of the
filter housing or framing system for bypass is paramount.
