MERV system
The MERV System (Minimum Efficiency Reporting Value) was instituted to provide
minimum efficiency values. When you first install your new filter, its efficiency
is at its lowest point. That's because it hasn't built up enough dust and particles
on the filter to help trap more dust and particles.
The MERV Rating will give you a worst-case scenario for the lowest amount
of efficiency you can expect from your filter. This MERV System also measures
the size of the particles a filter can trap. The scale that the MERV System uses
can range from a MERV 1 to a MERV 16 (95%+ ASHRAE filter). The MERV System is
an excellent tool when you know which contaminants you want to have filtered.
