Quick facts
The MERV 13 filter box fits into a 6 in round duct, most often on the fresh air intake of an air exchanger. Outdoor air passes through a MERV 13 filter before entering the unit, then the house.
An air exchanger brings in outdoor air, along with what it carries
An HRV or ERV renews the air in the house continuously. That is its purpose, but outdoor air carries pollen, construction dust, traffic particles and, some summers, wildfire smoke. The exchanger’s original filter mainly protects the unit; a MERV 13 filter box adds finer filtration on the air you breathe.
What MERV 13 means
MERV is the filter efficiency scale defined by the ASHRAE 52.2 standard. The higher the value, the more fine particles the filter captures. MERV 13 sits near the top of the scale for residential use.
Installing it properly
- On the fresh air duct, between the outdoor hood and the exchanger.
- In an open spot, so the filter is easy to replace.
- With a check of the exchanger’s balancing after installation, since the filter adds resistance.
Replace the filter regularly: when clogged, it reduces the fresh air intake.
