Building sciences research has shown that highly efficient filtration of the
outside air before it is delivered to the home is one of the best ways to
reduce the level of particles suspended in your home's air. FEATURES
80-90% Efficiency Designed to meet the air filtration efficiency criteria
required to gain points toward certification in the Leadership in Energy
and Environmental Design (LEEDs) Green Building rating system.

Airflow & Pressure Drop
Installation
Disconnect power to any appliances or fans to which you will
be connecting the FB6. Failure to do so may result in injury.
• Seal unused mounting holes with aluminum tape or adhesive to
prevent air leak
• Install the FB6 between your HRV or inline fan and your home's
ducting.
• Make sure access door is oriented so you can easily check the
filter and replace it when needed.
• Use aluminum tape or an adhesive to seal the ducts onto the
duct connections. Duct tape eventually fills with dust and loses its
adhesive.
• If cold air from the outside will pass through the FB6 and it is
located in a warm area, condensation may occur. Insulate the
cabinet if this is a concern in your installation.
• If warm, humid air will pass through the FB6 and it is located in a
cool air-conditioned area, condensation may occur inside the
cabinet. Insulate the cabinet if this is a concern in your
installation.
• Open the access panel and check that the filter is in place and any
packaging is removed.
Maintenance
Replace your filter every three (3) months. Adjust your maintenance
schedule based on how dirty the filter is when you replace it. If the inside
of the cabinet is dirty, wipe with a clean, damp cloth. Enter the date the
filter was installed then the date of each replacement filter. (See back
