Moisture Flow Soffit Vent System
Prevent Attic Mold and Moisture From Improper Bath Fan Venting
Moisture Flow Manufacturing is a New JerseyÂ based company thatÂ specializes in developing innovative products that focus on solving structural, environmental, and health problems caused by outdated construction products and practices. Our pipeline of products are industry firsts, promoting better building practices and sustainable solutions to common problems in the construction industry.
Our Soffit Vent prevents mold growth in the attic caused by improperly venting bath fans in the attic.Â It is also a viable alternative to venting through the roof or to a gable wall, which both have limitations and potentially negative effects on home and health.Â The Soffit Vent is code compliant under the International Code Council (ICC)and the International Residential Code (IRC).

To whom it may concern:
Reference: Testing the air flow of a bathroom exhaust fan system. Testing was to evaluate the air
flow of an exhaust fan connected to a roof vent and compare the performance of the fan when
connected to the Moisture Flow Soffit Vent.

Today, 10/14/18, I successfully installed the Moisture Flow Soffit Vent. The vent was attached to a
Panasonic bath fan, model number FV-11V05, serial number 702. The fan and soffit vent were attached
using a 4″ transition duct, insulated to an R-8, and is approximately 12′ in length. After installation, the
fan flow was measured using an Energy Conservatory DG-700 manometer and an Energy Conservatory
exhaust fan flow meter. This is industry standard equipment used to test fan flow and measure
pressure. The measured CFM of the bath fan connected to the soffit vent was 111-117.
It should be noted that fan flow was measured in the same bath fan when it was attached to a roof vent
termination. The same transition duct was used, the same equipment was used to test the fan flow, and
all other conditions were similar (same fan, same transition duct, same attic, similar weather âtesting
took place approximately six hours apart), if not identical, except for the termination point. The
measured CFM of the bath fan connected to the roof vent termination was 90-96 CFM.
The observed difference in fan flow is likely due to the soffit vent termination, by its very nature, being
the last component of a down flow system. The transition duct running from the bath fan to the soffit
vent is on a downward pitch, which helps the fan evacuate the exhausted air with more force. It should
also be noted that because of the way the bath fan is positioned in relation to the soffit, the transition
duct does a 180 degree turn directly out of the fan unit. This bend did not negatively impact the
performance of the bath fan.
I encourage any qualified individual or organization to independently verify my findings.
This video shows what NOT to do!!! Homeowners spend over $10 billion dollars annually on remediation caused by mold growth in attics from improperly vented bathroom exhaust fans. The annual healthcare costs associated with mold contamination and loss in business productivity due to employee sickness are more than half a trillion dollars. Domestic pets are also affected by mold contamination, with medical treatment ranging from $500 to over $2,000.
