Q: "Before I buy an EnviroSept furnace filter panel, I need some questions answered.
- Can this unit be used in a heat pump forced air unit?
- With a gas pack unit?
- Is there a reduction of air flow through the filter? How much?"
Answer: The answers to questions 1 and 2 is "yes." The answer to question 3: yes the air flow is reduced somewhat. A clean fiberglass filter has an airflow reduction of .05 and this restriction with the Envirosept panel is .20.
Please let us know the size of your current fiberglass filter so we can help you choose the correct unit. Thanks for your question.
Comments: The Envirosept comes in sizes to fit all HVAC units. Maintenance is minimal: polywool filters need changed every month for most homes. Once a year or so, the panel needs wiped off with a microfiber or lint-free cloth.
