Frequently Asked Questions (FAQ)
1. How does a 20x20x1 MERV 8 air filter help prevent HVAC repairs?
MERV 8 filters capture dust, dirt, pollen, and pet dander before they enter your HVAC system. This keeps coils, blowers, and motors clean—reducing wear and tear, preventing airflow blockages, and helping you avoid breakdowns that lead to expensive repairs.
2. How often should I replace my 20x20x1 MERV 8 air filter?
We recommend replacing it every 90 days for most homes. If you have pets, allergies, or live in a dusty area, consider changing it every 60 days for optimal performance and protection.
3. Is MERV 8 the right rating for my home?
Yes—MERV 8 offers an ideal balance. It captures up to 90% of common household particles without restricting airflow, making it perfect for most residential HVAC systems. It's especially suitable for families with pets or mild allergies.
4. Can using a higher MERV rating filter cause HVAC problems?
Sometimes, yes. Filters with MERV 11 or higher can restrict airflow if your system isn’t designed for them. That added pressure can strain your blower motor. MERV 8 is considered a safe, effective choice for standard systems.
5. What happens if I forget to replace my air filter?
Over time, the filter clogs with debris. This restricts airflow, forces your system to work harder, and can cause overheating or component failure. It also leads to higher energy bills and poor indoor air quality. Routine replacements keep everything running efficiently.
