Based on our team's years of hands-on experience, we will take you through the exact steps we recommend, spell out the common errors we encounter, and reveal to you why a high-efficiency filter is not just a wise move—but crucial for your house's air quality and longevity of the HVAC system.

Detach the existing filter from the HVAC unit.
Verify system compatibility with the filter.

Our Advice:
Check the airflow arrow. Always point the arrow on the filter frame toward the blower motor or ductwork. This ensures air flows properly through the filter media.
Insert flush and snug. An improperly installed filter results in bypassing of unfiltered air. Check to see that your filter is tightly secured into the housing.
Choose the right efficiency. MERV 8 to MERV 13 filters would be the best options in terms of efficiency for most households, according to our recommendation. They provide the optimum air quality without compromising on the airflow through the system.
Replace regularly. Our analysis and feedback from customers suggest that changing the filter every 60 to 90 days keeps your HVAC system running efficiently year-round.
If you follow these simple but very important tips, you will not have to worry about dust, allergens, and HVAC inefficiencies being present in your home.
