What This Product Is
This replacement filter set is designed specifically for the Flexit L7X/S7X (VG700) heat recovery ventilation system. The set includes two high-efficiency filters that work together to clean both incoming supply air and extracted exhaust air. Available in the F7+F7 configuration, this set delivers premium filtration performance for residential and commercial installations where superior indoor air quality is required.
Filter Class Comparison
Understanding filter efficiency helps you choose the right set for your environment:
- M5 filters (ePM10 55%) capture medium-sized particles down to 10 micrometers, including larger dust and pollen
- F7 filters (ePM1 70%) capture ultra-fine particles down to 0.3 micrometers, including fine dust, bacteria, combustion particles, and smaller pollen fragments
- The F7+F7 configuration provides maximum protection in both airflow directions, ideal for urban environments, high-traffic areas, or homes with allergy sufferers
Choose the F7+F7 set when indoor air purity is your top priority and you want comprehensive protection against fine particulate matter.
