If you have a VanEE or Venmar air exchanger, this genuine replacement filter (part #03096) is exactly what you need to keep your system running efficiently. The exact size of 12-7/8 x 11-3/4 x 3/4 inches ensures a perfect fit without gaps or compression issues. This filter is specifically designed for Venmar AVS and VanEE Air Exchanger models including the 1001 HRV and 1001 ERV units. Regular filter changes are crucial for maintaining good indoor air quality and ensuring your heat recovery ventilator or energy recovery ventilator works properly. A clean filter captures dust, pollen, and other particles while allowing optimal airflow through the system. This genuine VanEE part guarantees compatibility and performance that aftermarket filters sometimes can't match. Changing your filter regularly (typically every 6-12 months depending on usage) helps your system run more efficiently, reduces strain on the motor, and improves the air quality in your home. Installation is straightforward - just slide out the old filter and insert this new one in the same orientation. Sold as a single filter, it's smart to keep a spare on hand so you're always ready for the next change. Don't compromise your indoor air quality or system performance with generic filters - this genuine VanEE part ensures your air exchanger continues providing fresh, filtered air throughout your home.
