How often should I clean my HRV filters?
Clean or check your HRV filters every 3 months under normal conditions. If you have pets or live in a dusty environment, monthly checks are recommended.
Can I run my HRV with dirty filters?
While the system may continue to operate, dirty filters reduce efficiency, increase energy costs, and can strain the motors. Clean filters promptly when the E01 code appears.
Do I need to replace filters or can I clean them?
Most HRV filters are reusable and can be cleaned. However, filters should be replaced annually or when they show signs of wear or damage.
