If I am using a Self Cleaning hood with Captrate, how often should I wash the pre-filters, replace the high efficiency filters, replace the HEPA filter and replace the odor control?
This will be dependent on how well the hood is maintained. Pre-filters should probably be washed monthly depending on load. The high efficiency filters may last up to 2 months. The HEPA filters could last up to 6 months. The odor control filters are highly dependent upon load. Typical replacement times range from 1 to 2 months.
