Goodman ATUF374316 Air Filter
It is suggested that the air filter is changed every 3 months for optimal air quality through the ducts. The height, length and width of the filter is not a personal choice but rather a requirement of the manufacturer of your system. Air Filters are available in many filtering levels, depending on your air quality needs and air handler size requirements.
Key indicators that my main filter really needs to be replaced?
- The system air filter looks dusty and perhaps should be replaced now
- Manufacturers have recommended to replace your air filter every 90 days to assist in keeping the indoor air clean and fresh
- When you hold it up, the light will not show through the air filter
