The Impact of Neglect Ignoring filter replacement carries significant risks that extend beyond mere inconvenience. High-efficiency models exceeding MERV 13 are available but may cause strain on older systems, so consulting the furnace manual is essential before upgrading.
Understanding Oil Furnace Filter Replacement Cost: Factors and Savings
Filter Type MERV Rating Average Cost Best For. Additionally, a noticeable decrease in airflow from the vents or an increase in dust accumulation on surfaces are clear signs that the filter is no longer performing its duty.
For improved air quality, pleated filters offer MERV ratings between 8 and 13, trapping smaller irritants without restricting airflow. Conversely, a rural home with minimal traffic and no pets might extend the life of the filter to the upper end of that range.
Understanding Oil Furnace Filter Replacement Cost Factors
Filters are rated using the MERV (Minimum Efficiency Reporting Value) scale, which ranges from 1 to 20. A sudden spike in energy bills without a corresponding change in weather is a common red flag, as the system compensates for blocked airflow.
