Energy Tip

Most filters are labeled with a MERV (Minimum Efficiency Reporting Value) rating number, which measures a filter's ability to trap particles ranging in size from 3.0 microns to 10.0 microns. Residential filters commonly have MERV ratings of 1-12. In most cases, a pleated filter with a MERV rating between 6 and 8 is adequate. Remember to clean or change your filters at least every two months during the heating season.
