Finding the perfect fit filter isn't easy when most manufacturers only offer a handful of standard sizes - rounded to nominal dimensions. Exact Filters® are high quality perfect fit Furnace, AC and HVAC filters made with only a 1/8" +/- manufacturing tolerance. Exact Filters® are made to your exact size ensuring no dirty air is bypassing your filter and into your system.
Choose between basic filters with a MERV 4 rating to capture dust, protect your system and allow your blower to maximize airflow. If indoor air quality is a concern choose from a pleated filter option starting with a MERV 8 rating, MERV 11 or our very best MERV 13 rated filters.
Be sure you have taken the true exact measurements of your current filter.
