Frequently Asked Questions
How often should I replace a pleated furnace filter in summer?
Replace MERV 13 pleated filters every 60–90 days for typical summer use. If you have pets, live in a high-pollen region, or experience smoke from wildfires, check monthly and replace sooner if the filter looks heavily loaded.
Will a MERV 13 filter reduce my AC efficiency?
A properly sized MERV 13 pleated filter is designed to balance particle capture with airflow. It should not materially reduce AC efficiency if the filter fits correctly and is changed regularly; an overloaded or wrongly sized filter increases strain on the system.
What if the filter dimensions don't match my slot exactly?
Always use the product's listed actual size (not just nominal size) to match your slot. If a filter is slightly small, you risk bypass and leakage; if slightly large, it may be hard to seat. Measure the opening and choose the closest actual-size option or consult your HVAC spec for acceptable tolerances.
