Frequently Asked Questions
Will a MERV 13 filter harm my HVAC airflow?
When sized and installed properly, MERV 13 pleated filters are designed to balance particle capture and airflow. Choose the correct depth and ensure your blower motor is in good shape; deeper pleats often lower face velocity and reduce pressure drop compared with overloaded thin filters.
How often should I change a filter during smoky weeks?
During heavy smoke events check filters every 2–4 weeks and plan changes every 30–60 days if visibly loaded. Even if the filter is rated for 90 days, smoke loads fill media faster and reduce effectiveness and airflow.
My filter slot size seems off—what should I do?
Measure the actual opening where the filter slides in (not the nominal size on old filters). Many customers report small size variances; if you’re between sizes, pick the model listed for your HVAC or consult the unit manual. Some buyers trim minimal overhangs, but avoid forcing an oversized filter which can bend frames and create gaps.
