Frequently Asked Questions
Is MERV 13 overkill for summer smoke and pollen?
No — MERV 13 is the recommended sweet spot for smoke and pollen because it captures fine particles (including many PM2.5 and pollen sizes) without the high airflow penalties of some higher-MERV filters. Ensure your HVAC system can handle a denser filter; older or low-powered systems may need professional advice.
How often should I change a MERV 13 filter during wildfire season?
Change frequency depends on smoke concentration: during heavy smoke, check the filter every 2–4 weeks and expect to replace it every 30–60 days. Under light seasonal pollen or normal summer use, 60–90 days is typical. A visibly loaded or discolored filter means it's time to replace it.
Will using a MERV 13 filter reduce my HVAC performance or raise bills?
A correctly sized and installed MERV 13 filter usually has a small impact on efficiency. However, if the filter is undersized, clogged, or your system is weak, you may see reduced airflow and higher run times. Keep to recommended replacement intervals and confirm the filter's actual dimensions match your slot.
