Frequently Asked Questions
Is MERV 8 enough for spring pollen?
Yes. MERV 8 filters capture the majority of common pollen and dust particles while maintaining airflow for most residential HVAC systems. For severe allergy sufferers, consult an HVAC technician before upgrading to a higher MERV rating.
How often should I change furnace filters during pollen season?
During heavy pollen periods, change MERV 8 pleated filters every 30–60 days. If pollen levels are moderate and the home has fewer contaminants, 60–90 days may be fine. Check the filter visually; if it looks loaded with dust or pollen, replace it.
What if the filter doesn’t fit perfectly in my slot?
Always measure the actual slot and compare to the filter's listed actual size. Small gaps can cause bypass and reduce effectiveness. If dimensions differ, look for the exact size required or use a properly sized adapter or metal filter housing to ensure a snug fit.
