Frequently Asked Questions
What MERV rating is best for spring pollen without hurting HVAC performance?
For most homes, MERV 8 offers a good balance of pollen capture and low pressure drop. MERV 11 increases capture for heavy pollen loads; MERV 13 provides more filtration but can add strain — only use MERV 13 if your HVAC's blower and manufacturer allow it.
How often should I change my furnace filter during pollen season?
Check filters every 30–60 days during peak pollen. If you have pets, high dust, or severe allergies, change monthly. Filters with higher MERVs may load faster and need more frequent replacement.
Will using a higher-MERV filter damage my furnace?
Not inherently, but higher-MERV filters increase resistance. If your blower motor is older or the system is not designed for denser media, higher-MERV filters can reduce airflow and efficiency. Consult your HVAC manual or a technician before switching to MERV 13 or higher.
How do I ensure the filter fits and doesn't leak around the edges?
Measure the nominal and actual dimensions of your filter slot and compare to the product's actual size. Choose filters with a secure frame and ensure the arrow points toward the furnace blower. If you notice gaps, use the correct nominal size or consider a slightly thicker/rigid-framed option for a snug fit.
