Choosing an HVAC Air Filter for Allergy Concerns

Filtration can reduce some airborne particles, but the right rating must still match the HVAC system.

Consider MERV 11 or MERV 13

MERV 11 is a common balanced choice for many households. MERV 13 can capture smaller particles more effectively, but not every residential system is designed for the added resistance.

Confirm system support

Check your equipment manual, filter cabinet label, or ask a qualified HVAC technician before moving to a higher MERV rating.

Use multiple strategies

Keep windows closed during high-pollen periods, vacuum with appropriate filtration, wash bedding, and address indoor moisture. An HVAC filter is one part of a broader indoor-air plan.

Replace on time

A loaded filter may reduce airflow. Inspect it regularly, especially during peak allergy seasons.
