Good price for a basic filter. My HVAC is older and doesn't have the capacity for a higher rated, more expensive filter, and a filter of the same rating costs significantly more at the big brick and mortar stores. The MERV rating works for what I need, as a much higher rated filter will reduce the already low airflow in my home to near zero, and a lower rated filter will simply let in too many allergen-causing particles. That's the balance my HVAC needs, though not what my allergies deserve, so I use air purifiers throughout the house to keep the air flowing. HVAC
