20x25x4 Air Filter Allergen Descriptions

Filter Quality

Standard Allergen 20x25x4 Air Filter: Provides highest airflow rate with adequate air quality filtration for most homes. If you have pets, allergies, or are in a dusty environment, you may want to consider a higher MERV rating.
Allergen Preferred 20x25x4 Air Filter (Most Popular): Great for allergy sufferers and pet owners. Helps prolong the life of your home or office HVAC system. Allergen preferred is a perfect balance of quality and affordability. It is the ideal choice for the majority of homes. 
Allergen Supreme 20x25x4 Air Filter: Provides the cleanest, odor-reduced air. Great for severe allergy and asthma sufferers. Allergen Supreme filters offer a higher MERV rating blocking more allergens and particles. They get dirtier faster and should be changed more often to not restrict airflow to the HVAC system.
