Experience cleaner air with the Aprilaire 213CBN replacement filter, designed to work with Aprilaire whole-house air purifiers. This 4-inch filter blends MERV 13 filtration with a carbon layer to help address household odors and common airborne irritants as air circulates through your system.

Built for real life, the 213CBN adds activated carbon to capture odors from pets, cooking, and everyday VOCs, while continuing to trap everyday allergens. Think of the feel of air that smells fresher after cooking, or the moment you notice less lingering pet aromas drifting through the rooms. It’s a practical enhancement for households seeking a healthier atmosphere without sacrificing comfort.

Key benefits at a glance

• Odor reduction: carbon-activated layer targets pet smells, cooking notes, and VOCs as air passes through the filter.
• Allergen filtration: robust MERV 13 performance helps capture pollen, mold spores, bacteria, pet dander, dust, and dust mites.
• Efficient filtration area: four inches of media provide a high surface area (28 square feet) for strong particle capture.
