Honeywell MERV 11 Allergen Reducer 20x25x1 – Electrostatic Pleated HVAC Filter (4-Pack) Made in USA

Experience cleaner indoor air with Honeywell MERV 11 Allergen Reducer 11000

Upgrade your home air with the Honeywell MERV 11 Allergen Reducer 11000 electrostatic pleated HVAC filter. Built for residential use, it blends a dense pleated media with an electrostatic charge to capture a broader range of airborne particles as air passes through. The result is a crisper, fresher feel in living spaces where you spend time with family and pets.

The 20x25x1 filter fits most brands and works with air conditioners, furnaces, heat pumps and HVAC units. With a MERV 11 rating, it can trap up to 85 percent of large airborne particles, including pollen, pet dander, dust mite debris and many smoke particles, helping to keep rooms feeling more comfortable during allergy seasons or city smoke events.

This filter is designed to provide steady filtration performance over time. The electrostatic charged media helps attract and hold smaller particles, potentially reducing the amount of irritants circulating in your home. Compared with standard 1 inch filters, this pleated design offers more surface area for filtration and longer life between changes, giving you less frequent replacements and more confidence in daily use.

To maintain optimal filtration performance, replace the filter at least every 90 days. Regular replacement may help maintain airflow and reduce the workload on your heating and cooling system, which can contribute to smoother operation and potentially lower energy use when the system runs efficiently. Keeping the system in balance can translate to quieter operation and more consistent temperatures in living spaces.

Country of origin matters to many shoppers. Each Honeywell filter is proudly made in the United States, reflecting a commitment to domestic manufacturing and quality control. Replacing the filter is straightforward: measure your current filter, compare sizes, and install the new unit according to the packaging instructions. A ready-to-use four pack helps you plan maintenance across rooms and seasons without hunting for replacements.
