About This

• Washable MERV 11 Air Filter — Right for You If: You replace disposable 20x20x1 filters every 60-90 days and want to stop — or have pets or allergies. Captures dust, pollen, pet dander, and fine airborne particles. Fits most 20x20x1 HVAC units — 2-Pack
• How to Clean in 3 Steps: Remove filter, rinse from the clean side with water, let air dry fully before reinstalling. Clean every 1-3 months or when you see visible dirt. Never reinstall wet — dry fully first to maintain MERV 11 filtration performance
• Lasts Years vs 90 Days for Disposables: Standard 20x20x1 filters cost $5-15 each and clog in 60-90 days — this washable filter replaces 10-20 disposables over its lifetime. Aluminum alloy frame holds shape wash after wash, unlike cardboard disposables
• Electrostatic MERV 11 — Better Than MERV 8: Nylon mesh self-charges during airflow to capture more particles per pass than non-electrostatic filters. Works with most 20x20x1 furnace, AC, and HVAC systems. Superior to standard MERV 8 disposable filters
• AISPA vs K&N and Disposables: Washable aluminum-framed design outlasts dozens of single-use filters. MERV 11 captures dust, pollen, pet dander, and fine airborne particles. 2-Pack ensures a spare is ready when the other is drying after cleaning
