HIGH PERFORMANCE FILTRATION: Our MERV 13 furnace filter uses electrostatically charged fibers to capture over 90% of particles ranging from 0.3 to 1.0 microns, effectively holding 30% more dust compared to standard filters. REDUCED ENERGY CONSUMPTION: Perfect Aire furnace filters in the size are engineered to reduce energy consumption and help protect your HVAC system, thanks to a lower in-use pressure drop compared to traditional filters. DUAL AIRFLOW TECHNOLOGY: Our innovative design allows air to flow through the filter in either direction, simplifying the installation process and reducing the chance of errors, while still delivering effective filtration performance. 90 DAY AIR FLOW MERV 13 FILTER: This electrostatic air filter is designed to provide optimal airflow and filtration within your home or office for up to 90 days. Depending on usage and environmental conditions, replacement may be needed more frequently. DUAL LAYER TECHNOLOGY: Our air filters feature dual-layer media technology, providing superior filtration and a higher pleat count for increased longevity compared to traditional fiberglass filters. Improve your indoor air quality with the Perfect Aire Elite MERV 13 air filters, designed for use in both homes and offices. MERV (Minimum Efficiency Reporting Value) is a rating system that measures the effectiveness of air filters in capturing airborne particles. A MERV 13 filter is highly effective at capturing over 90% of particles between 0.3 and 1.0 microns, making it an excellent option for environments where clean air is a priority. This electrostatic furnace filter utilizes charged fibers to attract and capture microscopic particles, including common airborne pollutants. The Perfect Aire Elite filter is constructed from durable synthetic materials and features Dual Layer Media, which helps improve energy efficiency and reduces strain on your HVAC system by lowering the pressure drop during use. With its dual airflow design, the filter ensures simple and error-free installation, distinguishing it from other air filters in the market. Additionally, its higher pleat count contributes to a longer lifespan, allowing it to last up to 3 months before needing replacement.
