20x25x4 MERV 13

With the 20x25x4 MERV 13 Air Filter Replacement from Custom Filters Direct, you can improve the air quality in your house. With its superior protection for your furnace, air conditioner, heat pump, or HVAC system, this cutting-edge air filter is designed to make sure that you and your loved ones are breathing in only the purest air.

Advanced Filtration Technology:

The global standard for high-performance air filtration is set by our MERV 13 synthetic medium. This filter is superior since it captures 98% of airborne particles, making it comparable to MPR 1500/1900 and FPR 10 ratings. This filter serves as your first line of protection against a wide range of indoor pollutants, from typical irritants like dust, pollen, and pet dander to more microscopic threats like mold, smog, bacteria, and virus-carrying particles.

Precision Fit and Durability:

Experience a flawless fit with the exact 19.5×24.5×4 air filter dimensions. Your HVAC system will operate at peak efficiency and airflow thanks to this precision. Superior filtration is achieved without sacrificing airflow thanks to the high-quality construction of the filter, which features electrostatically charged pleated filter media. Long-lasting performance is ensured by the sturdy frame’s resistance to heat and humidity, together with the added structural strength provided by the reinforced wire backing.

Extended Lifespan and Low Maintenance:

Say goodbye to replacements that come around too often. When compared to conventional fiberglass models, this air filter’s remarkable 3-month lifespan is a major gain. It is an economical and practical option for your house because of its 300% longer lifespan, which will also result in cleaner air and less maintenance.
