Honeywell Home FC40R1830/U 18" x 30" MERV 10 Return Grille Media Air Filter
The Honeywell Home FC40R1830/U is a high-efficiency MERV 10 return grille media air filter designed to provide greater filtration capacity and longer service life than conventional 1-inch HVAC filters.
Measuring 18 x 30 x 3 inches, the FC40R1830/U installs in most compatible return filter grilles and uses deep pleated filter media to provide increased surface area for capturing airborne particles.
With a maximum airflow capacity of 1,550 CFM, the filter combines effective particle capture with a low pressure drop to help maintain comfortable airflow and HVAC equipment efficiency.
The FC40 Series is rated MERV 10, making the FC40R1830/U a practical filtration upgrade for residential and light commercial heating and cooling systems.

Honeywell Home FC40 Series
MERV 10 Filtration
The FC40R1830/U carries a MERV 10 rating, providing enhanced filtration compared with many basic residential HVAC filters.
Its pleated media captures airborne particles as return air circulates through the filter before entering the HVAC equipment. The deeper media design provides greater surface area and particle-holding capacity without unnecessarily restricting airflow.
3-Inch Deep Pleated Design
The FC40R1830/U features 3-inch-deep pleated filter media, providing significantly more filtration surface area than a conventional 1-inch filter.
The additional media capacity can provide longer service intervals while helping the HVAC system maintain consistent airflow as particles accumulate.
Actual replacement intervals will depend on system usage, indoor air conditions, pets, construction activity, and other environmental factors.
Low Pressure Drop
Effective filtration should not unnecessarily restrict the HVAC system's airflow.
The FC40R1830/U has a static pressure drop of 0.12 in. w.c. at 300 FPM, helping provide comfortable airflow while maintaining effective particle filtration.
Its maximum rated airflow capacity is 1,550 CFM (2,610 m³/hr).
Fractional Efficiency
The FC40R1830/U provides the following fractional efficiency performance:
-
E1: 31% for particles from 0.3 to 1.0 microns
-
E2: 61% for particles from 1.0 to 3.0 microns
-
E3: 86% for larger particles
Efficiency performance is based on the applicable ASHRAE 52.2 testing standard.
