Koch Filter HBG23036 Pleated Air Filter Merv 11 30x36x2

Product Description

The KOCH FILTER HBG23036 is a large-format pleated air filter rated MERV 11, engineered for geothermal HVAC systems that require high-efficiency filtration in oversized filter housings. At 30 inches by 36 inches by 2 inches, this filter occupies a large footprint and delivers the depth needed to support effective particle capture without excessive pressure drop. The MERV 11 rating means it captures a broad range of airborne particulates including dust, pollen, mold spores, and fine dust particles, making it suitable for systems where indoor air quality is a priority. Licensed HVAC technicians and geothermal system installers are the primary end users of this filter.

This filter is designed for geothermal HVAC applications where standard residential filter sizes are not adequate. Geothermal heat pump systems often use larger air handlers with oversized filter tracks, and the HBG23036 is sized to fit those configurations. The 2-inch depth provides added media surface area compared to 1-inch filters, which supports longer service intervals and more consistent airflow maintenance between change-outs. Typical installation locations include mechanical rooms, utility spaces, and dedicated geothermal air handler enclosures in both residential and light commercial settings.

Key Features

• MERV 11 rated filtration captures dust, pollen, mold spores, and fine particulates
• Large-format 30 x 36 x 2 inch dimensions suit oversized geothermal air handler filter tracks
• 2-inch media depth increases surface area for extended filter life and reduced pressure drop
• Pleated media design maximizes filtration efficiency relative to airflow resistance
• Suitable for residential and light commercial geothermal HVAC installations

Compatibility

Designed as an OEM-style replacement pleated filter for geothermal HVAC air handlers requiring a 30-inch by 36-inch by 2-inch filter with a MERV 11 rating.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler at the disconnect or breaker before accessing the filter compartment. Confirm airflow direction arrows on the filter frame align with the system airflow direction before seating the filter. Follow local mechanical codes and the equipment manufacturer guidelines for recommended filter replacement intervals.
