Mann Hummel Disposable Fiberglass Filters

Overview

The MANN HUMMEL 16x25x1f is a fiberglass panel air filter rated MERV 4, designed for use in residential and light commercial forced-air HVAC systems. At 16 inches wide by 25 inches tall by 1 inch deep, it fits standard filter slots in air handlers, furnaces, and return-air grilles. A MERV 4 rating captures larger airborne particles such as dust, pollen, and carpet fibers, making it a suitable choice for basic system protection where high filtration efficiency is not required. Licensed HVAC technicians and knowledgeable DIYers typically install this filter as part of routine preventive maintenance. This filter is sized for high-volume residential and light commercial applications where a 16x25x1 inch filter slot is specified. It is well-suited for standard gas furnaces, air handlers, and central air conditioning systems requiring a low-restriction panel filter. The fiberglass media keeps static pressure drop minimal, which can be important in older systems or those with weaker blower motors. It is commonly used in multi-unit residential buildings, rental properties, and any application where frequent filter changes at low cost are the priority.
