General Filters 4530 Whole House Air Cleaner Merv 11

Product Description

The GENERAL FILTERS 4530 is a whole-house media air cleaner in the GeneralAire MAC Series, designed for forced-air HVAC systems where indoor air quality is a service priority. It uses Opti-Fiber media engineered for low pressure drop, allowing the air handler to maintain airflow while still capturing airborne particulates. At a rated capacity of 1400 CFM and a MERV 11 filtration rating, the unit traps 75 percent of particles sized 1.0 to 3.0 microns, including fine dust, pollen, mold spores, and similar contaminants. The cabinet measures 20 inches high by 20 inches deep by 7 inches wide. HVAC technicians and installers handle this unit as part of whole-house IAQ system work.

The 4530 is suited for residential forced-air applications where a high-capacity, low-restriction media cleaner is required. It installs inline with the return-air duct system, upstream of the air handler or furnace. The replacement media filter for this unit is model 6FM2020, also referenced as GFI 4556, and the manufacturer recommends filter replacement every six months under normal operating conditions. This service interval makes it a straightforward item to include in a semi-annual maintenance agreement.

Installation Notes

Installation is performed by a licensed HVAC technician. Power to the air handler or furnace must be shut off at the disconnect or breaker before any ductwork modification or unit installation. The unit mounts inline in the return-air duct; verify duct dimensions and airflow direction before securing the cabinet. Follow local mechanical codes and the manufacturer instructions for sealing and fastening the unit to prevent air bypass around the media.
