The RESEARCH PRODUCTS 1413 is an upgrade kit designed for the 2400 and 2140 series air cleaners. It replaces the older 104 and 401 components with an improved filter assembly that removes nearly twice the contaminants of the original configuration. The kit includes a replacement filter (model 413) and is engineered for units fitted with plastic, non-metal doors. Installation requires no tools and is completed in minutes, making this a practical one-time retrofit for HVAC technicians and knowledgeable service professionals performing preventive maintenance or equipment upgrades.
This kit is used in residential air cleaner installations where a 2400 or 2140 unit is already in service. It is suited for retrofits during routine filter service calls or planned equipment upgrades. The no-tool installation process reduces labor time on site. Because this is a one-time upgrade, the improvement carries forward with every subsequent filter change, simplifying ongoing maintenance for both service techs and end users.
Designed as a direct upgrade replacement for RESEARCH PRODUCTS air cleaner models 2400 and 2140. Replaces components 104 and 401. Fits units with plastic (non-metal) doors only.
Installation is performed by an HVAC technician or qualified service professional. Power down the air handler or furnace system before accessing the air cleaner cabinet. No tools are required for this kit; follow the manufacturer instruction sheet included in the package. Confirm the unit has plastic (non-metal) doors before installing, as this kit is not designed for metal-door configurations.
