Lochinvar & A.O. Smith 100289433 Air Filter
The Lochinvar & A.O. Smith 100289433 Air Filter is a critical 14x14x1 disposable air filter designed for high-performance combustion air filtration in commercial and residential heating systems. Engineering-grade media ensures optimal airflow while capturing airborne particulates that can foul burners or compromise blower motor efficiency. As a genuine OEM replacement part, this 14x14x1 HVAC filter maintains the factory-specified pressure drop across the heat exchanger, preventing premature component fatigue. It is specifically engineered for compatibility with Lochinvar Knight and A.O. Smith boiler series, including models such as the FBL, FBN, and OFN units. Replacing a 100188913 or FIL20001 with this 100289433 filter ensures that your equipment operates within its designed combustion air filtration parameters. Field technicians prioritize this disposable furnace filter for its rigid frame construction, which prevents bypass and collapsing under high-static pressure loads common in condensing boiler applications.
- OEM Compatibility: Exact fit for Lochinvar Knight and A.O. Smith boilers, replacing legacy part numbers 100188913 and FIL20001.
- Optimized Pressure Drop: Designed to maintain strict airflow requirements to prevent "low air" fault codes and ensure stable combustion.
- System Longevity: Captures dust and debris before they reach sensitive internal components like the blower wheel and burner plate.
- Standardized Dimensions: Nominal 14" x 14" x 1" sizing with a heavy-duty frame to resist moisture and high temperatures during peak cycles.
Common Questions
How often should I replace the 100289433 filter in a commercial boiler?
Technicians should inspect the filter during every PM (preventative maintenance) visit. In high-cycle commercial environments or areas with heavy construction dust, monthly replacement is recommended to avoid airflow restriction.
What happens if I use a generic 14x14x1 filter instead of the 100289433?
Generic filters often have different pleat densities. Using a non-OEM filter can lead to improper air-to-fuel ratios, resulting in inefficient combustion, increased carbon buildup on the burner, or system lockout.
Can this filter be vacuumed or cleaned?
No, this is a disposable media filter. Attempting to clean the mesh or pleats can damage the fibers and allow contaminants to enter the combustion chamber, potentially damaging the heat exchanger.
