The Toyotomi Circulation Air Filter for OM-22, OM-23, L530, L531, and L532, part number 20479840, is a replacement air filtration element designed to fit the circulation fan assemblies in select Toyotomi Toyostove heater models. It traps dust, lint, and airborne debris drawn through the heater’s air circulation system to help maintain clean airflow, protect internal components, and support consistent heating performance. This filter is manufactured to the original equipment specifications so it installs directly into the fan housing during routine maintenance or service replacement.
This circulation air filter is intended to be replaced when it becomes visibly dirty, clogged, or restricts airflow, which can reduce heating efficiency and place additional strain on the blower motor. A clean filter helps maintain stable airflow and ensures the heater’s circulation system moves warm air effectively throughout the space. Installation should follow the model’s maintenance instructions, ensuring the filter is oriented correctly and seated securely within the fan housing before returning the heater to operation.
What’s Included: One (1) Toyotomi circulation air filter for compatible heater models.
Installation Limits: For replacement use only on specified Toyotomi heater circulation fan assemblies; install with the heater powered off and ensure proper seating in the fan housing to avoid airflow restrictions.
Compatibility: Compatible with Toyotomi Toyostove models OM-22, OM-23, L530, L531, and L532 that require the 20479840 circulation air filter.
