Product Description

The 3M 7100188877 is a Filtrete Micro Allergen Reduction filter designed to capture both microscopic and large airborne allergens in residential forced-air HVAC systems. Sized at 12 inches x 20 inches x 1 inch, it fits standard 1-inch filter slots found in most residential air handlers and furnaces. The filter targets microscopic particles such as dust, smoke, and smog, as well as larger allergens including mold spores and pet dander. Rated for a 3-month service interval, it is a direct drop-in replacement for any compatible 1-inch filter slot and is handled by HVAC technicians and qualified installers during routine preventive maintenance visits.

This filter is suited for residential forced-air heating and cooling systems where indoor air quality is a service priority. It is commonly installed in applications where occupants have allergy or asthma concerns, or where dust and particulate control is required. The 12 x 20 x 1 inch form factor is one of the most common residential filter sizes, making it widely applicable across a broad range of residential air handlers, furnaces, and heat pumps equipped with a standard 1-inch media slot.

Installation Notes

Air filters of this type are installed by HVAC technicians during routine maintenance or by knowledgeable homeowners. Before replacing the filter, set the thermostat to off and shut down system airflow at the air handler or furnace. Confirm airflow direction arrows on the filter frame match the direction of airflow into the unit before securing the filter housing. Dispose of the used filter in a sealed bag to prevent re-release of captured particulates.
