Genuine Makita replacement filter 443138-2 — a direct-fit service part designed to restore proper ventilation and dust protection in Makita rotary-hammer/hammer-drill housings.

This compact filter sits inside the inner housing next to the air duct to keep dust out of the motor and cooling passages; replacing a clogged or torn filter helps maintain cooling and prolongs tool life.

Fits a number of Makita hammer-drill and rotary-hammer models, including : DHR182, DHR171, HR166D , HR140D , HR3200C / HR3210C / HR3210CT / HR3210FCT, and HR3540C / HR3541FC — sold as the single filter part shown in Makita parts lists.

Easy to install as a straight swap into the tool’s inner housing (no modification required); replace whenever the element is visibly clogged, torn, or when airflow / cooling seems reduced.

Part number: 443138-2 — genuine Makita filter, supplied as one filter per part listing.
