Bulk Air Filter (Ballard)

From a construction job, for removing bulk dust. Eleven full sheets and 2 partial, 25" x 25" x 2". The blue layer is 1/2" thick and somewhat sticky making it rather effective at removing fine dust once the white layer removes course material. Been using them it to pre-filter the return air for my home heating system, but it could be mounted to a box fan to control dust in any dust generating area.

In Ballard near the Goodwill store. Preference given to requests with specific date and time for pickup.
