The Smog-Hog 33-0115 is a reusable aluminum mesh prefilter engineered for the SG and SGN electrostatic precipitator series. It mechanically traps large mist and smoke particles before the air stream reaches the ESP core, preconditioning the incoming air and reducing the operational load on the main collection cells.

Built from washable aluminum mesh, this prefilter is designed to be cleaned and reinstalled rather than thrown away. By capturing large debris up front, it minimizes heavy buildup on the internal components, which helps maintain proper static pressure and airflow and keeps your air cleaner running smoothly between service cycles.

As a genuine Smog-Hog replacement part, the 33-0115 is a simple, cost-effective way to protect the cells and preserve capture performance on your SG or SGN unit. Contact our team if you need help confirming the right prefilter for your model.
