The Smog-Hog Unicell 02-1921-S is a two-stage electrostatic collection cell for the SG, SGN, PSG, and MSH-11 series industrial air cleaners. Unlike a separate ionizer and cell, the unicell integrates both stages into a single Penney-type unit: incoming particles are charged in the first stage and then captured on the collector plates in the second, all within one component.

Built to capture oil mist, welding smoke, and industrial dust, the unicell is washable and reusable, so routine cleaning restores its capture capacity instead of requiring disposable media. That keeps long-term operating costs low while maintaining the capture efficiency your SG or SGN system was designed to deliver.

This genuine OEM unicell fits Smog-Hog SG, SGN, PSG, and MSH-11 units. Contact our team if you need help confirming the correct cell for your model and configuration.
