Compatible Projector Models

This air filter fits the 3M Digital X21, X21i, X26 and X26i projectors. It replaces part number 78-8138-1096-3 during routine maintenance or lamp changes. The component weighs 0.2500 units and measures 51mm by 105mm by 5mm.

Maintenance Intervals and Limits

Manufacturers suggest cleaning the filter every three months and replacing it when the lamp is changed. A clogged filter reduces cooling fan effectiveness and causes internal heat buildup that shortens projector life. Some models display a warning icon when replacement is needed.

Upgrade From Clogged or Missing Filters

This part replaces a dirty, damaged or missing filter that can no longer trap dust before it reaches optical elements. The jump is worth it when a filter warning appears, when visual inspection shows any buildup, or at every lamp replacement to protect the new bulb. It is not for projectors outside the listed model range or for users who need a washable permanent filter.
