Innovative Solutions ProGuard DXB Mini Replacement PCO Kit (6458)

What is included in this DXB Mini replacement PCO cell kit?

This kit includes the replacement PCO cell for the ProGuard DXB Mini — the titanium catalyst honeycomb with UV bulb that generates the unit's active sanitization.

How do I know I'm ordering the right cell for my unit?

Flip the unit over. There's a four-digit model number on a sticker on the back of the housing — not on the cell itself. That number determines which cell kit matches your specific unit. If you're ordering through ProGuard directly, providing that number lets them match it against their internal spreadsheet; when ordering through Hydrobuilder, check the listing title against your unit's serial plate to confirm the right match.

How often should this cell be replaced?

Annually. The cell is what generates the sanitization — it's a required yearly maintenance item, not optional, to keep the unit performing at full effectiveness.

What happens if I install the wrong cell for my unit?

Cells are matched to specific unit generations and model numbers. An incorrect cell may not fit or perform correctly — if you're unsure which cell your unit needs, confirm the four-digit model number on the back sticker before ordering.
