Check before buying

• Count your old grids before ordering: this kit is intended for a seven-plus-one arrangement.
• If your filter uses individual replacement grids, verify whether you need the complete assembly rather than single grids.

Do not substitute by square footage alone; grid kits can differ by span configuration. A matching part number on your old kit is the clearest evidence that this replacement set is intended for your filter.
