Maintenance Intervals and Heat Protection

Manufacturers suggest cleaning the filter every 3 months and replacing it when changing the lamp. A clogged filter reduces cooling fan effectiveness and causes internal heat buildup that shortens projector and bulb life. Many units display a filter warning icon when replacement is required immediately.

Installation and Durability

The filter is designed for quick, easy installation during regular maintenance or lamp replacement. Its durable construction optimises airflow to protect optical components from dust accumulation. No additional accessories or software are included with this single replacement filter unit.

Questions about this item

Will this UX38851 filter fit my CP-EX300 projector without modification?

Yes, the UX38851 is listed as compatible with the CP-EX300 and CP-EX300N models, so it installs directly into the existing filter slot.

How can I confirm the new filter is seated correctly after installation?

After fitting the filter, power on the projector and check that no filter-warning icon appears on screen; the cooling fan should run at normal speed without overheating alerts.

Does the package include any tools or extra gaskets, or just the filter itself?

The box contains only the UX38851 air filter; no tools, screws or additional gaskets are supplied.
