NEC NP-M271X User Manual page 130

To replace the filters:
Four filters are made of non-woven white material, packaged with the replacement lamp.
Honeycomb hard filter: Large and small sizes (attached to the filter unit)
Accordion soft filter: Large and small sizes (attached to the filter cover)
NOTE:
• Replace all four filters at the same time.
• Before replacing the filters, wipe off dust and dirt from the projector cabinet.
• The projector is precision equipment. Keep out dust and dirt during filter replacement.
• Do not wash the filters with soap and water. Soap and water will damage the filter membrane.
• Put filters into place. Incorrect attachment of a filter may cause dust and dirt to get into the inside of the projector.
TIP:
While the material of filters attached to the projector at the time of purchase is different from the material of filters included with the
optional lamp, there is no difference in performance between these two types.
Before replacing the filters, replace the lamp. (→ page 117)
