The PT-FW100NTU features the Micro Cut Filter, a high-efficiency electrostatic filter. The used section of the filter is periodically wound into the casing, so top filtering performance is continually maintained. Depending upon the usage environment, this innovation allows the filter to last from 3,000-5,000 hours. The auto-rolling filter combines with a totally reengineered airflow path and a hermetic, dust-free optical system design to assure that the air inside the projector is clean at all times. This minimizes any brightness loss due to dust accumulation, thus lowering your maintenance costs and your total cost of ownership.
