Keep your projector in flawless working order with the Epson High Efficiency Air Filter for PowerLite 6100i. Epson's new filter design dramatically increases the available surface area, so more dust gets trapped. The larger filter area combined with an electrostatic charge traps dust and chalk particles before they enter the projector. This ensures that the air circulating internally is clean for long lasting, reliable performance. The filters are designed to be easily and quickly changed, so you don't have to waste valuable presentation time.
