This is an Epson Replacement Air Filter. It is compatible with HC6100 / 6500UB / 8100 and HC8500UB projectors.
A clean air filter positively affects the life span of the lamp as well as protecting the internal working parts of the projector against debris, dust and other contaminants.
It fits perfectly in the slot. The temperature light went off after I put it in. My projector is running great with the new filter.
Easy to use this product. If you want to use your Epson projector you must clean every 30 days and change the filter in every year at least. I advise this product who have compatible Epson projectors.
