ET-RFV300 Projector Filter
Product Overview
ET-RFV300 is the original filter for the series projector, made of HEPA high-efficiency filter material to block dust from entering the optical engine. Customized according to OEM specifications, with identical dimensions and mounting structure to the original, it can be directly replaced and comes with a 180-day warranty.
Why Projector Filters Need Regular Replacement
The projector filter is the first barrier in the optical path dust protection system. If the filter is clogged or damaged, dust entering the optical engine will adhere to the LCD/DLP chip, resulting in black spots on the screen, reduced brightness, and even optical engine failure. It is recommended to inspect every 2,000-3,000 hours and replace every 6-12 months depending on the usage environment.

3 Pitfalls to Avoid When Purchasing Filters
- Distinguish Disposable vs. Washable Filters — Some low-end models use washable filters; ordering the wrong type may result in incompatibility;
- Pay Attention to Filter Structure — Some models have a one-piece frame design; when buying replacement filters, confirm whether the frame is included;
- Check Dimensions — Filter sizes vary significantly across different series of the same brand.
