ET-RFV300 Projector Filter
Product Overview
ET-RFV300 is the original filter for the series projectors, made of HEPA high-efficiency filter media to block dust from entering the optical engine. The Zorsika equivalent model Z-FLT-RFV300 is custom-made to original specifications, with dimensions and mounting structure identical to the original, allowing direct replacement, with a 180-day warranty.
Why Projector Filters Need Regular Replacement
The projector filter is the first line of defense in the optical dust-proof system. If the filter is clogged or damaged, dust entering the optical engine can adhere to the LCD/DLP chip, causing black spots on the image, reduced brightness, or even optical engine failure. It is recommended to check every 2,000-3,000 hours and replace every 6-12 months depending on the usage environment.

3 Key Points to Avoid When Purchasing Filters
- Distinguish between disposable vs. washable filters — Some low-end models use washable filters; buying the wrong type will result in incompatibility;
- Check filter structure — Some models have an integrated frame design; when purchasing a replacement, confirm whether the frame is included;
- Verify dimensions — Filter sizes vary significantly across different series within the same brand.
