ET-RFL400 Projector Filter
Product Overview
ET-RFL400 is the original filter for the series projectors, made of HEPA high-efficiency filter material to block dust from entering the optical engine. The Zorsika equivalent model Z-FLT-RFL400 is customized according to original specifications, with consistent dimensions and mounting structure, 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 path dust prevention system. If the filter becomes clogged or damaged, dust entering the optical engine can adhere to LCD/DLP chips, causing black spots on the image, brightness loss, 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 operating environment.

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