ET-RFV400 Projector Filter
Product Overview
ET-RFV400 is the original filter for the series projector, using HEPA high-efficiency filter material to block dust from entering the optical engine. Zorsika equivalent model Z-FLT-RFV400 is custom-made to original specifications, with dimensions and installation structure identical to the original for direct replacement, backed by a 180-day warranty.
Why Projector Filters Need Regular Replacement
The projector filter is the first line of defense in the optical path dust protection system. If the filter becomes clogged or damaged, dust entering the optical engine can adhere to the LCD/DLP chip, causing black spots on the screen, reduced brightness, or even optical engine failure. It is recommended to inspect 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
- Distinguish Between Disposable vs. Washable Filters — Some low-end models use washable filters; buying the wrong type may prevent installation.
- Pay Attention to Filter Structure — Some models have an integrated frame design; when purchasing alternatives, confirm whether the frame is included.
- Verify Dimensions — Filters from different series within the same brand can vary significantly in size.
