Panasonic PT-SGZ400C Projector Filter
Product Overview
The Panasonic PT-SGZ400C is an original filter for the Panasonic series projectors, using HEPA high-efficiency filter media to block dust from entering the optical engine. Custom-made to original specifications, the size and installation structure are identical to the original, allowing direct replacement. 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, causing black spots on the image, reduced brightness, and 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 Common Mistakes to Avoid When Purchasing Filters
- Distinguish between disposable vs. washable filters — Some low-end models use washable filters; buying the wrong type will prevent installation;
- Pay attention to filter structure — Some models have a one-piece frame design; when purchasing a replacement, confirm whether the frame is included;
- Check dimensions — Filter sizes vary significantly across different series of the same brand.
