- Specification matching: Filter media pore size, thickness, and airflow resistance matched to OEM parameters
- Factory testing: Batch-by-batch pressure differential and filtration efficiency testing
- Mold precision: Dimensions and clips tooled to OEM specifications for a tight seal with no dust leakage
- Stable supply: Supports bulk purchasing and project supply
In short: air filters are consumables — don't cut corners on them. Zorsika projector air filters use OEM-equivalent filter media for a more worry-free experience overall.
Note: Filtration effectiveness is greatly affected by the usage environment. In dusty locations, it is recommended to also shorten the lamp cleaning cycle.
Frequently Asked Questions
Q: Why choose Zorsika instead of OEM?
A: Zorsika air filters are produced to OEM filter material specifications, with matching pore size and airflow resistance parameters, and batch-by-batch pressure differential testing before shipment. Compared to OEM, supply is more stable and overall value is better; compared to other alternatives, filtration accuracy and fit are guaranteed.
Q: How often should the air filter be replaced?
A: There is no fixed schedule — it mainly depends on the usage environment. In dusty locations, check every 1-2 months; in normal office environments, every 3-6 months. Replace when gray spots appear or noise increases.
Q: Can the air filter be washed and reused?
A: Most projector air filters are disposable consumables. Washing damages the filter media and causes dust leakage, so it is not recommended. Only models marked as washable on the packaging can be lightly vacuumed and reused.
Q: My projector is not on the list of 21 models above — can I use ET-SFR320?
A: The list covers verified models, not all of them. Panasonic products of the same generation often share air filters. It is safer to send a photo of the nameplate or the original air filter to Zorsika technical support for confirmation.
Q: Does ET-SFR320 come with installation instructions?
A: Yes. The air intake locations and air filter removal/installation methods are basically the same across these Panasonic models. Contact Zorsika sales for illustrated or video instructions for your specific model.
Air Filter Routine Maintenance Tips
- Set the cycle based on environment: In dusty classrooms or factory environments, check every 1-2 months; in normal office environments, every 3-6 months. Replace early if gray spots appear on the image or fan noise increases.
- Don't wash with water: Most projector air filters are disposable consumables. Washing damages the filter media structure and actually pushes dust into the optical path. Only models marked as washable can be lightly vacuumed for reuse.
- Pay attention alongside the lamp: A clogged air filter raises the lamp's operating temperature and shortens lamp life. It is wise to check the air filter status when replacing the lamp.
- Match the model precisely: Even a slight size difference means the air filter won't seal properly — dust leakage is as bad as no filter at all. Before ordering, verify the model using the projector nameplate or the original air filter label.
