Frequently Asked Questions

Q: My projector is not on the list of 21 models above. Can I use the ET-SFD310?

A: The list represents verified models but is not exhaustive. Panasonic products from the same generation often share the same air filter. For a more reliable confirmation, take a photo of the nameplate on the projector body or the original air filter and send it to Zorsika technical support.

Q: How often should the air filter be replaced?

A: There is no fixed schedule; it mainly depends on the operating environment. In dusty locations, we recommend checking every 1-2 months; for normal office environments, every 3-6 months. Replace the filter as soon as gray spots appear or noise increases.

Q: Can the air filter be washed with water and reused?

A: Most projector air filters are single-use consumables. Washing them with water can damage the filter media and cause dust leakage, so it is not recommended. Only models explicitly labeled as washable can be gently vacuumed and reused.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika air filters are manufactured to the original filter media specifications, with consistent pore size and airflow resistance parameters, and each batch undergoes differential pressure testing before shipment. Compared to the original manufacturer, we offer more stable supply and better overall value; compared to other alternatives, our filtration precision and fit are more reliable.

Why Choose Zorsika

The ET-SFD310 is a high-consumption model. Zorsika manufactures it to the original filter media specifications, with the filter media and sealing edge strips controlled to original parameters, ensuring better filtration precision and fit.

Zorsika's equivalent replacement model fits 21 Panasonic projector models, including the PT-SDZ980, PT-SDW930, PT-DW8300, PT-SDW935C, and PT-DZ13K. Enter ET-SFD310 in the Zorsika official website query system to view the full list of compatible models and corresponding lamp modules.

• Specification Alignment: Filter media pore size, thickness, and airflow resistance matched to original parameters
• Factory Testing: Differential pressure and filtration efficiency tests performed on every batch
• Warranty Commitment: Warranty provided under normal use
• Stable Supply: Supports bulk purchasing and project-based supply

In short: the air filter is a consumable item — don't skimp on it. Zorsika projector air filters use the same specification filter media as the original, giving you greater peace of mind overall.

Note: Filtration performance is highly dependent on the operating environment. In heavily dusty locations, we recommend shortening the lamp cleaning interval as well.

How Often to Replace? How to Maintain?

• Set the cycle based on the environment: In dusty classrooms or factory environments, check every 1-2 months; in normal office environments, every 3-6 months. Replace the filter earlier if gray spots appear on the image or fan noise increases.
• Don't wash with water: Most projector air filters are single-use consumables. Washing can damage the filter media structure and push dust into the optical path. Only models labeled as washable can be gently vacuumed.
• Monitor alongside the lamp: A clogged air filter raises the lamp's operating temperature and shortens its lifespan. When replacing the lamp, it's a good idea to check the air filter condition as well.
• Match the model correctly: Even a slight size difference in the air filter can prevent a proper seal, allowing dust to leak in — the same as not having a filter at all. Before ordering, verify the model using the nameplate on the projector body or the label on the original filter.
