Frequently Asked Questions

Q: My projector isn't in the 21 models listed above. Can I use the ET-SFD320?

A: The list covers verified models, but it's not exhaustive. Panasonic projectors from the same generation often share air filters. For a safer confirmation, take a photo of the nameplate or the original air filter and send it to Zorsika technical support.

Q: How often should the air filter be replaced?

A: There's no fixed schedule—it mainly depends on the operating environment. In dusty locations, check every 1-2 months; in normal office settings, every 3-6 months. Replace it if you notice gray spots on the image or increased fan noise.

Q: Can the air filter be washed and reused?

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

Q: Why choose Zorsika instead of the original brand?

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

Why Choose Zorsika for the Same Specifications

Zorsika offers a replacement air filter with the same specifications as the original for the ET-SFD320, with key parameters benchmarked against the original, supporting bulk procurement and project supply.

Zorsika's same-spec replacement model fits 21 Panasonic models including PT-SDZ980, PT-SDW930, PT-DW8300, PT-SDW935C, PT-DZ13K, and more. Enter ET-SFD320 in the Zorsika official website query system to see the full compatible model list and corresponding lamp modules.

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

In short: Air filters are consumables—don't skimp on them. Zorsika projector air filters use the same-spec 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 conditions, we also recommend shortening the lamp cleaning cycle.

How Often to Replace? How to Maintain?

• Set the cycle based on the environment: In dusty classrooms or factory settings, check every 1-2 months; in normal office environments, every 3-6 months. Replace earlier if you see gray spots on the image or increased fan noise.
• Don't wash with water: Most projector air filters are single-use consumables. Washing damages the filter media structure and can push dust into the optical path. Only models labeled as washable can be gently vacuumed.
• Keep an eye on it along with 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's condition as well.
• Match the model correctly: Even a slight size difference in the air filter can prevent a proper seal, and dust leakage is as good as not having a filter at all. Before ordering, verify the model using the nameplate or the original filter's label.
