You might be wondering

Q: My machine isn't on the list of 21 models above. Can I use the ET-SFD320?

A: The list covers verified models, but it doesn't represent all of them. Panasonic products of the same generation often share the same air filter. It's safer to take a photo of the unit's nameplate or the original air filter and send it to Zorsika technical support for confirmation.

Q: How often should the air filter be replaced?

A: There's no fixed number of days—it mainly depends on the usage environment. In dusty locations, check every 1-2 months; in a normal office, every 3-6 months. Replace it if gray spots appear or the noise increases.

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

A: Most projector air filters are disposable consumables. Washing with water damages the filter material and causes dust leakage, so it's not recommended. Only models marked as washable on the packaging can be reused after lightly vacuuming.

Q: Why choose Zorsika instead of the original?

A: Zorsika air filters are produced to the original filter material specifications, with matching pore size and airflow resistance parameters, and each batch undergoes pressure differential testing before leaving the factory. Compared with the original, supply is stable and overall value is better; compared with other alternatives, filtration accuracy and fit are guaranteed.

Same specifications—why we recommend Zorsika

Zorsika offers an original-spec replacement air filter for the ET-SFD320, with key parameters benchmarked item by item against the original, and supports bulk purchasing 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 find the complete model compatibility list and the corresponding lamp module.

• Specification benchmarking: Filter material pore size, thickness, and airflow resistance matched to original parameters
• Factory testing: Pressure differential and filtration efficiency tests performed batch by batch
• Tooling precision: Dimensions and clips tooled to the original, fitting tightly with no dust leakage
• Stable supply: Supports bulk purchasing and project supply

In one sentence: An air filter is a consumable—don't cut corners on it. Zorsika projector air filters use original-spec filter material for greater peace of mind.

Note: Filtration performance is greatly affected by the usage environment. In heavily dusty locations, it's advisable to also shorten the lamp cleaning interval.

How often to replace? How to maintain?

• Set the interval based on environment: In dusty classrooms or factory environments, check every 1-2 months; in a normal office environment, 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 with water damages the filter material structure and can actually push dust into the optical path. Only models marked as washable can be lightly vacuumed.
• Pay attention alongside the lamp: A clogged air filter raises the lamp's operating temperature and shortens lamp life. It's safer to check the air filter's condition when replacing the lamp.
• Match the model precisely: If the air filter dimensions are even slightly off, it won't fit tightly, and dust leakage is as good as not installing it at all. Before ordering, verify the model using the unit's nameplate or the original air filter label.
