Why Choose Zorsika

For commonly used filters like the ET-RFL400, Zorsika manufactures to OEM filter media specifications — pore size, thickness, and airflow resistance are all benchmarked against the original, and every batch undergoes pressure differential testing before shipment, so it's ready to use right out of the box.

Zorsika's equivalent model Z-RFV300 fits 23 models including the Panasonic PT-BX441C, PT-VX430, PT-VW360, PT-BW410C, and PT-BW370C. Enter Z-RFV300 in the Zorsika website search system to view the complete model compatibility list and the corresponding lamp module.

• Specification matching: Filter media pore size, thickness, and airflow resistance matched to OEM parameters
• Factory testing: Pressure differential and filtration efficiency tested batch by batch
• Tooling precision: Dimensions and clips tooled to OEM specs for a tight, dust-proof fit
• Stable supply: Bulk purchasing and project supply supported

In short: air filters are consumables, so don't cut corners on them — Zorsika projector air filters use the same specification filter media as the original, for greater peace of mind overall.

Note: Filtration performance is heavily affected by the operating environment. In dusty locations, we recommend also shortening 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 typical 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 with water damages the filter media structure and can actually push dust into the optical path. Only models labeled as washable can be lightly vacuumed.
• Keep an eye on it alongside the lamp: A clogged air filter raises the lamp's operating temperature and shortens its life. Checking the filter when you replace the lamp is the safer approach.
• Match the model exactly: Even a slight size difference means the filter won't fit tightly, and a loose fit lets dust through — as good as not installing one at all. Before ordering, verify the model using the unit's nameplate or the original filter label.

FAQ

Q: How often should the air filter be replaced?

A: There's no fixed number of days — it mainly depends on the operating environment. In dusty locations, check every 1-2 months; in typical offices, every 3-6 months. Replace it if gray spots appear or 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 media and causes dust leakage, so it's not recommended. Only models labeled as washable on the packaging can be lightly vacuumed and reused.

Q: My projector isn't on the 23-model list above — can it use the ET-RFL400?

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

Q: Why choose Zorsika instead of the OEM?

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

Q: Does the ET-RFL400 come with installation instructions?

A: Yes. The air intake location and filter removal/installation method are basically the same across these Panasonic models. Contact Zorsika sales for illustrated or video instructions for your specific model.
