What Zorsika Air Filters Offer You

Zorsika provides replacement air filters for the 3-875-777-02 with the same specifications as the original, with key parameters matched item by item against the original. Bulk purchasing and project supply are supported.

• Specification matching: Filter media pore size, thickness, and airflow resistance are matched to original parameters
• Factory testing: Differential pressure and filtration efficiency tests are performed on every batch
• Mold precision: Dimensions and clips are molded to the original specifications, ensuring a tight fit with no dust leakage
• Stable supply: Bulk purchasing and project supply are supported

In short: Air filters are consumables — don't cut corners on them. Zorsika projector air filters use filter media with the same specifications as the original, giving you greater peace of mind overall.

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

How Often Should You Replace It? How to Maintain It?

• Set the interval based on your environment: In dusty classrooms or factory environments, check every 1-2 months; in normal office environments, check every 3-6 months. Replace it sooner if you notice gray spots on the image or increased fan noise.
• Don't wash it with water: Most projector air filters are single-use consumables. Washing them with water damages the filter media structure and can push dust deeper into the optical path. Only models marked 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.
• Make sure the model matches: If the air filter is even slightly off in size, it won't fit properly, and dust leakage is as bad as not having one installed. Before ordering, verify the model against the nameplate on the projector or the label on the original filter.

FAQ

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 environments, every 3-6 months. Replace it when you see gray spots or notice increased noise.

Q: Can the air filter be washed and reused?

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

Q: My projector isn't in the list of 4 models above. Can I use the 3-875-777-02?

A: The list covers verified models, but it doesn't represent all possibilities. Sony products from the same generation often share air filters. For a more reliable answer, take a photo of the nameplate on your projector or the original filter and send it to Zorsika technical support for confirmation.

Q: Why choose Zorsika instead of the original?

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 leaving the factory. Compared to the original, we offer stable supply and better overall value; compared to other alternatives, filtration precision and fit are guaranteed.

Q: Are installation instructions available for the 3-875-777-02?

A: Yes. The air intake locations and filter removal/installation methods for these Sony models are essentially the same. Contact Zorsika sales to get illustrated or video instructions for your specific model.
