- Mold Precision: Dimensions and clips are molded to original specifications, ensuring a tight fit with no dust leakage
- Stable Supply: Supports bulk procurement and project-based supply
In short: air filters are consumables—don't skimp on them. Zorsika projector air filters use the same filter material specifications as the original, offering greater peace of mind overall.
Note: Filtration performance is significantly affected by the operating environment. In dusty locations, it is recommended to also shorten the lamp cleaning interval.
FAQ
Q: Why choose Zorsika instead of the original brand?
A: Zorsika air filters are manufactured to the original filter material specifications, with consistent 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, filtration precision and fit are guaranteed.
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, check every 1-2 months; in normal office environments, every 3-6 months. Replace it when 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 material and cause dust leakage, so it is not recommended. Only models labeled as washable can be gently vacuumed and reused.
Q: My projector is not in the 6 models listed above. Can I use 24J38371, 24J38381?
A: The list covers verified models but is not exhaustive. NEC projectors of the same generation often share air filters. For a more reliable confirmation, take a photo of the nameplate on the unit or the original filter and send it to Zorsika technical support.
Q: Are installation instructions available for 24J38371, 24J38381?
A: Yes. The air intake locations and filter removal/installation methods are basically the same across these NEC models. Contact Zorsika sales to obtain illustrated or video instructions for the corresponding model.
Air Filter Maintenance Tips
- Set intervals based on environment: In dusty classrooms or factory environments, check every 1-2 months; in normal office environments, every 3-6 months. Replace earlier if you notice gray spots on the image or increased fan noise.
- Do not wash with water: Most projector air filters are single-use consumables. Washing can damage the filter material 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 practice to check the air filter condition as well.
- Match the model correctly: Even a slight size difference in the air filter can prevent a tight fit, and dust leakage is as bad as not having a filter at all. Verify the model using the unit's nameplate or the original filter label before ordering.
