Note: Filtration performance depends heavily on usage environment. In dusty conditions, consider shortening lamp cleaning cycles as well.

Common Questions

Q: Why choose Zorsika over OEM?

A: Zorsika air filters are manufactured to OEM filter material specs with matching pore size and air resistance parameters, and undergo pressure differential testing before shipment. Compared to OEM, we offer stable supply at better value; compared to other alternatives, we guarantee filtration accuracy and fit.

Q: How often should I replace the air filter?

A: There's no fixed schedule—it depends on your environment. Dusty locations should check monthly or bi-monthly; typical office use can go 3-6 months. Replace when you see dust buildup or hear increased fan noise.

Q: Can I wash and reuse the air filter?

A: Most projector air filters are single-use consumables. Washing damages the filter media and can cause dust leaks—don't do it. Only filters explicitly marked as washable on the packaging can be reused after light vacuuming.

Q: My model isn't on the list of 35. Can I use NJ22222?

A: The list shows verified models, not all possible ones. Hitachi projectors from the same generation often share filters. Take a photo of your unit's nameplate or original filter and send it to Zorsika technical support for confirmation.

Q: Is there an installation guide for NJ22222?

A: Yes. The air intake position and filter removal/installation process are essentially the same across these Hitachi models. Contact Zorsika sales for illustrated or video guides specific to your model.

Air Filter Daily Maintenance Tips

  • Set Cleaning Schedule Based on Environment: In dusty classrooms or factory environments, check every 1-2 months; for typical office settings, every 3-6 months is sufficient. If you notice gray spots on the image or increased fan noise, replace the filter earlier.
  • Don't Wash with Water: Most projector air filters are single-use consumables. Water washing damages the filter material structure and can push dust into the optical path. Only filters marked as washable can be gently vacuumed.
  • Check with Lamp Replacements: Clogged filters elevate lamp operating temperatures and reduce lamp lifespan. It's safer to inspect the filter condition when replacing the lamp.
  • Match the Correct Model: Even a slight size mismatch means the filter won't seal properly, and dust will bypass the filter entirely. Verify the model number against the unit's nameplate or the original filter label before ordering.
