What Zorsika Air Filters Offer You

For commonly used air filters like 79TCP521,79TCP531, Zorsika manufactures to OEM filter material specifications, matching pore size, thickness, and airflow resistance item by item against the OEM, with batch-by-batch pressure differential testing before shipment, so they work properly as soon as installed.

Zorsika's same-spec replacement model fits 3 projector models including NEC NP-U321H, NP-U321HJD, NP-U321H-WK; enter 79TCP521,79TCP531 in the query system on the Zorsika official website to find the complete model compatibility list and corresponding lamp module.

• Spec matching: Filter material pore size, thickness, and airflow resistance matched to OEM parameters
• Factory testing: Batch-by-batch pressure differential and filtration efficiency testing
• Tooling precision: Dimensions and clips tooled to OEM specs for a tight fit with no dust leakage
• Stable supply: Supports bulk purchasing and project supply

In one sentence: Air filters are consumables — don't skimp on them. Zorsika projector air filters use OEM-equivalent filter material for greater peace of mind overall.

Note: Filtration effectiveness is heavily influenced by the usage environment. In dusty locations, it's advisable to also shorten the lamp cleaning cycle.

FAQ

Q: Why choose Zorsika instead of OEM?

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

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 ordinary office settings, every 3-6 months. Replace when gray spots appear or noise increases.

Q: Can the air filter be washed and reused?

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

Q: My machine isn't among the 3 models listed above — can I use 79TCP521,79TCP531?

A: The list covers verified models, not all of them. NEC products of the same generation often share air filters. 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: Is there an installation guide for 79TCP521,79TCP531?

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

Air Filter Routine Maintenance Tips

• Set the cycle based on environment: In dusty classrooms or factory environments, check every 1-2 months; in ordinary 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 damages the filter material structure and actually pushes 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 wise to check the air filter condition when replacing the lamp.
• Match the model precisely: Even a slight size difference means the air filter won't fit tightly, and dust leakage is as bad as not installing one at all. Before ordering, verify the model using the unit's nameplate or the original air filter label.
