NP21LP Air Filter NEC Air Filter Replacement

The NP21LP Air Filter NEC Projector Air Filter is a must-have to keep your projector's optical elements dust-free. This critical component helps prevent dust accumulation, ensuring optimal performance. A clogged air filter can cause higher operating temperatures due to reduced airflow, which could shorten your projector's lamp life. When you're changing your NEC Projector Lamp, it's also wise to replace the filter. Manufacturers recommend replacing the air filter with each lamp change to maintain peak performance. Regularly swapping out your air filter is a simple way to extend the life of both your lamp and projector.
