NJ22211 Hitachi Air Filter Replacement

The NJ22211 Hitachi 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 Hitachi 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.

Wow, what a difference a new lamp makes! The Hitachi NJ22211 is practically shining again, like the first day we installed it, thanks to Projectorlamps.com. No more dim, washed-out images during movie day; the colors are vibrant and the picture is sharp enough that even the kids in the back row can see clearly now.
