If you wanted your lamps to last their expected lifetime, you had to clean or replace filters. According to Futuresource over 3 million projectors that were sold in the last 10 years have filters that will need cleaning and replacing. For teachers and students, trying to ignore the “clean filter now” warning during class is an unwanted distraction. For IT staff, not cleaning the filter typically means busting your budget on new replacement lamps that can cost up to $400.
With laser projectors, dust can be even a bigger problem, as the high temperature of the laser light can incinerate dust particles and fling them all around the projector in the form of molten goo. The solution – completely seal the projector and certify it for dust contamination using the industry standard IP5X dust test for ruggedized outdoor products such as the Apple Watch or FitBit. Every BenQ laser projector sold since 2018 has a revolutionary sealed design and has been IP5X certified, meaning you or anyone in your school will never have to deal with a nasty, dirty, messy filter ever again.
