Jinjue Panel Coarse Filters, which are also known as pre-filters, form an essential part of the air filtration system. They are specifically designed to protect the medium and fine filters that follow them in the filtration process. Regular replacement or washing of these pre-filters is recommended every 3-4 weeks to maintain optimal air quality and filtration efficiency.
