prismaLINE Coarse Filter (2 pieces )

The Löwenstein Medical prismaLINE Coarse Filter Pack is a dual-piece set of reusable, high-capacity pre-filters engineered for prismaLINE device users who want to protect their equipment from large floating dust particles, pet fur, and fabric lint. Operating a high-performance therapy machine without a functional coarse filter allows large fibers to settle directly onto the internal motor components, increasing noise levels and accelerating mechanical wear. This user-focused replacement pair acts as a heavy-duty front guard, trapping substantial environmental debris before it can enter the machine's air path. Constructed from an open-cell, high-resilience synthetic foam material, these filters are fully washable and designed to maintain their shape and filtration structure through repeated cleaning cycles. The structural dimensions are cut to slide flush into the prismaLINE's dedicated rear intake channel, creating a secure boundary that ensures consistent air entry. Incorporating these durable pre-filters into your weekly cleaning routine prevents premature clogging of your fine filter layers, keeping your nightstand setup running quietly and reliably.
