Key Features

Genuine Löwenstein replacement filters: Designed specifically for the PrismaLINE range to guarantee correct fit and consistent filtration performance. Genuine parts maintain your warranty and keep your device operating as intended.
Coarse dust filtration: Captures airborne dust and larger particles before they can reach the machine's internal components, helping to protect the motor and extend the working life of your device.
Pack of two: Keep a spare on hand so filter changes are never delayed — swap one in and have a replacement ready to go for next time.
Easy to replace: No tools needed. Filters slot in and out quickly, making routine maintenance straightforward even for new CPAP users.

Who Is This For?

These filters are compatible with all Löwenstein PrismaLINE CPAP devices, including the Prisma SMART, Prisma SMART Max, Prisma SOFT Max, Prisma 20A, and Prisma 20C. According to the CPAP Club CPAP filter replacement schedule, filters should be checked monthly and replaced every three months or whenever they appear dirty. If you suffer from allergies, hayfever, or live in a dusty environment, the PrismaLINE hypoallergenic pollen filters offer finer particle filtration and are worth considering alongside your standard filter supply.
