CPAP Filters Inline, 20 Refills, 5 Housings, 22mm & 25mm CPAP/BiPAP Tube

About this item

• 20 FILTER CHANGES, NOT 12: Get 20 filter changes in one kit. While many standard inline filter packs include just 12 single-use units, our kit includes 20 replaceable filter discs and 5 reusable twist-lock housings. Each housing is designed for use with 4 filter discs. Replace the disc regularly, or sooner if it becomes visibly dirty or wet.
• FITS 22MM HOSE AND 25MM MACHINE OUTLET, TWO WAYS Dual connector: 22mm on the hose side, 25mm on the machine / mask side. Method 1: Connect the filter between your machine outlet and hose. Method 2: Connect the filter between your hose and mask elbow and is recommended when using a heated or climate-controlled tube. Both setups are illustrated in the product images and on the instruction card included in the box.
• SWAP THE DISC & CLEAN HOUSING IF NEEDED Each reusable housing is designed for 4 filter changes. Twist the housing open, remove the used disc, and insert a fresh one. Routine washing of the housing is not required. If visibly dirty, wash with warm water and mild, unscented soap, rinse thoroughly, and air-dry completely before reassembly. Never place a fresh filter disc into a wet or damp housing.
• DESIGNED FOR OPEN AIRFLOW The disc sits flat across the full 22mm opening, so the air path stays clear rather than pinched at the joint. Once it's fitted, read your pressure and leak numbers the way you normally would.
• WHAT'S IN THE BOX, AND WHAT THIS ISN'T 5 reusable twist-lock housings, 20 filter discs and an illustrated fitting card. This adds a layer of filtration inside your hose. It does not replace the intake filter inside your machine, so keep changing that on your manufacturer's schedule.
