resplabs CPAP Filters Compatible with Philips DreamStation 1 Machine 18 Disposable & 9 Reusable Filter Replacements 27 Pack

BOTH FILTER TYPES IN ONE PACK: Your DreamStation 1 requires TWO different filters — a disposable pollen filter (baby blue) and a reusable foam filter (darker blue). This pack includes both: 18 disposable and 9 reusable filters. No need to buy them separately. IMPORTANT: These filters fit DreamStation 1 ONLY. They will NOT fit the newer DreamStation 2, which uses different dimensions and a gray filter frame. DISPOSABLE FILTER — REPLACE EVERY 2 WEEKS: The baby blue pollen filters capture fine particles like dust, pollen, and pet dander before they enter your airway. Replace every 2 weeks — or weekly if you have pets, allergies, or live in a dusty environment. When the filter changes from baby blue to gray, it has done its job. REUSABLE FILTER — WASH MONTHLY, REPLACE EVERY 6 MONTHS: The darker blue foam filters handle larger particles and debris. Rinse with warm water once a month, let air dry completely before reinstalling. Replace the foam filter every 6 months or when it loses its shape. Both filter types must be installed for your machine to work properly. EASY SLIDE-IN INSTALLATION: Open the filter cover on the back of your DreamStation 1. The reusable foam filter goes in first (closest to the machine), then the disposable pollen filter on top. No tools needed — takes less than a minute. Your machine may display a filter replacement reminder to help you stay on schedule. STOCK UP FOR OVER A YEAR: 27 filters (18 disposable + 9 reusable) keeps you covered for well over a year at the recommended replacement schedule. resplabs is a trusted CPAP accessory brand with over 11,000 verified reviews across our CPAP product line.
