Dreamstation DS Disposable Ultra Fine Filters – 2pack

The DreamStation Disposable Ultra-Fine Filters (2‑pack) are essential single-use filters designed specifically for Philips Respironics DreamStation and DreamStation 2 CPAP/BiPAP machines. Housed in a light-blue plastic frame and made of finely blended synthetic polyester fibers, these filters trap ultra-fine particles such as dust, pollen, smoke, and other allergens—offering up to 95 % filtration efficiency for particles sized 0.5 – 0.7 microns They are intended to be used in conjunction with the washable reusable pollen filter: the reusable filter captures larger debris, while the disposable ultra-fine filter provides an extra layer of protection for both the user and the device . Each filter is designed for one-month use and cannot be cleaned—regular replacement is essential to maintain optimal air quality and machine performance  For best results, it’s recommended to replace these filters every 30 nights, or sooner if you live in a dusty environment or have pets. With a convenient 2‑pack, it’s easy to ensure uninterrupted, clean, and comfortable CPAP therapy.

Installation Steps

1. Power down and open the filter slot
   Turn off your DreamStation (Original series), open the side/back filter access panel, and slide out the washable foam pollen filter (dark/blue)

2. Attach the ultra-fine filter
   Snap the light-blue disposable ultra-fine filter onto the base of the foam filter. The white filter media is permanently attached to the light-blue frame—don’t try to separate them

3. Reinstall both filters together
   Insert the foam-and-ultra-fine filter assembly back into the machine, ensuring a snug fit .
