The Luna G3 Reusable Air Filter (12-Pack) is a washable coarse filter for the React Health Luna G3 — built to be rinsed clean and reused over many months. Traps dust, pet dander, pollen, and other airborne particles while keeping your machine running efficiently.
Designed for the React Health Luna G3 series. Not interchangeable with other CPAP brands.
Reusable filters (this listing) are washable, last longer per filter, and offer coarse particulate filtration — eco-friendly and cost-effective for everyday use. Ultra Fine filters (separate listing, HEPA-style) trap finer particles down to 0.3 microns — better for allergy sufferers or dusty environments. Both fit the same Luna G3 — switch between them as your needs change.
12 reusable Luna G3 air filters — a long-term supply at the recommended replacement schedule.
Rinse monthly: Wash gently with mild soap and water, then let air dry fully before putting it back.
Replace every 6 months (or sooner if visibly worn, torn, or no longer cleanable). At the recommended rinse-and-replace schedule, this 12-pack provides multiple years of supply.
