The Luna G3 Disposable Ultra Fine Filters (12-Pack) are HEPA-style filters that trap airborne particles down to 0.3 microns — capturing 99.97% of dust, pollen, pet dander, bacteria, and other irritants before they reach your therapy air. Designed for the React Health Luna G3, with a 12-pack supply for ongoing replacement.
Compatible with React Health Luna G3 CPAP and BiPAP machines. Not interchangeable with other CPAP brands.
Ultra Fine filters (this listing) are HEPA-style — trap fine particles, allergens, and bacteria. Ideal for users with allergies, asthma, or in urban/dusty environments. Reusable filters (separate listing) are washable and last longer per filter, but provide coarser filtration. Both fit the same Luna G3 — switch between them as your environment or needs change.
12 disposable Ultra Fine filters — approximately 6 months of supply at bi-weekly replacement.
Replace each filter every 7 to 14 days. Replace sooner if the filter is visibly soiled or you're in a high-allergen environment.
