Exceleron Medical CPAP Filters

If you run a CPAP or BiPAP machine, the filter is the small part you can't afford to overlook. Exceleron Medical produces disposable replacement filters engineered to fit a wide range of popular sleep therapy devices, keeping the air you breathe overnight clean and free of dust, pollen, and other airborne particles.

The most common question buyers ask is simple: which filter fits my machine? Exceleron's line is organized around specific device families, so matching is straightforward. The Felt Pollen Filter for S9 (CF-36850-2) and the Ultra Fine Blue/White Filter for S8 (CF-33916-2) cover ResMed's popular S-series platforms. Philips Respironics users have several options, including the Ultrafine CPAP Filter for System One (CF-1029331-2) and the Ultra Fine Filter for the RemStar Legacy (CF-1005945-2). For Fisher & Paykel machines, the Ultra Fine Filter for HC230, HC240, and HC600 series (CF-900HC240-2) is the direct match.

These are disposable, single-use filters sold in convenient two-packs. The distinction worth knowing: coarse felt pollen filters (typically gray or black, and reusable-style) trap larger debris, while ultra-fine filters (the blue/white or white foam-style inserts) capture much smaller particles for people sensitive to fine dust and allergens. Many machines use both types together. Because they're inexpensive, most manufacturers recommend replacing the fine filter roughly every two weeks to a month, and sooner if it looks discolored — a clogged filter makes your device work harder and can degrade air quality.

Keeping a spare pack on hand means you never have to skip a night of therapy. Exceleron filters are built as cost-effective replacements for the OEM originals, so you can maintain your equipment without paying a premium for branded stock.
