Philips DreamStation 2 Disposable Ultra-Fine Filter

The Philips DreamStation 2 disposable ultra-fine filter is the second stage in the machine's filtration system, clipping onto the bottom of the required foam filter. It targets the finer particles that the foam stage alone would let through, including smoke and other airborne odors.

This is the genuine Philips Respironics part, not a compatible version from another brand, and it ships in three pack sizes, one, two, or six filters. Whichever size you order, it fits every DreamStation 2 Auto CPAP and BiPAP model the same way.

Key Features:

• Second filtration stage: Clips onto the bottom of the required foam filter to add a finer, second layer of protection.
• Blocks smoke and odor: Catches finer particles like tobacco smoke and airborne odors that the foam stage alone lets through.
• Thirty day cadence: Philips rates this filter for about thirty days of use before it should be swapped for a new one.
• Genuine Philips part: Carries the original Philips Respironics part number, not a compatible replacement made by another brand.
• Three pack sizes: Ships as one, two, or six filters, with the identical part inside every pack size.
• Not a standalone filter: Works only alongside the required foam filter, and is never installed in the machine on its own.

Replace this filter about every thirty days, sooner if the air around your machine turns smoky or dusty, since a clogged filter forces the blower to work harder for the same pressure. It clips on and off in seconds, no tools required.

Note: This filter fits the DreamStation 2 only, not the original DreamStation, and installs alongside the required foam filter rather than replacing it.

A second, finer layer

Philips builds the DreamStation 2 around two filter stages stacked together, and this disposable piece is the outer one, seated against the required foam pad rather than swapped in for it.

Dust and pollen get caught earlier by the foam stage, leaving this layer to pick up what is left, smoke particles and other odors small enough to pass straight through foam alone.

Replacing it

A month of nightly use is roughly what Philips designs this piece to handle before its fibers start losing their grip on incoming particles, so a routine swap keeps performance where it started.

There is no cleaning step available the way there is with the foam pad beneath it: once this piece looks gray or the room feels dustier than usual, a new one goes in instead.

The genuine Philips part

Every unit in this listing carries Philips Respironics' own part markings, sourced the same way the filter already inside a brand new DreamStation 2 was sourced, rather than through a third party.

Buyers choosing between the one, two, and six count options are choosing quantity only, since the piece inside each box is identical regardless of pack size.

Here's everything that comes in the box.

• Six disposable ultra-fine filters (Pack of 6 option)
• Two disposable ultra-fine filters (Pack of 2 option)
• One disposable ultra-fine filter (Pack of 1 option)
