NovoSleep DreamStation 2 Reusable Foam Filters, 3-Pack

The DreamStation 2 reusable foam filter is the pad every DreamStation 2 machine runs with, sitting at the air intake. It catches dust and pollen at that first stage, before that air ever reaches the blower inside the machine.

This is the Novosleep-made compatible version, built to the same shape as the Philips original foam filter. It fits every DreamStation 2 Auto CPAP and BiPAP model, and this listing ships three pads to a pack.

Key Features:

• Required filter: Every DreamStation 2 machine runs with this foam pad in place, whichever disposable filter you choose to add.
• First filtration stage: Positioned at the air intake, it catches larger particles like dust and pollen before air enters the machine.
• Reusable design: This foam pad is built to go back in the machine again and again, not thrown out after one use.
• Pack of three: Three pads ship in this pack, enough to rotate a fresh one in while another airs out.
• Compatible, not OEM: Novosleep builds this pad to the DreamStation 2's own shape, sold under its own brand rather than the Philips label.
• Fits the whole DS2 line: Every DreamStation 2 Auto CPAP and BiPAP model uses the same filter compartment, so one pad size fits them all.
• No tools needed: The pad presses into its slot and lifts back out by hand, with nothing to unscrew or pry loose.

Reach for this filter as part of routine DreamStation 2 upkeep, not only after a warning message, since a clogged intake is a common reason therapy pressure reads inconsistent overnight. Swap it out roughly twice a year to keep that airflow steady.

Note: This is a Novosleep-made compatible filter, not a Philips original, and it fits the DreamStation 2 only, not the original DreamStation.

Two filters, two jobs

This foam pad is required on every DreamStation 2, whichever disposable filter is added on top of it. It sits closest to the intake and is the first line of defense against dust and pollen.

The optional disposable ultra-fine filter clips onto the bottom of this pad for a second, finer layer, catching smaller particles and odors the foam alone would let through.

Cleaning and replacing

Rinse the pad under running water roughly every two weeks, working any visible dust free, then let it dry completely before reinstalling it in the machine.

Philips rates the design for about six months of nightly use before the foam itself should be replaced outright, sooner if it tears or the shape flattens.

A compatible part, not an OEM one

Novosleep manufactures this filter to match the DreamStation 2's own foam pad in shape and fit, rather than sourcing it from Philips directly.

It does the same intake job as the Philips original, and installs the same way, snapping into the same filter compartment.
