NovoSleep DreamStation 2 Ultra-Fine Filters, 6-Pack

A DreamStation 2 pulls in bedroom air through two filter stages stacked together, and this piece holds the outer position, fitted against the machine's required foam pad rather than replacing it. Novosleep engineers it to occupy that exact same spot.

This is the compatible version rather than the Philips original, built by an independent manufacturer to the same measurements. It ships as a six-count pack only, unlike the original's one, two, and six count options.

Key Features:

• Same fit as OEM: Novosleep engineers this piece to seat in the identical spot the Philips original occupies, against the required foam pad.
• Second-stage duty: Positioned after the foam stage, it is designed to pick up whatever finer particles and odors get past that first layer.
• About a month per filter: Figure on roughly a month of nightly use before this piece should come out and a fresh one goes in.
• Independent manufacturer: An outside manufacturer, not Philips, produces this filter to the DreamStation 2's exact measurements and fit.
• Six-count only: This listing ships as a single six-count pack, with no smaller count offered the way the original comes in.
• Half a year of coverage: Six filters at roughly one swap a month works out to about six months of coverage per pack.

A dustier room, a smoky evening, or the calendar hitting a month are all reasons to pull this filter, since a clogged one forces the machine's blower to work harder for the same output. The swap itself takes only a few seconds.

Note: This is a Novosleep compatible filter, not a Philips original, sold only as a six-count pack rather than the smaller options Philips offers.

The outer filtration stage

Air pulled into a DreamStation 2 first crosses the required foam pad, which is built to stop dust and pollen before either ever reaches the machine's blower.

This disposable piece sits directly against that pad on the outside, positioned to intercept whatever the foam weave was not tight enough to hold back, mainly smoke odor and the smallest particles.

A once-a-month part

Novosleep designs this piece for roughly thirty nights of use, after which its fibers have generally picked up as much as they are going to hold.

Unlike the foam pad it sits against, there is no cycle of drying out and reinstalling this piece. Once it has done a month of work, it gets thrown out and replaced.

Six filters, one manufacturer

A manufacturer outside the Philips supply chain builds this piece to those same specifications, rather than under license, so nothing here carries the Philips name.

The six filters in this pack are identical to one another, which is also why the listing offers no smaller count the way the Philips original does.

Here's everything that comes in the box.
