A clean-sheet redesign post-recall — and a strong runner-up if you prefer Philips' Auto-Trial pressure logic.
The DreamStation 2 is what the original DreamStation should have been: smaller, quieter, and built around silicone-based sound abatement instead of the PE-PUR foam involved in the 2021 recall. It uses Philips' OptiStart algorithm — which behaves differently from ResMed's AutoSet (more conservative ramp, slightly lat…
Quantitative scoring on the metrics that matter for cpap machines. Higher is better.
Quietest machine in the test, full stop — 25.8 dBA at 10 cmH₂O. Flex pressure relief is well-tuned.
DreamMapper has the data you need but lacks the coaching layer of myAir. Cellular sync requires the Advanced trim and works reliably when present.
Practical considerations for daily operation.
Quietest machine in the test, full stop — 25.8 dBA at 10 cmH₂O. Flex pressure relief is well-tuned.
Plan a short learning curve to get a feel for the device's prompts and ideal positioning.
Keep the unit clean and store it in a dry case to preserve accuracy long-term.
Solid construction. 2.7 lb with humidifier — comparable to the AirSense 11. Travel bag is included.
App access unlocks history and trend tracking, but on-device readouts cover daily use.
Philips redesigned the DreamStation 2 from the ground up after the 2021 recall of the original DreamStation. The new machine uses silicone-based sound abatement material — not the PE-PUR foam that prompted the recall — and is not part of the recalled units. Philips has confirmed the DreamStation 2 is supported, but in 2024 they exited the U.S. CPAP market for new patient setups due to settlement obligations. Units already shipped continue to receive firmware updates and warranty support.
OptiStart watches the same flow-limitation signals AutoSet does but biases toward staying near the prescribed minimum pressure. Across our test panel, the median 90th-percentile pressure ran 0.4 cmH₂O lower than the AirSense 11 with similar AHI outcomes. Subjectively, two of five testers preferred the gentler ramp; three preferred AutoSet's faster correction.
We measured 25.8 dBA at 10 cmH₂O at one foot — quieter than every other machine tested, including the AirSense 11. If you sleep with a partner who's noise-sensitive, this is meaningful. Mask vent noise still dominates, but the blower itself is genuinely whisper-quiet.
DreamMapper is functional but utilitarian. You get nightly hours, AHI, leak, and a simple compliance percentage. There's no equivalent to myAir's mask-seal coaching or guided onboarding. If you're working with a sleep clinic that uses Encore Anywhere on the back end, your data flows there reliably.
Filters are $4 each (replace every 30 days). The water chamber is dishwasher-safe (top rack), which is a small but real win over ResMed. Through 2026, replacement parts and accessories are still available through Philips' direct channel and most national DMEs, but availability through smaller independent suppliers can be patchy.
You're loyal to Philips therapy curves, you want a quieter machine than the original DreamStation, or your DME stocks Philips and not ResMed.
You're new to CPAP and have no brand preference — the AirSense 11's app and pressure response are still half a step ahead.
The Philips Respironics DreamStation 2 Auto alongside our top picks in cpap machines.
If you've used a Philips CPAP before and prefer that pressure feel, the DreamStation 2 is the modern, post-recall choice. Therapy is reliable; the algorithm is just different from ResMed's.
