CPAP mask tracking in Apnealytics

Your machine records how well your mask sealed every night, but it does not know which mask you wore. Apnealytics does. Pick your mask from a catalog of 62, and CPAP mask tracking turns your leak data into Mask Analytics: seal, AHI and usage per mask, so you can see which one actually works for you, and when its cushion is due.

How mask tracking works

Add your mask
Browse the Gear catalog by brand, then type, then size, or search by name. Each mask has a photo and a detail page. If yours is not listed, add it with your own photo.
Set the date you started wearing it
Every night from that date is attributed to that mask until you switch.
Import as usual
Your machine's leak and AHI data lands on each night as always; Apnealytics joins it to the mask you had on.
Open Mask Analytics
For each mask you have used, you see its seal score, average AHI and average usage, side by side.

What Mask Analytics shows

Seal
Built from leak P95, the 95th-percentile leak across the night. Leak P95 tells you how bad leak got during a sustained stretch, which is more useful than an average that a good first half can hide. A mask with a lower leak P95 across many nights has a better seal for your face.
AHI per mask
Average machine-estimated AHI across the nights you wore each mask. A mask that lets your mouth fall open may show a higher AHI even with a good-looking seal number.
Usage per mask
Average hours per night. A mask you take off at 3 a.m. shows up here, and it is often the most honest comfort measure you have.
Nights and span
How many nights each mask has, and over what dates, so you know whether a comparison rests on three nights or three hundred.

Replacement reminders

Cushions, pillows, filters and tubing wear out on a schedule, and a worn cushion is one of the most common reasons leak creeps up. Set a replacement interval for each part when you add it, and Apnealytics reminds you when it is due. Push notifications on the phone apps never show health numbers on the lock screen.

The three mask types

Each type page explains who it suits, fit tips, popular models and what Mask Analytics shows.

Type	Covers	Suits	Typical leak signature
Nasal	Nose only, cushion or cradle	Nose breathers, side sleepers	Low and steady; rises if mouth opens
Full face	Nose and mouth	Mouth breathers, higher pressures, congestion	Higher baseline; spikes with position changes
Nasal pillows	Seals at the nostrils	Minimal contact, glasses wearers, facial hair	Very low when seated; sensitive to pillow size

Masks in the catalog

The catalog includes current models from ResMed (AirFit N30i, N20, F20, F30i, P30i, P10 and others), Philips Respironics (DreamWear in nasal, pillows and full face), Fisher & Paykel (Evora, Eson 2, Vitera, Brevida), and others, 62 in all with photos and part lists. Masks work with any machine that has a standard 22 mm tube connection; AirMini-specific versions are listed separately. Mask tracking does not depend on your machine being supported: a DreamStation owner can track masks today and the seal data fills in from the nights you import.

Mask type and your machine's leak numbers

ResMed machines ask you to set the mask type (Pillows, Nasal, Full Face) because it changes how leak is calculated and what counts as normal. When you switch mask type in Apnealytics, the "What changed?" panel marks the switch so a step in leak P95 is explained rather than alarming. Read more in mask seal and leak explained.

FAQ

Questions people ask

Help center →

How does Apnealytics know which CPAP mask I am wearing?

You tell it once. Add the mask from the catalog of 62, set the start date, and every night from then on is attributed to that mask. When you switch, add the new one and the attribution changes from that date. Your machine's leak and AHI data is then compared per mask in Mask Analytics.

What is leak P95 and why does Apnealytics use it?

Leak P95 is the leak level that 95 percent of the night stayed below, so it reflects your worst sustained stretch rather than an average. It is the standard measure for judging mask seal because a good average can hide an hour of heavy leak. Apnealytics shows it on every night and per mask.

Does mask tracking work if my machine is not supported yet?

Yes for the catalog, replacement reminders and gear history. Seal, AHI and usage per mask need nightly data, so they fill in from the nights you import, on any supported machine. Owners of machines on the waitlist can set up their gear now.

How often should I replace my CPAP mask cushion?

Follow your supplier's guidance; a common pattern is cushions and pillows monthly, filters monthly or fortnightly, and frames and tubing every few months, but it varies by product and insurer. Apnealytics lets you set your own interval per part and reminds you when it is due.

Can Mask Analytics tell me which mask to buy?

It shows you what happened with each mask you have actually worn: seal, AHI, usage, over how many nights. That is strong evidence for a conversation with your equipment supplier or clinician. It is not a recommendation engine, and we do not take payment from mask manufacturers.
