How to Track CPAP Equipment Replacement (Without a Spreadsheet)

May 27, 2026·5 min read

Educational content, not medical advice. This article compares supply-tracking methods. Your DME supplier and sleep specialist are the right people to advise on your specific equipment schedule. Full terms.

Knowing when to replace your CPAP cushion, filter, mask, headgear, tubing, and water chamber is one thing. Actually remembering across 11 different replacement intervals stretched across the year is another. Here are the three approaches CPAP users typically take — and what each one is actually good for.

If you're looking for the underlying schedule itself, see How Often to Replace Each CPAP Supply.

1. Your manufacturer's app

ResMed myAir and Philips DreamMapper are the free apps that come with their respective CPAP machines. They focus on therapy data (AHI, usage hours, leak rate) and provide encouragement around therapy adherence.

What they do well

• Show your nightly therapy data automatically — no manual logging
• Track usage hours toward insurance compliance thresholds
• Free, no setup beyond pairing your machine

Where they fall short for replacement tracking

• Neither tracks when to replace your supplies — they don't know your cushion was new on March 1st
• If you switch CPAP brands (ResMed to Philips or vice versa), you start over with no history
• You can't log inventory (how many spare cushions you have on hand)
• Limited cleaning task tracking

Best for: people who only want to see therapy data, don't manage their own supplies, and have a DME supplier who auto-ships on schedule.

2. A spreadsheet (or paper calendar)

The DIY approach — a Google Sheet or paper calendar with rows for each part, columns for "last replaced" and "next due."

What it does well

• Total flexibility — track whatever fields matter to you
• Free, no account required, no platform lock-in
• Works the same way regardless of CPAP brand

Where it falls short

• Maintenance fatigue. You'll update it for 3 weeks. Then you'll skip a week. Then a month. Then you'll forget you had a spreadsheet.
• No proactive reminders — you have to remember to check the sheet
• No inventory tracking unless you build it yourself
• Doesn't follow you to your phone in a way that's actually quick to check

Spreadsheets work well for organized people who already use spreadsheets daily. For everyone else, they work for a month and then quietly die.

3. A dedicated CPAP tracker app

Apps purpose-built for CPAP supply management. They sit on your phone, calculate replacement dates from the date you last replaced each item, send a notification when something is due, and (the better ones) also handle cleaning tasks and AHI logging in the same place.

What they do well

• Proactive reminders. The app notifies you a few days before each replacement is due, so you can order in time
• Survives CPAP brand switches — your replacement history stays with you
• Most include cleaning schedule tracking — daily/weekly/monthly tasks
• Some track on-hand inventory and remind you to reorder before you run out
• iCloud sync keeps the data on every device (iPhone, iPad, Apple Watch)

What to look for

Not all tracker apps are equal. The features that actually matter long-term:

• Free tier that's actually usable. Some apps lock basic tracking behind a subscription. Look for free tracking of at least your essential consumables.
• Inventory tracking. The newer feature, only a few apps support it. Knowing you have 2 cushions left so you can reorder before running out matters more than the replacement date itself.
• Apple Watch integration. Quickly checking equipment status from your wrist beats unlocking your phone.
• Cleaning schedule tracking. Daily/weekly/monthly tasks based on the equipment you actually have, not a generic checklist.
• AHI logging. Bonus if it lets you log AHI alongside equipment, so you can connect a worn cushion to a rising AHI trend.
• One-time purchase Pro. Subscription fatigue is real. Find an app where the upgrade is a one-time payment, not monthly forever.
• iCloud sync. Your data lives on your device but syncs to your other devices. No third-party server holding your health data.

The honest pitch

We built CPAP Tracker with exactly these requirements. It's the app behind this blog. Free tier covers replacement schedules for up to 5 consumables, cleaning tasks, AHI logging, Apple Health integration, and the Apple Watch app. Pro (one-time purchase, no subscription) unlocks unlimited consumables, iCloud sync across iPhone/iPad/Apple Watch, low-stock reorder push reminders, PDF export, and an ad-free experience.

If you'd rather use one of the alternatives, no hard feelings — the manufacturer apps and spreadsheets are real options. But if you want one place that handles replacement dates, inventory, cleaning, and AHI together, that's what we built.
