Build a simple CPAP replacement calendar for masks, cushions, filters, tubing, headgear, humidifier chambers, and machines. Print your checklist and avoid guessing when supplies are due.
Pick each CPAP item you use, enter when you last replaced it, then add it to your personal replacement calendar.
Nasal cushion is usually replaced every month. If last replaced May 27, 2026, it is due Jun 26, 2026.
Add the supplies you use to calculate replacement dates.
Choose an item on the left, enter when you last replaced it, and your due dates will appear here.
Many CPAP supply schedules use monthly cushions or nasal pillows, filters every few weeks, tubing and mask frames around every three months, and headgear or humidifier chambers around every six months. Your actual schedule can vary by equipment, usage, cleaning, insurer, and supplier.
Charts are easy to forget. A calculator turns replacement intervals into dates you can print, save, or later export into reminders. That is the wedge: useful utility first, content and monetization second.
No. This site is informational planning only. Always verify replacement timing, eligibility, and medical needs with your doctor, DME supplier, insurance plan, Medicare rules, and product manufacturer.
The defaults below reflect intervals commonly published by DME suppliers and referenced against the Medicare PAP supply schedule. They are starting points, not prescriptions. Your prescribed plan, manufacturer instructions for use, and how the equipment performs day to day should override any generic chart.
The cost estimate above changes with your planning mode because it reflects an approximate patient share, not the supplier's full retail price. Your actual copay, deductible, and supplier pricing will differ.
Use the calculator for dates, then read the focused guides for common replacement timing, wear signs, cost planning, and checklist structure.
