You’re Overdue: The Shocking Truth About Expired CPAP Filters

CPAP Filters

Table of Contents

Let’s face it, most CPAP users are not changing their filters as often as they should. Whether it’s forgetfulness or simply not knowing the risk, expired CPAP parts, especially filters, can cause more harm than you think. Dirty filters can compromise your therapy, expose you to allergens, and even shorten the life of your machine.

If you’ve been putting off a CPAP filter replacement, it’s time to rethink that decision. Proper filter maintenance isn’t just a technical task, it’s essential for your health. In this blog, we’ll answer the most common filter-related questions, and show you how to stay on top of CPAP care without the stress.

How often should I replace my CPAP filter?

One of the most frequently asked questions is: how often to change CPAP filter components?

The answer depends on the type:

  • Disposable (fine) filters: Replace every 2–4 weeks
  • Reusable (foam) filters: Clean weekly and replace every 3 months

Environmental factors matter, too. If you live with pets, smoke, or experience seasonal allergies, you may need to change your filters more frequently. A clogged or dirty filter means your CPAP machine works harder and that’s not a good thing.
Need help staying on schedule? Many CPAP users now rely on CPAP filter subscription services from providers like cpapRX, which take the guesswork out of it.

What happens if you use an expired CPAP filter?

Ignoring filter changes might seem harmless, but it can actually undermine your therapy. When a filter is expired:

  • Air quality drops – You breathe in more dust, allergens, and bacteria
  • Your machine strains – Overworked motors are more likely to fail early
  • Infections may increase – Especially in those with weakened immune systems

Simply put, expired CPAP parts risk your health and your equipment. Filters are your first line of defense against harmful airborne particles, don’t let them go neglected.

For those who want peace of mind, cpapRX offers both one-time and recurring filter options, so your equipment never goes unprotected.
