Autumn CPAP Tune-Up: Prepare Your Therapy for Winter Comfort
Simple filter, humidifier and nose-care checks to help you breathe easier through colder months
Preparing your CPAP therapy for winter
As temperatures drop, cooler and drier air can make CPAP therapy feel less comfortable, particularly for the nose and sinuses. A simple autumn tune-up, including checking filters, adjusting humidification and supporting nasal health, can help you stay comfortable and consistent with therapy through winter. Small changes now may prevent irritation,
congestion and disrupted sleep later.
As the weather cools and colds, flu and sinus issues begin circulating again, autumn is an ideal time to give your CPAP setup a quick tune-up so you’re ready for winter.
Lower temperatures, drier air and increased indoor heating can all affect how CPAP therapy feels. A setup that worked well over summer may suddenly feel dry, stuffy or uncomfortable. The good news is that a few simple checks can make a meaningful difference.
Why cooler months are tougher on your nose
During autumn and winter, the air is typically cooler and less humid, particularly once heaters are running
overnight. This can dry out the delicate lining of the nose and sinuses, making them more prone to irritation.
When a cold, flu or sinus infection is added to the mix, nasal congestion and dryness can increase further.
For CPAP users, this may show up as a blocked nose,
increased mask leaks, mouth breathing or discomfort that makes therapy harder to tolerate.
Filters: keeping winter dust and irritants at bay
Your CPAP filter is the first line of defence between the air in your room and your airway. Its role is to trap dust, fine particles and other irritants before they reach your lungs.
Over time, filters naturally clog. In winter, when windows are closed and indoor air circulation changes, this can happen more quickly.
An autumn filter check is a sensible habit. This includes:
- Checking for visible greying, dust build-up or damage and replacing filters that look worn
- Following the recommended replacement schedule for your device, often monthly for disposable fine filters
- Keeping spare filters on hand so you can change them promptly, particularly if you’ve been unwell
Regular filter replacement supports consistent airflow and helps reduce irritation during cold and flu season.
Humidifiers: moisture for dry, sore airways
Cold, dry air combined with pressurised CPAP airflow can dry out the nose and throat. This may lead to soreness, congestion or thicker mucus that’s harder to clear.
Heated humidifiers and heated tubing add warmth and moisture to the air you breathe during therapy. For many people, this helps soothe irritated airways and improve overall comfort.
As part of an autumn tune-up:
- Empty and refill the water chamber daily, and clean it regularly
- Adjust humidity settings gradually if you’re waking with a dry or blocked nose
- If you notice condensation in the mask or tubing, reduce the setting slightly or consider heated tubing to stabilise the temperature
Using humidification consistently through winter can help reduce nasal and throat symptoms and support comfortable, ongoing therapy.
Nose and sinus care: small habits, big comfort
Even with good humidification, a cold or sinus infection can make breathing through a nasal mask difficult.
Simple nose-care habits can help:
- Using a preservative-free saline spray or rinse before bed to gently moisturise and clear the nasal passages
- Speaking with your clinic about temporarily using a full-face mask if nasal congestion makes nasal breathing uncomfortable
- Cleaning your mask, tubing and humidifier chamber daily when you’re unwell to reduce irritation and support hygiene
For many people, continuing CPAP therapy during a cold or flu, with a few comfort-focused adjustments, supports better sleep and a smoother recovery.
Nose and sinus care: small habits, big comfort
As the air cools and becomes drier, CPAP therapy can feel different. A few small adjustments now can help you stay comfortable and consistent through winter.
