Hygiene & Maintenance: How Often Should You Clean or Replace Your Cannula & Filters?

Maintaining your oxygen concentrator in top working condition is essential—not just for extending the life of the machine, but also for protecting your respiratory health. A well-maintained unit ensures consistent oxygen delivery and minimizes the risk of infection, device malfunction, or reduced oxygen output.

Whether you're new to oxygen therapy or a long-time user, understanding proper hygiene and oxygen concentrator maintenance is crucial. In this blog, we'll dive into how often you should clean or replace your nasal cannula and filters, why it matters, and how Oxygensolve can help you stay safe and healthy.

Why Hygiene Matters in Oxygen Concentrator Use

Oxygen concentrators are healthcare devices used to deliver supplemental oxygen to people with respiratory conditions such as COPD, asthma, or long-term COVID-19 symptoms. Over time, components like nasal cannulas and filters can collect bacteria, dust, and moisture, which can lead to:

• Bacterial growth that poses health risks

• Reduced airflow due to clogged filters

• Skin irritation from dirty cannulas

• Unpleasant odors and poor air quality

Routine cleaning and replacement are essential components of oxygen concentrator maintenance and play a major role in the safe and effective use of these devices.

How Often Should You Clean or Replace Your Nasal Cannula?

Your nasal cannula is the soft plastic tubing that delivers oxygen directly into your nostrils. Since it is in constant contact with your skin and mucous membranes, it requires consistent care.

Daily Maintenance

• Wipe down the exterior tubing with a clean, damp cloth.

• Inspect for discoloration, cracks, or moisture build-up.

Weekly Cleaning

• Soak the cannula (if reusable) in a solution of mild soap and warm water.

• Rinse thoroughly and let it air dry completely.

⚠️ Important: Not all cannulas are reusable. Check your device manual or consult Oxygensolve to determine if yours is reusable.

Replacement Frequency

• Every 2 to 4 weeks for reusable cannulas

• Immediately if the cannula becomes stiff, discolored, or emits a foul odor

How Often Should You Clean or Replace Filters in Oxygen Concentrators?

Filters are responsible for cleaning the air before it's concentrated into pure oxygen. Dirty filters not only reduce the effectiveness of the machine but may also release contaminated air.

There are two common types of filters in oxygen concentrators:

1. External (Pre-) Filters

These catch larger particles such as dust and lint.

• Cleaning Frequency: Every week

  • Remove the filter

  • Rinse under warm running water

  • Let it air dry completely before reinserting

• Replacement Frequency: Every 3 to 6 months, or as specified by the manufacturer

2. Internal (HEPA or Bacteria) Filters

These filters catch finer particles and bacteria.

• Cleaning Frequency: Not recommended—these are usually non-washable

• Replacement Frequency: Every 6 to 12 months, depending on usage and model

Always consult your user manual or contact Oxygensolve to confirm the filter type and replacement schedule specific to your device.

7 Signs It’s Time to Replace Cannulas or Filters

1. Yellowing or discoloration

2. Cracks or stiffness in tubing

3. Dust accumulation or clogging

4. Unusual machine noises

5. Decreased oxygen flow rate

6. Unpleasant smell during use

7. Visible mold or condensation buildup

Tips for Better Oxygen Concentrator Maintenance

• Keep your oxygen machine in a clean, dry, well-ventilated area.

• Avoid placing the unit near pets or dusty surfaces.

• Check tubing and filters as part of your weekly routine.

• Use only manufacturer-approved parts for replacements.

• Schedule a professional maintenance check every 6–12 months.
