Bacterial Filter

• Inline bacterial and viral filtration for CPAP therapy setups
• Fits between standard CPAP tubing and mask elbow connections
• 22mm inner diameter inlet for standard CPAP tubing connection
• 15mm inner diameter / 22mm outer diameter outlet for mask elbow connection
• Adds an additional layer of filtration beyond the built-in machine filter
• Tool-free installation — attaches directly inline with your existing tubing and mask setup
• Suitable for patients who want enhanced air filtration during sleep apnea therapy

CPAP users who want an additional layer of bacterial and viral filtration in their therapy setup

Patients with respiratory sensitivities, allergies, or compromised immune systems who benefit from enhanced inline filtration

Those recovering from illness who want to reduce the risk of reintroducing bacteria or viral particles during therapy

Clinical settings where additional inline filtration between shared tubing components is required

CPAP users who want supplementary filtration beyond what their machine's built-in filter provides

Installation: The Sunmed Bacterial and Viral Filter installs inline between your CPAP tubing and your mask elbow connection. Connect the 22mm inlet to your CPAP tubing and the outlet to your mask elbow. Ensure both connections are secure before starting therapy to prevent air leaking around the filter connection points.

Replacement schedule: Replace your inline filter regularly to maintain effective bacterial and viral filtration. A filter that has been in use for an extended period may become saturated or clogged, reducing airflow and filtration effectiveness. Contact CPAP Machines Canada for guidance on recommended replacement frequency for this filter.

Supplementary filtration: The Sunmed inline filter is designed to work alongside your machine's existing built-in filter, not as a replacement for it. Continue replacing your machine filter on the recommended monthly schedule in addition to using the inline filter.

Airflow resistance: All inline filters add a small degree of airflow resistance to your CPAP setup. This is normal and expected. If you notice a significant reduction in therapy pressure or comfort after installing the filter, contact CPAP Machines Canada for guidance.

Compatibility: This filter is designed for standard 22mm CPAP tubing connections. Contact CPAP Machines Canada to confirm compatibility with your specific tubing and mask elbow before ordering if you are unsure.

The Sunmed Bacterial and Viral Filter is a disposable inline filtration accessory and must not be washed or reused. Replace on a regular schedule to maintain effective filtration. Discard used filters and install a fresh replacement. Do not attempt to clean the filter media with water, soap, or any cleaning solution.

Continue cleaning your CPAP mask, tubing, and water chamber on the regular schedule detailed in the full maintenance guide below.

Q: Where does this filter install in my CPAP setup?
A: The Sunmed Bacterial and Viral Filter installs inline between your CPAP tubing and your mask elbow connection. The 22mm inlet connects to your CPAP tubing and the outlet connects to your mask elbow. No tools are required. Ensure both connections are secure before starting therapy.

Q: Does this filter replace my machine's built-in filter?
A: No. The Sunmed inline filter is a supplementary filtration accessory designed to work alongside your machine's existing built-in filter, not as a replacement for it. Continue replacing your machine's built-in filter on the recommended monthly schedule in addition to using the inline filter.

Q: Who benefits most from using an inline bacterial and viral filter?
A: Inline bacterial and viral filters are particularly beneficial for patients with respiratory sensitivities, allergies, or compromised immune systems who want an additional layer of filtration beyond their machine's standard filter. They are also commonly used by patients recovering from illness or in clinical settings where enhanced inline filtration is required.

Q: Will this filter affect my therapy pressure?
A: All inline filters add a small degree of airflow resistance to your CPAP circuit, which is normal and expected. For most patients this is not noticeable during therapy. If you experience a meaningful reduction in therapy comfort or pressure after installing the filter, contact CPAP Machines Canada for guidance.

Q: Is this filter compatible with my CPAP machine and mask?
A: The Sunmed filter is designed for standard 22mm CPAP tubing connections, which are used by the vast majority of CPAP machines and masks from all major manufacturers. Contact CPAP Machines Canada to confirm compatibility with your specific tubing and mask elbow configuration before ordering if you are unsure.

Q: How often should I replace the inline filter?
A: Contact CPAP Machines Canada for specific replacement frequency guidance for this filter. As a general principle, replace the filter when it appears visibly discoloured or clogged, or if you notice increased airflow resistance during therapy. Regular replacement maintains effective filtration and prevents the filter from restricting airflow.

Q: Can I wash and reuse this filter?
A: No. The Sunmed Bacterial and Viral Filter is a disposable accessory and must not be washed or reused. Washing will damage the filtration media and render the filter ineffective. Always replace with a fresh filter on the recommended schedule.
