Simple, tool-free filter replacement requiring no technical knowledge

Sold in packs of 2 filters for convenient back-to-back replacement cycles

Compact design suited to the Z1 and Z2's travel-focused build

HDM Z1 and Z2 Auto Travel CPAP users due for a scheduled filter replacement

Frequent travellers who use their Z1 or Z2 regularly and want to maintain consistent filter replacement on the road

Those who travel to dusty environments, high-pollen areas, or locations with higher than average airborne particulate levels

Z1 and Z2 users who want to keep spare filters in their travel bag so a replacement is always available away from home

Replacement schedule: Replace your Z1 or Z2 filter every 1 to 2 months under normal use. If you travel frequently to dusty or high-particulate environments, inspect the filter monthly and replace sooner if it appears visibly grey or clogged.

Pack of 2: Each pack contains 2 filters, providing two full replacement cycles. For most patients using their travel machine regularly, one pack covers approximately 2 to 4 months of use.

Travel tip: Always pack at least one spare filter whenever you travel with your Z1 or Z2. A fresh filter takes up virtually no space in your travel case and ensures you can replace on schedule wherever you are.

Visual inspection: Check your filter at each scheduled replacement. If it appears visibly discoloured or clogged before the scheduled date, replace it immediately rather than waiting.

Do not wash: Z1 and Z2 filters are disposable and must not be washed or reused. Washing damages the filtration media and renders the filter ineffective.

Not the HME: These are machine air filters for the Z1 and Z2 device itself and are not the HME waterless humidification inserts. If you need HME replacements, see the HME Filters listing in the CPAP Accessories section.

Z1 and Z2 machine filters are disposable and must not be washed, rinsed, or reused. Replace on the recommended schedule or sooner if visibly discoloured or clogged. Discard used filters and install a fresh replacement following the instructions in your Z1 or Z2 user manual.

Contact CPAP Machines Canada to reorder and confirm compatibility with your specific Z1 or Z2 model.

Q: Are these filters compatible with both the Z1 and Z2?
A: Yes. These replacement filters are compatible with both the HDM Z1 Travel CPAP and the HDM Z2 Auto Travel CPAP machines. Contact CPAP Machines Canada to confirm compatibility with your specific model before ordering if you are unsure.

Q: How many filters come in a pack?
A: Each pack contains 2 filters, providing two full replacement cycles. For most patients replacing filters every 1 to 2 months, one pack covers approximately 2 to 4 months of use depending on your replacement frequency.

Q: How often should I replace my Z1 or Z2 filter?
A: Replace your filter every 1 to 2 months under normal use. If you travel frequently to dusty environments or areas with high pollen or particulate levels, inspect the filter monthly and replace sooner if it appears visibly grey or clogged before the scheduled date.

Q: Are these the same as the HME waterless humidification inserts?
A: No. These are machine air filters for the Z1 and Z2 device itself and are entirely separate from the HME waterless humidification inserts. The machine filter sits inside the device and filters incoming air before it enters the motor. The HME is a separate humidification accessory that attaches between the mask and tubing. Both require regular replacement but they are different products. If you need HME replacements, see the HME Filters listing in the CPAP Accessories section.

Q: Can I wash and reuse the Z1 or Z2 filter?
A: No. Z1 and Z2 machine filters are disposable and must not be washed or reused. Washing damages the filtration media and renders the filter ineffective, leaving your machine drawing unfiltered air during therapy. Always replace with a fresh filter on the recommended schedule.

Q: What happens if I travel without replacing my filter on schedule?
A: Running your Z1 or Z2 with a clogged or overdue filter restricts airflow to the motor, reduces therapy pressure accuracy, and allows unfiltered particles into the air you breathe during therapy. We recommend always keeping at least one spare filter in your travel bag so you can replace on schedule wherever you are.

Q: How do I replace the filter on my Z1 or Z2?
A: Filter replacement on the Z1 and Z2 is tool-free. Refer to your machine's user manual for step-by-step instructions. If you need assistance, contact CPAP Machines Canada and our sleep professionals will guide you through the process.
