Maintenance for Kingon P2 Portable Oxygen Concentrators
Maintenance for P2-E, P2-E6 & P2-E7 Models
If you’ve recently purchased, or are considering purchasing, a Kingon P2 Portable Oxygen Concentrator, understanding how to properly maintain your device is essential.
Regular maintenance not only ensures your device performs reliably, but also helps extend its lifespan, protect your investment, and give you confidence in your oxygen therapy wherever life takes you.
This guide walks you through simple, practical care steps you can follow at home, along with a clear maintenance schedule to keep your device running at its best.
Why Maintenance Matters
Portable oxygen concentrators work by drawing in air, filtering it, and delivering concentrated oxygen. Over time, dust, moisture, and general use can impact performance if not properly managed.
By following a consistent maintenance routine, you can:
- Maintain optimal oxygen output
- Reduce the risk of alerts or faults
- Extend the life of your device
- Ensure safe and reliable daily use
Recommended Maintenance Schedule
A simple routine can make all the difference:
- Weekly: Clean the pre-filter
- Monthly: Replace the filter cotton (if required)
- Every 3 months: Maintain unused batteries
- Every 12–18 months:Arrange a sieve bed service (via authorised provider)
Pre-Filter Cleaning (Weekly)
The pre-filter cover protects the internal system from larger dust particles and debris.
We recommends cleaning this on a weekly basis using mild detergent and water
How to Clean the Pre-Filter
- Remove the pre-filter cover from the device
- Wash it gently using mild liquid detergent and warm water
- Rinse thoroughly to remove any residue
- Allow it to completely dry before reinstalling
Why This Is Important
Keeping the pre-filter clean:
- Maintains proper airflow
- Prevents internal contamination
- Supports consistent oxygen delivery
⚠️ Important: Never reinstall the filter while it’s still damp, as moisture can damage internal components.
Filter Cotton Replacement (Monthly)
The filter cotton acts as the first line of defence, capturing dust and particles before they enter the device.
It’s recommended to replace the filter cotton approximately once a month, depending on usage and environmental conditions.
How to Replace the Filter Cotton
- Remove the pre-filter cover by hand
- Take out the existing filter cotton
- Insert a new, clean filter cotton
- Reattach the pre-filter cover securely
Why This Is Important
A clogged or dirty filter can:
- Restrict airflow
- Reduce oxygen efficiency
- Increase strain on internal components
If you’re in a cleaner indoor environment, you may not need to replace it as frequently, but regular checks are key.
Battery Care & Storage
Your battery is essential for maintaining mobility and independence. Proper care ensures it performs when you need it most.
If you’re not using your device for an extended period, our advice is removing the battery and maintaining it every 3 months.
How to Maintain Your Battery
- Charge the battery to 100%
- Use or discharge it down to approximately 60–80%
- Store it in a cool, dry place
Why This Is Important
Proper battery maintenance:
- Preserves battery lifespan
- Prevents capacity loss
- Ensures reliable performance when reused
If storing your device long-term, always remove the battery to avoid unnecessary wear.
General Safety & Usage Tips
Safe operation is just as important as maintenance. Here's several key precautions to follow during everyday use:
Key Safety Reminders
- Always read and understand the user manual before use
- Do not use the device near open flames or while smoking
- Avoid using the device in rain or exposing it to water
- Never submerge the device or accessories
- Do not block air intake or exhaust vents
- Only use approved Kingon parts and accessories
- Ensure the cannula is not kinked or restricted
Why This Matters
These precautions help:
- Prevent damage to your device
- Reduce safety risks
- Ensure uninterrupted oxygen delivery
Additional Maintenance to Keep in Mind
Sieve Bed Replacement (Every 12 - 18 Months)
Inside your portable oxygen concentrator is a component called the sieve bed. This is what actually separates oxygen from the ambient air using a specialised material called zeolite.
What Does the Sieve Bed Do?
- Filters nitrogen out of the air
- Allows concentrated oxygen to be delivered to you
- Enables the device to produce medical-grade oxygen
Why It Needs Replacing
Over time, the internal sieve material naturally degrades (typically 12 - 18 months), losing its ability to filter nitrogen from ambient air. Due to:
- Continuous air compression cycles
- Exposure to moisture and contaminants
- General wear from regular use
As it degrades, oxygen purity can decline, even if the device still appears to be working normally.
What You Should Do
Sieve bed replacement is not a user-serviceable task. You’ll need to work with an authorised service agent to:
- Test oxygen purity levels
- Replace internal components if required
- Ensure your device remains compliant and safe
Sieve Bed Replacement Costs
The oxygen filter sieve inside your portable oxygen concentrator typically lasts between 12 - 18 months, depending on how frequently the device is used. As part of ongoing maintenance, replacing the sieve bed is a standard service to ensure your device continues delivering the correct oxygen concentration. Oxygen filter sieve replacements start from $245, with a service fee from $135 + GST.
Final Thoughts: Keep Your Device Performing at Its Best
Maintaining your Kingon P2 Portable Oxygen Concentrator (P2-E, P2-E6, or P2-E7) doesn’t need to be complicated. With a simple routine and a bit of consistency, you can ensure reliable performance for years to come.
Whether you’re already using your device or still considering your purchase, knowing how easy it is to care for can give you added confidence in your decision.
