& Replacement

When to Replace

  • Replace the molecular sieve every 12 monthsof use, depending on daily usage.
  • Replace sooner if you notice reduced oxygen output, longer warm-up times, or unusual noise from the unit.
  • Replace immediately if the unit displays a low-purity alert (if applicable) or if performance noticeably declines even after replacing the filter.

Maintenance Tips for Longer Life

Keep it dry: Avoid using the unit in humid environments, as moisture can shorten the molecular sieve's lifespan.

Keep the machine running:
We recommend using your SJ-OX1C regularly rather than leaving it idle for long periods. Extended inactivity can allow the molecular sieve to absorb moisture from the air, gradually affecting oxygen output. Regular use helps slow this process and keeps your unit performing at its best.

Pair with regular filter changes: A clean filter reduces dust and particles reaching the molecular sieve, helping it last longer.

Store spares properly: Keep replacement molecular sieves in a cool, dry place until ready to use.

Use genuine parts only: Non-genuine or incompatible molecular sieves may cause uneven wear or reduce overall device performance.

Frequently Asked

Questions

We recommend replacing the molecular sieve approximately every 1 year, though the actual lifespan may vary depending on local air humidity and how frequently the unit is used.

Common signs include reduced oxygen output, longer warm-up times, or the unit running hotter than usual. If you notice any of these, it may be time for a replacement.

Yes — humid environments can accelerate the aging of the molecular sieve. We recommend keeping the unit in a dry environment whenever possible to help extend its lifespan.

No. The filter is the outer layer that catches dust and debris before air enters the unit. The molecular sieve is the internal core component responsible for separating and concentrating oxygen.

Not at all. Replacing the molecular sieve is simple — no professional technician or tools are needed. You can easily do it yourself.

No. The SJ-OX1C supports user self-replacement of the molecular sieve, and doing so does not void your warranty. Simply follow the provided diagram to complete the replacement on your own.

The molecular sieve is a consumable component, and its lifespan naturally depends on factors like air humidity and how much the unit is used over time — so it isn't covered under the standard 1-year warranty. Every unit goes through rigorous testing before it leaves our facility, so you can trust that both the concentrator and the molecular sieve are fully functional and ready to go from the moment it arrives.
