reducing dust wear of turbine

[cexer]

while watching a video about the resmed-10-successor,
the utuber came across the dust issue.

he said the standard air-filter just stops 75 % of 7 mµ dust
and some BMC.. (what he sais ?) stops 95 % of 2 mµ dust.
and then one can look at anti-bacterial, viral ?

but wouldn't there to much draw with such ?
can there be made an improvement to protect the device
or should it just be left as is ?

could an external air purifier help instead ?
could you recommend one
or even just a filter for putting into an air vent ?

Unless you have an excessive dust, pollen, or mold issue that affects you medically, most external room filters, other than the one in your HVAC system, are unnecessary.

As long as you change your CPAP filter on a reasonable schedule, depending on your environment, there should be no issue with dust in the turbine. My S10 was over 5 years old and there were no significant issues--and minimal dust when the motor was replaced.

Per the Medicare schedule, I receive six Hypoallergenic filters per three-month period and change them twice a month. I specifically requested hypoallergenic filters rather than the standard ones as they appear to have a tighter weave.

Per ResMed...
Standard air filter: Material: Polyester non-woven fiber. Efficiency: >75% for ∼7-micron dust.
Hypoallergenic air filter: Material: Acrylic and polypropylene fibers in a polypropylene carrier. Efficiency: >98% for ∼7 to 8 micron dust. Efficiency: >80% for ∼0.5 micron dust.
During Covid, I had considered cutting up an N-95 mask to use as a filter but was advised that it would make no difference and could actually increase the resistance to incoming airflow.
