AirSense 10 Filter - When to Change & Loose Fibers - Phil7 - 10-13-2021

I have a 1 month old AirSense 10.  This is my first time on a ResMed machine after around 12 years on CPAP oddly.

1.  One month of use looks like about maybe it's 1/3 of the way through the filters useful life as a guess.   I'm just guessing though.

2.  I obviously didn't know this until looking at the pictures, but the 1 month old filter has a whole lot more random fibers sticking out on the edges.  Can those filter fibers break free and directly enter the air path?   As a general guess, I'd assume most any tiny debris in the air path would get stuck in the water tank or mouth before getting to lungs.  But, I have no idea.

Thanks

Filter lifespan is a function of air quality in the room, more than simply time. If there is a lot of fine airborne particulates in your bedroom/house, that would shorten the life of the filter.

An open fire or some sort of solid fuel heater anywhere in the house will dramatically degrade air quality in this way. Having windows open for long periods might do it too, if there is significant particulate 'pollution' outside.

I get around two - three months from each filter when at home (I use the fine type) but sometimes less when traveling and staying in 'dirtier' accommodation. That's based on 8hrs use per night.

Particulates in the air path would not get caught in the water since the air passes over and not through the water. I suspect most would would be caught by the cilia in the bronchial tube. That's how are bodies handle fine particulates that we breath throughout the day.

Thanks.  I'm thinking too much.  I haven't ordered a stock of supplies yet for the new machine.   With the supply chain issues, and warnings to order early for Christmas, I'm working on buying up about a years worth of supplies, just to be safe.    Also, I live in TX and (winter storm) just went through almost 3 days of no power.   I didn't have a good UPS and generator to charge a UPS in the day.   I don't want to be caught w/ my pants down again.

With everything cleaned, I found floaters in the tank of a Dreamstation, after removing the cancer foam via that coat hanger method.   I've seen where everything cleaned and dried can end up showing some kind if very tiny debris in the water tank.  That was on my mind anyway.   I assumed pulling the foam out with a coat hanger caused tiny plastic scrapings.  Plastic can adhere hard to other plastic while wet at times.   Whatever happen, I've seen some kind of particles float in a tank that most likely originated before where the air went through motor chamber. I kept the air filter on the filter port at all times while disassembling and re-assembling the machine also. Just something odd I noticed under the weird circumstances of taking a machine apart.

Interesting question.   I just bought a set of hypo-allergenic filters for my new AirSense 10 today.  They seem to be much less fluffy than the standard filters.    That being said, even my few days old standard filter doesn't have nearly as many fibres visible around the edges as the pictures you posted.

Here's a picture of one of the hypo-allergenic filters.

For myself, if I saw a discolored filter such as that, I'd change it and be done. The filter is a low cost item protecting the more expensive PAP. The filter sacrifices itself to do its intended function. As is, I'd changed my filter monthly regardless of looks.


RE: AirSense 10 Filter - When to Change & Loose Fibers - Phil7 - 10-14-2021

Looks like a pack from a CPAP supplier ends up being $0.60 per filter for the hypoallergenic name brand ones.  That's  $2.40 vs $7.20 per year.      Interesting.  $5 more a year to change the filter every month vs every three months.  

OK, you sold me. I'm cheap but not this kind of cheap.   $5 extra a year to just change your filter every month and never risk the air flow being restricted at all.  Sounds  like a good deal considering the "no thinking" aspect.
