How to handle allergies from lint in CPAP tubing?

clean it

I wash my tubing and mask through with very hot water after use and have mini blower to thoroughly dry them.
Worth the few minutes especially if you are immunocompromised.

I never have lint, or anything I can see, that builds up enough for me to see over time, in my 'Climate Line' heatable tube. Also, I only clean my tube about four times each year. It doesn't seem to be necessary, and I have no symptoms for want of doing it much more frequently.

So, 'we' have a problem if it's lint, but also if anything....at all...is building up inside your tube. You have no filter, or it's dislodged, or your bedroom/CPAP environment is badly polluted with airborne particulate matter. If the latter, your filter should show it and need replacing every week or so. I replace mine once a quarter.....honestly! I have been thinking of doing it, so it must be due. 😀

Seriously, there's something amiss for you. You can remove the tube and fill it with a disinfectant and let it sit for an hour, then rinse three or four times, hang it, and let it dry for most of the day. Or, purchase a new tube.

For a disinfectant, I use sodium or potassium metabisulphite. It's a white powder available very cheaply at U-Brew It beer and wine outlets where patrons make their own batches of wine and beer. In solution, it kills bacteria and molds, not sure about spores. Maybe $5 for a sachet that should last you about a year. You mix a heaping tsp of the powder in four cups/one liter of tap water, shake and mix, and then fill the tube with the solution. Let that sit for a few minutes, and then either discard the solution (safe down the drain) or rebottle it and use it again...as I do (remember, my tube is apparently clean, or clear, so reusing the solution is not unwise. In your case, it would be best to flush it down the drain). Rinse well!

With that done, you need to figure out why you have so much ingress/throughput of particulates, IF that's what it really is, and not mold, into your tube.

@seniormed - are you meaning a mini blow dryer to dry your tube? You just aim the airflow down the tube?

Yes battery powered on Amazon.
Very strong hi speed with different
size attachments 40$ range.

I have found my solution to keeping the tubing dry and therefore clear of anything by putting clear wall hooks by my bed. In the morning I detach all tubing from the machine. Then I separate the two tubes and hand each on the hooks. The long one loops over the hook and the other I hang from the face mask straps. Then I empty the excess water from the tub and leave it open to air dry during the day. I have been doing this for 3 years or more and it works great!

On Amazon - I searched for "CPAP Starter Kit". The CPAP Tubing Brush works very well.

This is the one I have. I see there are now options to add blower unit, kits w/o wash basin, and other options.
