High everyone, I finally managed to acquire an air purifier machine 10 days ago after a couple of aborted attempts via ebay and have been using it ever since. Cost me just $AUD66 which is cheap and cheerful. Its ugly but effective.
For anyone who suffers from constantly blocked nasal passages I can report that so far so good. I have used my nasal mask solely since getting it.
The machine supposedly has 9 filters including HEPA and ozone etc. Whilst I am a bit of a sceptic about how wonderful the whole air filter/purifier thing is I do believe it is working better than I even hoped it would and helping my apnea. I have run it daily for a few hours at least and when I go to bed I no longer get the nasal passages blocking up as I lie down. (seems to indicate I was getting blocked nasal passages due to allergens) I have gone 3 nights in a row without using a Sinex nasal spray and the last time that happened was when I was on holidays in US in January.
My apnea continues to be extraordinarily improved this year since the trip to America and with the improvement from the air purifier I can say I am one of the lucky ones. Having had apnea at the low end of the severe scale for reasons I cannot explain I am now in the low range. I use my machine every night and whilst my results almost suggests I am "cured" and not suffering sleep apnea I know I do if I do not use the machine (as we tested it) I snort and stop breathing and snore.
My wife is still a big fan of the airsense autoset 10 to be a big improvement on the Resmed autoset 9.
