I've only had my current device less than a month, so this response is largely based on my previous S9 Autoset.
I found that using a small headed soft bristle toothbrush effective at getting into those areas where my water tub seemed to build up crud missed during my typical daily washing routine. Looking at my new PR System One water tub, I can see that it has many more areas that might potentially need attention. That said, i replaced my first S9 water tub at about 9 months due to a breakage (my fault) of the 2 smaller plastic nub things on one side of the lid that the clamping part needs to lock onto. I next replaced the tub around 12 months later when I got my new device and was packing away the Resmed device as a backup (since passed on to an in-law looking to get an S9 Autoset).
Machine filters are a relatively low cost item and were replaced monthly. I replaced the ClimateLine at around 12 months. The old one seemed fine but i figured 12 months was probably EOL for this type of component.
Mask parts were replaced as needed. Up until recently I used the Swift FX. I found that pillows lasted about 2 months, headgear about 4 months, and I changed the mask short tube at the same time as my devices ClimateLine tubing based on the same reasoning.
Im in Australia and everything apart from the APAP devices themselves are purchased out of pocket, although safety-net arrangements seem to exist for those in need. My own private insurance covers only $500 towards the purchase of an APAP device provided certain criteria are met, e.g. having undertaken sleep lab testing within the 18 months prior to purchase. On the other hand, my insurance covers 100% of the cost of things like sleep lab testing.
I buy the majority of my CPAP supplies online from the US where practically everything is at least half of the price being charged here. To minimise shipping costs I tend to make annual bulk purchases at only 1 or 2 suppliers. I'll typically get a heated hose, water tub, mask short tube, and at least enough device filters, mask headgear and cushions/pillows to last me through the next year. Due to a change in mask type and APAP device offering alternative hose routing possibilities, this year I've added the purchase of some 'comfort' type items to my purchase list which has meant sourcing from a couple of additional suppliers - Whether this will impact my purchasing strategy next year is still unknown.

My insurance company replaces CPAP supplies as follows:
1 month: 2 disposable filters, 2 nasal cushions (or nasal pillows for those that use them) or 1 FFM cushion
3 months: climate line tubing, frame with cushion
6 months: water chamber, chin strap, head gear
Most insurance companies follow the medicare guidelines which I have listed above (this is for the US of course).
