Camry :: 2004 - Charcoal Canister Malfunction

I have a 2004 Camry that has had ongoing issues with the Charcoal Canister over the past 3 years. The first time we came across this issue the car threw codes that indicated the Charcoal Canister had to be replaced. Our mechanic said it had to be done and there were no after market parts for this canister. We paid the $800 for parts and labour and had it replaced. Then 13 months later the car began throwing codes again. I had the car looked at again I was told the Canister would need to be replaced... They felt it was likely caused from the intake filter housing cracking. Each time our car does this the codes can be cleared for a bit but the car takes forever to fill and slowly over time you can no longer fill the car as there is so much pressure. This time I bought a used part and replaced the canister. This has happened again..

So we have now replaced this filter 3 times in three years. Can I ask how this canister continues to get gummed up? We live on dusty roads in the country but none of my other Toyota's have had any issues with this. How these canisters are getting gummed up? Is there any way for me to change this Canister myself if I buy them used? I saw in a video on this forum where the user shows putting the car up on a hoist and lowering the exhaust to get to the canister. Do you have to have a hoist? I am wondering if I can achieve this with the car on a blocks? My original mechanic said the rear suspension needs to be taken apart to access the canister? Can I ask where the dust is being drawn from to clock this filter to begin with? I have also been told you can try blowing out the lines? How to attempt this?
