I was reading suppose to change everytime when service the AC.  🤔

No la  . Last time where got such thing as service ac. Change the ac filter nia. What else can do?

Now got the suction machine to change oil. That why they recommend ac servicing.  But still no need to touch drier.

normally ws change the receiver drier when the fluid or oil in the ac system is corrupted. Or so call dirty ( the compressor internal break or damage. Grind out the metal or aluminium powder.  The drier is like a filter. So Need to replace.

Recovery of the refrigerant is ok. Once dismantle the AC system for repair, moisture will be introduce.

100% right. Use machine just to service is a con job. 
all suckered into buying and then have to sucker consumers to pay. 
the original purpose of the machine are

1.to recover the refrigerant so that it is not release to atmosphere.

2. Make sure the correct amount of refrigerant and oil is added.
