When should the MAF sensor be cleaned?

[Flipo]

Engine air filter... Every 6mos
Cabin air filter... Every month

Note that my cars are GrabCars...change not clean...

Average 200kms per day

DIY the TB by using an old rug, tb cleaner and a toothbrush.
Change the air filter every year, I just vacuum mine and reuse it. Then change every other year.
Clean MAF sensor, maybe every year or two. It depends how often you drive the car or if you notice any change in fc and or idling.

Anong brand ng car po ito, at kung madaling kalasin yung TB?

Yung sa Ertiga kasi they charge 1.2k for TB cleaning, parang mahal?
