It is time to change my aircon filter. Last change was at 30,000km mileage. Now, it's already 50,000km. Suppose to change every 15,000km but I didn't.

Saw this product at NTUC supermarket. Bought it at $19.90 just to try it on my car. Anyway, just need to implement this twice per year only. The process is simple,

1. Start the car
2. Turn on the aircon and circulate mode ON.
3. Pull the front passenger seat forward.
4. Put the canister on a cloth and press the button to activate the particles.
5. Close all doors and windows and let it run for approximately 10minutes.
6. Once done, wipe the interior dry
7. Job done!

Conclusion, it gives a slight citrus smell and seems slight improvement on the air quality. Most importantly, have to keep the car interior clean.
