Air purifier has become an essential appliance in every home and especially during the hazy season, it sells like a hot cake. I bought this back in 4 years ago when the haze problem became intolerable in Malaysia. This is a basic air filter with HEPA filtration with Plasmacluster Ion feature from Sharp. I took this opportunity to tear it down when it requires thorough cleaning since the day I bought it. Let's get our curious mind going and look what's inside.
