Bhai, pehli baat toh tumko ye janna h ki filter ki condition kya h, usko kis cheez ki requirement h. Agar GKK ka sensor on h toh sirf GKK kit replace karo. Aur service cost koi membership ki tarah nhi hota Bhai Jo yearly ya monthly lena pade. Wo bas every service pe charge lete h. Aur area k upar v depend karta h. Mere area se service centre 100 km dur h toh yaha service cost thoda jyada h. Wese tum ko ek baar customer service se baat kar lena chahiye. Waha pe sara information provide karte h.
