Hlo before 2years we brought aqua grand plus reverse osmosis water purifier and
It is 12 liters capacity
It consumes less power
And every 6 months we need to change inner batching chamber
Also we are servicing every 6 months once
Iike this we are careing
But even though it leaking water drop by drop and also it is not tasty when we stop servicing then water will not filter
Also we need to change water balls they gave 3years warranty but within 1 year it get repaired
We inform to service man and he repair the purifier
We can’t found interior waste left over from water
This is our experience with aqua grand plus reverse osmosis water purifier
thanks for reading
