you are right being upset about it because 2 of these stages filters need to be changed 4 times a year and the others at least 2 times a year. it can differ based on the water you get but generally...
Hi - Also Please check the technology of purifier. If this is RO technology it will waste `~ 70 % as reject adding to DEWA Monthly bill. I had this problem with RO filters so switched to Nanopositive filter technology with Zero water wastage.Now I have seen a reduction in Monthly DEWA bill.
