I brought aquaguard superb ro+ uv + uf 3 month ago because the water from our boring started becoming salty. I went to a shop where the shopkeeper highly recommended it to me. After only a month the water purifier started causing problems. We called maintenance guy and he fixed the problem. A few days later it again broke down and stopped working all together. I again called the maintenance guy and this time he took the purifier with him as he could not find the fault. He returned it after 5 days, installed the purifier but now there is a faint noise coming whenever the purifier works. We again complained but no action is taken till date. I am fed up of their customer service and would advice you against buying it.
