I bought Pureit Marvella RO in 2018 and giving this review after an year of use. Pureit has very high maintainence cost. Salesperson will mention that maintainence is required after an year. Whereas red lights on RO will start appearing after 3-4 months of use. You are forced to replace GK1 and GK2 as the red-light starts appearing on the RO. Cost is very high, for example: GK1 will cost you 2500INR+ 350 service charges. I was buying KENT RO but the salesperson convinced me that Pureit has very less maintainence cost. After an year of use, I feel I made the wrong choice and to help others, I am giving this information.
May be salesperson have high margin on pureit products, that is why they try to convince customer to buy it. Please do a through analysis before buying.
