Nanofiltration membranes are very similar to RO membranes, but they have larger pores. Its larger pores result in a lower reduction in TDS, so it is considered an excellent choice for low TDS feed water (<1300). Regular RO membranes, on the other hand, remove up to 98% of TDS from water. In areas with low TDS, RO can actually demineralize water to as low as 20 TDS. Such demineralised water is not fit for drinking purposes as it lacks several essential minerals that our body needs. According to WHO, drinking demineralized water over a long duration can cause several health issues like - Cardiovascular diseases, pregnancy disorders, certain kinds of cancers and weak bones. NF membranes can be chosen as per your input TDS with TDS reduction ranging from 20% to 80%. They also waste less water and consume less energy. ___________________________________________________________________________ About Peore: Peore is India's first tech driven no-frills water purifier brand which provides personalised home purification solutions suited to the needs of its customers. Peore has been founded by a bunch of IIT Delhi grads who are on a mission to provide everyone access to quality drinking water (minus the gimmicks). Our founders realized that the Indian water purifier market, despite being such a large and old industry, is devoid of any innovation and follows very unscientific practices. For example, a large chunk of urban population still continue to use RO purification at low TDS and drink demineralised water with TDS as low as 20. Supply water quality varies for every household and we believe that there is no one silver bullet which can solve purification needs for every household. Our goal is to provide the right purification system to our consumers through generating awareness, strong on-ground presence and innovations like our proprietary Nano-RO purification
