KNL NF60 ro Service kit NF Membrane 100 GPD Sediment, Activated Carbon Block (pre Carbon), Activated Post Carbon, PP Spun Filter & FR 450 Filter/Cartridge/Candle Set for Domestic Water purifiers

The input water TDS 300-350 and after installing the whole system, the current TDS ia around 140-150 TDS.On initially the TDS level is around 190, but I recommend all of you to wait for 10 mins or more the TDS level will come down to it's original level. The product quality is worth it.

Very very good product, but price is little bit high.

Bought a replacement set in March end. Got it fit and assembled in April after thorough cleaning by the original technician who assembled it the first time. Cut to August, water had started to form cloudy particles. We called the original technician who confirmed after inspection that the membrane has a problem and needs to be replaced. (Input TDS- 650-700; Output TDS- 445)I called KNL. They said it could be either blockage in flow restrictor or there is a pressure pump in overhead tank that is mostly in high rise buildings. None of which is the case with us. The FR is working fine and we don't have a pressure pump to direct the flow as we live in a 2 storey house. And thus, they who refused to replace it of their own accord citing no warranty on out of box filters (even their very own same set of filters as in the original machine) also claiming it's the standard industry practice and almost giving a huge surprise and shock that how could it even happen to their dear product. (we are 3rd such case as per him!!!). I then called a local supplier of RO membranes who said that they provide an year long warranty on out of box parts and membranes. Thereby, totally refuting on KNL's claim of "industry practice". This already proves the lack of knowledge and his intention to not acknowledge any possible and reasonable complain on account of quality control issues.The membrane is faulty. It did not last even close to its service life of 18 months/15000L. They have been in use for tad above 4 months. The original machine had a 6 month warranty of inline filters which the manufacturer already led you to believe as some path breaking innovation in after sales service that no other manufacturer provides. BTW, another claimed feature, a transparent tank is also a disguise for and compensating for the poor structure of the purifier box leaving gaps for tiny insects and bugs to infiltrate in the tank from all places which doesn't happen with other companies' purifier installed by our neighbours.Cut to now, the manufacturer is chickening out and not taking any responsibility to replace the membrane on his own. I don't know if I have a case against them in the consume courts that offers me speedy redressal. I'll have that checked. But, it's a cautionary tale for anyone looking to buy the same that it's essentially a coin toss and the manufacturer will put all stops but admit it's fault and agree to stand behind the product's serviceable life. Because if the machine had a warranty of 6 months for inline filters if it gets clogged then so should the same replacement filters which were installed by the same guy. Otherwise, all you ever bought was 6 months worth supply of clean water and then a being offered a chance to be able to get clean water supply for its subsequent life for which you have to pay ofcourse but for which we won't take any responsibility even if it's same thing because we can under the terms of service. But we do offer you one thing for the rest of the life. One poorly designed electric PLASTIC DABBA!!! Hope it's enough to keep you interested in our products.You decide. If this is worth the coin toss for your time, your money and, your health.

Many of us are unaware about NF membranes.. due to the name and fame of RO membrane.. As i was also searching for service kit of my ro machine.. I came here by the name of BARC... I tried this as experiment.. and is successful. My municipal water supply has the tds of 450 to 500.. so I tried NF 60 and now after NF60 the tds is 158 to 190 which is quite ideal to drink.. highly recommend for tds upto 600 tds and stop harming your family by ro membranes.. and also it saves water bcz out water flow is higher than ro membranes. Everything else is fine but its price should be low so that it encourages us and people use more and more NF membranes.

I replaced my aqua guard reviva filter set with this set. Easy to do it as DIY. Make sure you use the new elbows provided in kit to join pipes as using it with existing elbows cause leakage.Also NF filer does not come with outer jacket box which needs to be ordered separately as it’s required to fit in Reviva model.After install : Input TDS is 500 and Output TDS is 140

Nice product, using it from last 3 years which is satisfying. TDS as expected

The popularity of RO has shadowed NF membrane utility, and KNL has been BARC Certified, I came to know about it on a youtube video.Suited for Kent Grand plus whose kit change was priced at 6000 rsWhereas this with Pre-filter and prefilter casing cost about 3100Remember to use a Teflon tape to fit all threaded joints, especially that of the RO housing, it creates a high pressure inside resulting in leakageWish you all luck for your DIY

My tap water tds was 487 ppm. After install knl 60 nf membrane my tap water tds is now 102 tds. How is it possible? Company claim that after install it tds reduce upto 60%. Then, how does it become 102?
