Now in White and blue gasket combination from 4th July 2022 onward. Nano Filtration TFC dry nf membrane 100 gpd by BARC (Bhabha Atomic Research Centre transferred technology). Its pore size is 0.001 micron and rejection rate is 40% to 50% and retains mineral TDS between 50% to 60% in drinking water naturally. Initially the membrane need to flush 20-30 minutes with FR 450 and then check the result. The result would be as per mentioned descriptions. The membrane is suitable for almost all kind of electric operated RO domestic water purifiers. For better result, use with 100 GPD booster pump, working pressure 80-90 PSI and 450 CC FR. In case of excessive tap water pressure (due to high rise building or pressure pump used in overhead tank) the Pressure Regulator valve is recommended to use else membrane may get damage early and the result may not be satisfactory. The membrane is suitable for soft water having TDS between 150 ppm to 350 ppm or max 400 ppm. The water born microbes/germs/virus size remains between 0.01 micron to 5 micron those are eliminated with 100% surety and being flushed through rejected water. The membrane also eliminates harmful chemicals, pesticides, herbicides, toxicity, bromide, fluoride, cyanide, arsenic etc and other impurities from water and flushes them through rejected water but UV & UF cannot. Life of this membrane is around 15000 liters or 18 months whichever is earlier. Medically recommended range of TDS in drinking water is 100 ppm to 300 ppm. Demineralized or low TDS in drinking water causes healthy problem in long run like slow digestive system, hair fall, obesity, bad cholesterol etc. The NF40 reduces pH very negligible up to 0.6 pH. TDS adjuster allows impurities back into drinking water. Use always right technology of membrane instead of using TDS adjuster/controller. Please note with more TDS water taste will be hard comparatively with RO water or demineralized water, bottle water etc.

Water wastage is more.. not value for money
We have a kent grand ro purifier. Before our water was mix of ground and municipal which has tds 500+. Recently raw water is only municipal with tds only 150. So decided not to use RO. Best alternatives are uf+uv for this tds. But again uv is radiation technology which only kills germs but not remove them. So instead of UF+UV purchased this NF membrane which is not upto expectations. Previously with RO tds reduction is 90% and water wastage is approximately 20 liters per 15ltr pure water. But in NF membrane raw water tds is 150 nd pure is 60.. reduction of 60% and wastage is approximately 30ltr for 15ltr pure. So its double nd more than RO membrane. According to description water wastage and tds reduction should be 40% but it is not in my case. Contacted the seller but he is showing theoretical proofs and asking me " aap technical baath samjiye". Funny if membrane is good it should have theoretical, technical and practical applications same but not. Water wastage is more.

Perfect membrane for low TDS water.
Input water tds of my machine was 400. But after replacing the ro membrane with this knl nf40 membrane, now the output water tds is 146 which is perfect and healthy. So guys dont use ro membrane if u have low tds water. Just change the ro membrane with this nf membrane and forget about tds controller,uf,mineral like garbages.

got healthy water finally
I purchased this in@1250. Price is competitive as CM purifiers(currently ITPL)are providing Permionics brand membrane @2500. taste of water is sweet n smooth after 15 ltr flushing. working perfect. future is of NF membranes.Do'nt fall pray to the TDS adjuster, or mineralizer cartridge scam. Adding chemical minerals to water is not healthy practise. NF membrane is perfect solution .

Good product. Nicely defined for which type of water supply it should be used.
Now having tds between 50-150 range. Now from this membrane I am having 68-72 tds (supply water tds is 120-140 tds. Previous membrane was of vontron model ULP1812-80 which is suitable for ground or high tds water above 600 tds but not for supply water. I used to have 4 to 14 tds which is quite not good for health and bones. I am really happy with product. Just want to see how long it gives its service. Best for supply water.

Nice product
This membrane is value for money because the TDS of normal water is reduces 50%.I recommend this membrane where to use if you want to your TDS Level becomes half.

Good product
TDS increased around 170 which is great. I replaced my RO memberane with NF40. My RO memberane was wasting lot of water and decreased TDS below 20 which was unsafe.

excellent product and service
excellent productafter good search found this companyit is better to use this filter to retain minerals in water we drinkro filter removes all minerals tds controller is not good optionmoreover prompt service for installationvery much satisfied with product and service
