BNQS RO Membrane 80 GPD Works Upto 2000 TDS for All Types of Water purifiers

nice quality

Initially when I installled water TDS was around 100 ,but after a 1 or 2 days ,water is 10 TDS .my actual water TDS is around 300. Overall good will have to see how long it'll last.Update on 15aug2020 - water tds is stable at 10 tds

Membrane gives good performance at the beginning for 1 Month. (At Tap water 350 TDS output It will deliver 40 to 45 TDS and water output in Liter will be 12 to 15 Liter per Hour. BUT !!!!!! but After One Month day by day water output will decrease and every month approx 2 liter water flow will reduce on per hour basis. it means you will get approx 10 liter in next 2nd Month, in 3rd month 8 liter, in 4th month 6 liter, in 5 month 4 liter, in 6th month 2 Liter and finally with in 6 to 7 month this Membrane will choke fully,HenceIt means the Life of Membrane is only Approx 6 Month, In price of five hundred the life for six months are ok But the flow is reducing day by day shows that the raw material used in this membrane is low quality.

I have used it. It worked only for 11 months. I am expecting it should work for 18 months. So I am giving 3 star.

I bought this RO membrane about nearly 2 months ago and here is my review. Many people think its unhygienic to use low priced membranes which is not true, because the filtered water coming out of membrane is devoid of chemicals even from plastic chemicals of tubings inline filters etc. prior to membrane input. I will give an idea of the quality of this membrane. My tap water tds is 208. My RO water using this wellon membrane tds was ONLY 12 (twelve) which showed a water rejection ratio of 94% which equals the standard of some branded membranes costing about 1600 rs approximately. Till today the membrane output water is still 12 as the tap water tds has not changed.This membrane will last very long, provided you use a new flow restrictor of 550ml. The lower the TDS of your water the better it is, because you get minerals from the food we eat and not from water. We used to drink water from rivers after rainy season and that water is from the rain. The rain water TDS i tested is only 2 to 5 range. Low tds water will never leach your body minerals which is a very wrong misconception from most people. The sweetness of your water comes only from calcium compounds from water. Some membranes filter more of calcium compounds than other sodium compounds. BUT this does not mean to say that your membrane is not giving sweet water.Your RO water should read TDS between 5 and 150 no matter what your tap water reads.For middle aged people, if water contains more salts then more water is absorbed into their body. When the water in the body is more and it cannot throw the excess water quickly, then there will be load on the heart and blood pressure will rise. So use water with less salts and stay healthy. Nowadays our rivers are getting more polluted with many unknown chemicals from factory wastes. So i expect every home should have an RO even if their tap water is sweet and looks clear. In my opinion Wellon brand , though its new to market, it surely is of standard quality.

Good product with lower price. But it gives a higher TDS in new condition. After using it 15 days it gives a output of 100 TDS.

Bought this twice in two years and both the times it served it purpose well.It reduced the TDS from 600 to 30 and lasted for more than an year. After 1.5 years I ordered this again and replaced.The TDS increased to 250 after approx 1.5 years (so I can say this is durable and good product) - Ideally we should change the RO Membrane once in an year for proper TDS.

The problem is only its work well for 1 month and after taste disappear.The flow is good but taste will disappear.Over all ok as we see price. Compare to market cost is awesome.
