About this item
- The RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7.0 or below. Alkaline filter produces pH 8-9 alkaline water with restored minerals such as natural calcium and magnesium.
- The Alkaline filter can be added to any under-sink water filter or RO system. 3 filters included.
- Raises pH level to 8-9
- Updated FA15 alkaline filters are built with a secure push-fit quick connection, which allows faster filter replacement. If you have trouble installing the filters, please refer to the user manual or contact us

Purchased an ispring RCC7 to remove the flouride and heavy metals from my city water. It definitely made a difference in the taste of the water. I never have tested the PPM of any contents. The water came out a bit acidic and bitter. I decided to add these alkaline filters. I was surprised by how delicious the water became. It tipped the PH back to neutral and added a full, rich flavor to the water. The cost for filtration is very reasonable. I'm not sure what separates iSpring from the other systems available but I have appreciated their product quality, packaging, and customer support.

Incoming ph is 6 before the alkaline filter and 7.5 after. So I would have to say the filter is doing its job.

The water really tastes good and I would say the taste is comparable to bottled water or better.
