iSpring FA15 is a high-quality inline alkaline water filter and it comes in two versions, a new upgraded version, and an older version.
In this review, we look at the new iSpring FA15 version which comes with a few upgrades that make it much better than its older version and most other alkaline water filters in the market today.
The first thing that makes this upgraded iSpring FA15 model stand out is the set of media that it comes with. It’s a 3-lay mineralization filter cartridge made up of red mineral stone, calcite and corosex.
The purified RO water first goes through the mineral stone side (red), then moves through the calcite media side (white/clear) where it exits towards the RO faucet.
As the RO water passes through the filter, the three media restore back the lost minerals which include calcium, potassium, magnesium and sodium ions which in turn improve the pH level of the RO water.
The filter is capable of raising the pH level by 0.5 to 1.2 which makes it quite effective for use in areas where the source water has a very low pH level.
All the media and material used in making this iSpring FA15 filter are all-natural and FDA grade hence they are not only safe. They will leave no residues behind or further contaminate the water as the synthetic alkaline filters do.
The updated FA15 alkaline filter can work with any under-sink RO system. Unlike the older version, this one features a very secure push-fit quick connection for quick installation or replacement at the end of your RO system as the last stage.
You just need to screw the push-in connector on each end then attach a ¼” water tube on both sides. However, the flow direction arrow is not that well labeled like in the older FA15 alkaline filter but it can be installed in either direction.
The filter does not affect the normal flow rate of water and considering that it’s an inline filter, you won’t need to buy housing. It can last from 6 to 8 months depending on the pH level of your RO water.
