iSpring F10KU RO Replacement Filters Set Reviews

The F10KU is one of iSpring’s most comprehensive replacement filter packs in the market. The set is meant for 7-stage RO systems and it comes with 10 filter pieces that include both the alkaline remineralization filter and UV light sterilizer filter.

Like the iSpring FK9 above, this F10KU set features 6 prefilters comprising of two PP sediment filters, two granular carbon filters, and two carbon block filters. So you are also assured of a year supply of replacement prefilters for your RO system.

The pack as well features a 5th stage activated carbon filter for the post-filtration of the RO water as it leaves the RO storage tank.

For the 6th stage of the RO system, the set comes with two alkaline remineralization filters which are equally made of red mineral stones and calcite media as that of the FK9 set.

These two alkaline filters will make sure you continue to get RO water that has the essential healthy minerals and a much more balanced pH level for a whole year. Each of the filters lasts up to 6 months, thereby you will only need a replacement after a year.

The final filter which makes this F10KU highly attractive for those looking for that extra level of protection is the UV disinfection sterilizer filter. This is meant for the 7th stage in the RO system as the final line of defense before delivering the filtered water to the faucet.

The filter uses a powerful 11W Philips double-ended UVC lamp that emits strong UV lights which penetrate the water molecules to kill up to 99% of all remaining harmful microorganisms that the other filters could not remove.

It’s a highly effective UV light filter that removes all bacteria, viruses, protozoan cysts and other different microorganisms that are likely to linger behind and grow in the RO system or tubings over time.

The 10 pieces of filters measure 10” X 2.5” hence if you have a standard 7-stage ALK UV RO system with standard 10” housings, you will face no challenges incorporating them into your system.

The pack is ideal for the iSpring RCC7AK-UV or the RCC1UP-AK models. It can as well fit most standard 7-stage RO systems from other different brands.

Can this be added to an already existing iSpring 5 stage system?

Yes, you can, but you would have to get the UV light housing, control module, flow switch assembly. The alkaline filter would require the fittings to add it in, too.

Why the RO membrane stage 4 is not included in this package?

The RO membrane for stage 4 is not included in a 1-year kit as it normally lasts 2-3 years.
