Kind Water Systems PRO-RO-R EU (Replacement Filters, 1 Year Supply)

How often should I replace each filter in this kit?

The carbon filter for stages 1-4 requires annual replacement, whilst the two PRO-RO-56R cartridges for stages 5-6 need changing every six months. This means you'll use both stage 5-6 filters within the year, making this a complete annual maintenance kit. Regular replacement ensures optimal filtration performance and maintains water quality standards.

What is the maximum TDS level these filters can handle?

These filters support water with Total Dissolved Solids levels up to 2000 ppm. This capacity covers most UK water conditions, including areas with hard water or elevated mineral content. The system maintains effective filtration performance even with high TDS input water, ensuring consistent output quality regardless of source water variations.

Do these filters actually add minerals back to the water?

Yes, the PRO-RO-56R cartridges in stages 5-6 actively remineralise the water by adding back beneficial minerals like calcium and magnesium. This process occurs after the initial reverse osmosis purification, ensuring you receive clean water with essential minerals restored. The remineralisation improves both taste and nutritional value compared to standard RO systems.

Are these filters compatible with other reverse osmosis systems?

These filters are specifically designed for the Kind Water 6-Stage Reverse Osmosis System model PRO-RO-R EU. They feature proprietary quick-connect fittings and dimensions that match this particular system. Using them with other brands or models may result in improper fit, leaks, or reduced filtration performance.

How difficult is it to change these filters myself?

Filter replacement is straightforward thanks to the quick-connect fitting system and hygienically sealed cartridges. The process typically takes just a few minutes per filter and requires no tools or technical expertise. The sealed design prevents contamination during replacement and the quick-connect fittings eliminate the need for complex plumbing work.

What contaminants do these filters remove from water?

The multi-stage system removes chlorine, sediment, organic compounds and various dissolved solids through the carbon filtration stages. The reverse osmosis process eliminates bacteria, viruses, heavy metals and microscopic contaminants. The final stages polish the water whilst adding back beneficial minerals, creating clean, safe and naturally balanced drinking water.

Will these filters fit under my kitchen sink?

These are replacement filters for an under-sink installation system, so they're designed to fit within the existing Kind Water system housing. The filters themselves are compact and won't require additional space beyond what your current system occupies. The installation type is specifically designed for under-sink mounting to save counter space.

How do I know when it's time to replace each filter?

Follow the recommended replacement schedule: carbon filters annually and PRO-RO-56R cartridges every six months. You may also notice changes in water taste, flow rate reduction, or TDS level increases as indicators for replacement. Some users mark calendar dates or set reminders to ensure timely filter changes for optimal system performance.
