7-Stage UnderSink Water Purifier Kenya – RO + UV + UF

Get purified drinking and cooking water directly from your kitchen tap with this 7-stage under sink water purifier. The system combines Reverse Osmosis (RO), Ultraviolet (UV) treatment and Ultrafiltration (UF) in one compact unit.

The purifier fits beneath the kitchen counter. Therefore, it keeps the main filtration equipment out of sight while providing treated water through a dedicated drinking-water tap.

Why Choose an UnderSink Water Purifier in Kenya?

An under sink water purifier provides a dedicated source of treated water at the kitchen sink. Instead of filtering water for the entire house, it focuses on water used for drinking, cooking and food preparation.

The system sits inside the kitchen cabinet. As a result, it keeps the countertop clear while giving the household convenient access to purified water.

For Kenyan homes, an under-sink RO system can provide an additional treatment option when the drinking-water source has concerns such as unpleasant taste, high dissolved solids or other water-quality issues.

For a broader explanation of household treatment methods, see the guide to water purification systems in Kenya.

7-Stage RO + UV + UF Water Purification

This purifier combines several treatment technologies in one domestic drinking-water system.

Reverse Osmosis (RO) uses a semi-permeable membrane to reduce many dissolved substances from water. You can learn more about the process in this guide to how reverse osmosis purifies water.

Ultraviolet (UV) treatment adds another treatment stage for microorganisms.

Ultrafiltration (UF) provides membrane filtration as part of the overall purification process.

Together, these technologies provide a multi-stage point-of-use purification system for drinking and cooking water.

However, purification performance depends on the incoming water quality, operating conditions, maintenance and the contaminants present.

Is This a Borehole Water Purifier?

Yes. An under-sink RO purifier can treat drinking water from a suitable borehole source. However, the correct setup depends on the results of a water test.  For instance, very high sediment levels can increase the load on pre-filters. Similarly, high iron, manganese or hardness may require additional pre-treatment before water enters the RO system.

Therefore, households using borehole water should test the water before selecting a final treatment configuration.

It is also important to distinguish between a point-of-use borehole water purifier and a whole-house borehole treatment system. This under-sink system focuses on drinking and cooking water at the kitchen rather than treating every outlet in the property.

UnderSink Water Purifier Price in Kenya

The price of an under sink water purifier in Kenya varies according to its filtration technology, capacity, membrane, storage, number of stages and additional treatment features.

This 7-stage RO + UV + UF system is available for KSh 30,000.

However, price should not be the only consideration when comparing domestic water purifiers. Buyers should also check:

• RO membrane specification
• Filtration stages
• Storage capacity
• Purification capacity
• UV treatment
• Booster pump configuration
• Replacement filter availability
• Filter replacement costs
• Installation requirements
• Warranty and after-sales support

A lower purchase price does not always mean lower ownership costs. Therefore, compare the complete system and its maintenance requirements before buying.

Product Specifications

Who Is This Water Purifier Suitable For?

This system suits households and other users who want dedicated purified water at the kitchen.

It can work well for:

• Homes that want purified drinking and cooking water
• Apartments where kitchen space matters
• Tenants looking for a compact point-of-use system
• Offices that need purified drinking water
• Borehole-water users, after assessing the source water
• Municipal-water users who want additional point-of-use treatment

For larger water-treatment requirements, Pureflex also offers domestic and commercial water purification services.

Maintenance of an Under Sink RO Water Purifier

Like other domestic RO systems, this purifier needs regular maintenance.

The required replacement interval depends on several factors, including:

• Incoming water quality
• Daily water consumption
• Sediment levels
• TDS and dissolved mineral levels
• Operating conditions
• Filter type

For example, water with high sediment levels may require more frequent pre-filter replacement.

Pureflex also supplies RO replacement filters and membranes. This makes it easier to maintain compatible RO systems over time.

What Water Should Be Tested Before Installation?

For borehole and other private water sources, useful laboratory parameters may include:

• pH
• TDS
• Electrical conductivity
• Hardness
• Fluoride
• Nitrates
• Iron
• Manganese
• Chloride
• Sulphates
• Microbiological parameters

The right test panel depends on the water source and its intended use.

For example, testing becomes especially useful when water has a salty taste, produces scale, develops an unusual colour or has an unusual odour.

Frequently Asked Questions

How much is an under sink water purifier in Kenya?

Prices vary according to filtration technology, capacity and configuration. This 7-stage RO + UV + UF system is available for KSh 30,000.

Which water purifier is suitable for borehole water?

The right purifier depends on the borehole water analysis. Reverse osmosis can help reduce dissolved substances in drinking water. However, some borehole sources may need pre-treatment before the water reaches a domestic RO system.

Can an under sink purifier treat salty water?

RO systems can reduce dissolved salts. However, suitability depends on the salinity and other characteristics of the incoming water. Very high-salinity water may require additional treatment before entering a domestic RO system.

Is an under sink water purifier suitable for apartments?

Yes. An under-sink system provides point-of-use treatment for drinking and cooking water while keeping the main equipment beneath the kitchen counter.

How much water can the purifier produce?

This model has a stated purification capacity of 18 litres per hour. If it operated continuously at that rate, the theoretical output would reach approximately 400 litres per day.

Does the purifier have UV treatment?

Yes. UV treatment forms part of the purifier’s 7-stage RO + UV + UF configuration.

Does it have a storage tank?

Yes. The purifier has a 12-litre storage capacity.

Can it be installed under a kitchen sink?

Yes. The system uses an under-counter installation configuration.

Does a TDS meter test for fluoride?

No. A TDS meter measures conductivity related to dissolved substances. It cannot determine the fluoride concentration specifically. A suitable fluoride test or laboratory analysis is required for that.

How often should RO filters be replaced?

There is no single replacement interval for every household. Filter life depends on incoming water quality and usage. Regular inspection and servicing can help determine when individual cartridges need replacement.
