What is (RO) Reverse Osmosis?

Reverse Osmosis (RO) is a water purification method that pushes water through a very fine filter. This filter blocks dirt, chemicals, bacteria, and even dissolved salts. It's one of the few systems that can turn salty water and borehole water into clean, safe drinking water that tastes fresh and sweet.

Removes salts Removes bacteria Removes chemicals

99.9% Purification rate

Why reverse Osmosis

RO removes both visible impurities and invisible contaminants like salts, fluoride, chemicals, and bacteria. It is powerful enough to purify salty water, hard water, borehole water, municipal water — basically any type of water — and make it safe for drinking and cooking in Kenyan homes.

New Building? Here's Why You Should Test Your Water for Lead and Copper First

In newly constructed buildings, solder used to join copper pipes can leach lead into the first several litres of water after periods of stagnation. Flushing taps and using RO filtration protects against this risk. The Source: Pipe Joints and Fittings In Kenya, copper and CPVC piping are common in residential and commercial construction. While copper piping itself is relatively inert, the traditional solder used to join copper pipes historically contained lead at concentrations of 40% to 50%. Although lead-free solders (containing tin and silver) are now specified in new construction, compliance is not universal, and buildings constructed before 2010 are particularly likely to contain leaded solder joints. Additionally, brass fittings, taps, valves and connectors, can contain up to 8% lead by mass under older KEBS standards. Newer NSF/ANSI 61-compliant fittings are restricted to 0.25% lead. Plumber installing copper pipes. How Lead Enters Your Drinking Water Lead does not dissolve continuously from pipe joints into flowing water. The problem is stagnation. When water sits in contact with leaded solder or brass fittings overnight, the slightly acidic water dissolves trace amounts of lead from the metal surface. The longer the stagnation period, the higher the lead concentration in the first litres drawn from the tap. Health Effects of Lead in Drinking Water The WHO states that there is no safe level of lead exposure. At low chronic exposure levels, lead accumulates in bone, kidney and brain tissue. Children under five and pregnant women are most vulnerable, even low blood lead levels impair cognitive development and reduce IQ. Lead exposure has no visible symptoms at the levels typical in drinking water. The Flushing Rule, and Its Limits Occupational health guidance recommends flushing the cold tap for 30–60 seconds before drawing water for drinking or cooking in buildings with suspected leaded plumbing. This clears the standing water in the immediate pipe run. However: Flushing does not help for systems with elevated lead in the main building riser or service connection. It requires consistent behavioural change, easily forgotten during high-demand periods. It wastes significant water in the context of Nairobi's rationed supply. A More Reliable Approach RO membranes reject dissolved lead at rates of 95–99%. A point-of-use RO system fitted to the kitchen tap provides reliable, automatic protection without requiring occupant behaviour change. Testing your water annually for lead and copper in a new building is also recommended to establish a baseline and monitor for changes. Q: Does copper in my water indicate a health problem? A: Copper at low levels (below 2 mg/L WHO guideline) has no adverse health effects and is actually an essential trace mineral. At higher levels, acute copper toxicity causes gastrointestinal distress. Newly installed copper pipes can contribute elevated copper in the first few months of use, which typically normalises. Protect your family from lead in plumbing iClear's RO systems remove up to 99% of dissolved lead from your drinking water. Find out more.

Biofilm in Your Household Pipes: The Contamination Risk Nobody Talks About

Biofilm, a community of bacteria embedded in a protective matrix on pipe walls, is present in virtually every plumbing system. During low-flow periods it can shed into drinking water. RO filtration at the tap eliminates this risk. What Is Biofilm? Biofilm is a structured community of microorganisms that attach to a surface and produce a protective extracellular matrix. In household plumbing, bacteria from the municipal supply or from the surrounding environment colonise pipe walls within days of installation. The matrix protects them from chlorine disinfection and from being flushed out by normal water flow. Research published in Frontiers in Microbiology identified over 2,000 distinct bacterial species in household plumbing biofilms across multiple countries, including potential pathogens such as Legionella, Pseudomonas aeruginosa, and Mycobacterium species. When Biofilm Releases Bacteria into Your Water Under normal steady flow conditions, biofilm remains attached to pipe walls. Detachment events, which can introduce biofilm fragments and free bacteria into your drinking water, are triggered by: Water hammer: sudden pressure surges when taps are closed quickly. Extended stagnation: water sitting in pipes overnight or during holidays provides no flow to carry away detaching fragments. Pressure fluctuations: common during water rationing and valve operations by the utility. Hot water at scalding temperatures (>60°C) followed by cold water can cause thermal shock and biofilm detachment. Pipe repair work upstream: pressure changes during repair operations dislodge accumulated biofilm over a wide area of the distribution system. Chlorine Resistance of Biofilm Biofilm is 1,000 times more resistant to chlorine than free-floating (planktonic) bacteria. The extracellular matrix acts as a physical and chemical barrier, reducing chlorine diffusion to the inner layers of the biofilm by 70–90%. This means that standard municipal chlorination levels (0.2–0.5 mg/L residual) are insufficient to eliminate established biofilm. The Point-of-Use Solution Because biofilm can be present in the entire length of distribution pipe between the treatment plant and your tap, treating water at the source (the utility) does not guarantee clean water at the tap. A point-of-use filter, particularly an RO system, provides a final physical barrier that removes bacteria, biofilm fragments and their metabolic byproducts at the point of consumption. Q: Is Legionella a real risk in Nairobi households? A: Legionella grows preferentially in warm water (25–45°C) and is most associated with hot water systems, cooling towers and showerheads. The risk is low in normal household cold-water systems but higher in hot water storage tanks not maintained above 60°C. Q: Can I remove biofilm from my pipes? A: Physical removal requires professional pipe flushing and hyperchlorination, a periodic maintenance task for large buildings. For household drinking water, point-of-use filtration is the practical protection. Clean water at the tap, always iClear's point-of-use RO system provides protection from biofilm bacteria regardless of what happens in your building's pipes. Find out more.

Does Your Water Purifier Actually Remove Pesticides?

Reverse osmosis removes 90 to 99% of common pesticide residues including organochlorines and organophosphates. Boiling and standard carbon filters have limited effectiveness against dissolved pesticides. Pesticide Use and Water Contamination in Kenya Kenya is one of East Africa's most intensive users of agrochemicals. The Rift Valley, Mount Kenya region and the shores of Lake Naivasha are major horticultural zones where pesticides are applied extensively. Runoff from these areas enters rivers, reservoirs and groundwater that supply millions of households. A study published in Environmental Monitoring and Assessment found detectable organochlorine pesticide residues in 74% of groundwater samples taken from horticultural farming areas in Nakuru County, with some samples exceeding WHO provisional guideline values for lindane (γ-HCH). Source: Organochlorine pesticides in groundwater, Nakuru County, PubMed. How Different Pesticides Behave in Water Pesticide Class Examples Behaviour in Water Removal by RO Organochlorines DDT, lindane, endrin Persist in sediment and fatty tissue; low water solubility 95–99% Organophosphates Chlorpyrifos, malathion Moderately water-soluble; hydrolyse slowly 90–96% Carbamates Carbofuran, aldicarb Highly water-soluble; mobile in groundwater 85–92% Pyrethroids Cypermethrin, permethrin Low solubility; bind to sediment 94–98% Glyphosate Roundup herbicide Highly water-soluble; widely detected >90% What Different Purification Methods Achieve Not all water treatment methods are equally effective against dissolved pesticides: Boiling: Has no effect on dissolved pesticides, it concentrates them by removing water as steam. Reverse osmosis: Forces water through a membrane with sub-nanometre pores, physically excluding pesticide molecules regardless of their water solubility. Consistently achieves 90–99% removal across most pesticide classes. Ultrafiltration alone: Effective for particles but most dissolved pesticide molecules are too small to be excluded. The Importance of Carbon Pre-Treatment For maximum pesticide removal, a multi-stage system combining activated carbon with RO offers the best results. The carbon stage captures organic compounds and protects the RO membrane from chlorine degradation, while the RO membrane provides the final physical barrier. This is the configuration used in iClear's Standard and Office purifiers. Q: Do I need to worry about pesticides if I use municipal water? A: Municipal treatment (flocculation, sedimentation, chlorination) removes some pesticides but is not designed to achieve the low residual levels possible with RO. RO remains the recommended technology for households near agricultural zones. Q: Is glyphosate being detected in Kenyan water? A: Glyphosate use is widespread in Kenya. While national monitoring data is limited, regional studies across sub-Saharan Africa have detected glyphosate in surface water near agricultural areas. RO is effective at removing it. Clean water, regardless of what's upstream iClear's carbon + RO combination tackles pesticides, sediment and biological contaminants in one system. Find out more.
