Water filter prices in Lagos by type

The gap between prices can reflect the brand, capacity, included filters, warranty, pump and storage tank—not simply the number of “stages.” Marketplace prices also may not include delivery, plumbing or installation.

What affects the total cost of water filter?

The system price is only one part of your budget. Ask for a written quote that shows:

• Installation and plumbing: Is fitting the unit, adding a drinking-water tap and commissioning included?

• Pre-treatment: Does your source water need a sediment filter, iron or hardness treatment, or a booster pump?

• Replacement parts: What do the compatible cartridges, RO membrane or UV lamp cost, and how often should each be replaced?

• Warranty and service: How long is the warranty, what does it cover, and can you buy replacement parts in Lagos?

• Water testing: Is the recommendation based on a test of your own borehole, tanker, well or public supply?

The NSF guide to home water treatment recommends identifying the contaminants in the water first. It also explains that filters do not all reduce the same contaminants. If a product claims NSF/ANSI certification, check the exact model and reduction claim: for example, standards differ for aesthetic effects, health-related contaminants and RO systems. “Five-stage” by itself is not proof that a system removes a particular contaminant.

Why test your water before choosing a suitable water filter?

Water conditions can differ by source and property, so a filter that suits one home may not suit another. hjowever, water quality from souce changes with time.

Lagos Water Corporation describes physical and chemical, microbiological, and comprehensive water-analysis services through its Water Quality Assurance Department; confirm current availability and charges before submitting a sample.

Two public data points show why testing and clear product claims matter, but they do not tell you whether your own water is safe today:

• The 2024 Nigeria Demographic and Health Survey reports that 92.7% of Lagos respondents’ household population used no household water treatment, while 6.7% used an appropriate treatment method. See the Federal Ministry of Health and Social Welfare report.

• UNICEF’s 2021 Lagos WASH profile reported E. coli contamination in drinking water in 34% of households. This is a survey result from that study, not a current test of any individual home. Read the UNICEF Lagos State fact sheet.

For public-health guidance, see the WHO Guidelines for Drinking-water Quality. A filter should be selected for a tested or otherwise identified water-quality need, installed correctly and maintained on schedule.

Which water filter should you buy in Lagos?

• Choose a faucet filter only after checking faucet fit and the filter’s specific performance claims.

• Consider a gravity dispenser if you want a non-plumbed option, and confirm the cost and availability of replacement candles.

• Consider RO if the test results and treatment goal call for it. Confirm water pressure, drain connection, storage capacity, reject-water handling and replacement costs.

• For a whole building, office or commercial site, request a site assessment; those systems are priced by flow rate and source-water conditions.

Do not choose by stage count or “alkaline” wording alone. Check the exact model, certification, supported contaminant claims, warranty and maintenance schedule.

Frequently asked questions

How much does a water filter cost in Lagos?

Current online listings checked on 22 October 2026 range from about ₦4,500 for a basic faucet-mounted filter to ₦465,000 for a household RO system. Gravity dispensers commonly appeared around ₦45,000–₦109,000, while listed home RO systems ranged from ₦150,000–₦465,000. Installation and maintenance may be additional.

How much does it cost to install a water filter in Lagos?

Installation prices depend on the unit, plumbing, water pressure and any pre-treatment needed. Ask the installer to separate equipment, labour, fittings, testing and first-year servicing in the quote.

Is an RO filter always the best choice?

No. Select a system based on your water source and treatment goal. A properly certified filter for one contaminant may be a better fit than an RO unit, and every system still needs maintenance.
