If you live in a duplex, bungalow or flat anywhere in Lagos, Abuja or any estate in Nigeria, chances are your water comes from a borehole. Pipe-borne water from the government is unreliable in most areas, so the borehole and the overhead tank have become standard in almost every home.
But there is a difference between having water and having safe water. The raw water your pumping machine sends into your tank is rarely fit to drink. It may carry iron that stains your white tiles and WC, sand that blocks your taps, salt that spoils the taste of your tea, or bacteria you cannot see at all.
So what should it actually cost to make borehole water safe? Below is a clear breakdown of the water filter for borehole price in Nigeria for 2026, what each type of water purifier in Nigeria actually does, and how to pick the right system for your home.
Quick price guide
| What you want to solve | System you need | Typical price |
|---|---|---|
| Sand, particles, brownish water at one tap | Candle or resin cartridge filter | ₦2,500 – ₦20,000 |
| Iron stains on tiles, WC and clothes | Jumbo housing + iron removal filter | ₦35,000 – ₦150,000 |
| Treating the whole compound or an estate block | Whole house water filter / treatment plant | ₦650,000 – ₦2,500,000+ |
| Safe, great-tasting drinking water | Reverse osmosis water filtration system for home | From ₦450,000 installed |
Prices reflect the Nigerian market as of 2026 and will vary by brand, capacity and fittings.
1. Basic sediment and iron removal filter systems (₦20,000 – ₦150,000)
If your goal is simply to stop sand, mud and heavy iron from reaching your overhead tank, basic plumbing filters are the first step.
Candle and resin cartridge filters cost roughly ₦2,500 to ₦20,000 each. These are small point-of-use filters fixed to a single tap or a short run of pipe.
Jumbo filter housings and iron removal filters — the big blue cylinders your plumber installs near the pumping machine — usually cost between ₦35,000 and ₦150,000 depending on the brass fittings and the filter media inside. If your complaint is reddish water and stained tiles, an iron removal filter at the pumping machine is the cheapest fix available.
These are worth doing. They protect your plumbing, your tiles and your washing machine. What they will not do is make the water safe to drink.
2. Whole house water filter systems (₦650,000 – ₦2,500,000+)
A whole house water filter treats everything before it reaches your taps. Industrial stainless steel filtration tanks filled with sand, activated carbon and iron removal filter media handle thousands of litres per hour.
Quotes vary widely, so get at least three before committing. A small-scale plant starts around ₦650,000, while multi-stage systems sized for a large duplex or an estate block run to ₦2,500,000 and beyond. For perspective, drilling and equipping an entire borehole for a five-bedroom Lagos duplex — the hole, the casing, the pump, the tank and basic treatment — typically costs ₦800,000 to ₦2,500,000, so a serious whole-house plant can cost as much as the borehole that feeds it.
What drives the price is capacity, the number of treatment stages, the grade of the tanks, whether a softener or UV stage is included, and how much re-plumbing your compound needs. Installation and labour on a large duplex often cost as much as the equipment itself, and few vendors quote that upfront.
A whole house system makes sense if you are treating an entire estate block, a hotel or a factory, or if your iron problem is severe enough to be damaging appliances throughout the house.
But be clear about what it does not do. A whole house water filter is not a drinking water solution. It removes what is visible — sand, iron, sediment — and leaves dissolved salts, heavy metals and bacteria in the water. Households that install one almost always keep buying dispenser bottles afterwards, because the kitchen tap still is not safe. That is the part nobody tells you before the invoice.
3. Reverse osmosis water filtration system for home use — the iClear solution
Even with a good iron filter on your pumping machine, the water reaching your kitchen tap is still not drinking water. Iron filters catch what you can see. They do not remove dissolved heavy metals, salt, or the bacteria that cause typhoid and cholera.
That is the gap iClear fills. Our reverse osmosis water filtration system for home use installs directly under your kitchen sink and delivers bottle-quality water at the tap — no dispenser bottles, no pure water, no boiling and storing in the fridge.
Instead of spending millions on an industrial plant just to get drinking water, you treat the water at the one point where it actually matters.
How ₦450,000 compares to the rest of the RO market
Most residential reverse osmosis systems sold in Nigeria are quoted between ₦800,000 and ₦2,500,000. Some suppliers put home water treatment equipment in the ₦450,000 to ₦1,500,000 band, with anything commercial-grade starting above ₦1,500,000.
At ₦450,000 fully installed, iClear sits at the bottom of that range — not because the system is cut down, but because we build for one job. We are not selling you capacity to treat your bathrooms and your garden hose. We are purifying the water your family actually drinks, at the tap where you actually drink it, and pricing it accordingly.
If your water tastes salty, RO is the only real answer
Boreholes across Lekki, Ajah, Ikoyi and Victoria Island draw brackish water. You will know it by the taste in your tea, the white scale in your kettle, and soap that refuses to lather properly.
No amount of sand, carbon or iron-removal media will fix this. Salt and dissolved solids are far too small for those filters to catch. Reverse Osmosis is the only home technology that removes them, which is why RO is now standard in serious homes along the Lagos Island axis.
Before you buy: five questions Nigerians should always ask
Will it work when NEPA takes light? An RO system uses a small booster pump. iClear units run comfortably on an inverter or generator, and the storage tank holds purified water so you still have drinking water when there is no light.
Do I need a booster pump? If your overhead tank sits low or your pressure is weak, yes — and it should be included in the quote, not sprung on you on installation day. Confirm this before paying.
Where will I buy replacement filters in two years? This is the question that separates a real supplier from a one-time seller. Ask whether replacement cartridges are stocked in Nigeria and what they cost. iClear stocks all replacement filters locally.
Does RO waste water? It does reject some water during purification — that is how the membrane works. Most homes simply channel the reject line into a bucket for washing, cleaning or flushing the WC, so nothing is truly wasted.
Is there a warranty and who installs it? Free professional installation and a written warranty should be standard. If a vendor drops the unit at your gate and disappears, that is a warning sign.
Do not cut corners on drinking water
When you compare the water filter for borehole price in Nigeria, be careful not to confuse sediment removal with purification. A ₦15,000 filter tap will catch sand. It will not stop typhoid, cholera, or dissolved heavy metals.
And compare the right things. A whole house water filter is not an alternative to an RO purifier — it sits upstream of one. Install a whole house system alone and you will still be buying dispenser bottles next year, and the year after that.
So run the numbers on what you are already spending. A household getting through two dispenser bottles a week spends well over ₦100,000 a year on drinking water, every year, forever, and owns nothing at the end of it. An iClear RO system at ₦450,000 installed clears that spend in roughly four years and then keeps paying you back for the life of the unit. The only ongoing cost is replacement cartridges.
FAQ
Q: How much does a water filter for a borehole cost in Nigeria?
A: The water filter for borehole price in Nigeria depends on what you are solving. A basic sediment or iron removal filter for general household use costs between ₦20,000 and ₦150,000. A whole house water filter runs from about ₦650,000 to ₦2,500,000 once installation is included. For drinking water specifically, a reverse osmosis water filtration system for home use starts from ₦450,000 installed — against a market where most residential RO systems are quoted between ₦800,000 and ₦2,500,000.
Q: Will a basic borehole filter make my water safe to drink?
A: No. A whole house water filter or jumbo filter removes large particles like sand and heavy iron. Bacteria, dissolved salts and heavy metals pass straight through. You need an RO purifier for drinking water.
Q: Which water purifier in Nigeria is best for borehole water?
A: For borehole water, look for a multi-stage reverse osmosis system rather than a simple carbon or candle filter. Borehole water in Nigeria commonly carries iron, dissolved salts and bacteria at the same time, and only RO handles all three. Make sure replacement cartridges are stocked locally before you buy.
Q: My borehole water is salty. Can it be fixed?
A: Yes, but only with Reverse Osmosis. Salt is dissolved in the water, so sand and carbon filters cannot remove it. RO membranes can.
Q: Does the purifier work without light?
A: The system stores purified water in a tank, so you still have drinking water during outages. It also runs on inverter and generator power.
Q: Does iClear install purifiers for borehole water?
A: Yes. iClear Reverse Osmosis systems are built specifically to take standard Nigerian borehole water and turn it into safe, great-tasting drinking water. We offer free professional installation across Lagos and Abuja.
