There are a great many companies selling water filtration in Dubai, ranging from long-established businesses with workshops and technicians to a man with a van and a website built last month. The machines they sell overlap heavily. The difference between a good purchase and a bad one is usually not the box on the wall — it is who you bought it from and whether they are still answering the phone in year three.
What follows is a set of questions worth putting to any company you are considering, including us. We have tried to write it as advice rather than as an argument for ourselves, which means some of these questions are ones we would rather you did not ask. Ask them anyway.
The questions worth asking
Is there a trade licence and a real address?
In the UAE every legitimate business holds a trade licence, and any company should be able to give you its licensed name and licence details without hesitation. The licensed name is often not the brand name — WaterClub trades as Collector Filters and Purification Devices Trading LLC, and there is nothing unusual about that. What matters is that the entity exists, that it is licensed for what it is selling you, and that there is a physical address behind it rather than a mobile number and an Instagram page.
The reason this matters is not fraud, which is rare. It is continuity. Your relationship with this company is a multi-year one, and a business with premises, staff and a licence to lose is a business likely to be there for the second and third cartridge change.
Who actually installs it?
Ask directly whether the person coming to your home is an employee of the company or a subcontractor booked for the morning. Both exist in this market and neither is automatically wrong, but the distinction has consequences.
An employed technician is trained by the company, accountable to it, and will often be the same person who returns for servicing. A subcontractor nobody vouches for may be excellent or may be doing this work for the first time, and when something goes wrong six weeks later the question of who is responsible becomes murky in exactly the way you do not want it to be.
While you are asking, get the timings. Every under-sink and counter-top system should be a 20 to 45 minute job. A full villa system, installed next to the water tank, is 3 to 4 hours. Adding a chiller adds at least 2 hours. If someone quotes you fifteen minutes for a villa, they have not understood the job.
What happens in year two and year three?
This is the single most useful question on the list, and the one most often skipped in the excitement of comparing machines.
The machine is the cheap part. The maintenance is the commitment. Cartridges are changed roughly twice a year for as long as you own the system, so over any realistic ownership period the servicing outweighs the purchase. A company quoting an attractive machine price while being vague about servicing is not necessarily hiding something, but you are being shown half the number.
Ask what the annual plan covers, what it costs, and whether the cartridges are included in that or billed separately on the day. Ask what happens to the warranty. The normal arrangement is 12 months of warranty plus 12 months of maintenance to start, with an active maintenance contract keeping the warranty alive from year two onwards — so a lapsed plan is not only a missed service, it is the end of the cover.
Are the cartridges proprietary or standard?
Some systems take widely available cartridge sizes. Others take cartridges made only for that machine, available only from the company that sold it to you.
Proprietary is not automatically bad — it can mean a properly engineered, well-matched set of stages. But it is lock-in, and you should walk into it with your eyes open, because it means the price of servicing is set by a supplier you cannot change without replacing the machine. Ask what a replacement cartridge costs today, in writing, before you buy rather than after. Ask whether anyone else can supply it. If the answer to the second is no, weigh the first much more heavily.
Is the price on the website the price you pay at checkout?
Put the thing in the basket and go as far as the payment page. It takes two minutes and it tells you a great deal.
Look for delivery charges appearing at the end, installation quoted as an extra having been implied as included, and VAT being added on top. In the UAE, prices shown to consumers should already include VAT, so a figure that grows by 5% at the final step is a flag. At WaterClub the advertised price is the price paid, with delivery and installation both included, and you can check the same on any company’s site in two minutes.
Is anything appearing at the end that was not advertised?
Related but broader. Mandatory first-year service plans that were not mentioned, an “installation kit” line item, a mounting charge, a call-out fee on a warranty visit. None is inherently dishonest — a company is entitled to charge for its work — but all should have been visible before you decided, not after.
The tactics to walk away from
Now the other half. These are sales techniques rather than products, and they are common enough here that most residents will meet at least one.
The free water test
Somebody offers to come and test your water at no charge. What arrives is a sales visit with a prop.
The honest position, which costs us something to state: selling filters and testing water are two different businesses, and we are in the first one. WaterClub is not a laboratory. We cannot tell you what is in the water at your tap, and neither can anybody else standing in your kitchen with a handheld device. Genuine water analysis is done by an accredited testing laboratory, on a collected sample, and it produces a document. If you want that, commission it independently from someone with no machine to sell you.
A doorstep reading, whatever it displays, is not analysis. It is a number chosen to look alarming.
The demonstration where the water turns brown
This one deserves explaining properly, because it is genuinely persuasive to watch and it is nonsense.
The demonstrator puts two metal electrodes into a glass of your tap water and passes a current through it. Within a minute the water clouds, then turns orange-brown, and a scummy sludge forms on top. It looks exactly like proof that something disgusting was hiding in your water. Then the same test is run on filtered water from their machine, which stays clear.
What you are watching is electrolysis, and the brown material is iron, coming from the iron electrode, which is corroding in front of you. It is not coming from the water. The reason the tap water reacts is that it contains dissolved minerals, which conduct electricity and allow the current to flow, which corrodes the electrode. The reason the filtered water stays clear is that a reverse osmosis membrane has removed most of the dissolved content, so very little current flows and the electrode barely corrodes.
The test measures conductivity and nothing else — we have pulled the whole trick apart in what a TDS meter really tells you. Run it on premium bottled mineral water and you get the same brown sludge, for the same reason, which is a demonstration worth requesting on the spot if anyone tries this on you.
Any health or disease claim
If a salesperson connects their product to any illness, medical condition or effect on the body, end the conversation there. Claims of that kind have no place in a conversation about filtration.
These claims are not permitted, they are not supported, and a company willing to make them about health is a company willing to make them about anything else, including what its machine actually removes. A filter improves the taste, smell and quality of water you drink. That is a real, worthwhile and sufficient benefit. It does not need to be inflated into medicine.
Pressure to sign today
The discount that exists only during the visit. The manager telephoned for special approval. The last unit at this price. The offer that expires when the salesperson stands up.
A price that only exists if you decide now is not a price, it is a technique — and its function is to prevent you doing exactly what you should be doing, which is comparing two or three companies over a couple of days. Nothing about a water filter is urgent. If an offer is genuine it will survive until Thursday, and any company that means it will confirm that in writing.
What good looks like
Reasonable questions, answered before recommendations are made. Where the property is, whether it is a flat or a villa, whether there is a storage tank and who maintains it, how many people live there, what the water is for. A company that recommends a specific machine before establishing any of that is guessing, however confidently.
Straight answers about limits is the other marker. Filtration does not cool water — a standard system delivers it at tap temperature, which here is warm for much of the year, and cold water needs a chiller in the machine. Sparkling water is not available on domestic under-sink or counter-top systems at all. A whole-villa system cannot be honestly priced over the phone, because it depends on the tank, the plumbing and how the house is used, which is why it is quoted after a site visit rather than from a list.
If you would rather start from your own home than from a sales conversation, our filter finder asks the questions above in order and takes a couple of minutes, the comparison table puts the machines side by side with their stages listed, and our guide to what a filter really costs works through the multi-year number rather than the day-one one. Use them to interrogate us as readily as anyone else.
