Busy routine, right?
Picture your usual week: the big shop, the school runs, the endless washing. Then there's bottled water. Loading heavy multipacks into the trolley, carrying them home, and watching empty plastic pile up. After that comes another chore: taking bottles back, queuing at the return machine, and feeding them in one by one to reclaim a few cent. It's a small task that quietly costs you time and money.
It does not have to be that way. So let us talk about water filters for your drinking water, how much looking after they really need, and why the right one can take that whole chore off your plate for good.
The two worries homeowners always have
When people think about fitting a water filter for home, two questions come up every time. How much hassle is the filter maintenance, and how long will it actually last? Both worries are fair, and both have reassuringly simple answers once you see how a modern water filter works.
Filter maintenance. A good water filter is not a needy thing. With our ArkkZ system, the filters use a twist and pull design and are changed once a year, so you can swap one yourself in seconds, no tools and no plumber needed. Across a whole year, keeping it serviced takes barely a minute. The system even sends you a reminder when a change is due, and we email you too, so you never have to keep track of dates yourself.
Lifespan. The filters are built to go the distance. The pre filter is usually changed about once a year, and the reverse osmosis membrane can last up to two years. With that light bit of upkeep, your water filter keeps delivering pure water day after day, quietly, in the background.
So the filter maintenance is tiny and the system lasts. That clears the path to the real question: which type of water is actually worth having at home?
Bottles, jugs, or reverse osmosis?
If you have ever stood in the kitchen weighing these up, here is the honest comparison.
Bottled water. It feels safe and easy, but it is the dearest option by a distance, and the chore never ends. Over four years, a family on bottled water gets through the equivalent of around 2,000 large bottles. That is a lot of shopping, lifting and recycling. And it is not even as clean as people assume. A 2024 study published in the journal PNAS found that an average litre of bottled water carries around 240,000 tiny plastic particles, most of them nanoplastics small enough to pass into the bloodstream. You are paying a premium to drink plastic.
Filter jugs. Cheap to buy and handy, and a step up from nothing. But they are slow, they live in the fridge taking up space, the cartridges need swapping constantly, and they only reduce a limited range of things. You are still topping up, still waiting, still buying refills.
Reverse osmosis. This is the water filter that actually solves the problem. It pushes water through a fine membrane that removes up to 99.99% of contaminants, then delivers clean water straight from a dedicated tap. After a one off filter installation, there are no bottles, no jug, no waiting and nothing taking up space on the sink. Just pure water on demand.
Why the ArkkZ is easy to keep and your best choice
For drinking water, this is our most popular system, and it is built to be easy to live with from day one.
I have recommended a lot of drinking water systems over the years, and the ArkkZ is the one I keep coming back to, for one simple reason. It gives you the purest water with the least fuss. Here is what actually sets it apart once it is sitting under your sink.
- It barely asks anything of you. This is the part that wins people over. The twist and pull filters change by hand in a few seconds, and the total upkeep across a whole year comes to little more than a minute. There is no no expensive tools, and no plumber. It is genuinely the least demanding appliance in most kitchens.
- It tells you when it needs you. You never have to remember a schedule. The system flags a reminder the moment a filter is due, and we email you as a backup, so a change never sneaks up on you.
- The filters go the distance. The filter lasts about a year and the reverse osmosis membrane up to two, so replacements are rare and cheap next to the bottled water they replace.
- It removes what matters. Reverse osmosis is the most thorough filtration you can put in a home, stripping out up to 99.99% of contaminants. That means chlorine, lead, mercury, microplastics and PFAS, along with the tastes and odours that put people off their tap water in the first place. For a parent filling a glass or making up a bottle, that peace of mind is the whole point.
- It gives the water back its taste. After the deep clean, a remineralisation stage adds back the healthy minerals like calcium and magnesium, so what reaches your glass is clean and crisp rather than flat.
- It saves your space and your storage. The tankless design saves up to 70% of the room a traditional system takes under the sink, so you keep your cupboard instead of losing it to a bulky tank.
- It is fast and never runs out. Because there is no tank to wait on, you get unlimited pure water straight from a dedicated tap, filling a glass in seconds. No jug to refill, no bottles to lug.
- We install it free. Across Ireland and Northern Ireland, we fit it for you, so there is nothing for you to organise or pay extra for.
Put simply, it is the system that does the hard work so you never have to. As our founder Simon Newell likes to put it, "Buy the filter, don't be the filter." Your body should not be doing the job your tap could do for you.
What the installation actually looks like
This is the other thing people quietly worry about, so let us put it to rest. Fitting the system is far simpler than most expect.
Once you have ordered, our team gets in touch to book a day and time that suits you. On the day itself, the whole job takes around two hours. One of our technicians connects the system to your mains supply and the drain under the sink, sets everything up, and makes sure it is working before they leave.
There are no holes to drill and no big changes to your kitchen. All we need is a power socket nearby and a bit of space under the sink. That is it. You go from ordering to pouring pure water from your tap without lifting a finger, and the whole thing is included free across Ireland and Northern Ireland.
