Updated: Jun 5
If you’re comparing Maverick vs Water2, or looking for a Water2 alternative, you’re probably trying to answer a simple question: Which filter actually tackles the issues you care about — and which one is right for your home?
Both are under-sink filters designed to remove contaminants and improve the taste of your water. But they take quite different approaches.
That’s why we’ve done the homework for you.
In this guide, I’ll break down how they compare — what they remove, how they work, what they cost long-term, and which one makes the most sense depending on what you want.
What each filter actually does (and what that means)
Maverick Mav 02
Uses a multi-stage “5-in-1” filter, which includes:
Activated carbon (for chlorine and taste)
Sediment layer (for dirt and particles)
Anti-scale filtration stage
Fluoride removal media
Silver-ion anti-bacterial protection
The goal is to tackle a wider range of contaminants in one system.
Water2 Pod 2.0
Uses a single filter:
High-grade activated carbon (for chlorine and taste)
In simple terms:
Maverick aims to cover more
Water2 focuses on the essentials
What do they actually remove?
Maverick filtration claims:
Chlorine — 99%
Microplastics — 99%
Lead — 99%
Limescale — 99% (reduction claim)
Fluoride — 70–99%
Viruses & bacteria — 99%
VOCs — 99%
Pesticides — 99%
PFAS — 50–90%
Sediment — 99%
Pharmaceuticals — 99%
Water2 focuses on:
Chlorine — 95%
Microplastics — 99.99%
Lead — 85%
THMs — 84%
A quick note on claims: Water2 states that its figures are based on third-party lab testing, so while it lists fewer contaminants, the performance data is independently verified. Maverick doesn’t currently publish detailed third-party test results for all of its claims, although its NSF 42 & 53 certification does support chlorine reduction and taste improvement.
Limescale reduction: one of the biggest differences
If you’re dealing with hard water, this is the bit that really matters.
Maverick claims to reduce up to 99% of limescale, while Water2 doesn’t make any specific limescale reduction claims.
The Mav 02 uses a dedicated anti-scale stage that changes how calcium and magnesium behave in the water. Instead of forming hard deposits, the minerals are kept in a form that’s less likely to build up in kettles, appliances and pipework.
In practice, that means you may see:
Less visible scale over time
Easier cleaning
From our experience working in hard water homes, it’s important to set expectations. This is about reducing scale build-up — not removing the minerals to give you soft water.
So you may not get:
Completely scale-free water, especially towards the end of the filter life
The same result as a full water softener or reverse osmosis system
Water2 doesn’t make any limescale claims, so if that’s a priority for you, Maverick has the edge — just with realistic expectations.
Limescale your main concern? Maverick has the edge ↗
Running costs: another key difference
When you have a water filter, it’s important to keep on top of filter changes — that’s what keeps the system working properly.
For standard use, both of these systems are designed around annual filter replacements:
Water2 Pod 2.0: £99 per year
Maverick Mav 02: £49.99 per year (or £44.99 with subscription)
So Maverick comes in at around half the ongoing cost. Over 3 years, that works out at roughly:
Maverick: £150
Water2: £300
That’s a noticeable difference, especially if you’re planning to keep the system long-term.
It’s worth noting that costs can change depending on how you use the filter. If you’re specifically targeting fluoride with Maverick, more frequent filter changes are recommended — which increases the yearly cost (covered in the fluoride section below).
But for general day-to-day use, Maverick is clearly the more cost-effective option.

Flow rate: a common reason people look for Water2 alternatives
Some people start searching for a Water2 alternative because of flow rate — either they’re concerned about it upfront, or they’ve tried the product and have experienced slower water flow over time, particularly towards the end of the filter’s life.
Water2 doesn’t currently publish a flow rate on its website, so it’s harder to know exactly what to expect in day-to-day use.
Maverick, on the other hand, quotes a flow rate of around 7 litres per minute, which is strong for an under-sink filter and should feel similar to a standard kitchen tap in most homes.
In practice, flow rate can vary depending on things like water pressure and how blocked the filter becomes over time. But having a published figure does give a clearer expectation — especially if a good water flow is important to you.
If maintaining good pressure is a priority, this is one area where Maverick has the edge ↗
Concerned about fluoride?
The standard Maverick Mav 02 filter includes a dedicated fluoride removal stage, something the Water2 Pod 2.0 does not offer. Though there is a catch, to keep it working effectively, the filter needs replacing roughly every 4 months (rather than once a year), and ideally used with a dedicated drinking water tap.
Water2 takes a different approach. Its standard filter doesn’t target fluoride, but you can buy a separate fluoride filter add-on if you want it.
So in practice, both can reduce fluoride — they just handle it differently.
Fluoride nice-to-have?
If fluoride reduction is more of a nice-to-have, Maverick has the edge. It’s included as standard, and you can still benefit from it without increasing your yearly cost — just with reduced effectiveness over time.
Fluoride a priority?
If fluoride removal is a priority, Water2’s add-on is the simpler option. The filters are designed to last a full year, and over 3 years it works out slightly cheaper (around £467 vs £506 for Maverick with filter changes every 4 months).
Maverick vs Water2 which should you choose?
For many people, Maverick is the most practical Water2 alternative — especially if you want better performance on limescale, flow rate and long-term cost.
It covers more, costs less to run, and works well as an all-round upgrade for most homes.
Best for broader filtration, limescale and lower cost: Maverick Mav 02
If you prefer something simpler and more established, Water2 is a solid choice. Its carbon-based system is straightforward, backed by clear lab-style data, and widely used — so you know what to expect.
Best for simplicity and proven performance: Water2 Pod 2.0

Maverick and Water2 alternatives
If neither of these feels quite right and you’re looking for Maverick or Water2 alternatives, there are a few different routes depending on what you want to improve — whether that’s taste, limescale, overall filtration or price.
On tap filters
If you want something cheaper and easier to install, on-tap filters are a great choice.
They attach directly to your kitchen tap, take a few minutes to fit, and still improve taste by reducing chlorine and some contaminants. They won’t match under-sink systems for performance, but they’re a low-cost, low-hassle option that's still an upgrade from a filter-jug.

Reverse osmosis
At the other end of the scale, if your main goal is fully tackling limescale, you’ll need something more powerful. Reverse osmosis (RO) systems remove dissolved minerals like calcium and magnesium, meaning you get genuinely soft water from your drinking tap.
They’re more expensive, but they’re one of the few options that properly deal with hard water at the source. From our experience running a plumbing company, we’ve fitted and tested Waterdrop reverse osmosis filters and rate them highly — they’re modern, well-built, and easy to live with day to day.
If you’re weighing this up, it’s worth reading our guide to reverse osmosis systems.
Water softeners
If you’re looking to treat all the water in your home (not just drinking water), a water softener is usually the most effective long-term solution. These systems remove hardness minerals before they reach your taps, helping to prevent limescale build up in showers, appliances and pipework altogether.
You can learn more in our guide to whether water softeners are worth it.
