Thinking about buying a Maverick Mav 02 water filter and wondering whether it's actually worth it?
We've analysed real Maverick water filter reviews to find out what buyers really think after installing it in their homes.
Unlike many under-sink filters, Maverick isn't just marketed as a way to improve taste. It also claims to help reduce limescale, making it particularly interesting for hard water homes.
The question is: does it actually live up to those claims in real kitchens across the UK?
Quick verdict: Is Maverick worth it?
For most people, yes.
91% of reviewers rated it 5 stars
Better tasting water was the most common benefit
Many customers stopped buying bottled water
Several reviewers reported less limescale in their kettle
Easy installation was mentioned repeatedly
If you're looking for a drinking water filter that also helps with visible kettle limescale, Maverick stands out from many competing under-sink systems.
Most product reviews give you one person's opinion.
This isn't one person's opinion.
We've analysed dozens of Maverick Trustpilot reviews from buyers across the UK to uncover the recurring themes — the things customers genuinely love, the frustrations that come up, and whether the product lives up to its promises in everyday use.
Let's see what real customers had to say.
Maverick water filter review breakdown
Here's how the reviews stack up overall.
91% Positive (5 stars)
The overwhelming majority of customers were delighted with their purchase. Better tasting water, reduced reliance on bottled water, easy installation and less limescale were the most common themes.
0% Neutral
Interestingly, the reviews were highly polarised, with almost no middle-ground opinions.
9% Negative (1 star)
The negative reviews focused mainly on delivery issues, customer service concerns and trust rather than the filter's performance.
What people loved
Better tasting water
This was the biggest theme by some distance.
Many reviewers described the water as cleaner, fresher and easier to drink. Several compared it favourably to bottled water, while others said they stopped buying bottled water altogether after installing Maverick.
For many households, the taste improvement alone was enough to justify the purchase.
Less limescale in hard water areas
This is where Maverick gets particularly interesting.
Several reviewers specifically mentioned living in hard water areas and reported seeing less limescale after installation.
The most common observation was reduced kettle scaling, with some customers saying they had seen little or no limescale build-up since fitting the filter.
It's important to note that Maverick is not a water softener and won't remove hardness minerals in the same way a salt-based softener does.
However, based on customer feedback, many users clearly feel it has made a noticeable difference to visible scale build-up in their drinking water appliances.
Our take:Â The limescale feedback stood out. Multiple reviewers independently mentioned seeing less scale in their kettle, which isn't something we often see with standard inline filters.
Easy installation
Installation came up repeatedly in positive reviews.
Many customers reported fitting the filter themselves within minutes and appreciated the straightforward instructions.
That said, a few homes required additional connectors, pipework or plumbing help depending on the existing under-sink layout.
Better value than bottled water and filter jugs
Several reviewers compared Maverick to:
Bottled water
BRITA filter jugs
Water2
Fridge filters
Many felt Maverick offered a more convenient long-term solution because the filter lasts significantly longer than a typical jug cartridge.
The red flags
Customer service concerns
Most reviews were extremely positive, but the negative reviews tended to focus on communication rather than filtration performance.
A handful of customers reported issues with delivery, responses or general customer service.
While these reviews were in the minority, they're worth noting.
Installation won't be plug-and-play for everyone
Although many customers found installation simple, some needed additional fittings or help from a plumber.
If your pipework is unusual or access is limited, installation may be slightly more involved than the marketing suggests.
The good stuff? It's genuinely impressive
For 91% of reviewers, Maverick delivered exactly what they were hoping for.
The strongest themes were better tasting water, less reliance on bottled water and surprisingly positive feedback around kettle limescale.
For hard water homes, that's what makes Maverick stand out from many competing under-sink filters.
The not-so-great bits?
The main concerns relate to customer service rather than filtration performance.
Issues were not widespread, but they're worth factoring into your decision.
Cost upfront and ongoing
Maverick costs around ÂŁ110 upfront, making it competitively priced compared to many under-sink filtration systems.
One of its biggest advantages is the ongoing running cost. Replacement filters typically cost around £45–£50 per year, which is noticeably cheaper than some competing brands, including Water2 (£99 per filter).
Unlike filter jugs that require regular cartridge changes, Maverick only needs a single annual filter replacement. For many reviewers, that combination of convenience, better tasting water and relatively low annual running costs made Maverick good value for money.Â
Is Maverick right for you?
It's a good fit if
You live in a hard water area
You're fed up with constantly seeing limescale in your kettle
You want better tasting drinking water straight from the tap
You want an under-sink filter that includes dedicated anti-scale technology
You want a low-maintenance alternative to filter jugs
It's probably not for you if
You want whole-house soft water
You want to eliminate limescale throughout your home
You don't want any installation work
You're looking for the absolute cheapest filtration option
Does Maverick actually help with limescale?
Maverick is the only inline under-sink filter we've found that includes a dedicated anti-scale stage. And according to several customers, it appears to make a noticeable difference.
Multiple reviewers in hard water areas reported less limescale in their kettle after installation, with some saying they saw little or no visible scale build-up.
It's important to keep expectations realistic: Maverick isn't a water softener and won't eliminate limescale throughout your home. But if your main concern is the water you drink, boil and use in hot drinks, the customer feedback is certainly encouraging.
Maverick vs Water2
If you've been researching under-sink filters, you've probably also come across Water2.
Both systems improve drinking water taste and fit neatly under the sink, but there is one important difference.
Water2 focuses primarily on reducing contaminants and improving taste. Maverick's Mav 02 is one of the few under-sink filters that also includes an anti-scale stage and specifically targets hard water issues.
That's reflected in the reviews too.
While Maverick customers frequently mention reduced kettle limescale, that's not something commonly reported in Water2 reviews.
If your main goal is simply better tasting drinking water, both are worth considering. If you're specifically trying to tackle hard water and kettle scale, Maverick has a clearer advantage.

Still unsure?
Maverick sits in an interesting middle ground.
It's more capable than a filter jug, cheaper than many premium reverse osmosis systems from brands like Waterdrop, and one of the few under-sink filters receiving consistent customer feedback around limescale reduction.
If your biggest frustrations are poor tasting water and kettle scale, the Maverick water filter reviews suggest it's well worth considering.

Maverick Mav 02 filter FAQs
Does Maverick soften hard water?
No. Maverick is not a water softener and won't remove hardness minerals in the same way a salt-based softener does. However, several customers reported less visible limescale in kettles and drinking water appliances after installation.
Is Maverick better than Water2?
If your priority is hard water and limescale, Maverick appears to have an advantage because it includes anti-scale technology. If your priority is simply better tasting drinking water, both are strong options.
Is Maverick worth it?
Based on the reviews analysed, most customers believe so. Better tasting water, reduced bottled water purchases and positive feedback around limescale reduction were the standout benefits.
Does Maverick filter both hot and cold water?
No. The Maverick Mav 02 is installed on your cold water supply only, so it filters the water that comes out of your kitchen cold tap.
That's actually how most under-sink drinking water filters work. Hot water isn't usually filtered because it passes through your boiler or hot water system first, and most people primarily want filtered water for drinking, cooking, tea and coffee.
Do you need a separate filter tap?
No. One of the advantages of Maverick is that you keep your existing kitchen tap.
Unlike some reverse osmosis systems that require a dedicated drinking water tap, the Maverick Mav 02 connects to your existing cold water line under the sink. That means you can enjoy filtered water straight from your normal kitchen tap without drilling extra holes in the worktop or changing the look of your kitchen.
Does Maverick reduce limescale?
Based on the customer reviews we analysed, many users reported seeing less limescale build-up in kettles after installing the Maverick Mav 02. Several reviewers in hard water areas specifically mentioned reduced or no visible kettle scale.
However, Maverick is not a water softener and won't remove hardness minerals throughout your home. If your goal is complete whole-house limescale protection, you'll need a water softener. If you're mainly concerned about drinking water and kettle scale, Maverick may be a more affordable alternative.
Is Maverick difficult to install?
Most reviewers found installation straightforward and many fitted it themselves in under an hour. However, some homes may require additional fittings depending on the existing pipework under the sink. If you're not confident with basic plumbing, it's worth asking a plumber to install it for you.
