As the UK’s water filter experts, we’ve seen quite a few different filter types come and go.
Tap water filters, as you saw in the graph above, have become widely used in recent years in the UK.
What do we think of them? Well, it wasn’t always the case (some older models had the main technology of the placebo effect 😉 but now they offer good quality filter technology, for a unit that’s small and light enough to be attached to your battery.
How did we pick these winning options for someone who wants a water filter for their tap?
We analysed:
- The quality of filtration technology
- Suitability for a wide range of tap types
- Flow rate (and whether the reality matches the product’s stated flow rate)
- Whether or not it improve the water’s healthiness or just removes contaminants
- Ease of use
- Ease of installation
- Build quality and component hardiness
Finally, we’ll talk about how to choose which type you need and which model best fits your requirements.

Tap Water Filter Reviews
Let’s get to grips with the top water filters for taps in the UK.
We’ll look at the pros and cons of each model, and rate them accordingly.
Brita On Tap V System
Pros and who needs this :
It’s the best overall tap filter
This is the tap filter that ticked the most boxes of the crucial aspects we’re looking for. It has the strongest filtration power (more on that later), fits well on the vast majority of taps with a good adapter system, and it has the top level of materials that you’d expect from a brand like Brita, so it’ll last well.
Cleverly designed four levels of filtration
We’re impressed with the quality of filtration provided by the Brita tap filter. They manage to combine the best aspect of the Xntong model’s filter (one of the best on the market in a previous version of this article but no longer available in the UK), the coconut shell variety of activated carbon, with the best aspect of the Waterdrop filter – the nonwoven filter media. We rate it as the best filter for removing the most contaminants and therefore the one that provides you with the healthiest water.
The 3 modes work well
Like the Philips On-Tap filter, it has three operating modes: filtered, unfiltered, and unfiltered shower. The third mode, as it sounds, is ideal for a shower-type water stream, ideal for washing dishes. We liked the Brita model’s system best, it makes it very easy to shift between each mode, and the shower stream is better than the Philips model.
Backed by exceptional lab results to prove its filtration efficiency across a huge range of contaminants and impurities
We really like Brita’s openness to publish their lab results showing exactly what their tap filter removes and what it doesn’t. And the percentages for each type. That means if there’s a specific chemical or metal you’re keen to remove from your drinking water, you can check and be confident that it removes it. Check out Brita’s water filters or go directly to the filter performance data sheet.
Cons and why this model is not for you:
It has the filter with the shortest lifespan
Brita recommend a maximum of 600L of water per filter. The other models on this list offer as much as 1200L. All else being equal, then, it’ll last half as long. One aspect to bear in mind is that this Brita filter is also the most powerful, so it’s perhaps natural that it wouldn’t be as long-lasting as the rest.
It’s the most costly
It’s the tap water filter that costs the most out of these winning models in this article. And it has the shortest filter cartridge lifespan, so you’ll also need to spend more on filters each year. Weigh up if you’re willing to pay the price for the Brita quality.
Where is the best place to get it?

Philips Water On-Tap Water Filter
Pros and who would need this model:
Filter quality is very high
It’s triple stage microfiltration. One of these stages is granular activated carbon, a high quality filter type. In our tests, we found that it worked really well to remove lots of different contaminants. Like what? Like chlorine, PFAS, pesticides, VOCs (volatile organic compounds). It works by adsorbing these impurities in its multitudinous (lots and lots!) of nooks and crannies within the carbon lattice network structure.
Particularly effective for odour removal
It worked really well for removing unpleasant smells from water. That’s because it has high efficacy at filtering out organic chemicals, like hydrogen sulfide and chlorine (which are responsible for most odours that can arise in your water).
Fitting is largely good
Water filters for taps have one major challenge to overcome compared to other filter types. While most water pipes and systems have just a couple of different sizes, these filters must tackle the thousands of different types of taps. Every tap water filter has adapters to deal with this challenge. We found that the Philips Water model had the best solutions to meet all the different types. So while some people may have an issue, the vast majority of people will find it works really well off the bat, and with quite simple installation. Philips offer a clear guide, a pictorial diagram showing which taps it doesn’t work with – make sure you check it before you buy! And it has a wide range of adapters to fit the type of tap that it is suitable for.
It performs well in each aspect
What’s why it’s the best overall. As mentioned above, it has the best adapters to fit different types of tap. We found it easy to install on most different types of tap. Operating it was smooth. It’s sturdy and well made – there’s a reason a reputable brand like Philips put their name on it. It’s not too heavy and not too big, compared to most models on the market.
Cons and why it’s not for you:
The water isn’t quite as healthy as the Waterdrop filter
Don’t get us wrong, the water output from the Philips On-Tap filter is great. Clean and healthy. But the Waterdrop tap filter adds back healthy minerals, and makes the water the healthiest we’ve seen for this filter type. This model can’t quite match this quality.
It’s a bit bulky
On sinks with not a lot of space between the tap and the sink surface, the Philips On-Tap can be too bulky an addition. If you have a sink/tap set up like that, do a check to see if you’re still going to have enough room to wash your dishes and fill your glasses. To a certain extent, it’s inevitable with this type of product that it’ll rob you of some sink space, but the design of this filter is not ingenious, and not particularly ergonomic.

Waterdrop Tap Filter WD-FC-06
Pros and who this is best for:
The best quality filtration on a water filter for taps
The 4 stages of filtration are very impressive for this filter type. Most tap water filters’ main filter media is a carbon filter, typically activated carbon of some kind. And one (most 2-layer filters) or two (most 3 layer filters) sediment filter nets. The Waterdrop filter has those, and then 2 additional layers that no other tap filter we’ve seen has. It also has a nonwoven filter. Nonwoven filters are great for filtration, made from a random, fibrous web of material, in this case polyester. And it also has a remineralisation filter layer…
Remineralisation layer
Remineralisation filters are generally only in highly expensive reverse osmosis filter systems. And reverse osmosis filters are indeed one of Waterdrop’s specialties. What do they do? They add back health-giving minerals to the water, such as magnesium and calcium. That’s why we describe the Waterdrop WD-FC-06 water filter as not only making the water safer but also improving your health. Good health is such a multifaceted, complicated web of real-life factors but something as basic as having mineral-rich, revitalising water to drink day by day is such an easy win.
Easily the best looking/most likely to look as though it fits with your sink aesthetic
Everyone will have different perceptions about the importance of this. But its silver, shiny colour (it’s made from a quality stainless steel), will match with your tap better than the vast majority of tap filters, that are made from plastic.
Excellent build quality
Some plastic tap filters are prone to breakages and cracks. Some metal ones can develop rust and from there, it’s not going to last you much longer or be great for your health. But the Waterdrop tap water filter’s build quality is really good, it just feels and looks more sturdy than the others we tested. Its anti-rust and crack-resistant stainless steel material is one of the key reasons for this. That’s what you get with Waterdrop, their specialty is water filters, and good quality ones at that.
Negatives and why it may not be for you:
Expensive
It’s not too far off double the price of the Philips Water On-Tap water filter. We’ll say the same thing we said before, though. Considering how much more safe and healthy it makes your water. It’s not just a couple of quid, no-one’s saying that. But though all you can see is a metal block, there’s really good quality filtration processes going on unseen, inside the unit. This is a worthwhile investment, if you can afford it of course.
Where can you buy it?
Here’s the lowest cost seller we found.

How To Choose The Right Tap Water Filter For Your Needs?
Here’s how to pick the best one for you.
How important is the quality/safety of the water for you?
If you want the absolute safest possible water, the Brita wins it based on filtration excellence. Both this filter and the Waterdrop WD-FC-06 are the market’s best in this regard. The nonwoven filter is a step up from the rest of the market, as is having 4 layers of filter media.
But we still have no hesitation to recommend all the tap filters in this article, including the Philips mode. It too provides more than enough protection to make your water safe.
Do you want a water filter for your tap that can make the water more healthy?
By that, we mean not just removing contaminants but actually giving the water more health-giving properties.
That’s what the Waterdrop filter will do, and why there’s even an argument that it provides healthier water than the Brita model. That’s due to its remineralisation filter. That’s a step beyond making your water safer. It actually increases the mineral quality of your water, and at safe levels.
Is water flow particularly important for you?
Water flow in all three of these filters is good; that’s one of our key criteria, and hence why they made this list.
But if it’s especially important for you that water flows really fast – not accusing you of being impatient or anything, though! ;), then perhaps choose the Philips water filter.
Filters Taps Can Remove Chlorine, Lead, PFASs, microplastics etc
Water filter taps have come a long way and are extremely effective for removing impurities like chlorine, lead, asbestos and VOCs.
In addition, hormones and pharmaceuticals can be extracted extremely efficiently.
For example, the Brita tap water filter can remove over 99.9% of microplastics and over 95% of pharmaceuticals like ibuprophen and Bisphenol-A. It removes over 99% of the tested varieties of lead, and over 97% of chlorine.
Do you need an activated carbon water filter?
You have a few options, if this is the type of filter you want. An under sink filter, and a filter jug are your other options. A tap filter, though, is one of the simplest and most convenient options.
Here’s where you can check out your best options for an activated carbon filter.
FYI, if Fluoride is a concern of yours, here are the top Fluoride water filters. And what about filters to remove hormones? Got that covered, too.

Best Water Filter For Tap UK Summary
