We’ve been around for a while, in the area of water softeners and water filters, in general.
Ten to fifteen years ago, it was something of an arms race as hard water shower filter makers raced to add more stages to their filters.
We remember seeing 5-stage filters, and thinking “ooh, not bad”. Then came 8-stage, then 10-stage, then 20-stage… and so on. I think we were at 1,375-stage last time we checked. 😉
Anyway, this war of attrition couldn’t last. And the increasing number of stages was adding just very slight iterative improvements.
In the last 5 years, however, has seen the advent of some genuinely new technology for removing hard metals, and also for reducing the impact of the metals in the water on your skin and hair.
So in this review, we’ll be discussing and analysing those new technologies and how well they are implemented in the various water filter options you have available.
We evaluated both shower head filters and in-line filters.
To that end, we looked at:
- Ability to mitigate or remove hard water problems
- Effectiveness at filtering other harmful contaminants that people want to avoid
- Ease of installation
- Filter cartridge replacement frequency
- Ease of filter cartridge replacement
- Value for money – for the original filter purchase and the replacement
We’ll also rate the various models for their ability to meet different use cases. So you can be sure to get the right model for your specific needs.

Hello Klean Shower Filter
Plus points and who needs this:
The most effective performer at reducing skin and hair problems
Most mid to high-level hard water shower filters can mitigate skin and hair problems. Not that many have an extremely high percentage success rate. They work in some cases and not in others. After canvassing users, distributors, and professional customers in the industry, we discovered that the Hello Klean filter has a very high rate of success. This was backed by consumer perception trials conducted by Hello Klean, with nearly 90% of users noticing softer skin and hair. The most impressive part is the Klean Complex, which is a major step beyond even high quality activated carbon filters. And it is certainly far beyond the countless beads and resins (like ceramic balls, anion balls, calcium sulfite, negative ion balls and so on) which make up the majority of those of the 15 to 20-stage filters we mentioned in our introduction. Klean Complex is able to successfully mitigate the impact of metals on your skin and hair by changing their composition, even if not removing them entirely, as whole house water softeners do.
All materials used are high quality
It’s definitely in the higher price bracket. But it’s pretty easy to see that the materials are much higher end than most shower filter products. The pictures present it as such, and as soon as you open the packaging and touch the various parts, that initial sense is confirmed.
Attention to detail is impressive
What do we mean by attention to detail? We mean that Hello Klean have clearly spent a lot of time and effort on making sure installation is as easy as possible for the average person to do. For example, the container is softer and thinner, made with a soft silicon, making it easier to install and manoeuvre into the right position. The instructions are extremely simple and clear. There’s handy tape to ensure a tight seal. It comes with surprisingly decent tools to help you install. Overall, the quality and attention to detail of everything down to the packaging are impressive.
Cons and why this model may not be for you:
It’s expensive
That is, both the original product cost and the ongoing cost of replacement filters. Check the bottom of this review to find some cost vs. benefit considerations to help your buying decision.
Not as effective as a whole house water softener
We’ve talked glowingly about the Hello Klean model’s effectiveness at reducing hard water problems. But let’s be clear: the optimal solution is still a whole house water softener, which is the only way to actually remove calcium and magnesium (the metals that are most responsible for the various negative effects of hard water.
Showery Halo Premium
Pros and who needs this:
Highly effective filtering technology
The filters used in Showery’s premium range are at the top end of activated carbon filtration. It’s highly effective at removing heavy metals, chlorine and other contaminants. Scientific journals (like this one) have shown activated carbon to be the best at removing natural organic matter, among many other impurities.
The makers are shower specialists and a British company
Showery are a British company that specialise in shower products. That means more accountability, more contactability in the event of any problems with your purchase, especially when compared to buying on online marketplaces. As you may expect with a company which has shower products as their sole focus, the attention to detail with all aspects of the product is great. The shell is made of high-quality chrome, and Teflon tape is effective for ensuring a tight seal.
Good eco-credentials
Showery filters last longer than other similar options, as long as 6 months. They encourage you to send used filters back for recycling. Packaging is recyclable. And finally, Showery partners with OneTreePlanted – meaning they plant a tree for every purchase you make.
The luxurious choice
The ability to alleviate problems caused by hard water is certainly the No.1 product requirement, let’s be clear about that. The Showery shower head delivers on that, and then offers a luxury addition, if you want it. That is a brush and sponge, so you can turn your shower into a self-massage experience.
Cons and why this model is not for you:
Effective but still less outstanding filtration results than the Hello Klean shower filter
It also has garnered highly impressive results for many people, improving their skin and hair, significantly lessening the problems they were having due to hard water. But we evaluate the Hello Klean model even higher in this regard.
It’s also pretty expensive
This is the shower head filter that combines impressive contamination removal with luxury add-ons. That comes at a fairly hefty cost.
Expert Tip
Cost vs Benefit
Are you trying to decide which model to buy?
Here are the key evaluations to make:
What are the issues I face?
How significant are the problems caused by showering with hard water, for you?
So tot up the costs of the shower filter that sounds right for you.
Work out the cost of the filter itself, and then calculate the yearly costs for replacing the filter media.
Look at that yearly cost, let’s say it’s £60, purely as an example.
Then, consider the issues I face, let’s say it’s drier, less smooth hair, and some skin sensitivity issues.
Would I pay £60 a year to fix that problem?
This is the cost vs benefit question that will provide you with your answer.
If the answer, is no, it’s not quite worth that cost, then check out the lower cost model.
Anything else we should know?
You may be pondering the likely amount of time a filter will last you, and how often you’ll have to replace the filter media.
Well-made filters like the winners in this article don’t suffer from some issues that plague lower quality models.
The shower head/filter should last at least 5 years and perhaps longer.
As for the frequency of filter replacements required, it really depends on how hard your water is. And of course how many showers you take in a given month!
You could estimate that someone with very hard water, with a large household full of people that take showers all the time, you may get as little as 2-3 months.
If your hard water is not that severe, and the shower is used only once or twice per day, it could be as long as 5-6 months before you need to replace it.
Do your hard water issues extend beyond the types discussed here? If so, then you may need a fully fledged whole-house water softener. Here is a comparison of salt-free and salt-based softeners.
