Understanding Water Filters in Spain: A Comprehensive Guide

If you’ve ever contemplated buying a water filter and searched for options in Spain, you’ve likely encountered numerous companies promising crystal-clear, pure, and safe drinking water. However, the reality is that there is no one-size-fits-all water filter solution. The quality of drinking water in Spain varies significantly, especially in regions like Almeria, known for its hard water, intensive agriculture, and highly mineralized rocks. Even houses next door to each other can receive water from different sources and of different quality. This is why, at Almeria Pure Water, we always start with a professional water quality test before recommending any filtration system.

What Is In Your Water?

If you are on mains water, there’s a common assumption that all the water is the same. In Spain, this is far from true. Different municipalities source their water from various locations, creating a unique blend of contaminants, minerals, and treatment residues.

Our 24-point water test uses official Spanish government criteria to understand exactly what is in your water—from Total Dissolved Solids (TDS) and pH levels to less obvious contaminants like nitrates, pesticides, and metals.

Unfortunately, many other companies rely solely on TDS tests, performed with a basic electrode tester, to assess water quality. This method measures everything that is not water, providing a level of Total Dissolved Solids (TDS) in Parts Per Million (ppm). When used alone, this test can be misleading. For instance, Glyphosate, a common ingredient in weed killers, does not show up in TDS tests because it’s non-conductive.

While TDS is useful information, it’s only one part of a household’s overall water quality picture. It fails to capture non-conductive contaminants that may pose health risks to you and your family. That’s why we measure multiple parameters before making any recommendations.

All Filters Are Not Created Equal

There are many budget water filters available for sale online, in local shops, and even market stalls. However, most are not up to the job. The worst part is that there are often no visible red flags indicating that they are ineffective. This can lead to households consuming contaminated water while believing it is pure and safe.

One of the most popular Reverse Osmosis systems sold online in Spain is only rated for water with a TDS of 750 parts per million. This is inadequate if your water tests at 1,000 ppm or higher—a common scenario among our customers.

Our standard range of Reverse Osmosis water filters is tested to handle up to 1,500 ppm TDS. We even have machines capable of processing water up to 2,000 ppm TDS, making them suitable for highly contaminated water scenarios.

The Practicalities of Plumbing

Another challenge to the ‘one-size-fits-all' water filtration solution concept is the condition of your plumbing system. Spanish houses vary greatly in terms of pipework quality, fittings, and accessibility. Some homes have pipes buried deep behind walls or tiled surfaces, making filter installation extremely challenging without invasive work that may quickly become financially impractical.

Before recommending any water filter product, we assess whether your system is suitable for installation. We ensure that the correct, highest quality fittings are used. Believe it or not, in some cases, we advise against installation altogether due to poor accessibility or degraded plumbing.

How Would You Like to Access Your Filtered Water?

One important consideration before recommending a water filtration system is how you prefer to dispense your filtered water. We offer a range of solutions, from standalone filtered water taps to elegant three-way taps that combine hot, cold, and filtered water in one unit.

Your preferred method of accessing filtered water usually impacts the installation. For instance, will a new hole be needed in your kitchen counter? Is there enough space under your sink for a unit? These are just a few of the many considerations we assess during a site survey.

Beware of Quick-Fix Installations

One popular budget solution is a filter that installs directly onto the kitchen’s cold-water line. This may seem convenient at first, but it often leads to customer dissatisfaction. Why? Because these low-flow cartridge filter solutions only deliver around 2 liters of water per minute—far below average daily use. Additionally, users are forced to use filtered water for tasks that don’t require it, such as washing hands or filling a bucket to wash the kitchen floor.

Moreover, filters with small capacities (e.g., 8,000 liters) will need replacing multiple times a year if used on your main tap. This cost adds up quickly. Our systems come with dedicated drinking water taps as standard, allowing you to use filtered water only when necessary, saving money and reducing waste.

Test Before You Invest

Bad-tasting tap water in Spain doesn’t always mean the water is unsafe. However, it does mean that you should never guess what filter to install.

A professional water test allows us to recommend the right water filtration system for your home based on actual data—not guesswork.
