Dealing with the problems of hard water can be a real headache. Especially when there are several different and interchangeable names for systems on the market. So what is a hard water filter? Do these systems even exist? If not, then why is the term used? In this article we’ll answer all the above and clarify what the devices on the market are that you’ll want to research when looking for a solution to your limescale issues.
Water Filters
The concept of water filters is fairly straightforward, they are designed to filter out additives and impurities in the water. In theory then hard water filters should exist? This is both right and wrong, most water filters do not filter out hardness. Instead, filters tend to remove things such as chlorine from the water. There are filter that can remove hard water minerals from the system, the most used being reverse osmosis systems. However it is important to note that running these filters is very costly, as such they aren’t often used to treat the whole house. So specialised hard water filters aren’t what you should be looking for when trying to treat your hard water. So what should you be searching for?

Water Softeners
Water softeners are currently the most well know devices used for treating limescale. In short water softeners use a process called ion exchange to remove the hard water minerals from the water using a process known as ion exchange. Salt is a key part of this process which is why these systems are sometimes called salt softeners. Water softeners do just what they say on the tin, they provide the household with soft water. However, there are several downsides with this method. Water softeners take up a lot of space, have ongoing running costs, require regular upkeep and maintenance and aren’t very environmentally friendly.
Water Conditioners
The other option is the lesser-known water conditioners which come in several different shapes and sizes. Conditioners deal with limescale by targeting the hard water minerals and changing the way they behave rather than removing them. This results in water that is still hard, but that doesn’t build up scale inside appliances and on surfaces. Instead, you can expect a fine easy to clean residue on these surfaces instead. Because Water conditioners are quite diverse and use different methodologies they can vary in quality and in the benefits they can bring.
Final Thoughts:
So what is a hard water filter? There are several different devices which deal with the issue in different ways. But for the most part there is no such thing as a specialised water filter and you should be looking into water softeners or water conditioners to deal with your limescale problems.
