Benefits of a Whole House Filter System

If you are thinking about installing a water filter in your home, then you have a decision to make between using one or more Point of Use Filters (POU) or going with a Point of Entry (POE) Whole House system that provides clean, filtered water to your entire household. 

If drinking water is the only thing on your mind, then an under sink or countertop filter is a perfectly acceptable solution. These filters are specialists at reducing unwanted contaminants from your water that leave it perfect for ingesting into the human body, with minimal fuss and footprint in terms of installation. 

But what if you don’t want to stop at drinking water? What if you want beautifully clean water in your showers, baths, and dishwashers? This is where a whole house filter system becomes the prime candidate for your situation. 

Benefits of a Whole House System 

  • Wide variety of filter types – specialist filter cartridges are available that can be used to combat specific, difficult to remove contaminants 
  • Wide spectrum of contaminants removed – this includes VOCs, chlorine, cysts, bacteria, pesticides, herbicides, and heavy metals such as lead 
  • A single filter for the whole household – one point of installation and maintenance saves time and money in the long term 
  • Variable flow rate – different systems operate at different capacities, allowing the flow rate to be customised to fit your situation 
  • Reduced limescale – many of the filters available in whole house systems help to reduce scaling build up, increasing the longevity of household appliances 
  • Adaptability – the standard size of the cartridge housing allows for various specialist filters to be used when necessary, meaning that your filter system can be adapted to suit whatever circumstances arise 

Cost vs Benefits 

What represents the largest barrier to entry for a whole house system is the initial cost of purchase and installation. These units can seem like an expensive alternative to POU filters at a glance, however when you weigh up the long-term benefits of a whole house system then the bigger picture starts to become a lot more palatable. With a whole house system, you’re investing in clean water for your whole household in a way that is efficient, easier to maintain, and adaptable to whatever water situation is thrown your way.  

Choosing a Whole House System 

The first step to finding the right whole house system for your household is to get your water tested. A simple home water test kit will be able to give you an accurate indication of which contaminants are present in your water, along with the water’s pH value and hardness. The properties of your water will determine which system and filters you’ll need to get the most out of your new setup.  

The second important step you need to take before diving into a purchase is to understand your required flow rate. A higher household flow rate requires a larger capacity system, but the larger the capacity the more expensive the system. For this reason, you don’t want to be paying for a larger system than you need, but equally you need to ensure the system isn’t too small that it can’t keep up.  

Whole House Filter Options 

  • Chlorine, taste and odour filters – One of the main concerns when it comes to water in your household is chlorine. Alongside the fact that nobody wants to feel like they’re drinking a swimming pool, there are also health implications associated with sustained chlorine ingestion over a long period of time. Chlorine filters typically use a carbon block or granular activated carbon (GAC) solution, which achieve an impressive chlorine removal rate of around 99.99%. 
  • Sediment only filters – these filters are useful when your water is having issues relating to sediment and particulates. These issues can arise as a result of sediment building up in the water mains over time, and that sediment then being disturbed by a number of issues including construction, loss of pressure, opening and closing valves and more. These filters are graded in microns, a unit a measurement that determines what size of particulate the filter will remove. 
  • Multi-housing filter system – when you want to tackle the widest range of contaminants possible, a multi-housing solution is the solution. These systems allow you to implement multiple specialist filters, each of which can be responsible for taking care of their own contaminants.  

Caring for Your Whole House Water Filter System 

Even the best and brightest water filter system will become useless if you don’t give it the correct care and attention it deserves. Luckily for you, this care and attention just comes in the form of a simple filter change from time to time. 

The time between filter changes can depend on variables such as the type of filter, the volume of water that has passed through, the level of contaminants it has had to filter, water hardness, and more. For this reason, filters come with a recommended lifespan, usually around 6 months depending on the type of filter, and if you make sure to stick to that timeframe then you won’t have to worry about performing the mental gymnastics of all those variables.  

If you want to squeeze every drop of filtration potential from your system then you can supplement it with addons such as a water meter, which will keep track of the exact volume of water that has passed through. Additions such as these can give you greater insight into how much work your filters have put in over a period of time that you can then use to calculate more accurate timeframes for filter changes. 

Should You Buy a Whole House Water Filter System? 

Whilst these whole house systems can be an intimidating and significant investment, they offer a complete solution for your entire household in a much more efficient and timely manner than individual POU filters. If you want a multi-room solution that can tackle multiple different contaminants, then nothing will accomplish that task like a whole house system. You can’t put a price on the long-term health benefits and peace of mind that comes with knowing your home’s water is clean, healthy and safe.
