How much do water filter systems cost?
The cost of water treatment systems varies widely depending on the type, capacity and features. Basic jug or countertop filters start from a more affordable price point, while under-sink and whole-house systems can be more of an investment due to their larger size and more advanced filtration technology. When deciding on a tap water filter system, it’s important to also consider the long-term costs of replacement filters and maintenance. At the same time, remember to factor in the potential cost savings. Plenty of offices and households drinking store-bought water find installing a filter system actually saves money overall! Some people showering in or drinking unfiltered tap water may also find many of their health concerns disappear, saving them from unnecessary medical bills.
How long does a water filter system last?
The lifespan of a water filter system depends on various factors, including the type of system, the quality of the water being filtered, as well as how much water is being used daily. Generally, smaller water filtering systems like jug filters need to be replaced more often, like every few months, while larger systems like whole-house filters can last many years before requiring replacement.
How often do you need to change a water filter?
The frequency of changing a water filter will ultimately depend on a few elements. The type of filter will make a major difference as different types of filters have varying lifespans. Activated carbon filters, for example, typically last somewhere between 2 - 6 months while reverse osmosis membranes can last 1 - 2 years. It’s important to note that the more water you use, the faster the filter will become saturated and need replacement. Similarly, water quality can also contribute to the frequency of water filter replacement. If your water source is contaminated or has high levels of sediment, chemicals or other pollutants, you may need to change the filter more frequently. As always, it’s recommended that you follow the guidelines provided by the manufacturer of your specific water filter system for optimal performance and replacement schedules. Regular maintenance helps to ensure that your water remains clean and safe to drink.
How does a water filter system work?
Water filter systems work by passing water through one or more stages of filtration media which traps contaminants. Types of media can include activated carbon, which removes chemicals like chlorine and compounds that cause taste and odour issues; ion-exchange resins, which can soften water and remove contaminants like lead; and mechanical filters, which physically remove sediment like dirt, rust, sand and microplastics. More advanced water treatment systems may also use technologies like reverse osmosis or UV purification for even greater purity.
What are the types of water filter systems?

There are numerous types of water filtering systems, each suited to different needs:

  • Jug Filters: Simple and convenient, jug filters are ideal for individuals or small families looking for a portable water filtration system. They are best suited for filtering drinking water in small quantities and are a cost-effective option for those seeking a basic level of water purification.
  • Faucet-Mounted Filters: This type of tap water filter system offers the convenience of filtered water straight from your tap, making it ideal for cooking and drinking water needs. Faucet-mounted water filtering systems are easy to install, attaching directly to your faucet, and allow you to switch between filtered and unfiltered water.
  • Under-Sink Filters: Installed out of sight under the sink, these systems provide a higher filtration capacity compared to jug or faucet-mounted filters. Often installed along with Whole-House filters, these systems typically offer a finer level of filtration, perfect for high-purity drinking water. They are connected to your water line, providing continuous access to purified water. 
  • Countertop Filters: These water treatment systems strike a balance between ease of installation and filtration efficiency. They sit on the counter and connect to the faucet with a tube, making them a great choice for renters or those who prefer a non-permanent filtration system.
  • Whole-House Filters: As the most comprehensive option, whole-house filters are installed at the main water entry point to the home, ensuring that every drop of water used – whether for drinking, cooking, bathing, or laundry – is filtered. This water treatment system is ideal for households concerned about contaminants affecting not just drinking water but also water used in showers, washing machines, and more.
  • Reverse Osmosis Water Filter: Known for providing an extremely high level of filtration, reverse osmosis systems are capable of removing a wide array of contaminants, including dissolved salts and impurities. These water filtering systems are typically installed under the sink and are ideal for households seeking the highest quality of water purification for drinking and cooking.
  • Ultra Violet (UV) Water Filters: Utilising ultraviolet light, these systems are designed to kill bacteria and viruses, ensuring the microbiological safety of the water. Often used in conjunction with other types of filters, UV disinfection systems are well-suited for areas where the microbiological contamination of water is a significant concern.
  • Water Softeners: Water softeners are specialised filtration systems designed to remove or reduce the concentration of minerals, particularly calcium and magnesium ions, from hard water. They work by exchanging calcium and magnesium ions with sodium or potassium ions through a process called ion exchange.
