Types of Water Filters

There are many different types of water filters on the market, all with their features and benefits. It can be hard to know what type of water filtration system will be best for you so below is info on what factors to consider when it comes to the different types of water filtration solutions.

For over 30 years Billi has been at the forefront of the instant filtered boiling and chilled water systems industry. Our products are celebrated for their combination of functionality, performance and contemporary aesthetics. All our systems are proudly Australian-made and designed in our state-of-the-art facilities in Melbourne and are used here in Australia and around the world. Here is what to consider when choosing what type of water filtration system to go with for your home:

 

What To Consider When Looking At Different Types Of Filtration Systems

There is quite a variety when it comes to the different types of filtration systems – from large whole house filtration systems to compact, specialised systems designed to filter drinking water only. And with these systems, there are some significant differences when it comes to budget, space, access to electricity & water, support and maintenance costs.

If you’re considering types of water filtration that filter your whole house’s water supply, bear in mind that installation may require your plumbing to be reconfigured to accommodate the complex parts of the system. The benefit of having whole house water filtration systems is that they filter the water for your entire home’s plumbing and appliance. However, they generally only have a 30 to 50-micron filter as they need to be able to still allow normal flow of water through. This means the filters may not filter out everything you want to be removed from your water. If you’re looking for high-quality drinking water, then an under bench system may be the way to go.

 

Under Bench Water Filtration Systems

Under bench systems are specialised filtration systems designed specifically to filter drinking water only. With these systems it is possible to have up to a 0.2-micron filter which provides the highest level of filtration for drinking water – however, they don’t protect your entire home’s plumbing and appliances. Often, this is why people choose to have two types of water filtration – whole house filtration to protect their plumbing & appliances along with filtration specifically for their drinking water.

Most types of water filtration will also require ongoing filter replacement to maintain the quality of the filtered water and to ensure the system operates effectively over time. Whole house water filter systems have the biggest cartridges because they need to treat a larger volume of water daily without reducing the flow rate and may also require a professional to replace them.

Under bench systems have a smaller filter so upfront or ongoing costs may be more affordable, however, they may need to be replaced more frequently (we recommend replacing our filters every 12 months). Under bench filters can usually be installed by yourself. We have videos that show you how to replace the filters for our systems but we can also arrange a technician to change filters for you if preferred.

Ensure filter cartridges are easily available and also check what water filter cartridge types are compatible too. Genuine replacement Billi filters are available on our website or from your local approved supplier.

 

 

Water Filter Types

We have a range of water filter cartridge types available for our systems so you can choose the filtration level that best suits your needs. Our 0.2 Micron filter reduces the following from your water:

  • Sediment / particles
  • Chlorine and organic chemicals
  • Limescale
  • Parasitic cysts including cryptosporidium & giardia
  • Lead and heavy metals

 

Our 5-micron filter provides a more standard option to improve drinking water and reduces the following:

  • Sediment / particles
  • Chlorine and organic chemicals
  • Limescale

 

Other Benefits and Considerations

Another benefit of having an under bench system is that, like the systems in our range you have the convenience of instant boiling, chilled, still and sparkling water on tap. This means fewer kitchen appliances are required (no more kettle or manual sparkling water machines!), you no longer have bottles of chilled water taking up space in the fridge and they’re great for those who like to entertain. We also have systems in our range that feature our unique Heat Exchange Technology which enables them to achieve substantial energy savings making them energy efficient.

When it comes to installation, under bench systems are installed in your kitchen cabinet so they don’t take up bench space and they’re tucked away out of sight (our systems have one of the smallest footprints on the market so they don’t take up a lot of cabinet space either). We have an extensive range of models that do not require cupboard ventilation cutouts or grilles so they are quick, easy and cost-effective to install too.
