What Water Filter Removes the Most Contaminants

Considering what the healthiest water filtration system is, requires an understanding of not only how filters work and what contaminants they can remove, but also the impact your chosen system makes on the environment. As suppliers of instant water filtration systems for over 25 years, Billi are the water filtration experts in Australia. Keep reading to learn more about our premium filters.

 

Which Water Filter Removes the Most Contaminants?

Generally, the smaller the micron number the more contaminants a filter can remove. For example:

  • A 5 micron filter can remove particles visible to the naked eye.
  • A 1 micron filter will remove particles which you can’t see

 

However, neither of these will reduce heavy metals, or parasitic cysts, giardia and cryptosporidium. For that you need a 0.2 micron filter.

 

What is the Healthiest Water Filtration System from an Environmental Perspective?

The healthiest system for the environment eliminates the use of plastic bottles and reduces energy usage. As such an on-tap, under-sink system is best. Additionally, Billi’s unique energy reclaim system boasts eco-credentials in that it recovers waste heat energy generated by chilling water.

 

Which Water Filter Removes the Most Chlorine?

Our premium 0.2 micron filter can reduce chemicals such as chlorine and other heavy metals.

 

What Kind of Water Filter Removes Bacteria?

Again, the smaller the micron filtration the better. Our premium micron 0.2 filter can remove parasitic cysts, giardia and cryptosporidium.
