How to Evaluate the Sustainability of a Water Filtration Unit

There are different water filtration systems and technologies on the market but when considering sustainability, there are a few factors you need to check. This is because not every filtration system will be the same when it comes to sustainability.

You need to check

The energy efficiency of the filtration unit as this will give you a good idea of its sustainability. There will be some systems that will need more energy to operate and these will consume a higher level of electricity. This will therefore have a larger environmental impact. You can visit to get an idea of the efficiency of the systems available. There are a few factors that will help you consider the level of energy efficiency. There will be an energy star certification given to the filtration system. Systems with this certification will be adhering to strict energy efficiency standards. This will ensure that the environmental footprint of the filtration system is reduced. Consider the power source for the filtration unit. There are gravity-driven processes and hydraulic processes; these will be more energy efficient compared to electrically powered units. You can also select a unit that uses only a minimal amount of electricity. The other option is to look for a filtration system that can be powered by renewable energy.

Consider the mode of operation for the filtration unit.

Some filtration systems will come with automatic features that will help optimise the use of water. There are energy saving modes in some systems so that energy consumption can be reduced when it is not in use. The water efficiency of the filtration system has to be considered as well. If the unit is using an excessive amount of water for filtration, this may not be ideal. Consider the ratio of filtered water to wastewater. There are some filtration systems that produce wastewater. One example is reverse osmosis systems. You can choose units where the waste wastewater quantity is reduced. If the filtration technology is faster, this will use less water during the operation; however this feature should not compromise on quality of water. You need to look for a system that balances quality of water with a high flow rate.


Consider the materials used for the construction of the filtration system.

There should be a reduced amount of non-renewable items. You can look for units where the components have been made from sustainable or recyclable materials. Some materials you can look for are stainless steel and BPA free plastic. You can also consider the manufacturing practices to check whether these prioritise environmental responsibility. Long term durability is another factor to consider as you will not need to replace the filtration system often. This will depend on the build quality of the unit. Make sure to check the warranty provided by the manufacturer and whether there is repair or servicing options provided to extend the life of the filtration system. When there is a longer warranty, there is some assurance about the quality of the system and its durability.
