Water is a pure product that is contaminated by natural and man-made chemicals. These chemicals can be eliminated by careful and progressive filtration to revive the pure product. Although some chemicals are essential for health and wellbeing, we believe eliminating unwanted contaminants through selective filtration gives a desirable and refreshing product essential for our survival.
Many factors affect the flow rate of water: the size of pipe, the mains pressure and the quality of source water going through the filtration media, to name a few. Flow rate will also depend on the system installed, whether you are filtering just for drinking water or for the whole house. Drinking water via a filtration system will flow at a slightly slower rate than unfiltered water because the filter media restricts the flow. This restriction is to help the filter trap unwanted contaminants. The slower flow rate allows the water more time to meet the filter, thus optimising the treatment.
Reasons to change the filters will depend on three factors: quality of your filter, volume of use and quality of your source water. The change times of our best-quality filters will depend on how water your household is consumed and the type of water to be treated. Typically, cartridges need to be changed between six to 12 months.
It’s essential that your water be tested prior to purchasing the water filtration system because water quality can differ from home to home. When we get the report, our experts will analyse and recommend the type of water filtration system required, according to your need.
Under Sink Filter FAQs
Standard under-sink filters will not remove fluoride from the water. We recommend using reverse osmosis, the safest, and most effective way of removing fluoride. There are proclaimed Fluoride Removal Cartridges on the market, however they use a material called Activated Alumina which will remove up to approximately 80% of fluoride while the filter is new, but is known to then rapidly depreciate to the point where it is no longer effective. The other downside to the Activated Alumina cartridges is that they have a tendency to leach heavy metals into the water when the filter ages. If you do not keep a strict routine for filter replacement, it may be introducing dangerous heavy metals into your drinking water.
There are a few different models of under-sink filters that each have their own specific purpose. The most common model is a Sediment + Coconut Carbon configuration. As the name suggests, it has a dual action, the first filter will remove dirt/particles and sediment, while the Coconut Carbon filter absorbs chemicals such as chlorine. Some systems elect to use a Dual Coconut Carbon Set up to double the contact time with the water. Carbon efficiency is largely influenced by contact time, so adding more carbon to a system can greatly increase its ability to remove hazardous chemicals, tannins, tastes and odours.
Under-sink water filter cartridges should be changed anywhere between 6 to 12 months. You will usually notice a distinct change in taste of the water if you have the filters in too long. This signifies that the Coconut Carbon Cartridge is no longer working to its full capacity and is beginning to allow residual amounts of chemicals through into your drinking water. As a rule, you should not leave your filters in for longer than 12 months, regardless of if you are on town or rainwater.
