Single Undersink Carbon Water Filter System (GT1-15WM)

Enjoy cleaner, fresher-tasting water straight from your tap with this premium Undersink Water Filter Kit from High Performance Filtration (HPF). Featuring a WaterMark certified housing and a top-tier 1 micron 100% Coconut Carbon Block Filter, this compact system is ideal for reducing chlorine, taste, odour, and other common town water impurities.

The included 1 micron coconut carbon filter is made entirely from activated coconut shell carbon—renowned for its high adsorption capacity, longer service life, and superior ability to improve taste and odour. Unlike many cheaper filters on the market that use a coal-blend media, this is a 100% pure coconut carbon block, delivering high-performance filtration with low pressure drop.

Perfect for households on mains water supply, this undersink kit is easy to install, compact, and comes with everything you need for a standard setup—including a WaterMark approved pressure limiting valve and dedicated drinking water faucet. It’s the ideal solution for homes seeking a reliable, cost-effective drinking water system without compromise.

Will Undersink Water Filters Remove Fluoride?
Standard Undersink filters will not remove fluoride from the water, we recommend using reverse osmosis as it is the safest, and most effective way of removing Fluoride from the water. There are proclaimed Fluoride Removal Cartridges on the market however they use a material called Activated Alumina which will remove Fluoride up to approx. 80% while the filter is new, but will then rapidly depreciate to the point where it is no longer effective. The other down side to the Activated Alumina cartridges is, 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.

What are Undersink filters for?
There are a few different models of Undersink filter that each have their own specific purpose. The most common model of Undersink filter you will come across is a Sediment + Coconut Carbon configuration. As the name suggests, they have a dual action, the first filter will remove dirt/particles and sediment, while the Coconut Carbon filter absorbs chemicals from the water such as Chlorine.
Some systems elect to use a Dual Coconut Carbon Set up to double the contact time with the water. As we know that carbon efficiency is majorly to do with Contact Time adding more carbon to a system can greatly increase its ability to remove hazardous chemicals, Tannins, Tastes and odours.

Can an Undersink Water Filter remove Chloramine?
Chloramine Injection has recently been introduced into many council regions over Australia, including on the Gold Coast where FSA is based. Chloramine presents a number of issues in regards to drinking water including but not limited to; dissolving of heavy metals such as lead into the water, release of ammonia gas and adverse skin reactions. As previously mentioned, the more carbon the better. Chloramine is very hard to remove by normal means and it is removed in 2 staged. The first carbon filter acts to break open the Chloramine which in turn, releases the other various residual gasses into the water, the second carbon can then easily extract and absorb all remaining residuals, effectively removing the dangerous Chloramine from your drinking water.

How often should I change the filter cartridges?
Undersink Water Filter Cartridges should be changed anywhere between 6-12 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 if you are on town OR rain water.

What is filter protection equipment, and do I need to use it?
 Filter Protection Equipment is an important part of water filtration. Our products are sourced from experienced and reliable manufacturers and also carry the highest level of certification in the water filtration industry. Regardless of Brand, Make, Model or Country of manufacture, water filtration will ALWAYS be the weakest point in your plumbing. The three main causes of water filtration failure are; Overnight pressure surges, Intense Water Hammer Pressure Impacts, and thermal expansion. All of which can be addressed and prevented with a few simple pieces of equipment. A Pressure Limiting Valve is used to buffer the incoming pressure to the Australian Regulation Pressure of 500kPA. This is the minimum requirement for most insurance and warranty validation and is essential when used on Town mains / municipal water. A Water Hammer Arrestor is a copper tube looking device which is commonly found in the laundry (If you have one). It acts to absorb and dissipate pressure spikes in your water lines. Pressure spikes occur from appliances such as the washing machine or dishwasher and can magnify the water pressure tenfold which can cause serious damage to water filtration components. Water hammer gets the name by the distinct sound you hear when the shockwaves rattle loose copper pipes or worn out valves. This is something that is essential to be addressed immediately before installing water filtration. A Pressure Relief Valve is as it sounds. It is pre-set to open once the pressure reaches 110PSI, shooting that pressure/water down the drain line and easing the pressure in your water filter. This is a requirement if you intend to hook up your water filter to a fridge, chiller or ice maker. They are also a good idea to help relieve residual pressure from pressure surges (even if you have a PLV + water hammer arrestor).
