Filtration Capabilities

The AQ-4105C uses a 2-stage filtration method to remove contaminants from shower water. The first layer is made up of a blend of Zinc and Copper and is known as KDF 55 Process Media. It reduces Chlorine levels and helps to balance and enhance the water's pH. The second layer consists of Centaur Carbon Media, which, like the first layer, heavily reduces Chlorine levels and removes Chloramine alongside a variety of synthetic compounds. Between these layers, the AQ-4125C filter used in the AQ-4105C system meets the NSF Certified Standards 42 and 61 and is able to reduce Chlorine levels by over 90%.

Healthier Skin & Hair

Chlorine may be a good way of keeping bacteria levels low, but unfortunately, it can lead to dry, flaky skin and straw-like, flat hair by stripping away natural protective oils. Therefore, by reducing Chlorine and Chloramine levels by over 90% with the AQ-4105C you can re-energise and revitalise both your skin and hair, keeping them hydrated for longer for smoother and softer results.

The filtration offered by the AQ-4105C also enhances hair and body washing products such as shampoos, conditioners and lotions by allowing them to lather with greater ease. This allows for less product to be used each time, saving money and time every day.

Finally, it can also heavily reduce the levels of many different synthetic compounds and VOC's (volatile organic compounds). These chemicals can vaporise in hot water, allowing them to be inhaled or absorbed through the skin, potentially causing adverse health and cosmetic effects.

Installation Method

The AQ-4105C has been built for easy installation and it can be put together quickly without the need for professional help. It has been designed to attach to any existing shower pipe with a 0.5 inch (1.27 cm) diameter and it screws on easily over the top with a strong watertight connection.

Common Questions

Do I have to pay for a plumber to install the system?

The AQ-4105C is very easy to install, and you can do it yourself in minutes, so a plumber is not often necessary. If you have any questions or need assistance, our technical support representatives can walk you through the installation process by phone.

Which replacement filter do I need to use in the AQ-4100C?

The correct replacement filter for the AQ-4100C is the AQ-4125C Shower Replacement Filter. It is provided as a single cartridge that can be replaced with minimal effort.

Will the AQ-4105C be compatible with my shower?

A typical shower connection pipe will have a 0.5 inch (1.27 cm) diameter and the AQ-4105C has been designed to work with fittings of that size. Therefore, to confirm its compatibility you will need to measure the diameter of your shower pipe.

If the pipe isn't 0.5 inches in diameter it will still be possible to connect the AQ-4105C, but you will need a step-down or step-up adaptor. These can be purchased in most hardware stores and easily screw over the current pipe's thread. Although don't forget to use plumbers tape when using an adaptor for a watertight connection.

Can I use my own shower head or hand-held wand?

It is possible to connect a different showerhead or wand to the AQ-4105C, but it is not recommended. Any new attachment that is connected should have a 0.5 inch (1.27 cm) diameter to connect to the filter and it should ideally work at the same flow rate of 2.5 gallons per minute.

If the flow rate exceeds this, the filter may degrade and be less effective in removing contaminants as a result of reduced contact time with the filtration media. A flow rate that is too low can also lead to damage in the filter and any damage caused to the system where a custom showerhead or wand is in use can void the warranty.

How do I know how many showers it takes to use 10,000 gallons?

When connected to a water supply with a flow rate in the allowed parameters the AQ-4105C will typically use 2.5 gallons per minute. This equates to around 4,000 minutes of showering for its full 10,000-gallon lifespan.

Can I use the AQ-4105C for drinking water?

Drinking some of the water during your shower poses no risk. However, it is not recommended that you use the AQ-4105C as a primary drinking water source since it is not designed as a drinking system and has only been tested and certified under shower conditions and regulations.

Can I connect the AQ-4105C under a constant pressure application?

No, the AQ-4105C is designed to allow water to consistently pass through the system as it filters. If the system is under constant pressure and unable to release, the pressure introduced into the system during filtration can cause damage to occur to the unit or the filtration media.
