Our most common questions about Kitchen Water Filters

Our systems connects to a wall outlet like other electrical appliances. The systems should always be connected to a dedicated wall outlet protected by a GFI (ground fault interrupter) /RCD. In areas that experience significant power fluctuation, we recommend the use of a surge protector.

A UV-lamp has a lifetime of 365 days of continuous use. After that, the UV-light intensity starts to diminish and it is no longer able to effectively disinfect the water. It is very important to replace the UV-lamp every 365 days to ensure that your water is still safe to drink. Our Whole Home Systems have a sophisticated control unit that will let you know the status of the system. It tells you how many days are left until lamp replacement and will give you a visual and audible alarm when the the lamp life is due to replacement.

UV lamps have a useful life of about 9000 hours (approximately 365 days) which means that in most cases annual replacement is required. It is very important to replace the UV-lamp after 9000 hours, since there may not be enough UV energy to provide adequate disinfection after that.

There is also a quartz sleeve that surrounds the UV lamp which must be kept free from hardness or iron deposits that would have a negative impact on the UV disinfection process. Under normal conditions the sleeve can be cleaned when doing the annual lamp replacement.

For our Whole House and Point of Use Systems that comes complete with pre-filters (sediment and carbon) maintenance includes replacing these when they get dirty or clogged. Replacement interval for pre-filters depends on usage and water quality in your local area and can vary from between 5-12 months.

No, not at all. Nothing is added to the water and it does not change the taste or odour of the water. If you choose to install a system complete with pre-filtration, the carbon filter helps to remove any unwanted taste or odour from the water. In some rare circumstances, untreated sulphur odour can become more noticeable after UV treatment.

Ultraviolet disinfection is an very effective way to get rid of microbiological contamination in water. However, microbes have to be exposed to UV-C light in the right amounts in order for the water to be effectively disinfected.

Water quality plays a major role in how much UV is passing through it. This is called UVT, or UV Transmission. In order for the appropriate amount of UV-C light to reach microbes to disinfect water, the UVT of the water has to be ideal. Low UVT occurs when there are organic molecules or minerals in the water that absorb or scatter the UV light, allowing microbes to pass through the UV system without ever being exposed to germicidal UV-C.

Because of these pre-treatment requirements, UV is not a stand-alone technology. Basic tap water generally comes out at 85-95% UVT.

With essentially all types of UV treatment, it’s recommended that the UV system be preceded by a 5 micron filter. UV pre-treatment will make your water taste and smell better and ensures that your UV system is working at maximum efficiency to protect you and your family 24/7.

Our Whole House Systems and Point of Use Systems are complete units that includes pre-filtration by using a sediment filter followed by a carbon filter which the water will pass before reaching the UV-chamber.

Some of our customers in Thailand with very bad water quality choose to install a sand or multi-media filter before the VIQUA system to take care of bigger particles and dirt in the water.
