Why choose a water filter with UV-disinfection?

UV disinfection of water has a long and well-proven history and is installed in many public drinking water treatment plants all over the world, for example in New York City. Discover this video that explains more about the history and technology of UV water disinfection.

What our customers say

Best high quality water filter you can get in Thailand. Great service and the sales staff is very knowledgeable about what the best solution is for you.

Johnny Westerly

My sporty family consume large quantities of water every day, so we decided to purchase the VT1-DWS water filter. It has made significant improvements in our lives with clean, fresh & safe drinking water. The service and professionalism that we received was excellent.

Jim Andrews

I want my children to be able to drink good and bacteria free water that still gives them the minerals. The Viqua water filter was just what we were looking for, we were very happy with all the help from the owner and his staff when we discussed what kind of filter we should buy. Thanks!

Common questions about our Water Filters

Municipalities work very hard to provide safe water for their customers. In some areas of Thailand, the water leaving the treatment plant is considered safe to drink. However, that water then moves through a vast distribution system that in many cases is aged and can lead to contaminations. The water that then reaches your home is often far from safe to drink. A UV Disinfection System gives you and your family peace of mind and is a very affordable insurance policy against the possibility of coming in contact with water contaminated with microbes.

Yes you can. However, in many areas of Thailand, well-water means hard water or a lot of iron, manganese or other substances in the water. In these cases we always recommend our customers to speak to us, our local partner or another local water treatment company first to get accurate information about water quality in the local area and advice on whether additional treatment is needed before installing the system.

No. UV Systems are designed with correctly sized inlet/outlet for the specific application.

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.

We distribute 3 types of systems in Thailand.

Whole House Systems

A Point of Entry System complete with pre-filtration plumbed straight in to your water line. This gives you safe, disinfected water straight from any outlet or tap in the house. Basically safe drinking water everywhere in your home.

Point-of-use systems

A smaller system complete with pre-filtration that can be installed anywhere in or outside your home to provide safe, disinfected water for a single tap and maybe also a refrigerator with ice-maker or a coffee machine depending on the capacity of the system. This system can be installed under the kitchen sink and used with your existing kitchen tap without the need for a separate “drinking water tap”.

Stand-alone UV Systems

This is a UV disinfection system without any pre-filtration that can be installed anywhere in or outside your home to disinfect your water. Maybe you already have your own pre-filtration and only want to add UV-disinfection. Then a stand-alone UV-system is what you are looking for.

The ultraviolet (UV) treatment process is an extremely quick physical process. Ultraviolet light mutates and/or degrades DNA. DNA (or deoxyribonucleic acid) is the part of the cell that gives an organism its instructions on how to function and reproduce.

When the DNA is damaged, the organism becomes unable to function because its “instructions” are garbled or missing. An organism that has no instructions cannot function and reproduce, and cannot cause infection. It is rendered harmless and eventually dies.

In the UV disinfection process, water is purified as it runs through a stainless steel chamber (also called a “reactor”) that contains a special UV- producing lamp. As the water flows past the lamp, the microbes in the water receive a lethal dose of UV. The water is then safe to drink.

UV disinfection typically offers a 4-log reduction (99.99%) for both bacteria and most viruses. UV is more effective than chemical disinfection processes at destroying a wide range of viruses.
