Features & Advantages

Chemical-free Disinfection
The Viqua D4 Ultraviolet System is a chemical-free alternative for any home in the need of water disinfection. This system uses UV light to
sterilize harmful bacteria, viruses
and microorganisms like:

  • Cryptosporidium
  • Giardia
  • E. Coli

The Power Of UV
This system uses ultraviolet light to sterilize viruses and bacteria. The UV light literally breaks the bond of the molecules inside the DNA of viruses and bacteria, making them unable to reproduce.
By changing the DNA, we are able to en-
sure that those microorganisms are
completely disinfected, and can no
longer cause harm or illness.
Added Protection
Get added protection with our custom assembled Sediment Prefilter Kit. This kit comes with a 50/5 micron graded density polypropylene sediment filter, which reduces the presence of dirt, sediment and turbidity in your water. It is vital to pre-
filter your water because the presence of dirt and sediment can clog and damage your UV system. This kit includes:
