Getting a UV water filter means that you have a filter that uses ultraviolet light to treat and purify your water.
All home UV filters should be equipped with a pre-filter system. This is because a UV filter is not so good at dealing with large bits of dirt, sand, debris or particles. So using a pre-filter to remove any larger pieces of dirt will make the UV filter work more efficiently.
It is also important to note that UV water filters do not eliminate chemical contaminants. This also includes things like VOC’s (volatile organic compounds), heavy metals or suspended solids. They can, however, disinfect relatively clean water and destroy harmful microorganisms.
For a more complete filtration I recommend adding UV water filters to an existing whole house filter or softener. This article will review some of the best stand alone UV filters as well as those available as a whole house filter upgrade.

UV Treatment Private Water Supply
Some UV filters for the entire house can be supplied with filter cartridges that can also attack other contaminants. For example, the Pentek UV 110-2 7.6 LPM water filter system is supplied with a filter block for carbon blocks. This reduces the bad taste and odor, chlorine, salt. But also other substances like, cysts, cryptosporidium and giardia from your water. The system can produce 7.6 liters of purified water per UV per minute.
Some of the contaminants eliminated by UB filters include:
- Microorganisms (e.g., Cryptosporidium, Giardia, E-coli, Pseudomonas, etc).
- Chemical disinfectants and their derivatives. E.g. hormones, VOC’s volatile organic chemicals, organic, herbicides, toxins,and pesticides.
- Heavy metals.
- Hydrogen sulfide.
- Bad taste, bad odors etc.

HQUA-TWS 12 Ultraviolet Water Purifier Sterilizer Filter for Whole House Water Purification
It is believed that giardia, cryptosporidium and e. coli are the major microbial problem that often occurs in private water sources that cause disease in humans. Most people are familiar with e.coli because it is often discussed in the media as a contaminant in food, but it is also a water polluter.
The UV water purification system is considered an effective device for these problems. Not only does it provide a better taste, it also provides additional health insurance for your family.
The ultraviolet (UV) treatment process is an extremely fast physical process. Ultraviolet light mutates and / or degrades DNA. When DNA is damaged, the organism can not function because its “instructions” are distorted or missing. An organism without instructions can not work or multiply and can not cause infection. It is harmless and eventually dies.
In UV disinfection, the water is purified while passing through a stainless steel chamber (also called a “reactor”) containing a special UV lamp. When the water passes through the lamp, the microbes in the water receives a lethal UV dose.

UV Water Filter Price?
A stand alone basic UV filter can cost upwards of $250. This does not includes professional installation and you may have to up a pre-filter to deal with large particles.
A UV add on / upgrade to an existing whole house filters can cost between $1850 – $3500 (for the whole filter package). High performance water filters and those that can deal with larger capacities can cost double or even triple that amount. This is especially the case if they combine filters with carbon filters, ceramic filters or activated carbon granulate filters. And they process the water in a multi-stage fashion like Aquasana 10-year Rhino or OptimH20. The bottom line is they are worth it because the process of these filters reduce an impressive number of contaminants.
Common UV Filter Problems
Here is a list of some of the common mistakes that people make when using UV filters. Understanding these problems will mean that you avoid them and that you can use your UV filters worry free.
People always get tempted to buy the cheapest UV filters they can find. There are many cheap plastic / low quality material ultraviolet water systems that are usually Asian import models available online. Don’t be seduced by the low prices as they are very unreliable and sometimes extremely dangerous.
Buying a stand-a-lone UV filter is not always a good idea unless you are only worried about low-medium amounts of bacteria. The best UV filters are part of a multi-stage water filter like the upgrade options for the Aquasana Rhino and OptimH20.
A UV filter on its own is unlikely to take care of all your water needs e.g. hard water issues, lead contamination or debris like sand and dirt. If you’re going to spend that type of money then you should really get something that will take care of everything like the OptimH2O.
The Best Domestic UV Water Filter?
Ultraviolet (UV) water treatment systems are primarily for the treatment of private water supplies. Supplies such as local water companies, water tanks, wells, or water sources that are susceptible to bacteria, viruses and other microorganisms.
UV water treatment systems may be the best way to kill bacteria, viruses and other microorganisms in water.
The best stand-a-lone domestic UV water filter is the HQUA-TWS.
However, if you’re getting a whole house water filter then you should get one from Aquasana and then OptimH20.
