Top 5 Best Whole House UV Water Purifier

Top 5 Best Whole House UV Water Purifiers



Looking for the best whole house uv water purifier? You’ve come to the right place. Whole house water filters or purifiers are point-of-entry systems that are able to provide purification of the water at the main water line that enters your home. In other words, by filtering the water as it is entering the home, the whole house water purifier will successfully remove sediments, rust, chlorine and more chemical contaminants providing healthy and clean water for you and your entire family. There are currently millions of households all over the world that are using point-of-use ultraviolet (UV) systems to provide clean drinking water. It’s important to note that UV water treatment can go beyond your kitchen sink and provide the same healthy water to every existing tap in your home. A UV system can provide an extremely safe solution against chlorine-resistant micro-organisms that cause health issues. There are a few things worth considering before purchasing a UV water purifier system for your home.


Factors to consider when buying the best whole house UV water purifier

The first important thing you must take into consideration when deciding which whole house UV water purifier you should get is knowing how much water you use in your home. The peak usage is essential in selecting the ideal UV system because it will help you get the right size of purifier that will offer you peace of mind by protecting your home from microbiological contaminants.

The flow rate is another critical factor, and it’s important to know that UV systems measure water flow rates in GPM which stands for “gallons per minute.” UV systems come with a GPM rating that will let users know how much water can flow through it. Here are a few general flow rate guidelines: for one bathroom, you’ll need 6 GPM, for two bathrooms, 9 GPM, for three bathrooms 12 GPM, for four bathrooms, 15 GPM, for five bathrooms, 18 GPM.

The UV dose is an essential factor worthwhile considering. The amount of UV energy that comes from the lamp to the water as it goes via the system is called the UV dose. It is expressed in mJ/cm2. You will usually need around a UV dose of 10 mJ/cm2 to inactivate Giardia, E.Coli and other harmful bacteria.

The quality of water before you use the UV system is also essential to consider. In order to be able to keep a UV system functioning flawlessly and at its top performance, it is critical to know the specific contaminants that are present in your water. For instance, higher levels of sediment, hardness, or iron may not enable the UV system to work correctly and to treat the water. The incoming water should meet these requirements: the hardness should be smaller than 7 grains/gallon, the iron should be smaller than 0.3 parts/million, the manganese should be under 0.05 parts/million, the turbidity should be under 1 NTU, the tannins should be under 0.1 parts per million, and the UV transmittance should be under 75%.

Installation and space requirements are other essential factors to consider because some UV systems are really compact and others are longer even if they are all rated at the same flow rates. UV systems are generally installed vertically, but they can also be installed on horizontal. While determining the space that you need for installing a UV system, you have to make sure that you at least double the size of the system’s dimensions. This way, you will definitely have enough room to replace the sleeve and the lamp when it’s necessary.


Tips for choosing the best whole house UV water purifier for your needs

  • Before getting a UV system, you should also consider the space that you might need for any pre-filtration systems.
  • Consider getting a standard system with an end-of-life countdown display that will indicate how many days are left until you have to replace the lamp.
  • Some high-quality systems include controllers that have LED light that show the proper function of the system’s components.
  • Other recommended systems come with touchscreen displays.
  • The most common option that is added to a home filtration system is the sensor.
  • Make sure that the initial cost of the system is not your only consideration when you’re buying a purifier because it’s important to calculate costs over the long-term as well.
  • Don’t get cheaper systems because their filter will not last long and the long-term costs will be higher.

Can Water Filters Remove Bacteria?

Water, especially drinking water, and bacteria are two things that should never go together at all. This is why water filtration and purification is highly encouraged, to prevent chances of infections from occurring. Water filtration is a two-step process which involves the actual filtration process and disinfection to remove contaminants such as coliform bacteria. In most countries, the standards do not allow the presence of any coliform bacteria in water. Examples of total coliform include fecal coliform and E. coli, which can be found in human and animal feces.

Filtration alone will not remove all harmful bacteria. Most water filtration systems have carbon filters, which remove organic compounds from your water, such as herbicides and pesticides. However, carbon filters on their own cannot remove dissolved inorganic contaminants and dangerous microorganisms. Viruses that are between 20-400 nanometers in size cannot also be removed by carbon filters.

Not all filters are created equal

Different water filters have different functions. However, no single filter can remove all types of contaminants 100%.

Filtration of contaminants highly depends on the number of contaminants, size of the contaminant particle and its charge in the water. Contaminants in this case, refers to bacterial components.

For carbon filters to remove bacteria, they have to work with other physical and chemical components such as iron, manganese and hydrogen sulfide. You will also need to consider addition of coagulants, adjustments to pH or chlorine concentration levels and other pre-treatment processes. The carbon filters must also be of high quality.

How can you ensure water filters remove bacteria?

For complete removal of bacteria through filtration and purification processes, four methods can be used which include microfiltration, ultrafiltration, nanofiltration and reverse osmosis system.

  • Microfiltration

A microfiltration filter usually has a pore size of approximately 0.1 micron (normal pore size ranges vary by filter from 0.05 to 5 micron).

The microfiltration process is very effective for removing protozoa, bacteria (including E.coli) and viruses. Its main limitation is that it is not quite effective for removing chemicals.

  • Ultrafiltration

The ultrafiltration process removes particles based on size, weight and is effective for removing protozoa and bacteria. However, it is moderately effective for viruses. It also has low effectiveness in removing chemicals.

  • Nanofiltration

Nanofiltration is very effective for removing protozoa, bacteria and viruses. However, it has a moderate effectiveness in removing chemicals.

  • Reverse osmosis system

Reverse osmosis system is a process that involves the reversing the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more diluted solution through a semi-permeable membrane. Both pre and post-filters are included in the reverse osmosis membrane process itself.

The reverse osmosis system is highly effective for the removal of protozoa, bacteria, and viruses. It will also remove common chemical contaminants, metal ions and salts.


Your water filtration system will need constant maintenance to ensure its performance is maintained at optimal levels. Carbon filters will require regular filter replacements, to prevent build-up of bacteria and other contaminants in the system.
