Best UV Water Purifier Systems: Great Deals!

Benefits of Investing in a Great UV Water Purifier System

We are extremely fortunate to have a clean water supply and top-notch treatment facilities in the United States, as anyone who has visited a developing nation can attest.

However, there are still a lot of ailments that are transferred by contaminated water. According to the CDC, 7.2 million Americans fall ill with infections that are transmitted through water each year.

Every homeowner wants access to pure water that is devoid of viruses, germs, cysts, and other microorganisms. UV destroys the water’s bacteria as opposed to other technologies that filter out these contaminants.

You run a substantially higher chance of having contaminated water if you have a well. Fortunately, UV water purifiers can shield you from dangerous germs. But which ones are worthwhile investing in?

Our buyer’s guide will provide you with all the details you need to make an informed choice after we’ve studied the best UV purifiers available and evaluated them based on their key features to determine which UV Water Purifier performs the best for you..

Buyer’s Guide For The Top UV Water Purifiers

What is UV Radiation?

Between visible light and X-rays in the electromagnetic spectrum comes UV radiation, which is invisible electromagnetic energy. Up to 3 to 5 percent of the solar energy from the sun’s rays—or UV—is found in sunlight naturally.

UV radiation is divided into three subtypes: long-wave, medium-wave, and short-wave UV-A, UV-B, and UV-C, respectively. There are several advantages to UV filtration, even if excessive exposure to it may harm live tissue and raise our chance of developing skin cancer.

UV light is essential for the production of vitamin D and may be used to treat skin diseases like eczema. Due to its germicidal qualities, UV system is also used to disinfect water.

What is a UV Water Filter?

An efficient system for eliminating bacteria, viruses, cysts, and other live creatures that are occasionally found in drinking water is an UV filter, often known as a UV water purifier or a UV water steriliser.

Installed at the main water pipe at the point of entry into your home, this device has the appearance of a long, thin bulb.

Components of a UV Purification System

Four major components make up UV purifying systems.

  • Reactor Chamber

The system’s reactor chamber is where the quartz sleeve and UV light are kept. The chamber also regulates the water flow through the apparatus. The reactor chamber is typically constructed of stainless steel, but some chambers may be made of different materials, such plastic.

  • A UV lamp

UV-C radiation, which is known to be germicidal, is produced by the UV lamp. A mercury bead found in UV lamps is essential to the generation of UV-C light beams.

The mercury in UV lamps is heated by the filaments’ electrical current, which causes the mercury to vaporise in the UV lamp’s interior air space. The electrical arcs produced by the electrically arced mercury then produce UV-C with varying degrees of strength, which purifies water.

  • Quartz Sleeve

The quartz sleeve is a glass tube that is long and cylindrical in shape. The sleeve prevents the UV lamp inside from coming into contact with the water. Through the tube, the lamp emits UV light that reaches the water. You must clean the sleeve every time the UV lamp is changed to prevent a decline in functionality since pollutants can cloud it.

  • Controller Unit

The controller unit serves as the UV purifying system’s central nervous system. The device powers the UV lamp and regulates its electrical output to generate the UV-C radiation required to kill germs.

The complexity of controllers might vary depending on the needs of the system. Others feature additional components, such as lamp-change timers, low-UV alarms, and trouble signalling lights to notify the owners in the event of a system failure. Some are as basic as a cap fitting over the end of the lamp.

How do UV Water Purifiers Work?

By using a UV lamp to sterilise the hazardous microbes, UV water purifiers generate clean water, which includes eliminating microbiological pollutants, which can be harmful to your health, including bacteria, viruses, and protozoa.

The UV lamp in UV water purifiers generates UV rays with a wavelength that is ideal, typically 254nm (UV-C). These microbes’ outer cell membranes are penetrated by the UV radiation released, which then passes through the cell body and damages the DNA.

The intrinsic chemical links of the DNA are broken when UV-C light is absorbed, which changes the DNA and hinders reproduction. The bacteria thus loses its ability to reproduce and becomes sterile.

UV rays from UV water purifiers does not eradicate bacteria. By targeting their DNA, it renders them inactive and keeps them from reproducing to form colonies. These microbiological pollutants’ DNA is primarily designed for replication.

Waterborne diseases like cholera, typhoid, dysentery, and guinea worm sickness are caused by the ability of these dangerous active microorganisms to reproduce, multiply, and form colonies.

Disinfectants, however, can allow these dangerous germs to enter our bodies and pass through without doing any harm because they have rendered them inert.

There are two types of disinfectants: chemical and physical. UV radiation is a type of physical disinfectant that works well for disinfection because it doesn’t change the chemical makeup of water. Chlorine and other chemical disinfectants react with water to change its composition and affect its flavour and odour.

Advantages of Using a UV Filter

There are several benefits to using a UV water filter, whether your home gets its drinking water from the public water system or a private well. You can gain from utilising a UV purification system to cleanse your water by:

  • Chemical-free disinfection

In contrast to other techniques, UV water purifiers don’t add chemicals to water or change its chemical makeup. Simply by passing a light across the water, it successfully destroys the hazardous bacteria.

  • No added flavours or odors

You won’t taste or smell anything different in your water as a result of utilising UV water purifiers because nothing is added to it. Your water will continue to taste exactly the same.

  • Virtually no maintenance

A major benefit of a UV filter is that it eliminates the need to frequently change multiple filters, which is required by a reverse osmosis system or a whole-home cartridge-based system. Simply clean the lamp case every few months, and replace the lamp about once every year.

  • Safe drinking water

Having a UV water steriliser will ensure that, even if your city’s drinking water is compromised for any reason—you never know what the future may hold—you will still have access to water that is safe to drink.

Limitations of UV Water Purification Systems

Whole home UV water filters do, of course, have some limits, just like all other water filters and purifiers, such as:

  • Does not remove contaminants

A UV water purifier is not what you need if you want to get rid of suspended particles in your water, especially toxins that alter the taste and odour of the water. Only living microbes can be killed by the system; pollutants in drinking water are unaffected.

  • Requires power to work

You won’t be able to use your UV light if there is a power outage at your house because it runs on electricity.

  • May heat up your water

It’s likely that the water under the UV lamp has warmed up if you haven’t switched on the faucet in some time. This can be fixed by turning on the faucet and letting the water go down the drain before cooler water comes.

UV Water Purifiers vs Water Filters

A water filter is not the same as a UV water purifier. A UV light is just a lengthy bulb enclosed in a metal casing, whereas a water filter is made out of a mesh cartridge, which is typically made of activated carbon or a similar material.

A filter and a UV purifier perform quite distinct functions. UV purifiers allow water to run directly through the UV tube without being slowed down by a filter, whereas water filters slow water down by trapping impurities in their medium to decrease or remove them.

As water enters your home through the incoming pipe, a UV lamp cures it. It eliminates dangerous bacteria, viruses, cysts, and other microbes in water by destroying their DNA. On the other hand, water filters cannot suffocate live things. By preventing the suspended particles from passing through the filter media, they merely remove them from the water.

When you should use a UV purifier

  • For municipal water at home

UV purifier are put in place where water enters a house. There is no guarantee that the water in your home is fully sterile, even though the water in your neighbourhood has been treated to get rid of bacteria and other microbes before it gets there. This can only be guaranteed by a UV water filter used at home.

  • When traveling

Bring a UV water purifier with you if you’re travelling or camping and don’t have access to a clean water source to make sure your water is safe to drink. You can use one of the several transportable, handheld water purifiers available for this purpose.

  • For treating well water at home

While having a private well for your home has its advantages, you need be sure it is safe for consumption before allowing your family to begin drinking it. You can make sure that all of your home’s faucets and appliances are providing clean, safe water by installing a whole-house UV water filter system.

Key Considerations When Buying a UV Light Water Filter


The cost of each UV system varies. Some can be purchased for as little as $100, but more sophisticated systems may require a substantial upfront investment. While you don’t have to get the priciest model available to perform the task, keep in mind that cost and quality are frequently related.

UV Water Purification Needs

A UV water filter will undoubtedly be useful if your goal is to eliminate living pollutants from your water. Look elsewhere if you want to enhance the flavour of your water or get rid of pollutants like chlorine. A UV light won’t make things better for you.

Water Flow Rate

GPM, or gallons per minute, is the unit of flow measurement for all UV systems. This gauges the rate of water flow or the volume of water that can pass through the system at once. In addition to having a maximum flowrate capacity, UV purification devices may also have a minimum flowrate.

Very fast-moving water will probably move through the system with insufficient UV light exposure.

On the other side, water with a very low flow rate could cause the UV lamp to overheat and get damaged. There shouldn’t be an excessively high or low flow rate. Additionally, systems that use constant flow recirculation are preferable for UV purifier units.

In gallons per minute, flow rate for UV purifiers is calculated (GPM). This is the speed at which contaminated water can be properly cleansed while still moving through the system. 12GPM is the normal purification rate for water in a whole-house UV purification system.

Water Quality

The drinking water in your home may have some characteristics that make UV water purification system less effective. A UV purification system may not be able to effectively treat water if it contains a lot of iron, calcium, or magnesium, for example, or if it has a high sediment content.

Depending on the problems your water has, installing a water softener or whole-house filter before your UV light may help.

The amount of UV radiation that reaches the microorganisms is also decreased because some impurities absorb or scatter UV light, which affects how the rays travel through water.

These typical pollutants in surface water supplies include fulvic and humic acid, as well as iron and manganese. UV disinfection is therefore most effective when applied to water that has already been filtered to remove these pollutants.

The cover provided by soil, suspended particles, and other types of floating debris may also provide protection for microorganisms. Total Dissolved Solids (TDS) should be less than 0.3 ppm and water hardness should be less than 7 grains per gallon.

Space Availability

There are many different sizes of UV systems, and some demand more space than others. Small storage cabinets are unlikely to accommodate long lights, however it is simple to find a more compact UV lamp with the same GPM.

If the space you have available isn’t suitable for vertical installation, you should also think about whether a UV system can be put both vertically and horizontally or just vertically.


The requisite UV-C, short-wave radiation must be produced by the ballast, which must be of a specific wattage. A 55 Watt, 120 Volt system is adequate for most homes.

Portable UV Purifier Units

A portable UV purifier device could be helpful in addition to water filters, which are the most typical outdoor purifying tool. Not all germs can be removed by portable water filters, however they are excellent in removing sediment and big bacteria.

All bacteria will be destroyed by UV radiation, but not sediment. When travelling outside, a portable UV device and filter like the SteriPen can be a terrific combination.

How To Choose The Right Size UV Unit?

There are many different sizes of UV water systems, so you might be unsure of how big of a system you need for your household. Everything from small, hand-held drinking systems to massive, whole-house systems that can move hundreds of gallons of water per minute is available.

Consider the following factors while choosing the right UV water purifier size for you:

Size of Your House

The greater GPM you require to effectively distribute purified water to every appliance in your house will depend on how big it is. Smaller homes, condos, or apartments should utilise 10 GPM systems, but larger residences with many bathrooms should use 15 GPM or higher systems.

Colour of Your Water

Your water’s colour can be a sign of excessive iron content or surface debris. It’s always recommended to assess if your water has a yellowish tint because this may prevent the UV rays from passing through the water properly.

Size of Your Plumbing

Even though the majority of UV systems are built to integrate effortlessly with your plumbing, it is still a good idea to research a product’s fittings before making a purchase. The flow of your water may be slowed down if you purchase a UV system that is incompatible with your plumbing.

Installation and Maintenance of a UV Purification system

Installing a UV purifier is quite complex, so you might opt to employ a plumber to take care of it for you. However, if you prefer doing things yourself and have up to an hour to spare, you may install a UV system yourself.

The installation instructions for your system will detail how to install your particular model, however if you’d want a general concept of how installation works, follow these steps:

1. Choose the location of the filter. If you’re installing a whole-house UV purifier, it probably won’t be by itself. If you use well water, the UV lamp could be used in addition to a whole-house water filter, a water softener, and a well pump.

In this instance, you just put your UV filter last so that water can pass through all of the other components you installed before it. Install your UV filter as close to the point where your water enters your property as you can if you don’t already have anything else in place.

2. Mount the lamp housing to the wall – The lamp housing for your UV lamp should be included. Using the provided mount, you may fasten this housing to the wall directly. If you decide to mount the lamp vertically, make sure to install it so that the power wires come out of the top; this helps to ensure the system can function properly.

3. Unscrew one of the lamp housing’s ends and slide your UV light inside. Use the O-rings that came with the lamp to close both ends.
Your UV lamp includes two threads: one for water to enter the system and one for water to exit the system and return to the water line. Connect your lamp to your water line using the appropriate threads. As directed by the manufacturer, connect them to your water line.

4. Turn on the water in your house – Next, turn on the water and use the appliances in your house to check for leaks.

5. Plug the UV system into the wall – The UV light must now be connected to your power by being plugged into your wall as the last step in the installation process. Make sure to connect the wire securely in accordance with your installation instructions; avoid letting the wires’ non-waterproof parts become damp.

UV water purifiers require maintenance, just like any other UV water treatment method. After 9,000 hours, or nearly every 12 months, the UV lamp itself needs to be replaced.

After 9,000 hours, the mercury in the lamp deteriorates, which lowers its efficacy, which is why you need to change the light. It only takes a few minutes to replace the light; all you need to do is remove the lamp housing from the wall, remove the old lamp, and replace it.

Frequently Asked Questions

How is the Strength of UV Measured?

Milli-joules per centimetre square, or mJ/cm2, are used to describe UV strength. According to the US Department of Health, an efficient UV purifier for drinking water applications needs to deliver at least 30,000 mJ/cm2.

Is a Whole House Filter Installed Before a UV Lamp Necessary?

If you only want to get rid of microorganisms and aren’t concerned about other toxins, installing a whole house water filter will help since it will remove the silt and other particles which could cause issues in a UV filter. However, it is not fully necessary.

What Will Happen if I Don’t Replace My UV Lamp?

Simply put, the UV light will stop working as well and won’t be as effective at killing the germs as it should be.

Is Water With UV Filters Safe?

It is safe to treat water with UV. It doesn’t employ dangerous chemicals or alter the water’s chemical makeup. By using UV-C light, it merely eliminates the presence of bacteria and viruses in your water source.

UV Purifier or UF Filter: Which Is Better?

If you want to get rid of bacteria and viruses, UV water purification is more effective. It sterilises your water by killing microbes with strong UV light.

Contrarily, a UF or ultrafiltration filter removes particles from your water by forcing water through a membrane with tiny holes, much like a normal osmosis water filter does. The fact that UF can also filter out silt and other particles is the one benefit it has over UV.
