Writers Top UV Water Purifier Systems Picks
We in the United States are extraordinarily fortunate to have one of the cleanest and safest water systems on the globe. Despite this, the Centers for Disease Control and Prevention estimates that approximately 7.2 million Americans become ill from waterborne infections each year.
Having a well increases your risk of water contamination by a factor of several hundred percent. Fortunately, ultraviolet (UV) water purification systems can protect you from hazardous bacteria in your water. But which ones are worth your money in the first place?
If you are having difficulty deciding on a UV water purifier, you have arrived at the correct place. Years of industry experience, as well as essays published in magazines such as WQP Magazine, WWD Magazine, and Sawyer Products, have equipped me with a thorough understanding of the water treatment industry.
I started WaterFilterGuru.com in order to share my knowledge with other like-minded individuals, and my website currently receives an average of 100,000 unique visitors every month.
The dependability of a UV water purifier is the most significant attribute to look for. As a result, this list is short and sweet – there are only four purifiers on it that I am confident in recommending based on their high level of performance and customer happiness, as detailed below.
UV Light Water Treatment System
How to choose the right size UV unit
There is a wide range of sizes available for ultraviolet water systems, and you may be unsure of how to select the most appropriate size for your household. Every type of drinking system is available, ranging from small handheld and portable units to massive whole-house systems with flow rates of hundreds of gallons per minute or more.
Consider the following:
Your home’s size
The greater the size of your home, the higher the GPM you will require to efficiently deliver filtered water to all of the appliances in your home. Systems with a flow rate of 10 GPM are appropriate for modest houses, condos, or apartments, whereas systems with a flow rate of 15 GPM or higher are appropriate for big residences with more than one bathroom.
If there is color in your water
The presence of color in your water could suggest a high concentration of iron or surface debris. As a result, if your water has a yellowish hue, it is always better to size up because the UV rays may not penetrate as efficiently through the water as they should.
The size of your plumbing
Despite the fact that the majority of UV systems are designed to integrate effortlessly with your plumbing, it is still a good idea to research a product's fittings before purchasing it. It is possible that purchasing a UV system that is not compatible with your plumbing will cause the flow rate of your water to be restricted.
Springwell Blackcomb UV Water Filter System is an excellent alternative if you're looking for a system that provides guaranteed protection against bacteria and other contaminants. This water purifier destroys 99.9 percent of bacteria, as well as viruses and other common drinking water contaminants, according to the manufacturer.
The Springwell Blackcomb is intended for whole-house use, and it can be used either alone or in conjunction with a whole-house water filter system, depending on your preferences. Although the purifier operates at a high rate of 30 mJ/cm2, its 15 GPM flow rate assures that there are no drops in water pressure while the device is in operation.
An IP65-rated enclosure protects the UV lamp from water damage. In addition, it has a user interface that provides real-time information on the remaining lamp life of the device, as well as any faults. You can utilize the QR codes that are provided to gain access to online information and videos that will assist you in changing the lamp.
Although the Springwell Blackcomb does not come with a sediment filter, Springwell suggests that you purchase one at an additional cost in order to preserve the lamp from damage.
The Acuva Arrow is a UV-LED water purifier that may be used to treat water from a kitchen faucet, bathroom faucet, dedicated drinking water faucet, or ice machine at the point of use.
This UV lamp produces cleaned drinking water at a rate of up to 1.3 gallons per minute without disrupting water pressure. The item is available in two voltages: DV 12V and AC 120/240V.
The Acuva Arrow's most appealing feature is its exceptionally extended lifespan. This filter is expected to last up to ten years and purify 900,000 liters of water during that time. The Acuva Arrow is an excellent option to consider if you're searching for a UV purifier that's almost maintenance-free.
With a body casing made of high-quality aluminum, the unit boasts a strong, long-lasting construction. The Acuva Arrow comes with mounting tools, plumbing supplies, and power for installation (DC or AD). A sediment pre-filter is provided with the Acuva Arrow, however you can use whatever pre-filter you want with this purifier.
The Viqua VH410 is a high-capacity ultraviolet (UV) water purifier that can handle water flow rates of up to 18 gallons per minute. Because of its ultra Violet output, this UV water filter is compact in size, allowing you to save space while still achieving performance comparable to that of a larger chamber.
Depending on your requirements, you can install the Viqua VH410 alone or in conjunction with a water filter. Always keep in mind that the VH410 will not remove particles or chemicals from water, such as chlorine, which, while not harmful to your health in small amounts, may still have an impact on the taste and odor of your water.
When installing the Viqua VH410, you won't need to hire a plumber to help you because the instructions are included. It is intended for easy do-it-yourself assembly and can be installed vertically or horizontally (vertical is recommended). The lamp and filter housing, as well as the bracket for wall mounting, are all included in the price of the package. It's important to note, however, that you'll need to purchase the fittings necessary to connect the Viqua system to your water line.
The Viqua VH410 can be used with both city and well water, and it is widely regarded as the best UV water purifier available for eliminating bacteria and cysts such as E.Coli, Salmonella, and Giardia, among others. Its mechanism of action involves targeting the DNA of these microorganisms and killing them while also preventing them from reproducing. The VH410 lamp, which promises a consistent high output, will continue to perform at its peak throughout the entire lamp's lifespan.
When the lamp in the Viqua VH410 has been used for approximately 9,000 hours (equivalent to approximately a year), it will need to be replaced with a new one. The purifier is equipped with a lamp replacement reminder, which will sound when it is time to replace the existing lamp. The unit has an additional feature: a digital countdown screen, which you can use to keep track of the unit's performance and to schedule the purchase of a new lamp in advance.
Aside from changing the lamp, there is very little additional maintenance required. It is necessary to clean scale and build-up from the lamp sleeve on a regular basis, approximately every three months. The user manual contains instructions on how to do this in a safe and secure manner. The flow rate will remain constant at 18 GPM or higher depending on the inflow water flow rate of your home throughout its entire lifespan, so there is no need to do anything to increase it. Because of this, you will never have to deal with a decrease in water pressure in your faucets or showers again!
The UV light water purifier from Pelican targets pathogenic organisms that can cause illness and disease in humans, such as bacteria, viruses, and cysts, in drinking water.
This environmentally friendly system has a peak flow rate ranging from 9 to 16 GPM, making it suitable for use in the majority of households. Because the Pelican system is capable of removing only living microorganisms from water, it will have no effect on the current taste, odor, or appearance of the water in your home.
The NSF 55 Class B certification of the Pelican premium system distinguishes it from other UV water filter systems on the market. This certification provides assurance that the system is designed for supplemental treatment of drinking water to remove bacteria, and that the system has been third-party tested and determined to be safe for human consumption (drinking water).
The Pelican unit is an excellent choice if you are looking for a simple UV purification system. Basically, all you have to do is remember to clean the lamp sleeve every couple of months and to replace the lamp once a year. Both of these procedures are extremely straightforward and can be completed in a matter of minutes.
The Pelican UV purification system employs a type of UV disinfection known as thymine dimerization, which is unique to this system. When ultraviolet (UV) light penetrates the DNA of living microorganisms in water, the DNA is permanently altered, making it impossible for the microorganisms to reproduce or infect a person who drinks the contaminated water.
If you're having trouble visualizing what this might look like, the manufacturer provides an excellent analogy: a broken zipper. It is no longer possible for the DNA to “zip back up” because the mechanism that holds it together is no longer functioning properly.
The unit includes a useful lamp age display, which counts down the number of days until it is time to order a new lamp, ensuring that you never fall behind on lamp replacements. When you have 30 days left before you need to replace the system, a light on the system will turn yellow and an alarm will sound, giving you plenty of time to place an order for a replacement.
Identifying a UV light that is safe to leave in the vicinity of small fingers may be critical for families with young children. The Pelican premium UV disinfection system is equipped with a safety cap that prevents young children from gaining access to the lamp or any of the other electrical components. Additionally, the lamp is equipped with a special plug that prevents you from being able to power it up while it is not safely contained within the UV chamber.
Pulsar UV Disinfection System, manufactured by US Water Systems, is one of the most recent UV disinfection systems to be introduced to the marketplace. This whole-home application deactivates microorganisms in a matter of minutes, rendering them incapable of reproducing or infecting humans or animals.
A reliable and consistent UV output is guaranteed throughout its 9,000-hour lifespan, thanks to the design of the Pulsar. The full-color LED screen that comes with the system provides all of the information you need to keep track of the system's performance.
Sediment in water can interfere with the proper operation of the UV process because it prevents UV light from fully penetrating the water. The Pulsar is equipped with a sediment pre-filter with a 1-micron pore size that removes sand, salt, and dirt particles from the water before it passes through the system.
The Pulsar is similar to the majority of UV systems in that it is simple to install and requires little maintenance – you will only need to replace the lamp on an annual basis (and you can do this without interrupting water flow).
A warning message will be displayed on the system's display when the lamp needs to be replaced, and an alarm will sound if the system fails to notify you in advance.
Numerous features help to maximize the efficiency of The Pulsar and ensure that the UV disinfection process is as safe as it possibly can be for users. Its corrosion-resistant stainless steel chamber aids in the preservation of UV light, and the power supply is housed in a water-resistant enclosure to prevent accidental water damage.
When it comes to water treatment, the Viqua D4 Premium is a whole-house ultraviolet (UV) system that is primarily used to remove bacteria from water, making it perfect for residential homes that use well water. When used with a flow rate of up to 12 GPM, this UV filter enables fast, effective water treatment that will have no effect on water pressure in your shower or other water-based appliances.
One of the things that distinguishes the Viqua D4 from its competitors is its modest, compact size. It takes up less room and has a lesser environmental impact than a longer UV chamber, yet it provides the same performance as the longer one. Because of its constant current feature, this UV lamp will not go out even if your power goes out, ensuring that you always have access to safe drinking water.
It is expected that the Viqua model D4 will provide you with just over a year of use before it has to be replaced due to its 9,000-hour lamp life. The system is installed at the point of entrance into your home, and most individuals find the installation to be simple enough that they can do it themselves. All you have to do now is insert the UV lamp into the sleeve and connect the system directly to your water line, following the installation instructions provided by Viqua.
When it comes to bulb life and UV intensity, the Viqua D4 Premium won't leave you in the dark with this model. You may use the interactive display screen to see all of the information about your UV filter's health at a glance. This will assist you in troubleshooting any difficulties that may emerge and planning to replace your UV filter's lamp before your current one runs out of life. In addition, the firm logo and contact details are displayed on the screen in case you need to contact customer support for assistance.
Replaceable components for the Viqua may be purchased on the internet for a reasonably modest price – replacement bulbs for the Viqua, for example, cost less than $100 and will only need to be purchased once each year. You will only need to perform semi-regular maintenance on your lamp housing aside from changing it when the lamp burns out. When compared to alternate bacteria removal filters, such as RO systems, there are no filters to replace on a half-yearly basis, and there is also no need for backwashing.

What is an Ultraviolet Water Filter?
An ultraviolet water filter, also known as a UV water purifier or a UV water sterilizer, is a system that is effective at killing bacteria, viruses, cysts, and other living organisms that are sometimes found in drinking water. It is also known as a UV water purifier or a UV water sterilizer.
This system, which resembles a long, thin lamp, is installed at the point of entry into your home, where your main water pipe meets the water main.
Advantages of Using a UV Filter
There are a number of advantages to using an ultraviolet water filter, whether your home's municipal drinking water or a private well water source is the source of your concern. When you treat your water with a UV purification system, you can reap the following benefits:
UV disinfection, in contrast to other methods of cleaning, purifying, or disinfecting water, does not introduce chemicals into the water or change its chemical composition. It simply kills the harmful microorganisms by shining a bright light through the water, which is very effective.
No added tastes or odors
Using a UV filter will not change the taste or smell of your water because nothing is added to it. You will not notice any difference in the taste or odor of your water after using a UV filter. Your water will continue to taste exactly the same as it has in the past.
Virtually no maintenance
When using a UV filter, you won't have to change as many different filters as you would with a reverse osmosis unit or a whole-home water filter, which saves you time and money. All that is required is that you clean the lamp case every couple of months and replace the lamp approximately once a year.
Reassurance of safe drinking water
If your city's drinking water is compromised for any reason, having a UV water sterilizer will ensure that you will still have access to water that is safe to drink in the event that your city's water supply becomes contaminated.
Limitations of UV water purification systems
To be sure, as with all other types of water filters and purifiers, whole-house UV water filters have a number of limitations, including the following:
No contaminant removal
If you are looking for the removal of suspended particles in your water, including contaminants that affect the taste and odor of your water, a UV water purifier is not the right choice for you. The system is only capable of killing living microorganisms and has no effect on contaminants found in drinking water.
Needs power to run
In the event of a power outage in your home, you will be unable to use your UV lamp because it is powered by electricity.
May heat your water
Especially if you haven't turned on the faucet in a while, it is possible that the water sitting beneath the UV lamp has become warm. Run the faucet for a few seconds to allow this water to pass through before more cool water arrives. This will solve your problem immediately.
How Does a UV Water Purifier Work?
A UV light water purifier is a simple device that eliminates microorganisms and prevents them from multiplying in water by using ultraviolet light.
It disinfects water by exposing it to germicidal ultraviolet light, which targets and scrambles the DNA of the microorganisms that inhabit the water.
Microorganisms that have their DNA scrambled are unable to reproduce or behave in the way that they would normally. This means that you can safely drink water that contains bacteria and viruses after it has been treated with a UV water purifier, and you will not become ill as a result.
UV Water Purifiers vs Water Filters
A UV water purifier is not the same as a water filter, and they are not interchangeable. The first thing to note is that they have a completely different appearance – a UV light is essentially a long lamp enclosed in a metal housing, whereas a water filter is comprised of a mesh cartridge, which is typically made of activated carbon or a similar material.
Furthermore, the function of a water purifier is vastly different from the function of a filter. While water passes through water filters, which reduce or remove contaminants by trapping them in their media, UV purifiers allow water to flow directly through the UV tube without being slowed down by a filter. Water filters reduce or remove contaminants by trapping contaminants in their media.
An ultraviolet (UV) lamp treats the water as it enters your home through the inlet pipe. It kills harmful bacteria, viruses, cysts, and other microorganisms in water by damaging the DNA of the microorganisms that are alive at the time of treatment. A water filter, on the other hand, will not be able to eliminate living organisms. It is simply a matter of stopping suspended particles from passing through the filter media.
When you should use a UV purifier
You have the option to use the best UV water purifiers whenever you want to. Many people prefer to use UV disinfection for a variety of reasons:
For at-home municipal water
UV purifiers are installed at the point of entry of water into a home to purify it. However, even though the water in your neighborhood has been treated to remove bacteria and other microorganisms before it reaches your home, there is no guarantee that the water in your home is completely safe. This can only be achieved through the use of a UV light water filter at home.
It is possible to bring a UV water purifier with you if you are traveling or camping and do not have access to a clean water source. This will ensure that the water you are drinking is safe to drink. There are a variety of portable, handheld water purifiers that you can use for this purpose, including:
For treating well water
Having your own private well water source for your home has its advantages, but you must be certain that the water is safe to drink before you allow your family to begin drinking it. Installing a whole-house UV water system can help to ensure that all of your home's faucets and appliances are producing clean and safe water.
Key considerations when buying a UV light water filter
There are several factors to consider before making a decision on whether or not to purchase a UV water filter. These are some examples:
It is within your financial means.
Not all ultraviolet water treatment systems are the same price. Some systems can be purchased for as little as $100, while more advanced systems can cost several hundred dollars up front. While you are not required to purchase the most expensive model on the market in order to complete the task, keep in mind that price and quality are frequently associated with one another.
Your requirements in terms of water purification
In the case of removing living contaminants from your water, a UV water purifier will unquestionably be of assistance. However, if you want to improve the taste of your water or get rid of chemicals such as chlorine, you should look elsewhere. A UV light will not make your situation any better.
The amount of water that flows through your system
The flow rate of all UV systems is measured in GPM, which stands for gallons per minute. This metric measures how quickly or how much water can flow through a system at one time, depending on which is greater. Although it is preferable to purchase a system with a higher flow rate for your home, knowing the flow rate of your home will assist you in making the best decision.
The quality of your water
When it comes to the drinking water in your home, certain characteristics of the water may make it more difficult to perform effective UV water treatment. In some cases, high sediment levels in water, as well as water containing high concentrations of iron, calcium, and magnesium, may prevent a UV system from properly treating the water. It may be beneficial to install a whole-house water filter or a water softener prior to installing your UV lamp, depending on the problems your water is experiencing.
You have a limited amount of available space.
UV systems are available in a variety of shapes and sizes, with some requiring more space than others to be installed. Small storage cupboards will not accommodate long UV lamps, but finding a more compact UV lamp with the same GPM is not difficult. If your available space does not allow for vertical installation, you should consider whether a UV system can be installed both vertically and horizontally, or whether it can only be installed vertically.
Installation and Maintenance of a UV purifying system
Installation of a UV purifier is considered to be of medium difficulty, and you may find it more convenient to hire a plumber to complete the task for you. A UV system, on the other hand, can be installed by the homeowner if he or she is interested in doing it themselves and has up to an hour available.
If you want a general idea of how installation works, here's what you'll need to do in most cases:
Choose a location for the filter – If you're installing a whole-house UV purifier, it's unlikely that the filter will be installed alone. If you have a well pump (if you use well water), a water softener, and a whole-house water filter, the UV lamp may be a good addition to your water treatment system. It is sufficient to install your UV filter last in this case, so that water can pass through everything else that has been installed before it. If you don't have anything else in place, you can simply install your UV filter as close as possible to the point where your water enters your home to prevent contamination.
Make a wall mount for your UV lamp housing – Your UV lamp should come with a wall mount for it. Using the included mount, you can mount this housing directly to a wall without any additional hardware. If you choose to install the lamp vertically, make sure that the power wires exit through the top of the lamp; this will help to ensure that the system functions properly.
After removing one end of the lamp housing, slide your UV lamp into the housing and seal the lamp on both ends with the O-rings that came with the lamp.
Connect your UV lamp to your water line – Your UV lamp has two threads, one for water entering the system and another for water exiting the system and returning to the water line. Connect the two threads together. Connect these to your water line according to the instructions provided by the manufacturer.
Turn on your home's water supply – The next step is to check for leaks by turning on your water supply and using the appliances in your home.
Lastly Plugin the UV System, connect the UV system to your electrical system by plugging it into your wall. This completes the installation process by bringing the UV system up to your electrical system. Keep in mind to connect the wires in a safe manner according to your installation instructions – don't allow the non-waterproof areas of the wires to become soaked.
UV water purifiers require maintenance in the same way that any other water treatment process does. For the UV lamp itself, it is recommended that it be replaced every 12 months, or after 9,000 hours of use.
One of the reasons why you need to replace the lamp is that after 9,000 hours, the mercury contained within it begins to degrade, decreasing its overall efficiency. It takes only a few minutes to replace a lamp – all you have to do is remove the lamp housing from the wall, slide out the old lamp, and slide in the new lamp to complete the task.
In addition, you should clean the quartz glass sleeve that is located inside your UV water filter. If your water contains high levels of hardness or iron, it will cloud the screen of the glass, preventing the UV wavelengths from passing through it. In order to prevent this from happening, it is recommended that you clean the sleeve approximately every two to three months.
Frequently Asked Questions About UV Water Purifier Systems
Is it possible to extend the life of my UV lamp by turning it off when I'm not using it?
This theory makes sense, especially if you have a vacation home with a well water source and don't want to leave your UV light turned on while you're away from home. Unfortunately, turning off your UV lamp when you aren't using it is a bad idea for a variety of reasons. As a result, if you want your lamp to have a long lifespan, you should leave it on as much as you possibly can while doing so.
What is the method for determining UV strength?
In the case of a UV lamp, the power, or strength, is measured in millijoules per centimeter squared, also known as mj/cm2. UV water filters provide at least 30,000 millijoules per cubic centimeter of surface area, according to the US Department of Health. The number of mJ/cm2 that a UV system produces can usually be found in the product description. If a system is NSF Class B certified, it means that it has passed all of the necessary tests and has more power than the minimum required power of 30,000 mj/cm2.
Is it necessary to install a whole-house water filter prior to installing my UV lamp?
If you are not using well water, then the answer is no – but it is strongly advised. A filter will allow contaminants and particles that could interfere with the ultraviolet process to be removed from water before it passes through the UV light, allowing the process to run more smoothly.
What is the effect of installing my UV lamp vertically? Does it make a difference which way the water enters and exits the lamp?
Yes, the water should enter the lamp through the bottom fitting and exit the lamp through the top fitting, as shown in the diagram.
If I don't change my UV lamp when it's supposed to, what will happen to me?
For starters, your light will no longer function properly because the UV intensity will have degraded to such an extent that it will be rendered ineffective. Even if the lamp is still on, it does not necessarily mean that it is having a significant impact on your water.
What is the best way to ensure that my UV system is operating properly?
One of the most straightforward options is to purchase a laboratory water kit, which will allow you to test your water both before and after using the UV lamp. A UV lamp will be able to kill most bacteria, including coliforms and E. coli, so look for testing kits that detect bacteria such as these.
