Why Choose the Yarna UV Water Filter

Have you ever wondered how a UV water filter works? The explanation is relatively simple once you know a bit of context. In this article, we will explain it all and show you how the Yarna UV water filter improves on the classic UV water filter design.


How does a UV water filter work?


To put it simply, a UV water filter emits UV-C rays similar to the ones emitted by the sun. In case you were wondering why so few people catch colds during hot summer days, it’s because said rays eliminate bacteria, viruses, and other pathogens.


It works by using a UV lamp encased in a quartz tube that treats the exposed water flowing through a transparent pipe. The UV-C rays act directly on microorganisms’ base DNA structure to effectively disable them. In short, pathogens will no longer be able to multiply or bind to your cells and infect you.


The best part is that maintenance is super easy – you only need to change the bulb once per year. And although it consumes electricity, it won’t noticeably increase your energy bills. A UV water filter doesn’t modify the structure of the water, nor does it add any unwanted chemicals. It’s all done through the magic of ultraviolet rays. It’s a much more effective method of ridding bacteria from the water than using chlorine and experiencing its side effects.


What a UV water filter can’t do


A UV water filter’s sole purpose is to eliminate microorganisms such as bacteria, viruses, parasites, algae, mold, etc.


It’s not made to eliminate man-made pollutants, sediment, metal, chemicals, hard minerals, or chlorine. This is an important fact to take note of in case you were considering the purchase of a UV filter for those purposes.


It’s also worthy to note that a UV water filter won’t be able to soften hard water. Moreover, if you have hard water, the total dissolved solids inside of it might block the UV rays from reaching the microorganisms’ DNA and eliminating them. As such, you’ll need to pair your UV filter with a reliable water descaler.

Why the Yarna UV water filter is better


We have seen how classic UV water filters function and have made it our mission to improve upon their classic design as much as we could.


Therefore, we have adjusted the way our model functions to make it much more efficient than any other UV filter currently on the market. Search for any other similar device and you will see that they all look pretty much the same.


The Yarna UV filter, on the other hand, is shaped in such a way that it exposes water to the UV-C rays for a prolonged period of time, thus increasing the number of microorganisms that it can eliminate. This is because we have made a spiral pipe through which the water flows.


The spiral pipe surrounds the UV-C lamp with a quartz tube, so the water has more exposure time to the rays. Even better, the entire system is surrounded by a carbon fiber enclosure that’s lighter than stainless steel and protects the components far better from dropping, strikes, and rust.


You can also check if the filter works properly by looking at the end of the tube. On the side of the YARNA UV13C model, there is a semi-transparent plastic cover where the ultraviolet light can be spotted. If the lamp is broken for any reason, the sidelight will not be visible throw the cover.

Benefits and Comparison With Other Models


There are a couple of reasons why the Yarna UV13C water filter is better than regular models. As we said earlier, we have made it our mission to improve on the classic design as much as possible to bring innovation and increase reliability while still maintaining an affordable price and energy consumption rate.


SpiralLight Technology


Regular UV water filters use a straight bulb with a straight pipe through which the water flows. With that said, water travels too fast for them to be anywhere nearly as efficient as the SpiralLight technology is.


Because of the way the water pipe is shaped, it allows for it to be exposed to the UV-C rays for 5 seconds when choosing the UV13C model, and for 7.5 seconds when choosing the UV18C model. Speaking of the two models, right from the name alone you can probably guess which one supports 13 GPM and 18 GPM. In any case, whichever one you choose, the water gets treated much more efficiently.


Carbon Fiber Enclosure


When compared to stainless steel, carbon fiber is just (if not even more) resilient. Because of this, you’ll have an easier time installing it and you’ll no longer have to worry about leaky gaskets or corrosion. Also, carbon fiber has a purifying effect, much like active carbon filters. With that said, dust is far less likely to settle on the UV bulb and affect the filter’s performance.




Unlike a RO system or other filtration methods, the Yarna UV water filter only requires you to change the UV lamp once per year. No gasket replacement, no fiddling with membranes or other components is required.

Other considerations


You might worry that you need to call a plumbing expert to install the UV13C or the UV18C. Far from it.


With the help of our comprehensive manual, you’ll be able to install it on your own without much more than what already comes inside the box. Other than that, just a little patience and care will do the trick.


Furthermore, it works on any type of pipe, so you don’t need to worry about that either. Also, our water descaler comes with the same benefit so you can pair the two flawlessly without modifying your plumbing system in the slightest.

How pairing a UV filter with a descaler can further enhance your water


So we’ve talked about all the benefits that a UV water filter can give you. Now let’s focus on some of the things that a water descaler can do to make your life a little more convenient.


What you first need to understand is that a water descaler is not a water softener. Instead of using salt packs to remove calcium and magnesium particles, a water descaler uses capacitive electronic signals to alter the hard minerals’ shape and make them less sticky. As such, no chemicals are added to your water supply.


And because mineral crystals get reshaped, your water will be clear enough to let the filter’s UV-C rays act directly on the targeted microorganisms. But the benefits don’t end there. Since you’ll no longer have to deal with sticky hard minerals, you’ll no longer be affected by hard water’s negative effects.


That means you’ll no longer need to use more cleaning products or deal with dermatitis and hair loss. Your hair and skin will feel much better and you’ll be able to take shorter showers while achieving the same results.


However, you’ll still enjoy the positives of hard water, such as more calcium and magnesium intake, which directly help you alleviate some of diabetes’ effects, as well as improve your overall health. By doing so, you’ll inevitably notice an increase in the quality of the water’s taste and smell as well.


What type of filter should you consider alongside the UV one?


To put everything we’ve talked about shortly, a UV water filter only eliminates living organisms like bacteria, viruses, and parasites.


If your water supply is polluted by non-living waste, you should get a pre-filtering system that can actively trap said pollutants before they reach the water supply that goes through the descaler and the UV filter respectively.


Considering that there are so many types of water filters, it might hard to find the one that’s right for your needs. However, we will try our best to describe what each filter type is meant to remove so that you can make a better purchasing decision.


Note: the best way to determine what pollutants are in your water is by testing it yourself with several types of test kits or, preferably, calling an authorized agency to collect samples and test it in the lab.


Activated carbon filtration


One of the most common types of filters are activated carbon models. We recommend it for the removal of chlorine, organic substances, chemicals, and sediment.


The downside of such a filtration method is that the filter needs to be replaced often. Also, you’re limited by the GPG because if the water flows too fast it won’t have time to trap all the pollutants.


This is the most common type of filter and often used in conjunction with other filtration methods for maximum toxin removal.


Ion exchange


Is your water source contaminated with radioactive materials? Then you might want to consider an ion exchange filtration method.


However, this type of filter has a major flaw: it’s only good for hard water and radioactive materials. So unless you live near a nuclear power plant, chances are it won’t do you much good. And, just like a water softener, it replaces minerals with sodium ions, which makes the water somewhat dangerous to drink and can greatly affect your septic system.


Mechanical filters


Most often used as pre-filtration methods, mechanical filters are reliable against physical particles and waste matter.


As for what exactly they filter, it depends on the type of material that they use to trap said waste and particles. Most often you will find models that use nylon floss, synthetic foam, or pads. Manufacturers are obligated to state what types of pollutants these will filter, so you will know exactly what you’ll be getting with your purchase.




We’re aware that there also exist water filter pitchers, shower filters, countertop filters, and many other types of filters that might satisfy your needs.


However, as mentioned earlier, the filtration process needs to take place before the water reaches the descaler and the UV filter. Thus, those won’t do you any good unless you want an extra layer of protection apart from what you get from the existing system.


Do I still need a UV water filter even if there were no bacteria detected during testing?


Yes, because bacteria and parasites can appear when you least expect them. Whenever an E. Coli outbreak took place, nobody expected it because no pathogens were detected beforehand. It happened because the municipal water plant screwed up or because the city’s water supply came in contact with feces thanks to a broken sewage pipe.


Final thoughts


A UV water filter is a necessity in any home, regardless of where you live or what other pollutants you might have in your water supply.


As long as you get a reliable pre-filtering system and a descaler in case you have hard water, the UV filter is your safest bet on keeping your water supply free from viruses, bacteria, and other potentially dangerous pathogens.
