FAQs

Do You Need A Uv Filter For Well Water?

In certain areas, you find tap water is the available water, but it’s very dirty for consumption and drinking because of its water source, and people opt to filter it to make it safe and clean for drinking.

Some people also believe that rainwater is the cleanest and safest for drinking without knowing that the atmosphere is contaminated. Also, the gutter may not be clean enough; therefore, it is best to filter any water before drinking.

Therefore this question comes up because many filtration methods in the market can make water safe for drinking. I would recommend a UV filter if you are researching water filtration methods for the safest and cleanest water.

I would do that because the UV filter does not use any chemical additives in the disinfection process that may alter the natural taste of the water or odor. Also, the UV filter ensures that all the contaminants are eliminated through ultraviolet rays. When discussing contaminants, I mean Protozoa, bacteria, viruses, and other harmful microorganisms present in the water.

 If you care about protecting your health at all costs, then you need the UV water filter since it will give you 100% confidence when drinking water because you will have the certainty that all the contaminants are destroyed.

Do UV Water Filters Work?

People ask this question because of the fear of getting the opposite results after purchasing a UV water filter. However, you shouldn’t have to worry because the UV water filters work.

These filters use ultraviolet rays to eliminate all the viruses, bacteria, protozoa, fungi, and more. The ultraviolet rays’ maximum concentration destroys the DNA of these microorganisms by penetrating through their cell wall and scramble the nucleic acid of their  DNA hence preventing them from reproducing, making the water safe and clean for drinking.

However, it’s important to note that some bacteria and protozoa such as Cryptosporidium and Giardia, have a thick cell wall that any amount of UV may not destroy them; therefore, it’s best to use the highest amount of ultraviolet rays to ensure 99.99% destruction of the bacteria in the water; and also to ensure that the specific UV light sterilization system is designed for such bacteria and viruses for you to observe effective results.

Also, you should note that the UV water filter only destroys the bacteria and leaves them suspended in the water and also does not eliminate chemical contaminants.

Therefore, it’s best to go for a UV filter that uses reverse osmosis to eliminate the bacteria and filter out their dead bodies floating on water to achieve an effective water filtration process.

If not, you can add pre-filtration systems such as sediment filters and carbon filters that filter out water and make it clear before it undergoes a disinfection process that effectively destroys all the bacteria present in the water hence making it safe and clean for drinking.

How Long Do Uv Water Filters Last?

During the purchase of a water filter, you may want to know the lifeline of the UV water filter to acquire value for your money. UV water filters may last for a long time due to good maintenance, but they have systems that should be replaced to work effectively.

 The UV filters have a UV lamp that concentrates the amount of light to eliminate bacteria; this lamp has a display of 9000hrs and should be replaced annually for the UV filter to function effectively. After one year, the UV lamp stops working effectively; that’s why it is replaced annually.

Also, in a UV water filter, it features a quartz sleeve that protects the UV lamp. During the filtration process, sediments and minerals may tend to build upon the quartz sleeve and cloud it. If not cleaned properly and regularly, the debris or sediments may inhibit light from penetrating and killing the microbes, allowing them to pass through.

Therefore it’s best to regularly clean and ensure its always clear for light penetration. Also, the sleeve should be replaced when it’s not clear enough to allow maximum light penetration to enhance the effective functioning of the UV water filter.

Furthermore, the UV water filters last for long, depending on how you maintain it. During the filtration process, it’s very important to maintain the added pre-filtration systems that filter out minerals and sediments such as the sediment filters and carbon filters. These filters should be changed after a certain period, and that’s by regularly monitoring the system to ensure that they’re all functioning properly.

How Long Does It Take For Uv Light To Sterilize?

During the disinfection process, the UV light destroys the bacteria DNA’s nucleic acid present in the water, depending on the effectiveness of the filter. You may be curious to know how long the UV light takes to sterilize the water.

The UV light sterilizes faster in 10 seconds if the distance to the bacteria is minimal, and there is the highest concentration of it. The distance of the light to the bacteria depends on how much time it takes to sterilize, and also the concentration of the light is a huge factor in sterilization time.

The higher the UV concentration, the faster the sterilization process, and vice versa. Also, the shorter the distance of the UV light to the bacteria, the faster the sterilization process and vice versa.

Therefore if you want to completely sterilize the harmful bacteria and viruses, its best to ensure that there is a maximum concentration of light by cleaning the quartz sleeve to ensure complete penetration of light. Furthermore, it’s best to replace the lamp annually to function properly and allow the UV light to sterilize the bacteria completely.

How Do You Tell If A Uv Filter Is Working?

We use a UV filter to eliminate all the bacteria and viruses present in the water to make it safe and clean for drinking. However, it’s very hard to know that your water is safe for drinking after filtration from just a look or an assumption.

Yes, contaminated water may appear cloudy, but that does not give 100% certainty that if the water is clear it is free from bacteria, protozoa, and viruses. Therefore we tend to ask this question to have that satisfaction that the product is working effectively and worth the value for our money.

For you to know if your UV filter is working can be done by checking the lamp if it’s glowing, and if it isn’t, there may be a problem with the lamp, ballast, or just electric problems that can be fixed.

You may also check the bulb if it’s functioning well to radiate the UV rays that destroy the bacteria. It can be done by using a white piece of cloth or paper where you hold it against the light, and if it turns a violet shade, that means its working, and if it remains white, that means that the filter is not working and the water is still contaminated.
