Those who are looking for an answer to the question «Why can a porcelain filter catch all bacteria but viruses go through?» often ask the following questions:

❔ Do air purifiers filter and kill viruses and bacteria?

Air purifiers remove viruses and bacteria by trapping them on their filters or even destroying them. Ultraviolet bulbs, ionizers or special coatings on the filters ensure complete decimation of pathogens. If these features are not present in your air purifier then the filter surface can itself become a source of secondary pollution.

❔ Water purification from bacteria & viruses?

Some common bacteria and viruses present in the water supply include Cholera, E. Coli, Giardia and Cryptosporidium. Needless to say, these bacteria cause serious health problems and diseases. You don’t even want to go into the details of the health problems they cause. Fortunately, municipal water treatment plants kill these harmful bacteria by using Chlorine, which is a powerful disinfectant. However, this does not mean that our household water supply is completely free from harmful bacteria. In fact, a very small amount of the dangerous bacteria might still remain in the water supply, but it’s considered to be “safe” according to government regulations. Private water supplies such as wells and lakes must be treated by the owners. When it comes to completely removing bacteria from water, an Ultraviolet Water Filter is the best solution. It is a great filtering system for people who receive municipal and private water. A UV Water Filter is proven to be the most effective way for killing bacteria and viruses in water. The way Ultraviolet Water Purifiers work is by releasing UV radiation into the water that runs through it. This Ultraviolet radiation has the same wavelength as some of the bacteria. The UV rays perfectly match the size of the bacteria. The UV radiation penetrates the cells of the bacteria, changes their DNA, and prevents the bacteria from multiplying. This effectively sterilizes or kills bacteria, as they are no longer able to reproduce and cause any threats. An Ultraviolet Water Purifier comes with a special sealed lamp that releases the radiation as water flows through a flow chamber or pipe. It connects to standard 120 - 240V electrical outlets for power. A great advantage of Ultraviolet Water Purifiers is that they are toxic free and don’t produce any new chemicals after filtering the water. This important characteristic makes Ultraviolet Water Purifiers very low maintenance purification systems. The special Ultraviolet Lamp has a limited life that lasts for about a year or slightly more. After that, the lamp must be replaced. Ultraviolet Water Purifiers come in a variety of sizes to accommodate different needs. There are large systems which are designed to serve an entire household and there are those designed for one specific fixture. It’s important to note that Ultraviolet Water Purifiers are the most effective products that kill bacteria. However, they are not effective for removing many other water contaminants. Therefore, Ultraviolet Water Purifiers usually make a great addition to water filters that remove most other harmful contaminants such as Chlorine, Arsenic, Hydrogen Sulfide, THM’s, VOC’s, and many others.
