Bacteria and viruses in water can potentially affect humans during showering, though it’s generally less likely than through ingestion. These microorganisms can enter the body through the eyes, nose, mouth, or wounds. However, in developed countries, water is usually treated to kill such pathogens before it reaches your home, reducing this risk significantly.
These concerns make us worry about the quality of shower water. Hence, it is important to know how to remove them. Many people ask whether a shower filter can remove bacteria and viruses. Is a shower filter good enough to make water fit for showering?
This article answers all your concerns.
Can a Shower Filter Remove Bacteria & Viruses?
Shower filters are primarily designed to reduce chemicals, like chlorine and minerals, that affect water hardness, but they typically don’t eliminate bacteria and viruses. More advanced water treatment technologies like ultrafiltration, ultraviolet (UV) light, or reverse osmosis systems are needed, usually part of whole-home water filtration systems rather than standalone shower filters.
You’ll be surprised that some shower filters are designed to prevent bacterial and mold growth inside the shower. These filters are made with KDF-55 media and/or nano-silver technology to prevent bacterial mold. It ensures that a shower filter doesn’t affect water quality negatively.
Best Ways to Remove Bacteria from Water
This is the simplest and most accessible method to kill bacteria in water. Boiling water for at least one minute can eliminate harmful bacteria, viruses, and parasites.
This involves adding chlorine to the water. Chlorine is highly effective at killing bacteria and viruses. However, it can leave residual taste and odor and produce potentially harmful by-products.
Ultraviolet (UV) Treatment
UV light can kill bacteria and viruses effectively without adding chemicals to the water. The water must be clear for this method to be effective, as the light must reach the pathogens.
Reverse Osmosis (RO)
RO systems force water through a semi-permeable membrane, removing many contaminants, including bacteria and viruses. They are typically installed under the sink and require a certain amount of water pressure to function effectively.
This involves heating water until it turns to steam and then cooling the steam back into liquid in a separate container. This method kills bacteria and removes other contaminants but can be energy-intensive and slow.
What kind of Bacteria can you find in Water?
In water, one can find a variety of bacteria, including both naturally occurring and potentially harmful types. Some common types include E. coli (often indicative of fecal contamination), Legionella (which can cause Legionnaires’ disease), and Pseudomonas aeruginosa (a common cause of infections, especially in people with weakened immune systems).
Are all Bacteria in Water Harmful?
No, not all bacteria in the water are harmful. Many bacteria are naturally occurring and pose no threat to human health. Some bacteria are even beneficial and play essential roles in ecosystems, such as aiding in nutrient cycling. However, certain bacteria, like those mentioned above, can cause diseases when ingested or come into contact with the body.
