Could your shower head be making your family ill? Studies show that a large proportion of household shower heads harbour dangerous levels of bacteria, including Legionella, the cause of Legionnaires' disease, and many other microbes linked to serious health conditions. The problem is not the water. It is the shower head itself. Traditional shower heads trap water in their spray plates after every use. That stagnant water, combined with warmth and plastic surfaces, creates ideal conditions for bacteria to multiply rapidly, ready to be inhaled as fine mist the next time you shower. More than just Legionella As reported by the BBC in October 2025, and backed by a growing body of scientific research, the bacteria found in household shower heads are linked to a far wider range of health conditions than most people realise. Lungs: Legionella bacteria causes Legionnaires' disease, a serious pneumonia with a 12% death rate, widely believed to be frequently misdiagnosed. The same bacteria causes Pontiac fever, a flu-like illness with a 95% attack rate that includes children. Hair and scalp: Malassezia restricta, a fungus found in shower heads, is a known cause of dandruff and folliculitis. Around half of all adults experience dandruff. The shower may be a contributing factor that has never been addressed. Eyes: Malassezia fungi can cause keratitis, a painful eye infection. Acanthamoeba, another organism found in shower water, can cause a condition that leads to permanent blindness. Contact lens wearers face a heightened risk. Ears: Pseudomonas aeruginosa, commonly found in shower environments, is a leading cause of swimmer's ear. If your family suffers recurring ear infections, the shower head may be the overlooked source. Stomach and digestive system: Mycobacterium avium subspecies paratuberculosis has been found in shower water and is linked in scientific research to Crohn's disease, affecting around 115,000 people in the UK. Skin: Malassezia is linked to skin infections, particularly following beauty treatments that break the skin barrier. Blood: Pseudomonas aeruginosa can enter the bloodstream and cause septicaemia, a life-threatening blood infection, particularly for anyone with a compromised immune system, open wounds, or recent surgery. The solution RefreshFlip is the first shower head designed from the ground up to address bacterial contamination at the source. After your shower, flip the spray plate open. It exposes the surface to air, drying out bacteria naturally and breaking the growth cycle. No chemicals. No specialist products. Just flip. It takes a few seconds. Do it fortnightly. When you go on holiday, leave the plate in the open position so bacteria cannot establish while the shower is not in use. Why trust Fereno?
