Full flow bacteria filter for showers, water dispensers and faucets

Full protection against Legionella bacteria and other microorganisms in your tap water. Ideal for anyone who values their health and wants the cleanest, safest tap water coming out of their shower heads.

Räyn removes legionella & all bacteria from tap water

The need for safe water in the shower

Our tap water is home to millions of microorganisms. Not only are they swimming in the water that comes from public water supplies, they also take up residence in biofilms on the walls of your home’s pipes. Swiss researchers have shown that tap water can contain up to 6 million bacteria per liquid ounce. Many are harmless to us, but some can make us sick. These include legionella, pseudomonas, noroviruses, and amoebas.

Räyn filters remove all bacteria, parasites, and other microorganisms as well as 99% of the viruses from your tap water. These results have been confirmed by independent laboratory testing. Räyn filters use modern filtration systems that are extremely robust and impervious to pathogens.

Installation between the tap and your shower head

Simply screw the Räyn filter into place between the tap and the hose of your shower head. The high-flow modern membrane material doesn't reduces the flow of water through your shower so you can control the quality of your water and eliminate germs.

The Räyn filter housing is made of an elegant, anodized metal and any commercial shower head can be connected. Along with high filtering performance, Räyn is compact and not much bigger than the palm of your hand.

4 reasons to buy a Räyn water filter

1. Protect your immune system

You come into contact with lots of water during your life, especially when showering. After all, a hot shower is the perfect place to relax and take a deep breath. Who wants to worry about inhaling Legionella from the steam coming off the shower or getting infected with pseudomonas, which can cause severe pneumonia?

2. Quick fix against Legionella

Do you suspect that there are high legionella concentrations in the pipes of your apartment building, but your landlord or homeowners association is dragging its feet? Are the waterlines in your building so old that they really need to be replaced in their entirety? At least you can take control of your situation and ensure the quality of the water in your shower.

3. Medical technology for highest safety

The Räyn filter purifies the water by passing it through pores that are only a few millionths of a millimeter in diameter. The filters consist of high-purity material used in medical technology, the same that is used in dialysis and for sterile filtration of water in operating rooms.

4. Full flow, full bacteria-removal at point-of-use

Providing a very elegant and compact design, the Räyn is yet very powerful when it comes to filtration performance. A new Räyn produces up to 8 gpm in flow and a removal rate of 99,99999% for bacteria and parasites.
