Do you know the danger of a hot steamy shower?

Do you know the danger of a hot steamy shower?
When your unfiltered drinking water is heated in a shower it is 3 x more toxic to your body than drinking it! Documented scientific studies conclude that taking hot showers is a health risk.
Medical studies suggest a link between absorption and inhalation of chlorine in the shower environment, with elevated risks for diseases such as renal cancer and serious illnesses (Harvard University Study 2012).
In the enclosed shower stall, chlorine and some dangerous heavy metals vaporise from the heated water where it is inhaled and these chemicals go directly into your blood stream.
To a lesser degree, dermal (through the skin) absorption also occurs. Chlorine has a drying effect on the skin and scalp, causing irritation and sensitivity.
Showering in chlorinated water may also cause pre-existing conditions, such as asthma and eczema, to become exacerbated.
I love your shower filters! I noticed a considerable difference in my skin after one use. After a lifetime of dry oily skin after the first time I used it I went a whole day without having oily skin! My skins feels beautiful thank you for a great product, saving up for the water filter next!

Filter cartridge
Great product . Stops dry skin from chlorine. Lovely Australian company to deal with - first class service

Love my shower filter.
I’ve been using this filter every year for several years and I always come back to Zazen filters. The company is the best and so are their products. Thank you all for making our water clean and safe.

Lovely clean water
Produces chlorine free clean water for showering and leaves hair and skin in much better condition. Makes cleaning the shower recess easier too.

great for my hair and skin
So easy to install. I no longer have to smell chlorine every time I shower. My skin is less dry and my scalp doesn't get itchy after washing my hair. Very glad I made this purchase.

Clean and simple!
So easy to instal and great to know we are protected from any nasties when we shower


Love this product
Defiantly does the job it claims. filters the water and no chemical smell. Thanks You!

Thank you
The lady in the office told me where to unscrew the shower so I could replace the cartridge. The previous one was well past it’s use by date but I could work out which section to unscrew and how. I followed the instructions and it was easy. Upon using the shower I could immediately tell the water was different from what it had been. Thank you Kazen Water. Sylvia

Shower Filter Cartridge
I love it. I can really feel the difference in the smell and taste of the water. Before putting the filter on, I could smell the strong smell of chlorine. I really like it.

Too easy!
This filter ticks all the boxes and is super quick and easy to install

This is my first annual replacement filter for hand held filter shower. I just love my handheld shower head and so easy to remove old and install replacement. Customer service were a very kind help with my query too.
