The KDF and Chlorgon filtration media contained within the filters removes;

• Free Chlorine
• Combined Chlorine
• Hydrogen Sulfide
• Iron oxide (rust) and some other heavy metals
• Coarse Dirt and sediment
• Odours

They also pH balance the water between 7 and 7.3 if the pH is low. To give added quality assurance the filters have been NSF Certified to Standard #177 for free chlorine removal.

Parts of our filtration media are thin and brittle, meaning they can break down into smaller pieces through the mixing process, transport and use. It’s not uncommon to notice that some of the fines have escaped through the filter cartridge screen; this is normal, harmless and not a faulty filter. This is also more noticeable if you reverse the filter cartridges more often.

Free chlorine is converted to harmless chloride (salt) as it passes through the filter. Iron oxide or rust/ brown water on the other hand deposits onto the filtration media, where it will remain until the next shower. It is recommended to flush or run the shower filter with warm water for a minute or two at the beginning of each shower to “reset” the media and flush away the ions. If there is a high concentration of iron oxide in your water, a whole of house filtration system designed specifically for iron removal may best suit your needs.

The filters are NSF Certified (Contact Aqua Safe for details on manufacturer & certification) to standard #177 for shower filtration. This is considerably higher standard than NSF Certified Filtration Media.

This depends upon how you measure the chlorine levels and if you have a high quality filter. To test whether a shower filter is working or not, you need to measure free chlorine level not total or combined chlorine levels. For this you need to use a common DPD test kit or similar not and OTO kit as these test combined chlorine. Shower filters cause free chlorine to combine and become a harmless salt which affects the combined or total chlorine levels.
