Chloramine, although a more stable compound, contains a combination of chlorine and ammonia and is also used to control bacteria in water systems. Its harmful effects cause the same dangers as pure chlorine. The  Vitamin C shower filter can effectively neutralize both free chlorine and chloramines with near 100% efficiency. KDF & Activated Charcoal type shower filters cannot neutralize chloramines from your shower water under any circumstances.

Limitations of Using KDF (Kinetic Degradation Fluxion) Process Media Within a Shower Filter

• KDF filters cannot remove organic chemicals such as pesticides, disinfection byproducts, MTBE, chloramines, heavy metals, etc. Only moderate to high free chlorine reduction is to be expected within a shower filtration device.
• KDF filters must to be back washed periodically with hot water to remove insoluble contaminants. This method wastes many gallons of unusable hot water and there is no way to prevent dislodged pollutants from coming out later with the supposedly filtered water. Shower filter manufacturers that claim their devices do not require regular backwashing do so because they are fully aware that KDF within a shower filter does nothing other than to reduce free chlorine. Since no insoluble contaminants are actually trapped by the KDF media, there is simply no need to backwash the unit.
• KDF filters are dependent on water temperature. For every 25 degree rise in water temperature there is only a 4% increase in effectiveness for free chlorine removal. This is assuming there is 1 pound of KDF present at a bed depth of 3.5" with a flow rate not exceeding 3.0 gpm.
• KDF filters generally reduce water pressure and flow rate. At 2.5 gpm you can expect to see a 10 psi drop in your water pressure. At 3.0 gpm you can expect to see a 15 psi drop in your water pressure.
• KDF filters are vulnerable to the level of particulate matter present in the water. Sediment of this type can obstruct the surface of the KDF media rendering it even less effective for free chlorine removal.
• KDF process media produces hydroxyl radicals and hydrogen peroxide. Both of which have a higher oxidative potential than chlorine itself. These free radicals are potentially more harmful to healthy cells than is chlorine.
• The effectiveness of KDF to reduce free chlorine is directly proportional to the amount of contact time that can be maintained. Long contact time simply cannot be achieved in any shower filtration device.
• KDF filters are intended to be used as drinking water filters, not shower filters. They are in no way similar.

Limitations of AC (Activated Carbon) Within a Shower Filter

• AC filters actively promote the growth of bacteria within the warm, moist confines of the shower filter enclosure. AC is actually a food source for bacteria under these conditions.
• AC filters are totally ineffective in the presence of fast moving warm or hot water and will quickly break down. There is no logical reason to use AC within a shower filtration device. Drinking water filter manufacturers that use AC within their devices consistently warn users from running hot water through the unit. The same rule applies to shower filters as the AC used in both devices is identical.
• AC filters are adsorptive, meaning trace contaminants that manage to be trapped will adhere weakly to the surface of the carbon particles until capacity has been reached. Once this happens, the contaminants will be released back into the water stream. There is simply no method to determine when this will occur.
• AC filters require long contact time with the contaminants that are intended to be adsorbed. This combination of high shower water temperature, fast moving hot shower water and short contact time render AC totally useless in a shower filtration device.
