Aside from these popular filtration methods, there are also other techniques such as distillation, which involves boiling tap water and then condensing it into a separate vessel to help remove contaminants like chloramines. Each method offers its own advantages and limitations, so it’s important for consumers to explore these options and determine which one best suits their needs and household requirements.

What is Chloramine and Why is it Used

Chloramine Vs Chlorine

Chloramine is a chemical compound that is often used to disinfect tap water in municipalities. It is formed when ammonia is added to chlorine. Compared to chlorine, chloramine is a more stable substance and offers some advantages when used as a disinfectant in municipal water systems.

Chlorine has been the traditional primary disinfectant used for water treatment mainly due to its effectiveness against bacteria and low cost. However, chlorine is volatile and evaporates readily, which makes it less effective as water moves through distribution pipes.


One key advantage of chloramine over chlorine is its enhanced disinfection capabilities. Chloramine acts as a secondary disinfection method that ensures the water remains free from bacteria and other contaminants as it travels through pipes to consumers.

In order to remove the chlorine, the chloramine must be deconstructed into its basic parts – chlorine and ammonia. Most tap water conditioners will break the chemical bond between the two elements and then destroy the chlorine, leaving the ammonia in the water.


The Environmental Protection Agency (EPA) regulates the use of chloramine in drinking water. Chloramines have been used by water utilities since the 1930s for disinfection purposes. It is important to note that chloramine is more cost-effective than chlorine, as it provides long-lasting disinfection.

When used in appropriate amounts, chloramine is safe for human consumption, and it also helps minimize the formation of disinfection byproducts that can be harmful to our health.

Here are some key points about chloramine:

  • A combination of ammonia and free chlorine
  • Used since the 1930s in water treatment
  • Provides longer-lasting disinfection compared to chlorine
  • More cost-effective than chlorine
  • Minimizes formation of harmful disinfection byproducts

Reverse osmosis (RO) systems are highly effective at removing both chlorine and chloramines from water. By forcing water through a semi-permeable membrane, these systems filter out contaminants, including chloramines, to deliver high-quality drinking water. RO systems can be installed under the sink or as whole-house filtration systems, depending on your needs and budget. Keep in mind that RO systems require periodic maintenance, including filter cartridge replacement, to ensure optimal performance.

Catalytic Carbon Filters

Catalytic carbon filters are specifically designed to reduce chloramines by up to 99%. These filters use a specialized type of activated carbon that facilitates chemical reactions to break down chloramines. Like activated carbon filters, catalytic carbon filters can be used in various systems, such as under-sink units or whole-house water filters. Ensure to replace the filter cartridges per the manufacturer’s recommendations to maintain their effectiveness.

Dechlorinating Products

Dechlorinating products, such as tap water conditioners, are commonly used by aquarium enthusiasts to remove chloramines from their tap water. These products are formulated to break the chemical bond between chlorine and ammonia, effectively dechlorinating the water. It’s essential to follow the manufacturer’s instructions when using these products to ensure proper chloramine removal.

By choosing from these methods, removing chloramines from your tap water can be simple and efficient. Consider using activated carbon filters, reverse osmosis systems, catalytic carbon filters, or dechlorinating products based on your specific needs and preferences to enjoy clean, chloramine-free water.
