Q. What is the difference between Chlorine and Chloramine?

A: Chlorine used to be the only chemical used to disinfect water, but now many water treatment plants have been switching to chloramines. Chloramines are chlorine plus ammonia.  Removing chlorine with a standard carbon cartridge is easy but Chloramines are not affected and require specialist catalytic grade carbons.  Chloramine removing carbon is much more expensive than ordinary carbon.

Q. How do I find out if my water has chlorine or chloramine?

A: If you are unsure what chemical is being used on your water supply we recommend contacting your water utility.  Alternatively, contact us here and we can consult our database to see if we have your utility listed.  NOTE: Some water plants use both chemicals and switch during the year according to the season.  Chloramines in summer and Chlorine in winter.

Q. I am unable to get an answer from my water utility. What should I do?

A: If you are unable to find out if you are on chlorine or chloramine we recommend you choosing a Chloramine cartridge pack as this type of advanced carbon will remove both Chlorine and Chloramine.

Q. What is the difference between Nominal and Absolute filtration?

A: Most filters micron ratings are Nominal.  This means that the cartridge will remove >99.9% of particles of particles at the micron rating specified. An Absolute rated cartridge is tested to remove >99.99% of particles at the micron rating of the cartridge and 100% of particles rated at 200% of the micron rating.
