The Mountain Fresh Canada filter contains laboratory grade sediment filters and premium grade, organic coconut based granular activated carbon (infused with silver). Because of these high quality components, this filter is the best on the market for sediment and chemical removal. Simple maintenance will ensure that your Mountain Fresh unit remains functioning properly for years to come.
The first stage .4 micron filter is replaced when 1200 gallons has filtered through, an average of once a year in most commercial applications. The .4 micron filter will trap all dirt, rust and sediment.
The second stage .2 micron filter acts as a safety net should the .4 micron fail from overuse. These first two filters help keep sediment and particulate matter out of the third stage carbon filter thus maintaining its efficiency. This doubling of filters also ensures that cysts such as Beaver Fever and Cryptosporidium are removed. This filter can typically have over 6000 gallons pushed through before it is necessary to look at replacing it. This is contingent on the .4 micron filter being changed regularly.
The granular activated carbon filter should be changed when a colorimetric test (such as Orthotolidine or OTO) shows presence of chlorine. Our testing on municipally treated Calgary water showed approximately 6,300 gallons of water could be used before chlorine could be detected. For office use, this would be 10 years at 2 gal/day.
