  1. I have a well and a softener. Do I need a sediment pre-filter?
    MICRON recommends that a sediment whole-house pre-filter be installed before your softener to take filtering load off of your softener resin bed. The resin bed is designed to soften, not necessarily filter the water. Without a pre-filter, any dirt or sediment coming from your well will have to pass into the softener. Having a pre-filter keeps the resin bed cleaner. 25 to 50 micron filters do a good job.

  2. Will MICRON String Wound Filter Cartridges fit my 10” filter housing?
    MICRON's 2 ¼” and 2 ½” diameter filters are wound on a 9 27/32” long core and will fit most common 10” filter housings. We also manufacture 4 ½” diameter filters on the same 9 27/32” length core. These cartridges, however, fit only the larger diameter housings available from other fine filter manufacturers.

  3. Are MICRON's filter cartridges micron ratings nominal or absolute?
    MICRON's string wound filter cartridges are rated as nominal. A nominal rating means that about 80% of contaminant particles above the rating will be held within the filter. Absolute rated filters are generally reserved for bacteria protection applications.

  4. I do not have a well but have a "city water" supply. I do not have a softener. Should I still install a filter in my house?
    MICRON recommends that you install a whole-house filter in the incoming water supply line to your house. Even though the supply is relatively clean, you may notice that small sand particles may still collect in your faucet aerators. This sediment also passes through your water heater and may collect there as well which could cause premature failure of the heater.

  5. How do I know when the filter cartridge needs to be changed?
    The amount of sediment that is present in the incoming water supply can vary greatly from house to house, city to city, etc. Therefore, it is hard to predict how long a filter cartridge will function before it is time to change it. However, MICRON recommends that pressure gauges be installed just before and immediately after the filter housing so differences in pressure across the filter can be monitored. Typically, a filter cartridge needs to be replaced when the difference in pressure readings reaches about 15 PSI under full flow conditions.
