If you have residential well water, we recommend having an In-line Cartridge Filter, also called a Sediment Filter. It acts as a pre-filter to catch sediment and other particles before they can get to your faucets or your water treatment system.
There are two different sizes for filter housings:
Standard In-Line Cartridge Filter
If you have a Standard filter housing, the best filter for the average household is a standard 20 micron string filter. If you have very fine sediment, you can use a 10 or a 5 micron (the smaller the micron, the smaller the sediment particles it catches) but you may experience more pressure loss and need to replace your filter more often. There’s also a pleated filter option, but we have found string works the best.
Big Bertha In-Line Cartridge Filter (or Big Blue)
If you have a Big Bertha filter housing, or Big Blue, we recommend a Big Bertha 25/5 micron filter, which is a dual gradient filter. The 25 micron catches the larger particles/sediment, and the 5 micron catches the fine particles. You can also use a 20 micron string filter; those are very common as well. We recommend Big Bertha filters over Standard Filers because there is more surface area.
How long should the filter last?
Generally, your filter should last about 1-3 months. It’s better to replace the filter regularly, clean the housing with a little bleach, and create a nice clean environment to protect your plumbing and water treatment equipment from sediment.
Filter for Sulfur Odor
If you have a slight sulfur odor to your water, we recommend using a 10 micron carbon filter (for either Standard or Big Bertha) to absorb the odor. Change the filter when you smell the odor again. If you have to change the filter weekly, the odor may be too strong and you may need a separate Carbon System.
