Frequently Asked Questions

Q. "What is a micron rating?"
A. The average size of the openings between pieces of the filter media are represented in microns. For example, a 40-micron filter has larger openings than a 5-micron filter. Consequently, the 40-micron filter element will let larger particles pass through the filter than the 5-micron element.

As a general rule, the smaller micron rating for a filter is better, but as with most everything, there is a trade-off. Flow capability usually drops off as the micron rating gets smaller. To overcome this, low micron-rating filters must have larger elements to keep from sacrificing precious flow.

You may want to consider sediment filtration such as the Lakos sediment filtration system to remove larger particles, then possibly install a whole house water filter to take out smaller particles.

Another option might be to install a dual stage undercounter filtration system, which uses two filters with different micron ratings. The higher micron rating filter helps remove the larger particles from the water and prevents the smaller micron rating filter from getting clogged which would result in a reduced flow.
