If you’re unfamiliar with the terms, mesh size indicates the resin beads’ size. A finer mesh size means the beads are smaller, packed tighter, and offer more ion-exchange surface area. Overall, they are more efficient at water softening.
Fine mesh resin packs more densely than normal mesh resin, reducing the softener flow rate. Because of this, we are not huge fans of fine mesh and do not include it among our usual product offerings on our website.
Most consumers who inquire about fine mesh have been led to misbelieve that it is more efficient for iron reduction.
Another thing to remember: if you take a water softener that previously utilized normal resin and add fine mesh to it, you must ensure that the lower basket is also replaced simultaneously.
This basket contains slots proportional to the resin beads’ size. A basket with standard mesh resin will have no problem accommodating fine mesh resin.
