Electrostatic Filter Resistance Comparison

Electrostatic Filter Initial Resistance Comparison

The following table shows you how different filters stack up against one another. Remember, you want a filter that has the lowest initial resistance as is practical. As this number gets lower, your HVAC system spends less time and energy making you comfortable. It also means less stress on the mechanical components such as the motor and the fan. Note that only one company - Newtron Products - offers a built-in carbon monoxide detector at this time. I imagine the other filter companies will follow suit as soon as they can figure out a way around the patent. Click here for a list of how to contact some of the companies in the table.
