You are almost half right about your Equal knowledge.
YES! Equal does use a special AirX Filtered valve core or Valve Stem Filter Extension.
That shouldn't be a big deal as they take the valve core out when changing tires anyway. And need to put one back in.
Now for the rest of the story.
EQUAL is a dry polymer particle product and it does NOT ABSORB water in any way.
Due to the fact that EQUAL is a plastic polymer granule, water or moisture will not change its composition.
Moisture that accumulates inside the tire will evaporate due to normal driving conditions and therefore is in contact with EQUAL for a very short time.
When Equal is in contact with large amounts of water, (to the point where it is actually floating freely), will do just that, float.
Equalizes imbalance constantly, regardless of changing "load forces" and other variables. Equal has the ability to adjust to any and all changes of vibration frequency or force variation.
Lead weights are stationary on the rim and cannot adapt to changes such as tread wear, variations in radial force and load force. Equal helps prevent alternate lug wear, "cupping" and "flat spotting".
Front & rear dual tires, plus different size tires. Can use a different amount of Equal to balance them. Use the Equal chart for the amount to use in your tires.
