What is the static pressure of Desiccant air filters?
The static pressure is different for every air conditioning unit because the amount of the air intake vent that is covered by the Desiccant air filter is different. The rule is to not cover more than 50% to 60% of the air intake opening. If this rule is followed, there’s no change in the CFM (cubic feet per minute). Will Desiccant filters always save money on energy costs? No. If the air conditioning capacity is inadequate for the building, Desiccant filters will not save money on energy costs because the cost savings are achieved by moving up the thermostat. Air conditioning capacity is typically calculated assuming 80% building occupancy. If this is the case and the building is 100% occupied, a lot of times the occupants will complain that it’s not cool enough inside. Installation of Desiccant filters will result in the excess moisture being removed and the air feeling cooler and the occupants may say they now feel comfortable. However, since the thermostat wasn’t moved up, very litt
