The main difference between bypass and fan-powered humidifiers is that the former uses the blower motor of a furnace to distribute moist air throughout the house. As a result, it can’t operate when the furnace is off, whereas a fan-powered humidifier can run on its own.
Although these two types of humidifer can already be distinguished from each other by this one difference in design, residential air conditioning and heating experts would advise you to go beyond this detail. To make an informed decision, compare them more thoroughly using the following factors:
Generally, fan-powered humidifiers are costlier than their bypass counterparts, although the price varies by model. The caveat when choosing a bypass unit is that it requires new ductwork; to link it to a furnace, a bypass duct installation is necessary.
Moreover, the operation and maintenance expenses associated with fan-powered humidifiers are usually higher. The built-in fan of these appliances causes them to consume more electricity, as well as break down more frequently if professional checkups aren’t routinely performed.
Bypass humidifiers are less efficient because the air they moisturize has to go through the furnace, resulting in humidity loss. Not only do they distribute less moist air throughout the house, they also use more water to prevent the water panel from getting clogged by mineral buildup.
Fan-powered humidifiers can more efficiently bring moisture in the air across more square footage. If you have a large space and live with many people, choosing a fan-powered humidifier over a bypass unit will deliver better results.
If you value peace and quiet, a bypass humidifier is for you. It has no fan, so it adds practically no additional noise to the running furnace. On the other hand, a fan-powered humidifier is definitely louder. The noise can be muffled, though, with soundproofing techniques like proper insulation.
