Conversation about Humidex vs. Santa Fe continues here.
Humidex basically pulls air from the outside to bring into the home. This causes some pressure changes in the basement that draws air from the outside and the first floor. This actually switches the natural flow of the air in the home causing more moisture and humidity to possibly build up in the basement.
This can lead to more humidity and increased dampness, which in turn leads to increased run time and electricity cost to run air conditioners in the rest of the home. They say you can run it for pennies a day, when in reality you're throwing your cooling and heating costs right outside by increasing the amount you heat in the winter, and air condition in the summer. (these can also be vented directly out of the home via the fan of the humidex, so you're systems will run more. )
Santa Fe Dehumidifiers only deal with the moisture and air that currently exists in the basement. This allows the airflow of the home to continue uninterrupted and be added to with moisture free and filtered air from the basement.
Air naturally moves through soil, slowly through the foundation and into the basement. From there it naturally rises through the home, 1st floor, 2nd floor, and eventually through windows or the roof of the home. This is known as Stack Effect.
Since moisture naturally moves with the air through the foundation anyway, the Santa Fe is designed to deal with the moisture as it migrates into your basement. The Humidex doesn’t deal with the moisture level in the basement and in fact can actually increase the moisture and humidity to unsafe levels by bringing air from the outside.
Sadly Humidex has sparked many debates on the proper techniques in venting basements and crawlspaces and mostly because of negative results with the product.
Venting a basement or crawlspace isn’t recommended and can actually introduce more mold, humidity and moisture.
