Hello all! Welcome back to my blog. We have a furnace-mounted Aprilaire that was already here when we purchased this home 3 years ago. Yay.
There are several benefits to having a humidifier. Extreme dryness from winter heating can aggravate respiratory infections. It can also dry out your wood furniture and flooring. And, lastly, humidity in the air will increase the feeling of warmth, therefore you won’t set your thermostat as high. I had a humidifier put on the furnace at my last house several years ago, and can tell you from experience that they increase your overall physical comfort (and reduce snoring!)
There are 2 kinds of humidifiers – a drum style and a drip style. A drum style requires monthly cleaning while in use. A drip style requires annual cleaning. The one we have now is a drip style.
Furnace humidifiers have a humidistat which controls the humidity in your home. Typically most homes should use between 30% to 45% humidity level. Check with your manufacturer’s instructions on how to operate it.
Before cleaning make sure your furnace and water inlet are turned off. Remove the cover. The filter, or ‘evaporator pad’, can be removed after popping out the housing. Yep, we’re ready for a new one.
We replaced it just by sliding in a new one. They’re relatively inexpensive at $10 to $15.
Then pop the housing back in, and replace the cover. Once ‘furnace season’ gets rolling, we’ll check the evaporator pad occasionally to make sure it isn’t accumulating a lot of lime or calcium. If it is, we’ll clean with vinegar or a calcium remover. It will depend on how severe our winter is and how often the furnace is running. If you have a drum humidifier, you have to remove the parts and clean them monthly because the water pan can breed bacteria.
