Before you purchase a furnace humidifier, another of the things that you are going to have to consider is the maintenance that should be done on a monthly basis. You should make sure that you are aware of what it includes and if you would be able to take care of this yourself or if you are going to need to hire an expert.

  4. Remove the cover from the humidifier
  5. Remove the drum and inspect the pad for any mineral deposits that may have hardened.
  6. Take out the foam pad that is in the drum by removing any clips or fasteners that hold the center shaft in place and pulling the two parts of the drum apart.
  7. Make a solution of 1:3 water and vinegar or a commercial fluid for calcium removal on the foam pad. Soak it until all of the deposits have dissolved and repeat if required, but if the pad isn’t completely clean or if it is torn, then it would need to be replaced.
  8. Replace the new or cleaned pad and then replace the drum so you can check for the proper water level. Make sure to know what the proper level is if it isn’t marked, which can be found in the user manual.
  9. Turn on the humidifier’s water supply.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one. During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry. I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
