Filterless Vs Filter Humidifiers

Filter humidifier: This works by boiling and drawing water to a unit near the fan by using the filter. The fan then expels the water in form of spray or water mist. They are considered to be the most used type for decades

Filter-less humidifier produces water mist by using sound variations of high frequency. These humidifiers generally discharge much gray or white dust compared to those having filters, the dusts are mainly mineral deposits of water. This is because it contains no filter for trapping the mineral deposits of water.

Another main difference between these two types of humidifier is the operational noise. In the filter humidifiers, the fan plays the most significant role so it is quite natural that they do make quite some noise but the absence of fans in most of the no filter humidifiers makes them operate quite silently.

How to Care For Your Humidifier

  • Endeavor to change the water often: Don’t allow dirts or deposits to develop inside your humidifiers. Empty the tanks, dry the inside surfaces and refill with clean water every day if possible. Although, make sure to unplug the unit first.
  • Use distilled or demineralised water: Distilled or demineralized water has a much lower mineral content compared with tap water. This is because tap water contains minerals that can create deposits that promote bacterial growth. When they are eventually released into the air, they often appear as white dust on your furniture or pose danger to the air you inhale.
  • Clean all parts of the humidifiers at least every three days with a 3 percent hydrogen peroxide solution available at pharmacies; or chlorine bleach as recommended by some manufacturers.
