Experience : Hi, I am Nick, I purchased an Air Purifier, and Humidifier for my home, and I want to share the benefits of owning both appliances.

I know that there are some advantages to having an air purifier alone, but I wanted to tell you about the ones that I have personally found when owning one with a humidifier. For instance, not only does it help keep the air in your home cleaner. But it also keeps your skin clean! It is important for people with sensitive skin like myself because they can experience dryness if their skin isn't properly hydrated.
