What is an air purifier?

An air purifier, also known as an air cleaner, is an appliance that helps in capturing the pollutants present in the indoor air and keeping it clean for you to breathe. They trap dust, dirt, viruses, bacteria, smoke, pet dander, pollen, mold spores, and other types of pollutants from the air. Air purifiers are especially beneficial for people who are suffering from asthma and/or allergies. There are four types of air purifiers based on the filtration methods namely, HEPA filtration, Ultraviolet (UV) lights, Carbon filtration, and Negative Ionization.

What is a humidifier?

A humidifier is an appliance or device that is used to increase the level of humidity in the indoor air. They can be used for increasing humidity in a single room or the entire house. Humidity level usually falls when we create artificial heating inside our house, which also gives rise to the level of dry air inside. Humidifiers increase humidity in a place and help get rid of the dry air and issues related to it. Low humidity can cause many health issues such as respiratory distress, damage to household items, and static electricity problems. The three types of humidifiers commonly used are cool mist, warm mist, and ultrasonic humidifiers.
