Air Purifiers Work by reducing the concentration of viruses, germs, and various pollutants in the air, such as dust, pollen, and allergens. Bacteria, germs, and viruses, including the current coronavirus, are not only found on surfaces but also in the air, especially in indoor environments, and can continue to float there for hours. For this reason, the use of an Air Purifier for Offices and Homes allows for a significant reduction in the concentration of these dangerous substances, generating healthy indoor air.
It should also be noted that it is particularly in warmer seasons or during heating periods that larger quantities of harmful substances form in the air, increasing the risks associated with their inhalation.
Pre-filter: The pre-filter is made of washable plastic and its function is to filter coarse dust particles larger than 5 microns, such as household dust and pollen. This pre-filter is washable and reusable, with replacement recommended once a year.
Formaldehyde Filter: this type of filter present on our Master HL 800 Plus Air Purifier contains Activated Carbon capable of removing odors, gases, and unwanted substances from the air, as well as cleaning the air of harmful formaldehyde in a very short time. The filter should be replaced when it becomes saturated, generally every 6 months in case of normal pollution, more frequently in case of cigarette smoke or strong odors.
High-efficiency HEPA filter: this filter is designed for filtering suspended materials such as airborne germs, smoke, and dust particles down to 1 µm with an efficiency of 99% or more. In combination with the optional HEPA H14 virus filter, it becomes capable of filtering particles with a diameter greater than 20 nanometers, including coronaviruses, bacterial molds, dust, allergens, and some other types of viruses.
Ionization: through the electrostatic charge released by the ions in the air, dust particles settle on surfaces instead of floating in the air, providing significant relief to those suffering from allergies. Furthermore, this system allows for the destruction of odor particles and other pollutants.
