Filters are basically grilles that are generally placed just below the door at the air outlet. Found the filters need to be unblocked and cleaned. If the air conditioner consists of activated carbon, the spent ones will be removed and the still good ones washed with warm water.
If the unit has normal filters, they will be disassembled and dusted with a vacuum cleaner or rag. They will then be washed with mild soap and dried scrupulously with a cloth and allowed to air dry thoroughly on a clean shelf. The same steps should be taken for multi-zone air conditioning systems or centralized air conditioning systems with vents in various rooms of the house: filters should be washed well, system surfaces and vents cleaned.
Finally, for thorough air conditioning filter sanitization, specific sanitizing products will be used that act quickly on viruses, bacteria, fungi, mold and other germs pato
genes, as well as attacking and destroying odors.
