• Make your ducts leak–proof. Some ducts have UV lights to terminate microbial being that get into your room with the air.
• Keep you air conditioner on 24x7. This is because, besides cooling the air, the A/c also works to remove excess humidity from the room air.
• Keep your attic well ventilated with fans as it is one of the major quarters that foster mold growth. Check your crawl space and basement regularly for musty smell of molds.
• Dust is a great substrate for mold growth. Therefore vacuum your house daily and effectively to remove dust, pollen and other organic compounds. You should also vacuum certain parts of your air conditioner at regular intervals to keep them clean.
• You can use install UV air purifier in your HVAC. These use photo catalytic oxidation to kill germs. Photo catalytic oxidation (PCO) is carried out by using UV light rays and TiO2 (Titanium Oxide) coated filter. This oxidation process generates hydroxide radicals and super-oxide ions that are highly reactive electrons. This process can destroy volatile organic compounds (VOC’s), bacteria, mold and fungus. The air passes through photon light and a catalyst, made of specific Nano-sized mineral compounds. This exposure releases three specific free radicals which terminates the bio aerosols. They are - hydrogen peroxide, hydroxide radicals, and hydroxides attach themselves to specific organisms and kill them.
• Another mechanism used by UV air purifier is Ultraviolet germicidal irradiation (UVGI). It is a very popular method of killing airborne germs and bacteria. It can reduce almost 50% of aerial microorganism in 45 minutes. The device that uses this process emits UV rays of short-wavelength. The ultraviolet (UV-C) destroy the nucleic acids and disrupt DNA. This disables these organisms to perform vital cellular functions.
• Buy good-quality pleated air filter to prevent microscopic dust particulates from getting into the air handler and ducts.
