“Due to excessive indoor pollution, the heating, ventilation, and air-conditioning (HVAC) system may run into some problems, such as clogged ductwork and filters. For those suffering from indoor allergies, this could lead to symptoms like sinus congestion, sore throat, and asthma. Fortunately, a reputable home allergy relief supplier, such as the Allergy Relief Store, offers allergy relief products like furnace and air conditioning filters.
Allergens, such as mold and dust mites, can circulate throughout the house by way of malfunctioning HVAC systems. On the bright side, indoor pollution can be significantly reduced by replacing existing filters with more effective models. According to Dreeszen, high efficiency furnace filters capture thirty times more allergens, and homeowners are advised to always keep their furnace fans switched on for maximum efficiency. “
