SafeHome Duo4 Deep Furnace Filters – Chemical, gas, odor and allergen filtration!

Replace filter every 6-9 months. More frequent changes may be necessary due to a wide variety of circumstances that increase particulate and chemical pollutants, including the following:

• Pets
• High amounts of dust
• Painting or renovations
• Sanding
• High levels of outdoor pollution
• Burning candles or using air deodorizers

Many furnace filters only remove particles which only address one aspect of indoor air pollution. Gas levels inside our homes continue to rise due to the combination of sealing our homes for energy efficiency and modern materials used in everyday items, including furniture that emit formaldehyde and cleaning agents that emit volatile organic compounds such as benzene, a know carcinogen. Allergy and asthma symptoms, as well as long term health problems, are often caused or triggered by these common gases. Unhealthy levels of contaminates in our homes have cause the US EPA to rank the air in our homes as a greater health threat than outdoor pollution and water contamination. Since we spend most of our lives indoors, which are now more polluted than outdoors, it is necessary to address the removal of gases and chemicals from our indoor environment. A SafeHome filter is an effective, easy and affordable solution for removing chemicals, gases and allergens from the air inside your home. Designed for replacing 4 or 5" deep section filters used in air handlers or air furnaces.

To maximize the air cleaning efficiency of your whole house furnace filter it is recommended your HVAC system run as much as possible since no air cleaning occurs when it is off. Most experts agree a minimum run time of 8 to 12 hours daily is necessary to clean the air in your home (depending on air quality). Without the use of the AirCycler HVAC controller, your only choice to achieve this recommended run time is to switch your system to auto fan and it will run 24/7 or take the chance your heating or cooling demands will meet the 8 to 12 hour run time. By using the AirCycler controller you can choose the minutes each hour to run the fan regardless of your home's heating and cooling demands. Since the AirCycler can independently control the HVAC system's fan, you can set it to turn on every 20 to 30 minutes each hour to meet the recommended 8 to 12 hour run time. This saves you money and allows you to get efficient air cleaning from your furnace filter. AirCyler sold separately below.
