It’s widely accepted that the indoor air in your home is as much as five times more polluted than clean, outside air. What pollutants are found in indoor air, where do they come from, and most importantly– how can you reduce or eliminate them?
Central Air Circulation
By design, central heating and air conditioning circulates the same air over and over inside of your home. Air is drawn into the cool air vents of your HVAC system, then the same cool air is heated or cooled depending on the season and pushed back out through your heating and cooling vents. The same air is circulated over and over. Unless some fresh, outside air is drawn into your home, the same dirty air continues to circulate over and over.
Dust and Pollen
It is no secret that dust accumulates in your home. If you don’t dust your solid surfaces occasionally, your home will definitely fail the white glove test. The dust doesn’t just settle on your floors, tabletops and bookcases; it also settles on your furniture, carpets, and curtains. The dust gets in from outside when your windows are open, when your pets come inside, and from your shoes and clothes. Seasonal pollen is usually included with the outside air duct, making its way inside. If anyone in your family is susceptible to allergies, they know when the pollen level is high.
With no fresh air, the same dirty air just keeps circulating and getting more concentrated, but fresh outside air introduces even more dust and pollen. There are solutions. The air filter in your central air system is the number one solution to improving indoor air quality. What is the best way to improve the purity of the air in your home? Use a good filter and change it often. Regular dusting and vacuuming will significantly improve your indoor air too.
Cleaning, Disinfecting, and Sanitizing Products
There is irony in that the products we use to clean, disinfect, and sanitize our home removes grime from surfaces but leaves volatile organic compounds (VOCs) in the air we breathe. Some of the products that release VOCs include furniture polish, dishwasher and laundry detergent, oven cleaners, toilet bowl cleaners, bleach, air fresheners, hair spray, and other personal care products.
Formaldehyde is a harsh human respiratory system irritant. Unfortunately, formaldehyde is present in most homes because it is found in building materials. There is no safe level of formaldehyde exposure, exposure should be reduced as much as possible.
Mold is a VOC that can cause health problems. It can grow in areas where there is excessive moisture. In your home, mold might be found in leaking pipes, roof and window leaks, and areas that have been flooded. An air conditioner or dehumidifier will help keep your humidity level low and reduce the risk of mold growth.
The VOCs can be removed with activated carbon air purifiers. The professional technicians at Semper Fi Heating & Cooling can install a REMO HALO air purifier in your ductwork that will capture the VOCs. Over years, your air ducts collect dust and dirt. Semper Fi can clean and seal your air ducts.
