A Guide to Indoor Air Quality


Published: October 8, 2015

How is the air quality in your home?



Did you know? One in five people in the United States either have allergies or asthma and 55% of people tested positive for at least one or more allergens.

Most, if not all, who are affected by allergies or asthma tend to go indoors to escape outdoor allergens, but little do they know allergy and asthma control begins in the home. Truth is, the air in your home is so airtight which makes it more polluted than the outside air. Animal dander, second-hand smoke, dirt, mold and dust mites are the leading cause of indoor allergies and the main indoor pollutants. Other pollutants can come from furniture, carpet cleaners, conventional cleaners, even a coat of paint on the wall. 

Indoor air pollutants can trigger numerous health issues including the following:
  • Sinusitis
  • Headache
  • Fatigue
  • Nausea
  • Rash
  • Nasal congestion
  • Sore throat
  • Itchy and watery eyes
People with weakened immune systems can see more serious side effects, such as bronchial infections and pneumonia. Medical professionals do have treatments for allergic reactions but these professional recommended reducing or eliminating exposure to allergens.

Here are 5 ways to reduce indoor allergen for a healthier home:
  1. Vacuum once or twice weekly. In high traffic areas, vacuum the spot several time to pick up dirt. Use a HEPA filter to avoid putting dust back into the air and use a damp cloth for dusting.

  2. Prevent animal dander. Keep your pet out of the bedroom and shut the door. Cover vents with dense material like cheesecloth. It’s best to have low-pile carpet or a bare floor since animal dander is sticky.

  3. Keep a healthy level of humidity. Mold and dust mites love moisture. Keeping your humidity at 30%-50% will keep allergens under control.

  4. Avoid mold spores. Reduce moisture in bathrooms or kitchen and other water areas in the home. Clean moldy surfaces and fix all leaks to prevent damp areas.

  5. Make your home a smoke-free zone. Cigarettes contain over 4,000 chemicals and because of that it is the highest contributor to indoor air pollution.
