Why Air Quality Matters

Believe it or not- the air quality throughout our homes is considered to be worse than the outside air. In fact, The Environmental Protection Agency (EPA) reported: “Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often 2 to 5 times higher than typical outdoor concentrations.”

This may come as a shock, especially to the individuals that make a conscious effort to keep their house clean. However, keeping a pulse on air quality is a tricky thing, besides changing air filters every couple of months. Most likely because we can’t see the problem.

What pollutants are affecting the quality of air in my home?

The problem of indoor air quality begins with a lack of knowledge. With that being said, here are five pollutants impacting the air quality of your home:

  • Dust pollen– Most dust comes inside your home from outdoors. Even if you are an avid duster, this chore tends to populate settled dust particles back into the air which can cause sinus irritation and allergies.
  • Radon – Radon is a radioactive gas that is emitted into the air via the breakdown of uranium in rock, soil, water, and air. Radon typically gets in your home from the ground-up, entering through cracks or holes found in the foundation of your home. Breathing in this chemical compound can result in numerous health problems including asthma, bronchitis, pneumonia, ear infections, and even lung cancer.
  • VOCs (Volatile organic compounds)– VOCs are chemicals released into the air as a gas typically found in common cleaning and household products. Paints, aerosol sprays, pesticides, and disinfectants are all examples of products that contain VOCs. Short term exposure to VOCs can cause dizziness, headaches, and irritation to the eyes and respiratory tract. Long term exposure to VOCs may include, nausea, fatigue, irritation to the ears, nose and throat, as well as, cancer and damage to the liver and kidneys.
  • Mold– Mold develops through excessive humidity, condensation and water leakage throughout a home. It can be difficult to determine if you have a mold problem, but if you’ve had a water leak, it’s not uncommon for issues with household mold to follow. One clue is the discoloration of walls, ceilings, or floors. Exposure to mold can cause coughing, sinus irritation, nasal congestion, and in some cases, skin irritation.
  • Cigarette smoke– Any type of smoking within a home is frowned upon but especially cigarette smoke due to thirdhand smoke. Thirdhand smoke refers to the particles within the cigarette smoke that lingers throughout your home for the long haul, sometimes years. Exposure to the residue known as thirdhand smoke can lead to respiratory issues like coughing, asthma, and respiratory tract infections

Without proper air circulation in the home, exposure to indoor air pollutants like the ones listed above, and their negative health effects, will be far more common.

What Is The Purpose Of An Air Purifier?

Air purifiers are designed to remove pollutants from the air that naturally come in your home regardless of how often you clean. Most air purifiers are constructed with true HEPA (High-Efficiency Particulate Air) filters, which are proven to collect 99.97 percent of airborne particles of 0.3 microns in size.

Air purifiers work by capturing particles that circulate through the air when they enter the machines air filter. For the filter to work properly, it’s extremely important to have consistent air flow, as well as a regular filter replacement. When you notice the filter is dirty, be sure to replace with a new one.

What’s The Difference Between An Air Purifier And A Humidifier?

An air purifier works to eliminate allergens and large particles in the air whereas a humidifier works to add humidity to the air to prevent dryness and irritation. Air purification and air moisture are both helpful for sleep. Learn more about the benefits of sleeping with a humidifier here.
