Indoor air quality is a very important matter. We all spend up to 90% of our time indoors and mostly at home. We all need clean, fresh, pure and non-contaminated indoor air for healthy life today and for our future.
According to the E.P.A., indoor air pollution levels are as much as five times higher than outdoors because indoor air is far more concentrated with pollutants than outdoor air.
Poor indoor air quality does not only effect present health however some pollutants effect shows up years later and they can cause some very important diseases. When these particles are inhaled, they can affect the lungs, heart and blood stream. Once affected they can induce serious health problems, such as heart attacks, strokes, respiratory diseases, asthma and even cancer.
There are many varieties of airborne pollutants. We can separate them into 3 group:
1 – Gas form (i.e. Carbon monoxide, Nitrogen Dioxide, Radon, Formaldehyde, Volatile organic compounds)
2 – Particulate matter form (i.e. dust, pollen, pesticides, soot, smoke, asbestos, liquid droplets)
3 – Microbial contaminants form (i.e. mold, mildew, fungus, bacteria, viruses)
Some factors presence effect the pollutants amount in the air. Like a temperature level, humidity level, poor ventilation, poor filtration and poor purification.
If you want quality air, for the positive outcome, you should do some steps right.
First step: Good Ventilation.
This is an important part of maintaining good indoor air quality because there is no better therapy for human lungs and healthy body system other than fresh air. Every tight structure homes generates both moisture and pollutants. Mechanic ventilators HRV’s (Heat Recovery Ventilation ) and ERV’s (Energy Recovery Ventilation) fans pull fresh air into a home while simultaneously exhausting stale air from the home therefore they improving indoor air quality.
Everyone who does not have mechanic ventilator in their homes, they should ask themselves this question:
“ If I do not drink dirty water, why would I breath into dirty air ? ”
Second step: Filtration.
Our target in this step is to eliminate the maximum amount of particle airborne matter and stop the harmful effects. Particulate matters can be organic or inorganic and can be different size or shape.
According to the E.P.A., particulate pollutions have two important categories.
1-) Size of particles between 2.5 micrometer to 10 micrometer are called “ Inhalable coarse particles”,
2-) Size of particles up to 2.5 micrometers are called “Fine particles”.
Some particles, such as dust, dirt, soot, or smoke can be large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.
Ventilation and filtration are intended to remove or dilute pollutants and to control the thermal environment and humidity in buildings.
Third step: Humidity Control.
No matter if you have low or high humidity in your home, both are considered to be bad indoor air quality.
Proper humidity level provide you healthy life and saves your house againts the humidity related building structure problems. A humidifier, dehumidifier or a mechanical ventilator ERV will help you to have wonderful indoor air quality.
Please do not forget, if you can’t control humidity levels, you can’t stop the growth of life threatening mold, mildew and fungus in your home.
Fourth step: Purification.
An air purifier is a device which removes airborne pollutants in indoor air and they help to relieve your respiratory system. Most air purifiers contain air filters. Air filters are designed to collect particulate from the air. They have different technology, specific types and sizes .
Most common one is HEPA filters (High -Efficiency Particles Arrestance) with 99.97% efficiency. But many viruses bacteria and molds still pass through filters.
The only way to eliminate a big percentage of germs and bacteria from the air is by using the U.V. rays technology.
