Columbus Homeowners, Neighbors and Friends

Today more than ever, we are concerned about our indoor air quality. Our daily reality has changed, and we are spending more time in our homes than ever before. The air we breathe in our homes can harbor more than 30 million air pollutants per cubic foot, including viruses, we can say that the air we breathe in our home has five times more pollutants than the air outside. These can trigger all kinds of health problems, including asthma and allergies.     

We eat healthy foods, drink clean water, practice good hygiene, get plenty of sleep, and exercise. But what about the air we breathe?  

Breathe a sigh of relief, because help is on the way. We can help with your indoor air quality. Here is how:
1. By controlling the humidity in your home with a humidifier or a dehumidifier.
2. Decrease stagnant indoor air pollution with a whole-home-purifier.
3. Reducing the concentration of pollutants in your home with a ventilation system.
