Do you find it hard to focus when you are in your home? Do you suffer from allergies when spending a lot of time inside? Do you have a hard time falling asleep? All these things can be symptoms of poor air quality. The air we breathe can have a major effect on our health, and this generation spends a lot more time indoors than previous. Some things can make your air quality worse. Having pets and smoking indoors are two major culprits of poor air quality. If you have pets, you should vacuum regularly with a vacuum that is equipped with a HEPA filter to prevent the dander from being released back into the air. Airing out your home will also help, even though this should be avoided at times where there is a high pollen count. Replacing the filters in your ventilation system will also help improve your air quality.
