The indoor air quality in your home is probably quite a bit worse than you think it is. Sure, you may not be hacking and coughing every minute you spend inside, but that doesn’t mean that your air quality is as good as it could be. Poor air quality has substantial impact on the health and comfort of the home’s occupants. It can cause all kinds of issues, from allergy attacks, to the flu, to bouts of asthma. These issues are typically the result of exposure to microscopic contaminants. Common household air contaminants include, but are not limited to, dust, pollen, dander, viruses, bacteria, and mold spores. It’s a good idea to install a whole-house air filter to address these contaminants and improve your air quality. Before you do that, though, there are some things that you need to account for.
