Indoor Air Quality​

Keep your home safe and healthy with air purification technology that reduces airborne and surface contaminants, and pollutants.

Indoor Air Quality​

The indoor air quality in your home or office can be five times more polluted than outdoor air, primarily because indoor air is not properly sanitized. There are added contaminants that are simply not filtered out of the air, but instead accumulate over time in our modern, tightly sealed homes. This happens because bacteria, viruses, mold spores, and other toxins are too small to be captured by passive traditional air filters, and some can even pass through a HEPA filter.

So, since you spend up to 90% of your time indoors, it's important to consider the impact these pollutants can have on your long-term health. Luckily, you have found a company dedicated to solving indoor air quality problems in the most innovative and effective way possible.

Humidifiers and Dehumidifiers

Balance your home's humidity to help improve sleep and dry skin, enhance productivity, and keep you protected against airborne viruses. Additionally, AprilAire Humidifiers and Dehumidifiers help preserve your home and any contents susceptible to cracking and warping due to low humidity levels. While balanced humidity exists between 40 and 60%, it's important to remember that outdoor temperature and other home factors will impact what relative humidity level is attainable and recommended for your house.​
