Air Purifier for the Whole House

A whole house air purifier is a system that is installed in your home's HVAC (heating, ventilation, and air conditioning) system to clean and purify the air throughout your entire house. Unlike portable air purifiers that only clean the air in a single room, whole house air purifiers are designed to provide comprehensive air purification for every room in your home.

How Does a Whole House Air Purifier Work?

A whole house air purifier works by using a combination of filters and technologies to remove pollutants and contaminants from the air. The system is typically installed in the ductwork of your HVAC system, where it can capture pollutants as the air circulates through the system. The air is then cleaned and purified before being distributed back into your home.

The specific technologies used in whole house air purifiers can vary, but common features include:

• HEPA (High Efficiency Particulate Air) filters, which capture 99.97% of particles as small as 0.3 microns
• Activated carbon filters, which remove gases, odors, and chemicals from the air
• UV (Ultraviolet) light, which kills germs, bacteria, and viruses
• Ionization, which uses negative ions to attract and trap pollutants
