Air Purifiers

Indoor air quality is an important part of modern HVAC systems. Homes today are sealed tightly for energy conservation. However this in turn can recycle stale air, toxins, bacteria and mold throughout your home. Dial One Mears provides indoor air quality products that integrate into your HVAC system, and work together to purify and refresh your indoor air.
Air purifiers clean the air of harmful pollutants, such as dust, dander, pollen, chemicals, and odors. They work by pulling air through a series of filters, which cleans the air by trapping polluted particles. Then, the cleaned air is blown out by an electric fan. Although most units use only a filter process, there are some variations on air purifiers, such as the electrostatic plate units that trap particles within a magnetic field. These electrostatic units still employ filters at some stage.
Additionally, some air purifiers use carbon filters to absorb chemicals and odors. The absorption ability of a carbon filter is directly related to the size (thickness) of this filter (or the amount of loose carbon that is present in the filter). Most air purifiers utilize pre-filters as well. These pre-filters help to collect large particles, such as hair, dirt, and dust, to preserve the life of the HEPA filter, which is the heart of an air purifier. Quality HEPA filters are able to filter between 97%-99% of all particles from the air. They are constructed of durable, professional-grade material designed to last a specific amount of time, based on use and indoor air conditions.
