In-home air purification may not be on the top of your priority list, but it should be. The Environmental Protection Agency (EPA) has stated that "indoor air pollution is one of the top five most urgent environmental risks to the public." In fact, numerous studies have concluded that indoor air quality can be up to 5 times more harmful than outdoor air. For this reason, it is imperative to at least consider the possibility of using an air purification system in your home. While there are many types, all air purification systems can dramatically decrease the amount of allergens, dust, pollen, dust mite feces, and other harmful irritants in your home.

Media Filters

This is the simplest and most commonly found type of purification device. This type of system forces air through a filter, which can be made from various types of materials, such as paper, cotton, or other fibers. The filter then traps particles through size exclusion, removing them from the atmosphere inside your home.

Electronic Filters

Sometimes called Ionizers, these filters use charged electrical surfaces to generate electrically charged ions. The ions attach themselves to particles, which are then elecrostatically attracted to a charged collector plate, effectively removing the particle form the airstream. These systems can usually be found either with or without a fan.

Humidification

These systems are pretty self-explanatory. A filter is combined with a humidifier, allowing you to add needed humidity to your home. The benefit of humidification is that many bacteria and viruses can only exist or thrive in low-humidity environments. By increasing the humidity level in your home, you can effectively decrease the levels of harmful illness-causing agents in your home. Increased humidity can also help with allergies, asthma, and other respiratory problems.

Ultraviolet Filtration

These systems are sometimes referred to as UVGI systems, which stand for Ultraviolet germicidal irradiation. These systems are extremely effective at removing mold and bacteria. They work by neutralizing and destroying microorganisms found in the atmosphere, such as bacteria and viruses.

Contact your local HVAC service technician to help find which type of home air purification will be best for you and your home. Other factors to consider when choosing an air purification system include noise level, filter replacement frequency, building size, and health conditions and history.
