Most of us consider good health a top priority. We wouldn’t think of doing our cardio routine outdoors next to a factory spewing pollutants into the air. However, we don’t often think about indoor air quality. This benign neglect could put our health at risk. According to the federal Environmental Protection Agency, the air inside can be at minimum 2 to 5 times more polluted than outside.
That’s a good reason to consider an HVAC air purifier, or HVAC air filtration system.
An HVAC air purifier can help promote good health by improving air quality in your home and workplace. So, what exactly does a central air purifier do?
An HVAC air purifier = fresh air
While ordinary paper filters in many central HVAC systems help remove dust from the air, these basic filters do not remove tiny particles that can harm your health. Central air purification systems, which are installed in your ductwork, remove dust, mold, bacteria and viruses from the air circulated throughout your space by your HVAC system.
How you benefit from an HVAC air purifier
Is the installation of an HVAC air purifier worth it? If breathing clean air is a priority for you, then it certainly is. For allergy and asthma suffers and those with chronic respiratory problems, the installation of an air purifier should be an even stronger consideration.
Here are some of the things an HVAC air purifier can do for your home or business:
- Trap pet dander and other allergens
- Block dust mites/dust
- Trap bacteria and viruses to prevent the spread of germs and illnesses
- Remove dangerous volatile organic compounds from the air
- Neutralize smoke from your fireplace or from smoked tobacco products
- Remove unpleasant odors emanating from places like stoves, ovens and trash cans
When should you consider getting an HVAC air purifier?
Have you done your best to maintain a dust-free, clean environment but still suffer from allergies and other respiratory ailments? Consider installing an HVAC air purifier. If there is a smoker in the house, adding an HVAC air purifier would be a wise investment in your health.
Businesses using volatile organic compounds (VOCs) are prime candidates for an HVAC air purifier (such as salons, furniture refinishing businesses, print shops, dry cleaners and auto body repair shops). Just about any business where cleaning chemicals or printers are used, there will be VOCs in the air.
Types of HVAC air filtration systems
Not all air purifiers do the same thing. Here’s a primer on the different types to help you choose what’s right for your space.
One of the most common types of an HVAC air purifier system utilizes a heavy-duty HEPA (High Energy Particulate Air Filters) filter to trap the largest particles like dust. HEPA filters can trap more than 99-percent of airborne particles .3 microns and larger in size from entering your breathing space.
Carbon Activated Filters
A carbon activated filter is a good choice for VOC, smoke, and odor removal. These filters contain tiny absorbent pores to trap contaminants as they pass through the filter.
HVAC ultraviolet light air purifier
Ultraviolet technology is often used in conjunction with HEPA air purifiers. While the HEPA filter will capture larger particles, an HVAC ultraviolet air purifier can kill tiny microorganisms, such as bacteria, using rays of UV light.
Electrostatic air purifiers
Many HVAC air purifiers also contain electrostatic fields to capture microscopic particles as small as .1 micron in size, including viruses. Electrostatic air purifiers clean the air by using static electricity. An electrostatic charge is generated by air flowing through a network of static-prone fibers. The static charge traps airborne particles until the filter is washed.
Ionizing air purifiers
An ionizing air purifier introduces negatively-charged particles that attract positively-charged air pollutants. As the particles group together, they become too heavy and fall from the air and attach to surfaces.
Other air purification considerations
If your air purity concerns are confined to a small area, portable air purifiers are available to remove dust and vapor particles from the air near the unit. These standalone units are often used in businesses with air quality challenges in a particular area, such as in a salon.
If you suspect your HVAC system is not providing your home or business with optimal air quality, it is smart to invite an HVAC expert in to clean your system’s ductwork. Ducts can harbor all sorts of nasty stuff including dust, mold and mildew, which will hurt your air quality.

Maintain your HVAC air purifier
Maintenance is key to air purifier effectiveness. Many HVAC air purifier systems rely on filters. After a while, these filters become clogged with a variety of debris and contaminants, making them less effective. Replace disposable filters on a timely basis. Or, remove and hose down reusable filters regularly.
