Most homeowners don’t realize how versatile their HVAC systems are. Sure, they cool and heat the air. But the A/C and heating systems are also capable of improving your indoor air quality. What’s more, the HVAC can also keep the relative humidity lower in your home so that you feel more comfortable in the summer.
Here’s how your HVAC system works for better air quality in your home.
Filtering the Air
When you change your system’s air filter, you may not be doing much to keep your IAQ clean if you’re using the cheap fiberglass type. These filters are only good for catching the largest particles and keeping them out of the workings of the HVAC. But a better quality, dense, pleated filter can catch much finer particles such as pollen, pet dander, dust and dust mites.
It’s always best to use a filter in the middle range rather than a cheap one or a high efficiency model. The latter can slow down air flow in the HVAC to the point where the equipment labors to clean the air. Using so-called HEPA (high efficiency particular air filters) filters requires that your system be modified radically to accommodate them.
Air filter manufacturers all have different methods of rating their filters, but if you go by the government’s MERV (minimum efficiency reporting value), you should look for a filter rated from MERV 8 to 12.
If you’re concerned with getting the air cleared of other, finer types of particles then you may need to opt for an air cleaning or purifying system. These can be whole home or portable, although the type installed in your HVAC system usually does a better job.
These systems are designed to capture different types of particles. For instance, a UVGI (ultraviolet germicidal irradiation) light will kill living organisms such as mold or mildew, while an activated charcoal filter will trap smoke, odors and volatile organic compounds (VOCs).
