Why Your Houses Indoor Air Quality Matters

The international growth of COVID-19 has likely shifted your daily calendar into a jumble.

When things feel uncertain, you can feel good in knowing your home is your safe retreat. You’re likely spending lots more time there now. Consequently your indoor air quality is now more crucial than ever.

Did you realize we can put in indoor air quality products in your home that provide hospital-grade filtration? These options can clear bacteria from your air, as well as allergens, odors and volatile organic compounds (VOCs).

Modern residences are firmly airtight, which is good for energy efficiency. But it also means your indoor air may be more contaminated than the air outside. In reality, the Environmental Protection Agency (EPA) says it can be two to five times worse than outdoors. This might cause a problem, since the EPA has calculated we spend about 90% of our days inside.

There are a lot of factors that can lead to poor indoor air quality, such as cleaning products and air fresheners. These may lead to headaches and exasperate allergies and asthma.

There’s a combination of actions you can take to better your air quality. Some options include upgraded air filters, an air purification system or an ultraviolet (UV) germicidal light.

Not sure which solution is right for your house? Our skilled professionals can perform an indoor air quality audit. We’ll examine several aspects that impact your air, such as dust levels, VOCs and ventilation. Based off of the results, we can then recommend the ideal choice for your home’s unique needs.

Air Filtration

When browsing air filters, you should review the MERV rating, or Minimum Efficiency Reporting Value. This measures how successfully it filters pollutants.

One of the most ordinary and lowest priced filters, flat fiberglass filters, rank between 1 and 4 on the MERV system. Pleated filters are slightly better, ranking between 8 and 12.

We recommend upgrading to at least a MERV 13, like the HC13 Media Air Cleaner, for the most ideal effect. This filter delivers clearer air while lowering energy needs*.

High Efficiency Particulate Air (HEPA) filters are regarded as the gold standard in air filtration, since they’re frequently installed in hospitals. They’re effective at trapping 99.97–99.99% of indoor pollutants, such as pollen, pet dander and smoke.

Whichever filter you pick, you can take comfort in knowing they’ve been fully tested. They have the lowest airflow restriction you can buy, which keeps your HVAC unit running smoothly.

Air Purification

Lennox® provides some of the most advanced air purification equipment you can purchase. PureAir™ S and Healthy Climate™ PureAir Air Purification Systems offer hospital-grade filtration while handling all types of indoor air contaminants.

This powerful equipment can wipe out:

  • 99.9% of allergens, like pollen, dust and pet dander
  • 95% of bacteria-sized particles, like ones that lead to strep throat
  • 50% of VOCs and odors within 24 hours

UV Germicidal Lights

A UV germicidal light is added within your heating and cooling unit. Its powerful rays eradicate bacteria and mold within seconds.

If your family has allergies or asthma, this unit may deliver much-needed relief. Especially if you live in an extremely hot climate where bacteria and mold grow quickly.

This light also offers an extra perk for your heating and cooling equipment. It may help it last longer and run more efficiently, as it keeps the internal parts clean.

Our air quality engineers suggest combining one of these lights with an upgraded filter, such as our Carbon Clean 16® Media Air Cleaner, for optimal outcome. This filter delivers industry-leading MERV 16 filtration combined with carbon-coated fibers to trap particles in your home’s air. It does all of this without restricting your HVAC unit’s airflow.

Whole-Home Humidifiers

Acquiring balanced humidity in your residence might help keep your household from getting sick when it’s cold. It can assist with sore throats, flaky skin and peeling lips, amidst added cold weather annoyances.

If you don’t know what your house’s humidity range is, we’ll determine it while we do your indoor air quality audit. While the range varies based on outdoor temperatures, HVAC professionals typically suggest keeping it between 40–60 percent.

You can reach this ideal range by using a whole-home humidifier. This unit usually accompanies your furnace or air handler to provide optimum humidity across your house. Some equipment, like the Healthy Climate® Whole-Home Power Humidifier, have an incorporated fan to circulate humidity during the time your heating unit isn’t operating.

*Based on in-duct testing that shows Healthy Climate® filters reduce airflow restriction. Greater restriction of airflow creates a greater load on a unit’s fan motor, increasing energy consumption.
