Why Your House’s Indoor Air Quality Matters

Mar 25, 2020Our Blogs0 comments

The international transmission of COVID-19 has likely shifted your regular schedule into a jumble.

In uncertain times, you can feel good in knowing your home is your safe area. You’re likely spending more time there nowadays. That’s why your indoor air quality is now more important than ever.

Were you aware we can install indoor air quality products in your residence that deliver hospital-grade filtration? These products can remove bacteria from your air, as well as allergens, odors and volatile organic compounds (VOCs).

Today’s houses are securely sealed, which is good for energy efficiency. But it also means your home’s air can be worse than the air outside. In fact, the EPA says it can be two to five times worse than outdoors. This may lead to issues, since we spend about 90% of our lifetime inside.

There are many things that can cause poor indoor air quality, including cleaning products and air fresheners. These could result in headaches and worsen allergies and asthma.

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

Not certain which solution is right for your house? Our expert pros can do an indoor air quality audit. Based on the outcome, we can then advise you on the most fitting choice for your family’s distinctive needs.

Keep on reading to find out more about the air quality solutions we provide.


Air Filtration

When comparing air filters, it’s essential to look at the MERV rating, or Minimum Efficiency Reporting Value. This measures how effectively it filters air.

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

We recommend getting no less than a MERV 13, such as the HC13 Media Air Cleaner, for optimal results. This filter delivers fresher air while lowering energy use*.

High Efficiency Particulate Air (HEPA) filters are deemed the benchmark in air filtration, since they’re usually used in hospitals. They’re effective at trapping 99.97–99.99% of indoor pollutants, including pollen, pet dander and smoke.

Air Purification

Lennox® provides some of the most advanced air purification systems you can buy. PureAir™ S and Healthy Climate™ PureAir Air Purification Systems offer hospital-grade filtration while managing all categories of indoor air contaminants.

These powerful systems can eliminate:

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

UV Germicidal Lights

A UV germicidal light is added inside your heating and cooling equipment. Its strong rays eradicate bacteria and mold within seconds.

If your family has allergies or asthma, this unit may deliver relief. Especially if you are in a muggy area where bacteria and mold flourish.

This light also has an added perk for your HVAC system. It can help it last for a longer period of time and run more efficiently, because it keeps the internal parts clean.

Our air quality engineers recommend using one of these lights with an enhanced filter, such as our Carbon Clean 16® Media Air Cleaner, for the best outcome. This filter provides industry-leading MERV 16 filtration in addition to carbon-coated fibers to trap particles in your residence’s air. It does all of this without decreasing your comfort system’s airflow.

Whole-Home Humidifiers

Having even humidity in your residence can help keep your loved ones in good health when it’s chilly. It can assist with sore throats, itchy skin and peeling lips, amidst other cold weather irritations.

If you aren’t aware of what your house’s humidity level is, we’ll figure that out while we perform your indoor air quality audit. While the range varies based upon outdoor temperatures, HVAC experts usually suggest keeping it between 40–60 percent.

You can reach this optimal range with a whole-home humidifier. This equipment usually accompanies your furnace or air handler to provide optimal humidity across your residence. Some units, like the Healthy Climate® Whole-Home Power Humidifier, use an incorporated fan to move humidity when your heating equipment isn’t on.
