Why Your Houses Indoor Air Quality is Important

The worldwide growth of COVID-19 has likely shifted your regular routine into a jumble.

In uncertain times, you can take peace in knowing your house is your safe retreat. You’re possibly spending lots more time there now. That’s why your indoor air quality is now more important than ever.

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

Modern houses are securely sealed, which is good for energy efficiency. But it also means your indoor air can be more contaminated than the air outside. In actuality, the Environmental Protection Agency (EPA) says it can be two to five times inferior than outdoors. This might be problematic, since the EPA has calculated we spend about 90% of our lifetime inside.

There are many of factors that can contribute to poor indoor air quality, such as cleaning products and air fresheners. These can lead to headaches and irritate allergies and asthma.

There are a few things you can do to better your air quality. Some solutions include improved air filters, an air purification system or an ultraviolet (UV) germicidal light.

Not certain which system is best for your residence? Our expert professionals can conduct an indoor air quality audit. We’ll test several areas that affect your air, like dust levels, VOCs and ventilation. Based off of the results, we can then recommend the best solution for your household’s distinctive needs.

Air Filtration

When looking at air filters, it’s essential to look at the MERV rating, or Minimum Efficiency Reporting Value. This gauges how efficiently it filters contaminants.

One of the most average and most economical filters, flat fiberglass filters, are rated between 1 and 4 on the MERV register. Pleated filters are a little bit better, graded between 8 and 12.

We recommend buying at least a MERV 13, like the HC13 Media Air Cleaner, for optimal outcome. This filter delivers clearer air while lowering energy consumption*.

High Efficiency Particulate Air (HEPA) filters are considered the best in air filtration, as they’re typically in use at in hospitals. They’re effective at capturing 99.97–99.99% of indoor pollutants, such as pollen, pet dander and smoke.

Regardless of whatever filter you choose, you can take comfort in knowing they’ve been thoroughly tested. They have the lowest airflow restriction you can buy, which keeps your HVAC equipment operating properly.

Air Purification

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

These powerful units can wipe out:

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

UV Germicidal Lights

A UV germicidal light is added within your comfort equipment. Its penetrating rays eradicate bacteria and mold within seconds.

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

This light also has an extra advantage for your heating and cooling unit. It can help it run for a longer period of time and operate more efficiently, as it keeps the internal components clean.

Our air quality engineers suggest using one of these lights with an enhanced filter, such as our Carbon Clean 16® Media Air Cleaner, for the greatest results. This filter provides industry-leading MERV 16 filtration plus carbon-coated fibers to catch particles in your home’s air. It does all of this without limiting your HVAC equipment’s airflow.

Whole-Home Humidifiers

Acquiring correct humidity in your residence may help keep your family healthy when it’s cold. It can help with sore throats, flaky skin and cracked lips, in addition to added cold weather annoyances.

If you don’t know what your house’s humidity percentage is, we’ll determine it when we complete your indoor air quality audit. While the range fluctuates based off of outdoor temperatures, HVAC experts typically advise keeping it between 40–60 percent.

You can achieve this optimum range by using a whole-home humidifier. This unit usually accompanies your furnace or air handler to provide optimum humidity across your home. Some units, like the Healthy Climate® Whole-Home Power Humidifier, contain a built-in fan to circulate humidity during the time your HVAC equipment isn’t operating.
