Why Your Houses Indoor Air Quality Matters

The global transmission of COVID-19 has likely turned your typical routine into a jumble.

When things feel uncertain, you can feel good in knowing your house is your safe area. You’re probably spending a lot more time there today. That’s why your indoor air quality is now more crucial than ever.

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

Modern residences are securely airtight, which is good for energy efficiency. But it also means your indoor air can be more polluted than the air outside. In fact, the Environmental Protection Agency (EPA) says it can be two to five times worse than outdoors. This could lead to issues, since the EPA estimates we spend about 90% of our days indoors.

There are lots of things that can cause poor indoor air quality, like cleaning products and air fresheners. These could create headaches and exasperate allergies and asthma.

There are a few actions you can take to enhance your air quality. Some options include improved air filters, an air purification system or an ultraviolet (UV) germicidal light.

Not certain which solution is a good fit for your home? Our skilled professionals can perform an indoor air quality audit. We’ll examine several areas that affect your air, such as dust levels, VOCs and ventilation. Based on the outcome, we can then suggest the ideal option for your household’s distinctive needs.

Air Filtration

When browsing air filters, it’s essential to look at the MERV rating, or Minimum Efficiency Reporting Value. This assesses how successfully it filters contaminants.

One of the most common and lowest priced filters, flat fiberglass filters, are graded between 1 and 4 on the MERV scale. Pleated filters are a little bit better, graded between 8 and 12.

We suggest installing at minimum a MERV 13, for instance, the HC13 Media Air Cleaner, for optimal outcome. This filter delivers fresher air while reducing energy needs*.

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

Whichever filter you choose, you can take comfort in knowing they’ve been fully checked over. They have the lowest airflow restriction you can buy, which keeps your HVAC equipment working properly.

Air Purification

Lennox® has some of the best air purification equipment you can purchase. PureAir™ S and Healthy Climate™ PureAir Air Purification Systems provide hospital-grade filtration while handling all kinds of indoor air contaminants.

These powerful systems can take care of:

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

UV Germicidal Lights

A UV germicidal light is placed on the inside of your heating and cooling unit. Its powerful rays eliminate bacteria and mold within seconds.

If your family suffers from allergies or asthma, this system can deliver much-desired relief. Especially if you reside in an extremely hot climate where bacteria and mold thrive.

This light also provides an extra perk for your HVAC unit. It can help it run for a greater period of time and run more efficiently, since it keeps the internal components clean.

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

Whole-Home Humidifiers

Getting balanced humidity in your home can help keep your loved ones in good health in the winter months. It can help with sore throats, itchy skin and cracked lips, among other cold weather bothers.

If you don’t know what your home’s humidity percentage is, we’ll figure that out while we perform your indoor air quality audit. While the range fluctuates based upon outdoor temperatures, HVAC pros typically suggest keeping it between 40–60 percent.

You can achieve this ideal range by installing a whole-home humidifier. This system usually works with your furnace or air handler to give the right level of humidity around your house. Some models, like the Healthy Climate® Whole-Home Power Humidifier, contain an included fan to circulate humidity when your comfort equipment isn’t running.

*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.
