Air Filtration

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

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

We recommend buying at minimum a MERV 13, for instance, the HC13 Media Air Cleaner, for the most ideal effect. This filter provides fresher air while reducing energy use*.

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

Whatever filter you choose, you can take comfort in knowing they’ve been fully tested. They have the lowest airflow restriction you can buy, which keeps your HVAC system operating smoothly.

UV Germicidal Lights

A UV germicidal light is installed inside your HVAC equipment. Its penetrating rays wipe out bacteria and mold within seconds.

If your family has allergies or asthma, this equipment might deliver much-desired relief. Especially if you live in a humid climate where bacteria and mold flourish.

This light also has an added perk for your comfort system. It may help it work longer and heat and cool more efficiently, since it keeps the internal components clean.

Our air quality engineers suggest installing one of these lights with an enhanced filter, such as our Carbon Clean 16® Media Air Cleaner, for optimal outcome. This filter provides industry-leading MERV 16 filtration plus carbon-coated fibers to remove particles from your home’s air. It completes this without limiting your HVAC equipment’s airflow.

Whole-Home Humidifiers

Getting correct humidity in your residence can help keep your household healthy during the winter. It can aid sore throats, dry skin and cracked lips, amidst other cold weather annoyances.

If you don’t know what your home’s humidity percentage is, we’ll measure it when we complete your indoor air quality audit. While the range changes based on outdoor temperatures, HVAC experts typically suggest keeping it between 40–60 percent.

You can accomplish this optimum range by installing a whole-home humidifier. This system generally accompanies your furnace or air handler to give optimal humidity throughout your house. Some units, like the Healthy Climate® Whole-Home Power Humidifier, use an included fan to move humidity during the time your heating unit isn’t operating.
