Improving Indoor Air Quality

Indoor air quality is a major concern in the winter as Minnesota winters are cold.

This means that you keep your windows closed for months on end, limiting airflow.

This limited flow of air from the outside means everyone is breathing the same air.

Eventually, that air becomes stale air, which can lead to head colds and respiratory issues.

Fortunately, it is possible to improve your Minnesota air quality through your HVAC system.

When considering all of the contaminants that can affect your Minnesota air quality, the ability to clean the air becomes even more important.

Some of those contaminants include:

  • Radon
  • Carbon monoxide
  • Household products
  • Tobacco smoke
  • Mold or mildew
  • Pollen
  • Radon
  • Nitrogen dioxide
  • Lead particles
  • Asbestos in older structures

Improving Indoor Air Quality

If you think the above pollutants look frightening, it’s because they are.

When it comes to your HVAC system, you may be thinking, “but I have a furnace filter on my furnace.”

That’s great if you have a good filter, however, these filters are designed to trap larger particles, such as dust bunnies and hair.

This means that more comprehensive measures need to be taken to improve the quality of indoor air during the winter.


On your own, you can opt for different types of filters, such as electrostatic filters.

These filters require monthly cleaning with pressurized water and can be difficult to clean thoroughly. If not maintained properly, the filters can clog, which can make the blower motor work harder.

Portable Air Cleaner

If you opt for a portable air cleaner, you are only able to clean a specific zone.

These systems also have a tendency to create ozone, and even in small quantities, ozone can hurt lung tissue.

Air Filtration System

The last option is the best option – a professionally installed air filtration system.

At Metro Heating & Cooling, we are able to provide you with whole-home filtration, which means your Minnesota air quality is improved throughout your entire house rather than just a single room or zone.

Today’s air quality systems are very efficient in the removal of particles as small as 5 microns in diameter (a strand of hair is 100 microns).

You can receive great particulate efficiency and even address VOCs and other indoor gasses that may be present in the air.
