Coronavirus and Other Contaminants: How To Improve Indoor Air Quality

January 14, 2026
coronavirus: how to keep your air clean

People spend most of their time indoors—about 90%!
But did you know the air inside can be much more polluted than outside? The EPA says indoor air pollution is one of the top environmental dangers in the U.S.

Your home’s HVAC system helps keep you comfortable and also keeps the air inside cleaner and healthier. There are many ways to fight indoor air problems like mold, dust, bad smells, and even germs.

Filtration System

A well-designed and well-maintained HVAC system can help control things like viruses, bacteria, and mold that make people sick.

Air filters are a strong line of defense against tiny particles in the air—some smaller than a grain of dust!
The higher the MERV rating, the better the filter is at catching these particles. But remember: your HVAC system needs to be running for the filters to work.

HEPA filters, often used in hospitals, can trap 99.97% of particles as small as 0.3 microns. That’s super tiny! These filters help improve air quality and may help with health, though they haven’t been tested for the coronavirus.

Air Purifiers

Air purifiers clean the air in your home by pulling in dirty air and sending out clean air. They’re installed inside your ductwork and work whenever the air flows through.

They’re great for:

  • Reducing allergies
  • Removing bad smells
  • Catching mold, pollen, and pet dander

Humidity Levels

Viruses don’t like it when the air isn’t too dry or too wet. The best humidity level is between 40% and 60%.

Big buildings usually have systems to keep humidity in that range, but most homes don’t. That’s why adding a humidifier to your home can help with air quality and your health.

Air Scrubber by Aerus

At LA Construction Heating and Air, we offer the Air Scrubber by Aerus, which uses ActivePure® Technology.

This device connects to your HVAC ductwork and helps clean your home by removing:

  • Pollution
  • Germs
  • Pet dander
  • Odors
  • Dust

It works by sending out negative ions, tiny particles that go out and grab harmful stuff in the air. These ions bring back larger particles like bacteria and allergens that your regular filter may miss.

Inside, the air scrubber has metal tubes and a UV light. As air flows through, the light helps kill germs. It acts like a second layer of defense alongside your regular HVAC filter.

Air scrubbers can even kill some germs and viruses in the air and on surfaces. While it hasn’t been fully tested on coronavirus, it’s been shown to reduce bacteria like MRSA and other triggers of allergies and asthma.

Unlike an air purifier, which cleans the air inside the device, an air scrubber sends out ions that clean surfaces and the air around your home.

At LA Heating & Air we understand, HVAC plays an important role in improving the indoor air quality of your home and business in fighting illnesses and viruses. While the products above are yet to be tested against coronavirus, they have been tested against bacteria, mold, flus and other viruses.
