Breathing Easier This RSV Season: How Your Home’s Air Can Support the People You Love

Your home is not neutral. Your home is shaping how you feel, every hour of every day, whether you notice it or not.

It’s also where your body recovers. After a day of traffic air, crowded rooms and the colds and viruses that go around every fall, home is where you’re meant to rest and rebuild. In Beyond Comfort (p. 87), our co-owner Carla recalls a client who put it this way: “By the time I get home, I just want my exhausted body to stop defending itself from everything it’s been fighting all day.”

That matters most this fall RSV season, when families with new babies and aging parents spend more time indoors. We’re a home comfort company, not a medical clinic. So we’ll stick to what public health agencies actually say, and to the parts where your home’s air has a role.

What RSV is, and who it affects most

The Public Health Agency of Canada describes respiratory syncytial virus (RSV) as a common respiratory virus that follows a yearly seasonal pattern. By age 2, most children have had an RSV infection. For most people it causes a mild, cold-like illness that clears up in 1 to 2 weeks. But it can also lead to bronchiolitis, pneumonia and hospitalization. [1]

Some people are at higher risk of severe illness, including premature infants, babies under 6 months, older adults, and adults with conditions such as asthma, diabetes, heart disease or COPD. [2] Here in Alberta, Alberta Health Services notes that RSV activity typically rises in the fall and winter, though timing changes from season to season. [3]

Start with the proven protections

Before we get to air, here’s the part that matters most. Public health guidance puts vaccination and personal measures first. Canada recognizes two options that help protect infants from RSV disease: vaccinating during pregnancy, or giving the baby a monoclonal antibody after birth. Vaccines are also available for higher-risk adults. [2] The Government of Alberta says it will offer Beyfortus® (nirsevimab) free-of-charge to babies born in the hospital during RSV season (November through April). [3][4] Alberta also offers a publicly funded RSV vaccine to eligible adults, including adults 70 years and older living in the community. [4]

Ask your health care provider what’s right for your family. Staying home when you’re sick, washing your hands, and covering coughs all help too. [2][5]

Your home’s air supports these steps. It doesn’t replace them.

1. Ventilation: let your home breathe

The Public Health Agency of Canada explains that good ventilation swaps indoor air for outdoor air, which “helps reduce the buildup of infectious respiratory particles in indoor air.” [5] Calgary winters make opening windows tough, which is where mechanical ventilation comes in.

A heat recovery ventilator (HRV) brings in fresh outdoor air and exhausts stale indoor air, while keeping most of the heat inside. Canada’s home ventilation guidance (written during COVID-19) advises making sure HRVs and ERVs are properly installed, maintained and running continuously except during servicing. [6] Kitchen and bathroom fans that vent outside help too. [5]

2. Humidity: aim for 30–50%

Health Canada recommends keeping indoor relative humidity between 30% and 50%. [7] Federal ventilation guidance notes that very low humidity can shrink airborne droplets so smaller particles stay suspended longer, and that too much humidity causes condensation, mould and dust mites. [6]

Calgary’s dry winter air can push homes below that range. A properly sized humidifier, managed so your windows don’t drip, helps you stay in it.

In the symptom table in Beyond Comfort, we pair one common frustration with a solution: dry air worsening colds or flu → steam humidity → faster recovery, fewer symptoms. That row describes what we commonly observe in homes, not a medical promise. Humidity doesn’t prevent or cure RSV, colds or flu. What public health guidance does give us is the target: keep indoor humidity in Health Canada’s 30–50% range. [7][8]

3. Filtration: the right filter, not just the biggest one

Federal guidance says to use the highest-efficiency filter your forced-air system can handle without restricting airflow. A higher MERV rating can capture more small particles. But a filter your system can’t handle can reduce airflow, cause mechanical damage or let air go around the filter. Your furnace only filters air while its fan is running. [6]

Health Canada adds that filtering the air works best alongside good ventilation and reducing pollution at the source, not as a fix on its own. [7]

Bedroom air for kids and seniors

Night is when the body does most of its recovering, and little ones and older parents spend many hours in a bedroom, often with the door closed. Two things tend to build up quietly overnight: dry air, especially in a Calgary winter, and stale air in a closed room. Some simple checks:

• Fresh air. Health Canada suggests leaving interior doors open, keeping heating vents clear of furniture, and keeping beds away from outside walls so air and heat can move. [7]
• Steady humidity. Aim for the same 30–50% range in the bedroom, not just the hallway where the thermostat sits. [7]
• Clean air. Public health guidance recognizes a properly sized portable HEPA air purifier as one way to filter particles in a room. [5]
• Safety. Health Canada advises a working carbon monoxide alarm beside each sleeping area. [7]

No single product prevents illness. But a bedroom that’s working with you gives your body one less thing to defend against while it rests.
