Reducing Airborne Allergens in Your Home

The air inside your home can be up to five times more polluted as the air outside. To improve the indoor air quality in your home, consider installing a whole house ventilation system, such as those from Broan, which removes stale indoor air and replaces it with HEPA filtered outside air.

Danny Lipford: Whether you realize it or not, the air inside your home may be as much as five times more polluted than the air outside. Now that complicates issues like asthma and allergies, but it also poses other serious health risks.

To achieve adequate indoor air quality, you need proper ventilation, but this isn’t always a quick fix. You may need more than spot ventilation in the kitchen and bathrooms to control pollutants and allergens.

A balanced ventilation system equalizes indoor air pressure and removes stale air from your home. Now these systems may just introduce fresh air alone, or include Heat Recovery (HRV) or Energy Recovery (ERV) features.

Now, HRVs manage heat loss, so they are ideal for colder climates. As stale, warm air is removed from the house through the HRV, the heat recovery core warms incoming colder, fresh air before it is distributed throughout your home, so there are no unpleasant drafts. The incoming air is filtered so you don’t bring outside pollutants inside.

Broan’s HRVH100SE features HEPA filtration, which captures 99.97% of airborne particles including dust, allergens, and pet dander as small as 0.3 microns. HEPA filtration is very different from electronic air cleaners, because air cleaners typically produce ozone, which itself is classified as a pollutant.

ERVs manage both heat loss and humidity in the air, so they are ideal for warmer, humid climates. Broan’s ERVH100SE not only recovers heat in the cold season, it also recovers the energy trapped in moisture, which greatly improves efficiency. In humid climates, ERVs limit the amount of moisture coming into the home, plus this one also includes HEPA filtration.

Both of these units are also very energy efficient, using 25 percent less power than other ERV and HRV products, saving an estimated $350 a year in energy costs. In order to be sure that these ventilation solutions work efficiently as a system, it’s important to work with building performance professionals who can help put their operation into perspective.
