What Is a Home Air Exchanger?

Definition

• According to the Modern Solutions website, air exchangers allow fresh air to enter a home while pushing out the stale air from inside, according to the Modern Solutions website.

Types

• Alpine Home Air lists two basic types of exchangers, heat-recovery ventilators for cold climates and energy-recovery ventilators for warm climates.

Benefits

• Restoring oxygen levels in a home can make residents feel more alert and energetic, according to Modern Solutions. This process can also help remove moisture to discourage the growth of mold and bacteria.

Shortcomings

• The amount of oxygen an air exchanger introduces into a home may prove negligible in a larger home. Additionally, Modern Solutions warns that the moisture pulled from the air can settle inside the unit, creating its own mold and dust problems when that air is recirculated.

Alternatives

• Since home air exchangers typically cost $1,500 to $3,000, Modern Solutions recommends air purifiers, proper ventilation and high-efficiency furnace filters as more affordable ways to ensure clean air at home.
