Fresh-air questions, answered

What's an ERV?

An ERV — energy recovery ventilator — is a quiet machine that continuously pushes stale indoor air out and pulls fresh, filtered outdoor air in. As the two streams pass, it recovers heat and humidity, so you get all-day fresh air without throwing away the energy you paid for.

ERV vs HRV — which do I need?

An HRV transfers heat only. An ERV transfers heat and moisture, so your home stays balanced instead of bone-dry in winter or muggy in summer. For most modern homes and mixed climates, an ERV is the better all-around choice — every UpgradeAirKit is built around the LifeBreath MAX XTR ERV. Read the full ERV vs HRV comparison.

Why LifeBreath?

We take that proven ERV and build a complete kit around it: distribution, controls, filters, and real tech support. Shop LifeBreath ERV kits.
