Ductless design eliminates dusty ducts, complex wiring, balancing, and professional installation. This also means no additional interior work to hide ducting or the need for a separate installation room. No extra work, space, or antifreeze needed. Regular ERVs typically require ductwork (prone to dust buildup), complicated wiring, and post-installation balancing. Professional installation is usually necessary, often along with extra interior work to hide ducting. Antifreeze core protection is a common requirement.

Review: Works As good as we had hoped - works great. ensures a constant cycle of stale air out fresh air in. Review: Not worth it - Build quality is fine. The instructions are really bad. The actual mechanism to connect the core is dumb it’s very hard to make it in line. The worst part is the price it’s outrageous. You can get a full ERV system for this price.
