Vents TwinFresh Comfo RA1-50-2
#1 in Single roomFull review
A low cost, very quiet way to bring fresh air into one bedroom or office without ducts. Buy two for a larger room, since one unit moves little air in recovery mode.

A wall mounted ERV and air purifier in one for a single large room or small apartment. Buyers who want maximum fresh air per dollar will do better with a ducted unit.
