LG ventilation solution ERV is an efficient solution for fresh indoor air. A variety of energy-saving technologies and air purifying filters allow you to breathe healthier air.

Natural ventilation can waste energy, but LG ERV provides fresh air from outdoors and reduces polluted indoor air. The ERV saves energy with its heat exchanger, which loses virtually no heating or cooling energy.

ERV works in conjunction with an indoor unit to save energy by operating more efficiently than a ventilation system alone.

ERV offers many energy-saving technologies. The heat exchanger saves up to 24% more energy than natural ventilation, and works with other features to provide total energy savings of up to 40%.
LG ERV senses the outdoor temperature and adjusts operation according to the weather conditions, saving 6.1% more energy annually.
LG ERV exhausts indoor heat and supplies cool outdoor air indoors on summer nights to save 5% more energy annually.

LG ERV reduces energy loss by 4.6% annually with automatic fan speed control that adapts to CO2 levels.
LG ERV saves reduces heating and cooling energy loss by 0.9% annually by delaying ERV operation so that the air conditioner and ERV operate simultaneously only when necessary.
*’Suspended Operation’ function on remote control.
*Based on an LGE internal simulation of an LG air conditioner and LG ERV operating together, the heat exchanger saves up to 24% more energy than natural ventilation and works with other LG ERV features to provide total energy savings of up to 40%. Results may vary depending on the environment. Simulation Conditions: Based on ERV (1,000CMH) + Multi V 5 (12hp) / 455m2 office space, Cooling 26℃ / heating 21℃, e Quest 3.65 / Daily operation in winter conditions.
A CO2 sensor monitors CO2 levels in the room. The CO2 level is continuously displayed on the screen of the wired remote control, and an alarm indicator appears when levels exceed 900 ppm. The ERV uses this information to automatically control fan speeds.

By installing a basic filter on the front of the total heat exchanger and an ISO grade filter behind the total heat exchanger, inflow of fine dust and pollutants from outdoors is reduced.
*ISO rate air filter is optional.

*ISO rate air filter is optional. ISO rating according to ISO 16890:2016.
*The air filter (Model number : AHFT035H0) performance was tested by an ISO 16890-1:2016 Air Filter Test by using DEHS and KCl aerosol with the condition of air flow rate of 0.278 m³/s, air temperature of 23-24 °C and relative humidity of 44-49%. The result was an ISO rating of ePM1 75%. Results may vary depending on the environment.
LG ERV DX has humidification and dehumidification functions, making it a good match for spaces where you need both temperature and humidity control. Humidity can also be monitored through the wired remote control.

If dust clogs the filter, an alarm that informs you that the filter is contaminated appears on the remote control screen. You can then replace the filter based on actual contamination levels.
