Installed in the loft, LV-EVL-H draws, filters and lightly warms incoming air before feeding it through a central ceiling diffuser. This continuous, tempered airflow dilutes humidity and pollutants, pushing stale, moist air out through natural leakage paths for a drier, healthier living environment. Built by EnviroVent, the LoftVent platform uses high-efficiency motor technology for low running costs, with easy-access, long-life filters for simple maintenance. The H model’s integral heater adds comfort in colder months, while smart control elevates from background trickle to boost during humidity peaks after bathing or cooking.

First4Ventilation says:

"The Envirovent units are a real work-horse in PIV terms getting the job of extensive movement of air throughout the property done with the minimum of fuss. A solid performer from Envirovent. This one gently warms the filtered air being pushed through the property."
