Filter Monitoring

HVAC systems utilize filters to ensure cooled or heated air is clean before being delivered to the desired space. Over time as filters are used they can become contaminated and increase the pressure losses in the HVAC system. SMI has a family of low pressure sensors designed to detect such pressure build ups and indicate the need to clean or replace a filter.
