Specialists in custom air filters

When it comes to indoor air quality improvement, no two indoor spaces are the same. Depending on the unique requirements of your building, custom size air filters could be the solution you need.

Unlike standard sizes such as 24x24x2, 20x25x2 and 20x20x2 which are designed to fit common configurations, many systems require customized dimensions. In many cases, this will be because your HVAC system is designed for a particular application. In other cases, standard filters may simply not provide the precise fit you need, leading to gaps that can compromise air quality and HVAC efficiency.
