Explore the advantages and characteristics of the double inlet fans and the EC Backward Centrifugal fans in the field of fresh air purification, to reveal the secrets of efficient purification and create a fresh and comfortable indoor environment.
Air cleaners and HVAC filters are designed to filter pollutants or contaminants out of the air that passes thru them.
Air cleaning and filtration can help reduce airborne contaminants, including particles containing viruses. Portable air cleaners (also known as air purifiers) may be particularly helpful when additional ventilation with outdoor air is not possible without compromising indoor comfort (temperature or humidity), or when outdoor air pollution is high.

The HVAC systems of large buildings typically filter air before it is distributed throughout a building, so consider upgrading HVAC filters as appropriate for your specific building and HVAC system (consult an HVAC professional). The variety and complexity of HVAC systems in large buildings requires professional interpretation of technical guidelines.
