Located in Dachang (大廠), the core area of Beijing-Tianjin-Hebei region, Hebei Guojing Yihe (域見頤和) is an all-ages friendly residential area with elements of ecology, humanism and health.

The property adopts HI-RE (七恒系统) system, which use the principle of radiation in heating and cooling system, prevent direct blowing of cold air, made elderly and kids feel more comfortable.  In addition, after installation of Monitair’s bipolar ionization devices, providing residents with a healthy and comfortable indoor living environment.

Bipolar ionization devices were installed in the fresh air unit HVAC , the devices can release positive and negative ions as well as free radicals to oxdise organic compounds to intermediate byproducts and eventually to terminal products of carbon dioxide and water. Processes involving reactions with air ions include: (i) recombination with other air ions, and (ii) reaction with gaseous molecules. These two processes may be involved in the removal of volatile organic compounds and increase the amounts of ions in indoor to more than 10 times as outdoor, which improve indoor air quality as fresh as in nature.  The property owners said that the air quality (including temperature and humidity) was improved after the installation of bipolar ionizer, so as the smell after renovation was improved.

High ion levels are proven to deactivate viruses, bacteria, and mould.  Monitair bipolar ionization technology has been proven by independent laboratory tests, can effectively remove 99% Influenza H1N1, H5N1, Escherichia Coli and 99.9% Coronavirus. As a result,  provide a better living environment for elderly or patients with allergies and respiratory illnesses.
