The Chloraguard® indoor air purification system removes chloramines and other airborne contaminants commonly found in indoor pool spaces. The unit's filter uses Multi-Mix®, a chemical media, to the contaminants. The system is a gas-phase air purification module option installed at the factory on the return air of new Dry-O-Tron® dehumidifiers. In addition, the purification system can be retrofitted in the field on any existing pool dehumidifier brand, the company says.
