The Dylos DC1100 air quality monitor continuously checks home or office particulate levels. It is a laser particle counter that counts and sizes individual airborne particles. The monitor sizes small (fine dust, bacteria, mold, etc.) and large (coarse dust, pollen, dust mite debris, etc.) particles. It stores 30 days of air quality historical data for analysis. In order to evaluate how well the equipment cleans the air, the device can be used to measure and monitor allergy and asthma airborne particles before and after installation of IAQ equipment, says the manufacturer.
