Healthy Indoor Air Quality in Baltimore & Columbia, MD

Rate Your Indoor Air Quality with Hydro Clean

At Hydro Clean, we use an indoor air quality index that measures the cleanliness of your indoor air. A Green rating of 0 to 50 indicates minimal amount of harmful pollutants. A Yellow rating of 51 to 100 indicates acceptable air quality, with some pollutants present that may affect sensitive individuals.

An Orange rating of 101 to 150 indicates air quality that could make individuals with allergies uncomfortable. A Red rating of 151 to 200, on the other hand, means that most individuals (even those without known allergies) are likely to experience sniffing, coughing, and eye irritation. A Purple rating of 200 to 300 refers to terrible and unhealthy air quality. Exposure to indoor air with a Maroon rating of 300 to 500 may cause serious health problems.
