AHAM Standards

Setting the Standard

Have you ever wondered how specs for maximum water removal are measured? For years, the restoration industry has used this phrase to define maximum performance � the best-case scenario under optimal conditions. In reality, you face different environmental conditions on each job, in a wide range of climates and weather situations. How can a spec be relevant to your work if you don’t know the specific conditions under which it was measured?

Dri-Eaz specifies the air temperature and humidity in which we tested each dehumidifier to yield the results. Water removal performance can vary greatly depending on room conditions. Performance at AHAM conditions - 80 Fº/ 60% Relative Humidity (RH) - is so useful because it’s a benchmark. The parameters of the test are clear, and it gives you a baseline for comparing performance. Dri-Eaz publishes maximum water removal at 90 Fº and 90% RH. Although rarely encountered on the everyday job, this represents the highest set of conditions attainable by most environmental chambers. It’s imperative that our test results be both useful and repeatable.

When comparing dehumidifier specs and selecting the unit that’s right for you, it’s important to evaluate performance based on a range of conditions. When you don’t know the precise room conditions for a test, the results are useless.
