uHoo is an air sensor and not an air filter. It provides you with the data you need to make specific changes in your habits that contribute to unhealthy air. For instance, when buying a new cleaning product or a new furniture, you’ll be able to know if it contributes to indoor air pollution in your home or office. uHoo does this by alerting you when the air quality reaches unhealthy levels. It also automatically provides recommendations of what you can do in that moment to get better air quality. Having an air filter / purfiier is great, but you won’t actually know whether it is effective or not unless you have a way to measure it. Having uHoo allows you to understand the air you breathe and help you identify the factors that contribute to unhealthy air, leading to a more long-term and effective solution.
