Calculator and comparison tools

Room dimensions and airflow calculations run in your browser. Sharing a calculator setup places the dimensions and settings in its URL, so anyone with that link can see them. Avoid including details you do not wish to share.

Comparison selections may be kept in your browser and included in a shareable URL. These tools do not require an account.

Analytics and hosting

When analytics is configured, this site uses Google Analytics to understand page visits and shopping-link clicks. Shopping-link events may include the product identifier, link placement and page path. Google Analytics may use cookies or similar technologies. Your browser controls can restrict cookies and tracking.

The hosting provider may process technical request information such as IP addresses and browser details to deliver and protect the site. Calculator results are not submitted to a site database.
