Do I need to be concerned about airflow?Updated a month ago

It's a great thought! But not with our filters :)

All Windmill Filters have been tested and approved for residential use. The trick though is to make sure you replace your filter on time. A clogged air filter (i.e. one that is not replaced on time) can severely limit airflow, increase energy costs, and potentially cause damage to your system. If you ever feel like you forget to replace your filters, or need help knowing when it's best to do so, that's what we're here for! Our free text reminders will ensure that you replace your filters on time, every time (without you ever having to think about it).
