FAQ
Indoor air quality FAQ
What's the simplest way to improve indoor air?
Start with the basics: a good filter that's changed on schedule, and a clean, well-maintained HVAC system. From there, purifiers or humidity control can help with specific concerns.
Will a better filter restrict airflow?
Some high-efficiency filters can restrict airflow if the system isn't set up for them. We'll recommend a filter or filter cabinet that works with your equipment.
Do air purifiers work with my existing system?
Many whole-home options are installed in or alongside your existing ductwork and air handler or furnace.
