❓ Frequently Asked Questions

1. What is a whole-house HVAC air freshener system?

It's a scent delivery system that connects to your HVAC unit to distribute fragrance evenly through your home's air vents. It offers consistent, low-maintenance freshness in every room.

2. How is it different from plug-ins or sprays?

Unlike plug-ins or sprays, whole-house systems scent your entire home at once. They're longer-lasting, more discreet, and don’t require daily reapplication.

3. Are these systems safe for my HVAC equipment?

Yes—when used correctly. Choose systems designed for HVAC use (like scent pads or duct-mounted dispensers) and avoid products that leave residue. Filterbuy only recommends HVAC-safe options.

4. How long do the scents last?

Most scent pads and refills last 30 to 60 days, depending on the system and usage level. Auto-refill options are available to help you stay consistent.

5. Can I use essential oils with my HVAC system?

Yes, if your system is compatible. Some diffusers are designed specifically for HVAC integration and work with natural oils for a clean, toxin-free scenting solution.
