$199 with your first scent refill, or $299 with your first scent refill included, no subscription.
Setup takes under 30 minutes. Standalone units plug into any outlet. HVAC connected units mount near your existing air handler with no ductwork changes required.
Set it anywhere. Plug it in, add your scent refill, and it fills the room. No installation, no tools, no waiting. Works on a shelf, a console table, a bedroom dresser, anywhere you want fragrance.
Skip the single room. This same unit connects directly into your home's existing HVAC system, so your scent travels through the ductwork and fills every room your air already reaches. One device, whole home coverage.
Works with standard central HVAC systems. Not compatible with mini-split systems. If your HVAC unit is hard to reach, a longer connector tube (up to 15 feet) is available. Contact us for details.
What is an HVAC diffuser, and why does it matter?
Most home fragrance (candles, reed diffusers, plug-ins) only scents the room it sits in. An HVAC diffuser works differently. It taps into the same ductwork that already heats and cools your home, so every time your system runs, it carries fragrance through every vent, into every room, at the same time.
That means no more buying five plug-ins for five rooms, no more a hallway that smells like nothing while the living room smells like everything. One diffuser, one scent, your whole house.
Installation is simple: connect it near your air handler, the same place your HVAC system already lives, and it's done. No rewiring, no ductwork modification, nothing structural, just a few minutes and you’re set.
Aeren Air Collective is not an HVAC company and does not provide HVAC advice. The connector only goes into the ductwork itself, never into the furnace, AC coils, or any other HVAC equipment. If you're unsure where your ductwork begins or aren't comfortable installing it yourself, contact a licensed local HVAC technician, who can typically do it in a few minutes.
