Everyday scent, in everyday spaces.
Everything you need to know!

Engineered to perform, designed to last

Place the dispenser in front of your central A/C intake filter. Each ultrafine burst is carried through your vents, scenting every room evenly. Your A/C does the work.

No installation, no wiring, no tools. Set it in front of your A/C filter, load the refill, and you're done in minutes. Step-by-step videos included.

It works with any central air conditioning system, in both cool and heat modes, year-round. It's not designed for wall units or split systems; for those, our diffusers use the same perfumes.

One system scents up to 3,000 sq ft evenly from a single A/C unit. Larger home or multiple A/C units? Use one system per unit for full coverage.

Both scent your whole home with the same refills. Regular is set-and-forget: adjust intensity and frequency with the remote. Pro adds full scheduling: days, start and end times, and spray intervals down to the minute.

Each 17.1 oz refill holds about 2,400 sprays. Depending on your settings, that's one to three months of fragrance. Most clients settle around one spray every 20 minutes.

Yes. Adjust intensity and spray frequency anytime: longer intervals for a subtle presence, shorter for a stronger one. You'll find your perfect setting within a few days.

Yes. Our fragrances are cosmetic grade, vegan, cruelty free, formaldehyde free, and VOC free, with a nonflammable propellant. Safety Data Sheets available on request.

The fan needs to be running to carry the fragrance. In cool weather, set your fan to ON instead of AUTO and enjoy it year-round.

You're covered by our 30-day money-back guarantee. And our Miami-based team answers the phone if you need a hand with anything.

    Amazing scents

    I have been using various scents from Doctor Aromas for over a year. Love the way my house smells! My favorite is Blanc but I switch it up during the holidays and go for a more fir scented fragrance. Amazing scents!
