- Fits both the A/C Scenting System Regular and Pro

- 17.1 oz lasts 30 to 45 days depending on your settings
- Everspray™  propellant: nonflammable, zero ozone impact
- Trial size (5.7 oz) available to test a fragrance before committing to a full can
- Subscribe and save 20%, with free shipping on every subscription order

Fits both the A/C Scenting System Regular and the A/C Scenting System Pro. Both
take the same refill, so you never have to remember which model you own.

It is not for any of our other products. The ScentFlow Mini and Aroma Diffuser
1000 take the Oil Diffuser Refill; the Aromatherapy Stone Diffuser takes Water
Diffuser Drops. And it is not a room spray: the formula is built to be carried
by airflow, so sprayed by hand it falls and makes floors slippery.

1. Lift the dispenser trigger fully before attaching the can.
2. Screw the refill into the dispenser.
3. Place the unit upright in front of your A/C intake filter.
4. Set your intensity and frequency as usual.

Always use upright. Never spray it as a room aerosol.
  • One A/C Scent Refill, 17.1 oz, in the fragrance you choose
  • Roughly 2,400 sprays
  • 30 to 45 days of fragrance, depending on intensity and interval
  • Covers up to 3,000 sq ft

Frequently Asked Questions

 The A/C Scenting System Regular and Pro. Both use the same refill.

The 17.1 oz runs 30 to 45 days depending on your spray interval. The 5.7 oz trial size runs up to 10 days.

The 17.1 oz for your regular fragrance. The 5.7 oz trial when you want to test something new before committing a full can to it.

About 2,400 in the 17.1 oz.

 Yes. Swap the can and the new fragrance starts on the next spray. Nothing to clean.

20% per delivery, plus free shipping on every subscription order. Change the frequency, skip, or cancel anytime.

Most people set six weeks, which tracks the 30 to 45 day range with a little margin. Adjust it once you know your own interval.

No. The formula is built to be carried by airflow rather than to hang in the air. Sprayed directly it falls, makes surfaces slippery, and can stain fabric. Our Room Spray is the product for that. Does the trial size cover less space? No. It scents the same 3,000 sq ft with the same perfume at the same strength. The only difference is how long it lasts: around ten days instead of thirty to forty-five.

Around ten days at a typical setting. Run it at a shorter spray interval and it goes faster; a longer interval stretches it out. Same variables that govern the full-size can, on a third of the volume.

    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!
