How do I use AC on, window shut in a diffuser?

Add Tea Tree 3 · Thyme 2 · Peppermint 2 drops to 200–300 ml of water. In a room under 15 m², use 1–2 drops less; in a room over 25 m², add 1 more drop of the main oil.

What can I use instead of tea tree?

Swap tea tree for rosemary or eucalyptus — same herbal family. The blend will shift a little: rosemary is cool, green, herbal and invigorating.

When is the best time to use AC on, window shut?

Use it in closed rooms, on humid days, in monsoon season or after long hours of air conditioning — diffuse in short 20–30 minute runs.

AC on, window shut · Tea Tree, Thyme, Peppermint blend

With the AC running from morning to night, the air turns dry and stale. Tea tree leads, sharp and green, thyme adds a warm, spicy herbal note, and peppermint keeps everything alert. Great for a closed-up office or a bedroom in an apartment building. Run the diffuser for 20 minutes at a time, a few hours apart; for a softer version, use 1 drop less thyme.

How it unfolds

On opening. Tea tree (green, medicinal and clean); peppermint (cool, sharp and clean) rise first, clearest in the first 10–15 minutes.

As it settles. Thyme (warm, dry and herbal with a touch of spice) forms the body of the scent and stays longest in the room.

What remains. With no woody or resin base note, this blend fades fairly quickly — switch it on again after 1–2 hours to keep the room scented.

Safety

Skin irritant

Thyme can irritate skin — dilute well and patch-test on a small area first.

Do not use for children under 6, during pregnancy, or if you have a health condition without asking a professional first. Never ingest essential oils; keep them out of reach of children and pets.
