Where can I place my reed diffuser for best effect?

The best place is where there'll be a lot of movement between two rooms, such as in a hallway or on the inside close to a door opening if you have a wall unit or shelves.

Somewhere where you will be walking past regularly, to notice the fragrance.

Note not to place the reed diffuser in direct sunlight, because that will cause the diffuser oil to evaporate more quickly.

Does this diffuser release any potentially harmful fragrance or toxins?

No. All our reed diffusers use a vegetable Glycerin derived base oil and essential oils only, there are no industrial fragrance to cause irritation or allergies.

All our home fragrance is entirely natural based ingredients and free from solvent and Petroleum derivatives.
