No. You can purchase diffusers and compatible oils individually. Where a product includes oils, its product page explains the included bottle sizes and quantities.
Where can I see the price and included items?
See the selected product page for current prices, available options and included items. Review your selected items and total in the cart before checkout.
How long do the fragrance oils last?
Oil use varies with the diffuser, intensity and daily schedule. Follow your model instructions and adjust the settings to your space.
Which diffuser is right for my space?
Compare the coverage, placement and controls on each diffuser page. Room models, car diffusers and whole home HVAC systems suit different spaces. Contact us if you need help choosing.
How do I choose compatible oils?
Check your diffuser instructions and the oil product page for compatibility and bottle size. Use oils intended for your model, and do not add water to a waterless cold air diffuser.
Is shipping free?
Free shipping is available on qualifying US orders of $150 or more. See the shipping policy for details.
What is the return policy?
Diffusers include a 30 day satisfaction guarantee. Request approval before sending a return. Return the diffuser in its original packaging as received, with all packaging included and all oil removed. Missing packaging, or damage caused by oil left in the diffuser, voids the refund. Opened fragrance oils cannot be returned, but unopened oils in original packaging are eligible for a return request within 14 days of delivery.
After the first 30 days, manufacturer warranty coverage runs through 1 year from the purchase date. A shipping and processing fee applies. Fees are ECHO $69, Elite Mini Pro $99, HALO Tower $149, INFINITY $149 and Car Pro $49. The ECHO Mini fee is $49. Read all return conditions.
