# Homedics SereneScent Vanilla Cedarwood Diffuser Oil, 120 ml Diffuser: Homedics SereneScent Vanilla Cedarwood is a 120 ml fragrance oil refill formulated for waterless diffusion. Its described notes move from coconut water to vanilla, cinnamon and clove, then cedarwood and guaiacwood. The listing gives two different usage estimates, so treat the advertised duration as dependent on operating schedule and intensity. - [Original product page](https://best-deals.pro/product/homedics-serenescent-vanilla-cedarwood-diffuser-oil-120ml) - [View offer](https://best-deals.pro/visit/homedics-serenescent-vanilla-cedarwood-diffuser-oil-120ml) - Market: US - Language: en-US - Currency: USD - Brand: Homedics - Model: ARMH-EO120VCD - Category: Grocery & Household > Household Cleaning - Price: 39.99 USD - Previous price: 59.99 USD - Discount: 33% - Price checked: 2026-11-14T06:34:12.232Z - Rating: 4.4 / 5 - Reviews: 145 Prices and deal status are the latest recorded data, not a guarantee of availability.

The listing also says oils can be used in traditional ultrasonic diffusers by adding drops to water, although the refill is primarily formulated for waterless diffusion. Check the full ingredient information if you have sensitivities. Keep out of reach of children, avoid topical use and contact with eyes or mucous membranes, and note the stated possible skin irritation. Consult a healthcare practitioner if pregnant, lactating or managing a medical condition. ## A good fit for - Owners of compatible Homedics SereneScent waterless diffusers looking for a warm vanilla and wood fragrance. - Buyers who prefer a larger oil refill and are comfortable with duration varying by intensity and daily operating time. ## Less suited to - Anyone who needs a complete diffuser rather than a refill. - People who need a verified use duration or confirmed compatibility with a particular non-Homedics diffuser. ## Customer feedback Customer feedback highlights the scent and perceived quality positively. That may matter most to buyers choosing a fragrance profile, but it does not establish that the scent will suit everyone. The overall rating distribution is mostly five-star with some lower ratings, and does not explain individual experiences or resolve the listing's conflicting duration estimates. - Positive themes: Customers mention the scent positively. - Positive themes: Customers describe the oil's quality positively. ## Frequently asked questions ### Does this include a diffuser?
