Do Scent Fill refills work With Yankee Candle® Makers of Scent Plug® or Bath & Body Works®  WallFlowers®?

No, our refill bottles do not fit the Wallflowers® or Scent Plugs®. We do sell our own Scent Fill® branded oil warmer and are compatible with Air Wick® scented oil warmers.

How long will my Scent Fill® refill last?

This depends on several factors.

1. It depends on your type of plug in warmer / diffuser. Our customers and our testing indicate the Air Wick warmers (With grey fragrance level adjustment for fragrance control on top) enable faster evaporation (more scent throw) and control.

2. Fragrance setting on warmer. The majority of scented oil warmers have an adjustable dial for fragrance intensity that usually works by exposing more wick surface to the heating element, resulting in emitting more fragrance because of faster evaporation.

3. It depends on the type of scented oil refill you purchased. Most natural scents last between 7-30 days. Most of our scents can last approximately 10-45 days when warmer is set to low fragrance control.

4. Ambient conditions such as humidity, air circulation, and temperature contribute to the longevity of refill life. Our testing noted faster evaporation rates in larger rooms.

Why do natural refills not last as long as synthetic refills? 

Synthetic store bought refills contain synthetic fragrances, solvents, and additives that regulate and slow evaporation. All our natural product line does not contain synthetics or solvents. Our products with the 100% Natural icon designate 100% natural content.

Why is my bottle not filled to the top?

Our plug in refill bottles are sold as 20 ML. Our precise liquid filling machines use peristaltic pumps for high accuracy. This is the same pump technology used in dialysis machines. Our filling machine is set slightly above 20 ML or .68 OZ. At 20 ML the bottles are filled to the top of the 2 ML of fragrance oil during storage and transportation and give the appearance of not being full. You pay for 20 ML and you will have at least 20 ML often 21- 22 ML of scented oil. By comparison; Glade brand Plugins contain 19.8 ML, Air Wick refill contain 20 ML and Scent Plug by Yankee Candle contains 18.5 ML of scented oil.

Why was my refill packaged in a plastic bag without a tag?

Your refill was either a brand new item that we don't have a Scent Fill® tag for yet. Or it's a popular item that we ran out of tags for. 

Are your refill bottles glass or plastic?


What should you do with empty bottles and caps?

We encourage customers to add empty glass refills to their own recycle bins for local pick up.  

Are all your plug in refills 100% natural? 

No. We offer 2 "tiers" of refills only one tier is 100% natural. You can filter these categories in the shop menu.

1. Essential Oil Based- Products in this category all contain at least 2 natural essential oils or natural isolates which are naturally distilled fragrance molecules from  essential oils. Natural content typically ranges between 9% and 60% in the essential oil based category. Essential oil based scents are based on combinations of essential oils e.g spearmint eucalyptus, rosemary mint etc this category may contain synthetics.

2. 100% Natural- As the name suggests, this category is all natural. They may contain natural isolates which are natural ingredients distilled from natural material. Carrier oils are also all natural. We call out the all natural with a 100% natural icon in the product image.  

Are your scents organic?

Our scented oil refills are not certified organic. Some of our natural scents include 17 or more ingredients. The aromatic plants we use are a commodity and depending on crop conditions and natural weather events, sources can and do vary.  Certifying each ingredient from every farm or source would be cost prohibitive.

How should I store my plug in refills?

Natural essential oils are products obtained from vegetable, plant, bark, tree and seed raw material. This natural material is more susceptible to potential degradation especially with exposure to UV and fluorescent lights as well as higher temperatures. Different essential oils have a variety of reactions over different periods of time. We recommend storage in a cool dark area away from sunlight, fluorescent lighting and heat.

Can I adjust the amount of fragrance on  Air Wick® oil warmer?

View our blog article on how to adjust Fragrance level on Air Wick scented oil warmers.

Always store Scent Fill refills upright especially after receiving in the mail- When you receive your refills, always store bottles upright. Store upright for at least 10 minutes prior to first use. When the bottle is stored on its side, the scented oil can drain into the cap. This will often happen during shipping. The wick holder is designed with a small pin sized hole to allow fragrance oil accumulated in the cap to drain back into the bottle when stored upright.

If your order has left our facility, we are asking you, the customer, to understand that we are a small business and every time we have to re-ship your order we end up losing money on the sale.

Do you ship to Canada the UK or Australia? Not at this time due to international shipping issues.

Why is it important to have plug in warmer upright? 

Your plug in warmer must be upright or scented oil will drip and leak. The electrical plug on the oil warmer does rotate, so make sure it's plugged in upright as shown below to avoid leaking.

What is the shelf life of my Scent Fill refill?

Your refills are good for a minimum of a year. Scented oil blends containing natural citrus oils such as orange, lemon, and bergamot can begin to lose fragrance intensity after a year. Scented oil blends with vanilla or peppermint natural oils tend to discolor to a brown hue over time. This does not necessarily affect the fragrance intensity or characteristics, but usually only the appearance. You may also notice some accelerated discoloration when plugged into your wall warmer unit due to increased heating temperature. If you are used to using synthetic fragrance plug in refills, you likely have not noticed this discoloration that is a result of natural oil content.

Will you disclose your ingredients?

We will provide a list of ingredients for our 100% natural options. For most 100% Natural products, ingredient list can be found in the Q&A in the  product review section of individual products. We partner with fragrance houses and perfumers/chemist for research and development that consider our scents that are not 100% proprietary. We are prohibited from disclosing all ingredients under a non-discloser agreement for these scents. . Our all natural supplier is over a 110-year-old company who uses NPA (Natural Product Association) for all natural certification. We are paying up to 4-8 times the cost per pound for our fragrance than synthetic store bought type formulations. Our natural formulas may contain natural isolates. Isolates have been “isolated” from their natural sources using the least invasive methods of extraction, usually separated using fractional distillation.  While many isolates have unnatural sounding names, they are distinguished from synthetics because they are odor molecules separated from natural materials. The use of isolates is standard in modern natural perfumery. We can provide allergen statements and natural content certification on request.  

Do natural ingredients have any disadvantages?

Yes. Natural ingredients are not as consistent as synthetic ingredients. Natural ingredients are extracted from plants, trees, bark, fruits, and seeds which are subject to weather and a number of natural conditions. Sources of our ingredients can vary from different regions based on crop conditions. Characteristics of the same natural ingredient can vary from region to region.

Natural ingredients usually have less shelf life than synthetic ingredients.  It's a good idea to keep your natural refills away from sunlight.  Natural ingredients can discolor over time, especially natural vanilla which can appear to brown in appearance.  Keep in mind organic matter is subject to decomposition, so it's best to use your refill within a year.

Why do some refill wicks in my plug in refill turn brown over time?

Our refills use porous PET fiberglass wicks with a density designed to maximize absorption and evaporation without becoming clogged. The natural oils predominantly blends with vanilla and peppermint have material absorbed in and filtered by the wick that leaves color as they pass up through the wick.

Does Scent Fill test products on animals?

No. Scent Fill and its suppliers do not test products on animals. 

Are Scent Fill Products safe for my pet?

Because even some All Natural products are unsafe for our four-legged friends (take chocolate’s toxic effect on dogs, for example), we cannot make a blanket statement about pet safety and Scent Fill plug-ins. Even naturally occurring elements, like peppermint, which is known to keep away spiders and rodents, can be unpleasant for cats. Other naturally occurring elements, like lavender, can be soothing for both cats and dogs One thing is certain, Scent Fill brand plug-in refills do not contain harmful phthalates (they-lets). Please remember all products are not safe for ingestion or topical use.

Can I buy Scent Fill Plug-in Refills in bulk?

The use of scented oil plug in warmers is extended beyond residential air care. The convenience of low maintenance, the long-lasting fragrance is used in numerous commercial applications requiring bulk purchasing. Unlike ionic diffusers which require cleaning and constantly adding essential oils, a plug in refill is placed in a warmer to deliver continuous fragrance for up to 90 days. We often ask our commercial customers about their specific applications and get some interesting answers:

  • Dentist and orthodontist offices use scented oil warmers to help patients relax.
  • Spas use scented oil to create a comfortable ambiance.
  • Veterinary practices use natural lavender refills to calm animals.
  • Casino's have purchase refills to eliminate stale smoke and relax customers. 
  • Hotels have purchased our refills for lobbies and common areas.
  • Offices use peppermint refills to energize staff and ward off airborne illness. 

    In a response to these needs, we have implemented tiered pricing with all of our scented oil refills. With our familiar classic collection, you can get the tiered discount when combining any combination of the 5 products in this collection i.e. you buy 2 each of the 5 varieties of refills and receive the 10+ bulk discount. Bulk Pricing combined with the added time-saving benefit of Free Shipping and fast 2-3 day delivery to your business makes scent fill an obvious choice.

    If your bulk purchase requires quantities above these tiers please contact a team member for assistance. As the manufacturer, we can develop a custom pricing program best for your needs. We can be contacted at  info@scentfill.com or (866) 223-7561
