What is a candle diffuser and what’s it for?

For those who burn scented candles, it takes a long time to fill the room with the candle fragrance.
VelaRosa is a candle fragrance diffuser that quickly fills any room with your candle fragrance using a fan.  Sensory booth testing from a major direct selling company shows that this product can fill the room with fragrance in 10 minutes.  We tested this ourselves in two similar-size bedrooms (10 ft x 11 ft x 8.75 ft high).  Note that rooms much larger than this require more time for fragrance diffusion.
When the time expires, the fan stops, and extinguishes the candle flame.
The main intent of this product is to improve hot fragrance throw, as well as to improve candle safety.

How long does shipping take?

First it's important to know that order processing time is separate from delivery time. Processing time includes picking and packing products and transferring to shipping carriers. Delivery time is the time it takes carriers (e.g., UPS) to ship the package to the customer’s location. The estimated delivery dates shown on the checkout page do not include processing time.

This is an example of delivery times once you get to the shipping page at checkout.

Delivery time

All orders are processed within 1 to 2 business days (excluding weekends and holidays) after receiving your order confirmation email. You will receive another notification when your order has shipped. During periods of high volume, processing time may increase.

Can you use a bigger candle?  Is it only for tea lights?

For now, only tea lights. It's possible that you could use a small votive (2" diameter) in a glass but we're still testing if this impacts the fragrance throw. I’m using Yankee Candle Lavender Vanilla tea lights and they smell great. One of the tests we want to run is to compare the strength of a three-wick jar candle, to a single tea light with the diffuser.

How does it work?

Naturally, if you place a glass dome over a candle it will go out in a few seconds. However, if you place a fan under the candle and blow fresh air into the dome, it keeps the candle lit.
This diffuser has a battery-powered fan inside the base that provides a constant flow of fresh air to the candle flame.  The exhaust air picks up the candle’s fragrance and disperses it out into the room.  A protective outer cover prevents you from touching the hot inner glass dome.  The fan is on a timer and when the fan stops, the flame goes out.

Most tea light candles come in a plastic container, can I use them in the diffuser?

Yes, you may place the tea light and its plastic container inside the glass tea light holder. However, we prefer to burn the candle directly in the glass container. To easily remove the candle from its plastic container, place the tea light in the freezer for an hour or more, and then pull the candle from the container. 

How long do the batteries last?

We ran the diffuser for 2 hours per day on a full charge and it ran for over 30 days.

How does the glass not get covered in soot?

No.  Two reasons why there's no soot...
1. The glass dome is high enough that the flame doesn't contact the dome.
2. The fan is circulating enough air that there's no time for the soot to build up on the top of the dome. If we were to slow the fan down just enough to sustain the flame, you would begin to see some soot on the top of the dome. 

However, if the wick is not trimmed, it's possible that the fan will not be able to exhaust the soot fast enough and soot will form at the top of the dome.  The dome will then need to be cleaned.

How long does the candle burn for?

The switch on the side sets the amount of time (1/2 hr, 1 hr, or 2 hrs) and when the dome is twisted, the fan turns on.  After the timer expires, the fan stops and the candle extinguishes.

Does the candle burn out faster with a candle diffuser?

Actually, it's the opposite. Because the fan regulates the flow of air, the wax burn rate is regulated. The flame height is also limited by the wax pool. When you place the tea light in the bell jar, the heat melts all the wax after 25-35 minutes. This causes the wax to rise slightly, limiting the flame height for about the first 2 hours. As the wax level decreases, the flame gets larger, which increases how fast the wax is used up.

In a timed test, using the same tea light candles, the candle in the VelaRosa® diffuser burned for 1 hour 4 minutes longer than the stand-alone candle. NOTE, the diffuser's safety cover was removed for visibility of this test and NOT normal use. With the actual product, the diffuser's protective cover is permanently attached to the glass dome. See burn test video.
