Frequently Asked Questions

What is cold air diffusion?

Cold air diffusion is the latest technology in the scenting industry. It works by using high amounts of cold filtered air combined with air pressure to diffuse oils into a dry mist of nano particles. This cold air diffusion technology is used in all Aroma360 diffusing systems and ensures consistent and subtle scenting without any highs or lows.

What is the difference between a cold air diffuser and other diffusers?

Most other diffusers work by heating the essential oils and sometimes involve adding water to assist in the evaporation process. Essential oils are very delicate and volatile. When heated, their therapeutic benefits are destroyed. Furthermore, scents that are diffused through methods that involve heat do not disperse well in large areas nor does their scent last long as the molecules fall as they come in contact with the cool air.

Is there a risk my AC unit will be damaged?

The cold air diffusion process turns the aroma oils into a dry mist and therefore does not leave any oil residue in duct work, on furniture, artwork or on equipment. Furthermore, when being installed in the HVAC system, the point of entry is always after the air handler.

Do your systems only work with central A/C?

We have two types of products.
1) The portable line can work in any environment and do not require central A/C. These are the suggested option for areas that have wall AC, split units or heat radiators.
2) HVAC units do require a central A/C system to operate.

Can I lay my unit on an angle or horizontal?

No. When the oil canister is inside the unit, they must always be in their upright position to prevent oil from damaging the inner mechanics of the unit.

Do the HVAC system only work with cold air?

No. Aroma360 can also be used with the fan or heat settings in the central air conditioning system. Warm air will give you a slightly stronger fragrance.

For the HVAC units, do I need to have my AC running at all times?

In order for the system to work the fan must be on. During cool weather turn the fan of your central air conditioner to the ON position (as opposed to AUTO) to ensure the fragrance continues to circulate throughout your home.

What kind of service/maintenance is required?

There is no service or maintenance needed for the HVAC units. Only requirement is to change the fragrance canister once empty.

What is the charge for Aroma360 to come and change the oils?

Oil service can be arranged. Cost will depend on location and number of units to be changed.

How long will the oils last?

When used at the recommended settings of 8 hours/day the bottles last approximately 1 month. The exact length of time will depend on the chosen on/off times.

Are the oils safe with my furniture, equipment, art and pets?

Yes. Since our units use cold air diffusion technology, there is no residue and is therefore safe to use around furniture, equipment, art and pets.

What about sensitivities to fragrances?

Aroma360’s oils are IFRA compliant meaning they are of the highest standards in the industry. Our oils are made from the finest plant derived essences and pure essential oils and have anti-bacterial, anti-viral and anti-fungal properties. Our oils are safe to use around people, pets or plants and are free of carcinogens.

These oils smell so great; can I use them on my skin?

Since our oils contain pure essential oils and plant essences, do not apply these oils topically as they are in pure, undiluted form. If you get oil on your hands, wash the area with soap and water.

I spilled oil, how do I clean it?

If oil is spilled thoroughly clean the area (including the unit) with rubbing alcohol. Please remember that these are undiluted essential oils and should therefore be treated with care.

Where are your oils from?

All oils are manufactured in the USA.

How do I order my oils?

Oils can be ordered online at, by emailing or from your sales representative.

What is an Essential Oil?

Essential oils take the best parts of natural elements for use. Like the plants they come from, Aroma360’s essential oil based fragrances provide health benefits with their natural antibacterial properties, maintained through cold-air diffusion technology.

What is an Aroma Oil?

Aroma oils are a blend therapeutic-grade essential oils and perfume-quality fragrance oils. They are designed to maintain all the therapeutic benefits of essential oils and provide maximum versatility and control of the scenting environment. All aroma oils are hypoallergenic, IFRA compliant and meet the highest safety standards in the industry.
