About the Diffuser

How does the diffuser work?

Our diffuser design relies on our iconic hourglass shape, innovative wood core, and the natural mechanisms of gravity, saturation, and evaporation. As the fragrance oil drips top to bottom, it saturates the wooden core, which has been designed for the oil to flow at the perfect intervals so that it evaporates off throughout the day, filling your space with subtle aroma.

Is the diffuser easy to put together and pack up?

Yes and yes, we promise. There are instructions included in the box, and you can view a quick tutorial here. If you’d like to pack it up and use it later, we recommend keeping the full packaging including the end caps to the glass containers especially.

How often should I turn over my Hyascent?

It depends how much fragrance you want! For rooms 200 square feet or smaller, once a day is great. As calming and mesmerizing as the oil in the hourglass is to watch, we don’t recommend turning more than twice a day. When you first get your Hyascent, the wood core will be ready for you to prime it. After you assemble the diffuser, turn it as many times as possible in the first 24-48 hours. This will prime and saturate the wood core with our luxury fragrance oil, making it ready to scent your space.

How long does it last?

The diffuser is everlasting and refillable with the same scent. If you turn your Hyascent once or twice a day, the scent should last around eight to twelve months.

How does a Hyascent hourglass diffuser compare to a reed diffuser?

The design of the Hyascent diffuser lasts 3 to 4 times longer than a typical reed diffuser. Furthermore, the fragrance oil is contained in the patented, iconic hourglass vessel while a reed diffuser is traditionally an easy-to-spill open glass.

Do you sell refills?

Yes! You can order yours here.

What size are Hyascent diffusers?

Our diffusers are 6" tall by 4 1/2" in diameter. Each product package is 14”long x 3 1/2”high x 5 3/8" wide and weighs 3.1 lbs

About the Scents

How do I choose a scent?

We worked with some of the best perfumers in the world to create a sophisticated, layered line of scents. Each fragrance embodies a personality, which you'll see in the product description along with descriptive notes. Take our quiz to find your perfect scent or let our founder pick your scent!

Will the scent fill my home?

Hyascent is designed to bring a subtle fragrance into specific areas or rooms of your home. We’re going more for a delicate whiff here and there. Keep turning it over once or twice a day, and the scent will slowly become more noticeable, more often.

Can I try a sample?

We don't currently have fragrance samples because it's difficult to capture the Hyascent experience in a smaller format. You can visit a Hyascent stockist to see (and smell) our diffusers in person. We recommend calling ahead of time to ask which scents are in stock and available to test as our award-winning hourglass diffusers are so in demand.

What kind of oil is in the diffuser?

Our signature fragrances are custom formulated in one of the finest parfumeries in France. The oil inside of our diffusers is similar to what you'd find in a bottle of your favorite designer perfume.

Is the oil natural?

Unfortunately, there is no all-natural way to create a stable scent; the molecules you find in raw materials are very fleeting and must be bonded to achieve a lasting effect. However, our formulation underwent more than three years of research and development in order to meet the highest California health and safety standards. We wouldn't sell it to you if we didn't feel comfortable having it in our own homes!

Caring for my diffuser

How do I care for my Hyascent?

We recommend flipping the diffuser a maximum of two times a day and not interchanging fragrances.

Can I get a different Hyascent fragrance as a refill?

Hyascent’s ingenuity is that the wood is continually primed with the accompanying scent. The flip side (pun intended) is that we don’t recommend switching scents on the same diffuser. You’ll end up with a mish-mash of multiple fragrances.

Can I use another oil with the diffuser?

Hyascent’s fragrances are specially formulated to have a consistent level of drip, saturation and viscosity with our handmade diffuser. We don’t recommend using other oils, because they may cause leaks and degrade the wood.

Are there any precautions I need to take with my Hyascent?

We recommend pairing your diffuser with our matching coaster, it's the perfect home for your companion to complete the luxury aesthetic. Made of the same premium wood of your diffuser, it has the exact grooves to firmly hold it in place. If our coaster had a dating profile, it would read "Smooth, Protective, Supportive - The Perfect Companion."

You should follow some of the usual safety measures you would take with any liquid containing chemicals not intended for drinking. Hyascent could cause an allergic reaction and may be harmful or fatal if swallowed, so keep it out of reach of children and pets. Avoid contact with eyes, skin and hair. Avoid contact with furniture, fabrics and finished surfaces, as liquid may seep out and spillage may cause permanent staining and/or damage to furniture or other household items.

Is your fragrance made from essential oils?

No, our scents are all made of premium perfume oil – similar to what you find in your favorite designer perfumes.

Is Hyascent pet-friendly?

Our scents are not made of essential oils, rather they are made of fragrance oil. Because our diffuser is completely analog, there are no warming effects or water misting effects to interact with the oils as in traditional electric water diffusers. The hourglass design keeps oil contained inside and its wide, heavy base makes it sturdy. For extra precautions, we recommend keeping the diffuser out of your pet's area and not touching the wood core. Check in with your vet if you'd like advice personalized for your pet.
