Question 1

What is Zhithera?

Accepted Answer

Zhithera brings botanical aromatherapy and contemporary home fragrance into everyday spaces. Our collection pairs pure botanical essential oils and designer fragrance oils with waterless, heat-free diffusers, so you can choose the scent that feels right at home, at work or on the go.

Question 2

How are botanical essential oils different from fragrance oils?

Accepted Answer

Botanical essential oils offer distinctive aromas of plants from bright citrus to herbal and floral notes. Designer fragrance oils offer composed scent profiles for your space. Check the individual product description to find your match.

Question 3

How does Zhithera bring aromatherapy and home fragrance together?

Accepted Answer

One device with two oil lines lets you use botanical essential oils for aromatherapy or designer fragrance oils for home scent, swapping pods to change. Zhithera uses Micro-Mesh Atomization without water or heat. Aromatherapy describes an aromatic experience, not a medical treatment.

Question 4

Can I use both essential oils and fragrance oils in one device?

Accepted Answer

Yes. Zhithera's oil-resistant chamber runs both pure botanical essential oils and designer fragrance oils directly — one device, two oil lines. Just swap the pod to change between them.

Question 5

How is a waterless diffuser different from a water-based one?

Accepted Answer

A waterless Zhithera diffuser atomizes pure oil directly with no water and no heat, giving dry micron-fine mist with no tank to empty. A water-based ultrasonic diffuser makes damp vapor from water and a few drops of oil, diluting scent and needing regular rinsing.

Question 6

How do I choose the right scent intensity for my space?

Accepted Answer

Begin with a low, intermittent setting and adjust from there. Room size, ceiling height, airflow, the oil and the output setting all change how noticeable the scent is. In testing, a D1 on high continuous with fragrance oil covered about 380 m² (roughly 4,000 sq ft), an upper limit rather than an everyday setting.

Question 7

Why can't I smell the scent after a while?

Accepted Answer

It's usually olfactory adaptation, not a fault. Your nose filters out a constant aroma, so step out for a few minutes and it typically returns. If the room still smells of nothing when you come back, check the oil level and give the atomizing mesh a light wipe.

Question 8

Can I use Zhithera around children and pets?

Accepted Answer

Every Zhithera oil is backed by a batch Certificate of Analysis (COA) and a Safety Data Sheet (MSDS), so you know exactly what is in the bottle. As with any home fragrance, diffuse in a ventilated room and keep the oils and the device out of reach of children and pets. If you would like the documents for a specific oil, email support@zhithera.net and we will send them over.

Question 9

Where do you ship, and how long does delivery take?

Accepted Answer

We ship worldwide. Delivery times vary by destination and shipping method, and estimated times are shown at checkout. Once your order ships, we email a tracking link, and you can also track it from your account.

Question 10

Can I take Zhithera oils and a diffuser on a plane?

Accepted Answer

Check airline and country rules before you fly. The diffuser's built-in lithium battery meets usual cabin carry-on standards and 10 ml oils are under the 100 ml liquid limit, but must fit within your total liquids allowance. Airport security has final say.

Question 11

Where can I find help choosing oils or caring for my diffuser?

Accepted Answer

Explore the essential oil and fragrance oil collections for scent descriptions, and check your diffuser product page for compatibility and operation. Our FAQ covers refilling, charging, cleaning and troubleshooting. If you still need help choosing a combination, contact Zhithera through the Contact Us page.

Question 12

How small are the D1 and D1 mini?

Accepted Answer

The D1 measures 97 × 43.5 × 24 mm and weighs about 310 g, sized for a desk, nightstand or tote, and its 3,500 mAh base doubles as a power bank. The D1 mini measures 103 × 26 × 20 mm and weighs about 35 g, roughly the size of two lipsticks, so it fits in your palm, a purse or the car.

Question 13

What warranty does the diffuser come with?

Accepted Answer

Zhithera diffusers and charging bases are covered by a 12-month warranty against manufacturing faults (non-accidental). Oil pods, which contain the precision mesh, are consumables and aren't covered once used. If an item arrives faulty (leaking, damaged seal, or no mist when unused), contact us within 15 days of receipt.

Question 14

What do the low, medium and high settings do?

Accepted Answer

On the D1, low diffuses about 10 seconds then rests 5 minutes, medium diffuses about 15 seconds then rests 1 minute, and high runs continuously. On the D1 mini, setting 1 runs continuously, setting 2 diffuses about 15 seconds then rests 2 minutes, and setting 3 is a motion-sensing car mode that wakes on vibration and diffuses about 5 seconds every 2 minutes.

Question 15

Can I use the diffuser in the bedroom at night?

Accepted Answer

Yes, you can use it at night on an intermittent setting. D1 low diffuses about 10 seconds then rests 5 minutes; D1 mini setting 2 diffuses about 15 seconds then rests 2 minutes. Avoid leaving a continuous setting running unattended overnight, and the device does not stop by itself when the pod runs dry.

Question 16

How long does the diffuser run on a full charge?

Accepted Answer

It depends on model and setting. D1 on its powered base runs about a week between charges. D1 mini on a full charge gives about 1.5 hours Continuous Mode, about 13.5 hours Intense Mode, and about 5–7 days daily driving in Car Sensor Mode.

Question 17

Can I use the diffuser while it's charging?

Accepted Answer

Yes, on every model. The D1 can diffuse while sitting on its powered base. A full charge takes around 35 minutes on the D1 and around 40 minutes on the D1 mini over Type-C, and the last couple of percent slow down as the device switches to trickle charging to protect the battery.

Question 18

Do I need to add water to my diffuser?

Accepted Answer

No. Zhithera diffusers are waterless and heat-free — they atomize pure oil directly into a micron-fine mist using Advanced Micro-Mesh Atomization. There's no tank to fill or empty. Just add your oil and switch it on.

Question 19

How do I refill the diffuser or change scents?

Accepted Answer

Open the side fill port, add Zhithera oil and reseal; the pod is refillable. Ease the silicone plug out gently — it is a wear part and a torn plug isn't covered, though the pod works upright. Change scent by swapping pods rather than mixing oils.

Question 20

How often should I replace the oil pod?

Accepted Answer

The oil pod houses the precision atomizing mesh and is a consumable part. With Zhithera oils we suggest a fresh pod after roughly five refills — about 32 ml of oil — which keeps the mist at its finest. In practice pods often last well beyond that, and the moment to change is when output noticeably drops rather than a fixed date. Keeping a spare pod on hand means you are never caught out.

Question 21

How much oil does the diffuser use, and how long does a pod last?

Accepted Answer

D1 uses about 0.14 ml/hour on low, 0.87 ml/hour on medium and 4.3 ml/hour on high continuous. A 6.5 ml pod lasts about two days of everyday use on low. D1 mini uses the same rate while misting, giving about 1.5 hours Continuous Mode, about 13.5 hours Intense Mode and about 37.5 hours active running in Car Sensor Mode, estimates.

Question 22

Can I use essential oils I bought elsewhere?

Accepted Answer

Yes, if the oil is thin and free-flowing. Thick or carrier-diluted oils need thinning with roughly 60-80% alcohol to 20-40% oil, oil at 20% or above, and wipe mesh before and after. Alcohol is flammable, keep away from flame and work ventilated; clogging from non-original oils isn't covered by warranty.

Question 23

How do I clean and maintain the diffuser?

Accepted Answer

Upkeep is minimal: wipe up any spilled oil after refilling, keep the body (and the D1's charging base) clean and dry, and give the atomizing mesh an occasional light wipe with a cotton swab to keep the mist even. There's no water tank to rinse.

Question 24

Can I leave the diffuser running unattended?

Accepted Answer

You can leave it on low or medium intermittent setting. The device does not switch itself off when the pod runs dry, and high setting runs continuously. Switch off or refill promptly once oil is gone and keep it upright on a stable surface.

Question 25

I can barely see any mist. Is it working?

Accepted Answer

Almost certainly yes. The output is a micron-fine dry mist with no water, so it can be close to invisible in bright light. Check for quiet working sound and scent; if neither, work through troubleshooting below.

Question 26

Why isn't my diffuser charging properly?

Accepted Answer

On the D1, make sure the charging base is magnetically seated; the D1 mini has no base and charges straight through its Type-C port. Check that the Type-C cable is firmly connected (the cable is sold separately), try another cable or power source, and keep contacts clean and dry, wiping spills straight after refill. On the D1, a full charge before first use calibrates its battery gauge.

Question 27

My diffuser won't power on. What should I do?

Accepted Answer

Press and hold the power button for about 2 seconds to switch it on. If nothing happens, the battery may be flat — charge it for a while (the D1 on its charging base, the D1 mini through its Type-C port), then try again. The mode buttons only work once the device is powered on.

Question 28

Why is my diffuser not producing any mist?

Accepted Answer

Wipe the atomizing mesh lightly with a cotton swab or tissue. Pressing hard can push the white wick rod out of position and stop mist; if so nudge the rod gently side to side with a dropper while refilling. Check pod seating, oil level and charge, and fit a fresh pod if oil is too thick or mesh is worn.

Question 29

The mist is weak or inconsistent — what could be wrong?

Accepted Answer

Persistent weak output is usually oil residue on the mesh or an oil that is too thick. Wipe the mesh clean and use a pure low-viscosity oil; oils diluted with heavy carrier oils clog the mesh. Over many refills the mesh naturally wears, so fitting a new pod restores full output.

Question 30

The battery drains too quickly. What should I check?

Accepted Answer

If it drains unusually fast, check it charged fully and contacts are clean. D1 runs about a week between charges; D1 mini 420 mAh gives about 1.5 hours Continuous, ~13.5 hours Intense, 5–7 days Car Sensor Mode. First full charge on D1 lets battery gauge read accurately.

Question 31

My diffuser gets warm during use. Is this normal?

Accepted Answer

A slight warmth can be normal, but Zhithera diffusion is heat-free, so it should not get hot. Avoid running the highest, continuous setting with an empty pod — if the oil runs out, switch off or refill promptly. For long, unattended sessions, use a low, intermittent setting.

Question 32

The display or indicator light isn't showing correctly.

Accepted Answer

On D1 standby hides the battery indicator and only the setting symbol stays lit, which is normal. D1 mini shows setting by indicator color and toggles RGB ambient light by pressing power three times within two seconds. If lights still look wrong, fully charge the device then switch it off and on again.
