The Diffuser That Actually Works.

Stop masking odors. Laylia eliminates them. Pure essential oils, no water, no compromise. Your space finally smells like home again.

Frequently Asked Questions

Does waterless actually work better?
Yes. Water dilutes essential oils and weakens their potency. KOSHI's nano-mist technology atomizes pure oils without dilution, so the fragrance lasts longer and odor elimination is actually effective. You get more mist per drop of oil.
Will it eliminate pet odor?
Yes. Pet odor comes from residue embedded in air and surfaces. KOSHI's nano-mist actively neutralizes it, not masks it. Most customers see results within an hour. Use the high-intensity mode for larger spaces or heavy odor.
How long does the battery actually last?
The 1000mAh battery runs for 12+ hours on a single charge. The smart work/sleep cycle powers the diffuser during the day and goes silent at night to conserve energy. One charge covers your entire routine.
Can I use it in small spaces?
Absolutely. Use the low-intensity mode (5-second spray, 12-minute pause) for bedrooms and bathrooms. For larger living rooms, use high-intensity. KOSHI covers up to 1,000 sq ft depending on the mode you choose.
How often do I need to refill the oil?
The 120ml tank lasts 2–4 weeks depending on the intensity level you use. Unlike smaller diffusers, you won't be constantly refilling. Low-intensity mode stretches it even further.
Is it loud?
No. KOSHI runs almost silently. The nano-mist atomization is whisper-quiet — you won't hear it during sleep or work. The only sound is the faint misting cycle.
Wall-mount or desk — which is better?
Both work. Wall-mount keeps surfaces clear and positions the mist higher for better air coverage. Desktop placement gives you flexibility to move it between rooms. Use the included adhesive hook for walls or set it anywhere on a flat surface.
What oils should I use?
Pure essential oils work best. KOSHI is designed for 100% pure oils without fillers or water. Don't use fragrance oils or blends with carrier oils — they can clog the atomizer. Stick to high-quality essential oils for best results.

    Finally. Odors Actually Gone.

    My apartment reeked of pet smell. I tried everything — candles, sprays, nothing worked. KOSHI eliminated it in an hour. Three months in and the smell stays gone. I'm not going back.

    It Actually Neutralizes, Not Masks.

    I was skeptical a diffuser could eliminate odors. One week and my bathroom doesn't smell anymore. The nano-mist is fine, lasts forever on one charge, and I barely notice it running. Game changer.

    Something That Actually Works.

    My kitchen smells like cooking for days. This clears it completely. Wall-mounted it by the window, set it to high intensity, and the smell is gone by dinner. Worth every penny.
