Frequently asked questions
How often should I refill my reed diffuser? ▼
Reed diffusers typically last 1–3 months depending on room size and ventilation. In Pakistan’s warm climate, oil evaporates faster — especially in summer. Flip your reeds every 1–2 weeks to refresh the scent. A 100ml bottle usually lasts 4–8 weeks in a bedroom-sized room.
Can I use any oil in an ultrasonic diffuser? ▼
No — always use water-soluble aroma oils or pure essential oils in ultrasonic diffusers. Fragrance oils designed for reed diffusers are too thick and can damage the diffuser’s membrane. AromaLab’s ultrasonic oils are specifically formulated to be water-soluble.
How much oil do I need for a large space like a hall or office? ▼
Large open spaces (1,000+ sq ft) require either a nebulising diffuser or multiple reed diffusers placed strategically. A single 200ml reed diffuser covers up to 300 sq ft effectively. For commercial spaces like restaurants and hotels, we recommend our B2B scent system consultation — contact us for a free assessment.
Does Pakistan’s heat affect diffuser performance? ▼
Yes — Pakistan’s high summer temperatures (35–45°C) significantly accelerate oil evaporation in reed diffusers. In summer, expect 30–40% faster consumption. Use fewer reeds (3–4 instead of 6–8) and choose a smaller bottle. Ultrasonic diffusers are actually less affected by heat since you control output directly.
