Natural Air Freshener Guide: Sachets, Sprays & Diffusers

A natural air freshener scents the air with plant material or essential oils rather than synthetic fragrance. Common types are dried lavender sachets, water-based essential oil room sprays, reed diffusers, aroma stones and soy wax melts. At Lavender Backyard Garden®, every air freshener is made from Lavandula × intermedia 'Super' grown spray-free and steam-distilled on our farm in Newstead, Waikato, New Zealand.

Our lavender sachets stay fragrant for more than three months. Because the buds are air-dried, the essential oil stays inside them and is released slowly. The scent fades faster in open air, so when it softens, give the sachet a gentle squeeze and the scent comes back. Keeping sachets in a closed drawer or wardrobe helps them last longer.

Lavender's scent comes from essential oil, rich in linalool and linalyl acetate, stored in tiny glands in each flower bud. We harvest our 'Super' lavender in early February in the Waikato, when the buds hold the most oil, then air-dry the bunches on the farm instead of using heat. Gentle air-drying keeps the oil sealed inside the buds, so it is released slowly over many months.

A room spray is designed to freshen the air quickly, so a few sprays scent a lounge, bathroom or office in seconds. A linen spray is designed for fabric: you mist sheets, pillows, curtains or towels lightly from about 30cm away and let them dry, and the scent stays in the fibres. All our sprays are water-based, scented with essential oils and plant resins, and never synthetic fragrance, so many customers use them both ways.

It depends on the room. A reed diffuser gives a steady, continuous scent with no effort, which suits hallways, bathrooms and entrances. A room spray gives an instant burst when you need it, such as before guests arrive or after cooking. Many homes use both: a diffuser for a constant background scent and a spray for quick refreshes.

Our lavender sachets contain only dried lavender, our herb sachet adds dried eucalyptus and rosemary, and our sprays and diffusers are scented with essential oils, never synthetic fragrance. Even so, essential oils are concentrated, so keep bottles, diffusers and aroma stones out of reach of children and pets, and do not spray directly onto skin or animals. Cats can be especially sensitive to essential oils, so use diffusers in well-ventilated rooms and ask your vet if you have concerns.

Yes. Every Lavender Backyard Garden® air freshener uses Lavandula × intermedia 'Super' grown spray-free on our farm in Newstead, near Hamilton in the Waikato. We air-dry the buds for our sachets and steam-distil the essential oil on-site for our sprays, reed diffuser, aroma stones and wax melts. We do not use imported lavender oil.

In a damp New Zealand winter, wardrobes and linen cupboards can start to smell stale. Air them out on dry, sunny days, make sure clothes are fully dry before you put them away, and leave a little space between items. Then tuck lavender sachets into drawers, hang one in the wardrobe for a gentle, lasting scent, and mist a linen spray over stored bedding when you take it out. A sachet will not fix a damp problem on its own, so deal with any moisture first.

A vent clip diffuser with real essential oil is the easiest natural option, because the air from the vent carries the scent through the car. Our lavender car diffuser holds a fibre stick soaked in lavender essential oil steam-distilled on our Waikato farm, with no heat, plug or batteries. For cars without vent clips, a felt ball keyring diffuser, an aroma stone or a eucalyptus, rosemary and lavender sachet works well too. See all options in our car air freshener collection.

Each refill stick is strongest for the first few days and softens over about 2 to 4 weeks, depending on how often the vent is on. In a hot car during a New Zealand summer the oil evaporates faster, so you may need a fresh stick sooner. Refill sticks are sold singly or in packs of five, and the oak or aluminium clip is reused.

Yes. We make our air fresheners on our farm in the Waikato and send them by tracked courier across New Zealand. Delivery is free on orders of $85 and over. Orders usually arrive in 3 to 5 working days in the North Island and 5 to 7 working days in the South Island and rural areas.
