As a homeowner, you probably have to contend with stale air and odors when you’re running the HVAC and your home is closed up tight. You could use air fresheners, but those can result in a chemical smell. Alternatively, you could burn candles, but then there’s the risk of a fire. If you’re looking for a way to give your home a pleasant scent without using chemical-filled air freshener sprays or burning candles, using essential oils in your air filter is the answer.

What Are Essential Oils?

Essential oils are oils made up of compounds that are extracted from plants. Each essential oil captures the scent of and flavor, or “essence,” of each plant. Essential oils are characteristic of the unique aromas of the plants they’re made from. They can be made either through distillation (via either water or steam) or by a mechanical method such as cold pressing the plant.

Essential oils are a safer, more natural alternative to freshly scent your indoor air and avoid the hazardous chemicals released by sprays and candles. The aromatic natural compounds they contain are sourced from plant bark, seeds, leaves, and stems. Along with giving your home a wonderful scent, many oils come with beneficial properties.

How Do I Use Essential Oils in My Air Filter?

Putting an essential oil on your air filter is easy. Follow these steps:

  • Take a fresh air filter that’s the right size and MERV rating to match your HVAC system. If you’re not sure which filter to use, check your equipment manual, or ask for advice from your HVAC pro.
  • Select one essential oil to use, or create your own combination for a unique scent with additional beneficial properties.
  • With an eyedropper, put 15 to 20 drops of oil evenly over the filter surface, then install it in your HVAC unit. With the scented filter in place, a soothing fragrance will be sent out with your conditioned air each time the blower cycles on.
  • The scent will diminish in about 30 days, which is also the ideal time to check your air filter. You can add more oil if the filter is still clean, or scent a new filter if the old one needs replacement.
