Purify the Air with 4 Essential Oil Combinations

I’m always looking for natural ways to clean the air in our home. I love my indoor plants for this reason. They brighten my space and help purify the air around us.

Essential oils can give that same benefit! Certain essential oils can reduce the amount of microbes in the air when they are diffused. While researching this post, I found a great article about whether or not essential oils can improve air quality.

Studies have shown oils such as lemon, tea tree, lavender, eucalyptus, and thyme all have this ability. But some studies have also shown that these oils were only effective for the first hour of diffusing. More research is needed. To error on the side of caution diffuse sparingly, for less than an hour at a time. Some oils should not be diffused around children or pets.

These diffuser combinations are for my 120mL diffuser so adjust accordingly for your own. A good guideline is to start with 3 to 5 drops of oil per 100mL of water. It’s always easier to start on the lighter side and add more drops of essential oil if needed. Consider the size of the room you’re diffusing in and who will be in it. We live in a tiny space so a little goes a long way.

Something to Keep in Mind: Diffusing essential oils is one of the safest ways to use them but always be cautious when diffusing around children, pets, and those with asthma or allergies.

Here are four of my favorite diffuser combinations to purify the air:

Diffuser Combination for Purifying the air - lemon and tea tree

2 Drops Tea Tree and 2 Drops Lemon

Both lemon and tea tree essential oils have disinfecting properties that also allow them to clean the air. Lemon also offers a bright uplifting scent and tea tree supports the immune system.

Purifying the air with tea tree, sweet orange, lemon, and bergamot

1 Drop Tea Tree, 1 Drop Sweet Orange, 1 Drop Lemon, and 1 Drop Bergamot

For a stronger citrus variety add sweet orange and bergamot to the lemon/tea tree combination. These promote a positive mood, ease anxiety and create a relaxing calm atmosphere along with the purifying benefits.

Diffuser Combination for Purifying the air - orange, tea tree, and eucalyptus

1 Drop Eucalyptus, 1 Drop Sweet Orange, and 1 Drop Tea Tree

Eucalyptus is a secondary oil for cleaning the air and combines nicely to boost tea tree’s disinfecting power. They both aid the respiratory system. Sweet orange adds a fresh citrus scent and an uplifting quality.

Purifying the air with lemongrass, rosemary, and cedarwood

1 Drop Lemongrass, 2 Drops Rosemary, and 2 Drops Cedarwood

Lemongrass essential oil is recommended for cleaning air pollution as well as disinfecting. I find the scent easily overpowering. Adding rosemary and cedarwood helps mellow it with their woody scents. Cedarwood calms and soothes while rosemary aids focus and promotes alertness.

Synergy Blends:

I have a couple of synergy oils from Plant Therapy that I use occasionally. Germ Fighter and Immune Aid are my favorites to use to clean the air. They also boost the immune system.
