Different air purifiers use different methods to remove pollutants, such as chemical reactions or filters.

Air purifiers can be used in homes, office buildings or even inside your car. Air purifiers can reduce many common indoor air problems such as smells, smoke, dust and pet allergies. They can also help to reduce the spread of germs and viruses.

There are several different types of air purifiers on the market. Some work better than others at removing specific types of pollutants. It is important to do your research before purchasing an air purifier to ensure you get the best one for your needs.

How Does an Air Purifier Work?

Air purifiers work by removing contaminants from the air. They use filters to capture dust, pollen, smoke, and other pollutants. The filters trap the particles in the air and prevent them from entering your lungs.

Types of Filters in Air Purifiers

Pre Filter- The pre-filter is the first line of defense against dirt and debris in the air. It is located at the front of the purifier and is designed to remove large particles from the air.

Primary Filter- The primary filter is located after the pre-filter and is designed to remove smaller particles from the air. It is also the first step for removing gases and odors from the air.

Activated Carbon Filter- Located after the primary filter, the carbon filter is designed to remove harmful gases and odors from the air. It is also effective in removing smoke and particles from the air.

HEPA Filter- The HEPA filter (high efficiency particulate air) is the final stage in the air purifier and is designed to remove the smallest particles up to 0.3 microns from the air. It is also effective in removing allergens and other harmful particles and provides clean air.

What is an Oil Diffuser?

What is an Essential Oil DiffuserAn oil diffuser (Essential oil diffuser) is a device that disperses essential oils into the air. This can be done in a number of ways.

For example, burning a diffuser on a candle, using an atomizer on a bottle of essential oils or heating the oil in a dish.

People often choose to use an essential oil diffuser because the oils can help improve mood and create a relaxed atmosphere. Some diffusers also have lights attached to create a calm and soothing atmosphere.

How Does an essential oil diffuser Work?

Understanding how an essential oil diffuser works are first important to understand essential oils. Essential oils are natural compounds found in seeds, bark, stems, roots and flowers of plants. Plants produce essential oils to attract certain insects for pollination purposes.

The compounds can also profoundly affect people who use the oils for stress reduction, boosting mood and even improving athletic performance.

Nebulizing diffusers- work by breaking the oil into tiny particles that are then dispersed into the air. The diffuser uses a fan to send the oil into the air, where it is inhaled.

Ultrasonic diffusers- are unique in that they produce cool mist without any heat. This means the compounds are not broken down and remain in the purest form. The ultrasonic diffuser works by vibrating the water at a high frequency, creating millions of tiny bubbles.

The oil is added to the water, and the combined mixture enters the diffuser. Here in the diffuser, it is vaporized into a mist.

Heat essential oil diffusers- Also called oil-burning diffusers, use a lightbulb to heat the oil-producing and aroma that can be smelled in the room. Each oil has a different boiling point, and the temperature must be monitored to ensure that it remains its purest form.

Steam diffusers- also called steam vaporizers, work by adding water to a heated reservoir until it becomes steam. The steam rises through the diffuser and absorbs the oil before rising into the air.

Benefits of Essential Oil Diffuser

There are many benefits to using an essential oil diffuser. Some of the benefits include:

  • Improved air quality
  • Relaxation and stress relief
  • Improved mood
  • Improved concentration
  • Increased productivity
  • Enhanced sleep quality
  • Decreased symptoms of allergies and asthma


We recommend using essential oils in a diffuser because it creates an all-natural, calming scent that might help you sleep better. If you’re looking for something more powerful than the air purifier, don’t mind paying the price tag. In that case, we suggest investing in an ionizer or ozone generator instead of either option.
