An important health factor is that your indoor air should be unpolluted and free from dust contaminating particles. To keep it clean you need to look for air purification systems. One of the widely used purifiers is the filter-less air purifiers.

These filter-less air purifiers are also known as active because of their working mechanism which involves cleaning the air from outside rather than the traditional air purifiers that use filters to clean the air from inside. Air purifiers that use filters are known as passive because of their mechanism by which they clean the air by drawing it into the purifier and then filtering it before pushing it back into the room.

Filter-less air purifiers or also known as filterless air cleaners are further divided into four types based upon their working.

  1. Electrostatic Precipitators
  2. Ozone-based Air Purifiers
  3. More Advanced Filter-less Air Purifiers
  4. Ultraviolet Air Purifiers

People usually get confused between air purifier vs air ionizer. Let us talk about these filterless air purifier types in detail.

Electrostatic Precipitators

The electrostatic precipitator works using the mechanism of the electrostatic charge. They remove the dust particles from the air using a high-voltage electrostatic charge. As dust particles get charged they can easily be attracted to charged metal plates that come within these purifiers. These plates are metal plates designed to force the dust particles to themselves resulting in clean air.

Ozone-based Air Purifiers

This type of purifier uses only ozone to clean the air. As this is one of the filter-less air purifiers, its ozone does all the cleaning work for it. Ozone oxidizes the air to remove dust particles from the air. Moreover, it kills germs and microorganisms such as mold, etc. These purifiers are very efficient and effective than any other type of purifier.

Ultraviolet Air Purifiers

As the name indicates that these purifiers work using ultraviolet rays to clean the air and kill microorganisms. Also, these UV rays can kill bacteria. These types of purifiers are efficient as they do not need to draw air into the purifier itself and then clean it rather it uses ultraviolet rays to work directly on the air outside. Moreover, these purifiers don’t use any filters so there is no need to worry about the dust residing on the filters after the cleaning procedure is completed.

Advantages of Using Filter-less Air Purifiers

  • One main advantage of using these filter-less air purifiers, or also known as, air purifiers without filter, is that you need not worry about the cost or cleaning of the filters on a regular basis. So it eventually costs less than the purifiers that use a filter.
  • Cleaning or removing the dust is easy as these purifiers have an electrostatically charged plate that collects dust particles and pollutants from the air. These plates can easily be cleaned therefore consumers love this type of purifier as there is no hectic work to do. Simply take out the plates and clean them without any struggle.
  • It is useful to remove allergens and many other pollutants from the air using a very simple mechanism. These allergens and dust particles are made up of positively charged ions. These purifiers emit ions that are negative so that they form a bond with the particles in the air. When a bond is formed, these particles become heavy and they can’t stay in the air for a longer period so they fall onto the floor from where they can easily be vacuumed or cleaned.
