What to look for when buying the Best Filterless Air Purifier

Before purchasing a filterless air purifier, there are considerations to be made. Some tips to identify which air purifier will work best for the space you intend to use it for.


Whether or not it can cover the space you are looking to cover, the coverage area is a key feature to consider when you buy a filterless air purifier.
This number actually shows you the size of the room in which you can use the filterless air purifier. Keeping at or below the coverage area makes sure the filterless air purifier will work excellently. Filterless air cleaners available on the market have different coverage areas – designed for different room sizes – ranging from 100 sqft to 1000 sqft.

Size & Dimensions

The size of the purifier for portability. the dimensions of any filterless air purifier are one of the primary features to be taken into consideration when you want to ensure that the product will fit in the space you have. For example, a large unit will not fit into a small room. So, you must measure the space first and then try to find a filterless air purifier with dimensions you prefer.

Noise Levels

The level of noise a filterless air purifier makes is another feature you need to consider. You must choose a filterless air purifier unit that barely makes a sound or performs a completely silent operation. Most filterless purifiers don’t make any sound at all – e.g. Onix3000 and Air Oasis 1000G3. Other models or units can make 5 dB to 50 dB noise. The lower the noise level in dB, the better.


The warranty of the product protects you from different kinds of issues with a filterless air purifier. A filterless air purifier may have manufacturing errors or defects in parts. Therefore, make sure you check the warranty of the product from the manufacturer. A two-year warranty – for instance, offered by Onix 3000 – gives the user a bit of extra time to check and test the product to ensure there are no problems to deal with.

Ozone production levels

The amount of ozone the machine creates and if it has a deactivation option for it as do some other air cleaners with conventional filtration systems.

Energy consumption

How much it costs in maintenance and the energy consumption it uses in the different setting modes considering you may want to be leaving on these machines all day long during certain events such as spring time or when mold has appeared in an area you need to clear..

Considering these factors will help you choose a purifier that will accurately meet your needs.

Types of Filterless Air Purifiers

As mentioned above, taking the cleaning method of your air purifier is very important in choosing a purifier that will appropriately satisfy your needs. There are three main types of filterless air purifiers.

  1. Ozone Generators, otherwise called Ionizers.
  2. Ultra-violet Light Purifiers and
  3. Electrostatic Precipitators.

Among these three types, two are more predominant – the Ionizers and the UV Light Purifiers. Below, we shall discuss these two purifiers and how they work. Understanding how they work plays an important role in choosing your preference.

What is UV Light Air Purification and How does it work?

As a result of scientific research, it was discovered that UV light is detrimental to various micro-organisms. These include viruses, bacteria, mold spores, and other germs. As a result, this technology has been adapted as an air purification system. As the air purifier sucks in air found in the room, the UV light kills the pathogens found in the air before releasing the purified air clear of all unhealthy particles and allergens.

What is Ionic Air Purification and How does it work?

Ionic Air Purification uses an electronic charge to remove or add electrons from or to oxygen atoms. They are particularly good at removing airborne particles as the negative ions they emit bond with various air particles making them heavy enough to drop to the floor. They are also good at removing germs, bacteria, mold spores and other micro-organisms from air. Ionic Air Purification is also efficient at removing bad odor so as to make air quality better.

Electrostatic precipitators remove suspended particles from the air by applying high-voltage electrostatic charges to collect dust particles on charged plates.
Photocatalytic Oxidation (PCO) is an air purification technology, which can destroy pollutants as tiny as 0.0001 microns. Used to destroy microorganisms, VOCs and CACs.
Used by the Airocide APS-200 air purifier
Thermodynamic Sterilization (TSS) is a purification system that uses heat sterilization through a ceramic core to heat with microcapillaries at 200 degrees centigrade.
Used by the Airfree Air Purifier Onix-3000
“Oxygen Plus Technology” can turn ozone and smog into pure oxygen
Used by the Envion Ionic Pro uses it.


Other advantages of Filterless Air Purification

Apart from the obvious advantage of filterless air purification which is clean air, there are other advantages that come with using this method of purification. These include the following:

Reduced stress and low cost of maintenance

Air purifiers that use filters require that you constantly remove and clean or change the filters in order for it to work efficiently. With filterless air purification, the constant cleaning and maintenance of filters is reduced significantly. This in turn reduces cost associated with cleaning and maintaining the filter

Reduced noise levels

Because of the absence of a fan, filterless air purification is noise-free. The sound it produces is actually more soothing than disturbing. Even at a high velocity, the noise produced by filterless air purifiers is very low as compared to HEPA air purifiers.

Key Features to look out for when buying an Air Purifier

  • Our checklist includes when choosing an air purifier.
