4 Best Filterless Air Purifier (June 2019)

You want to feel safe in your living space knowing that you are away from the countless contaminants that plague the air outside, but unfortunately, such conditions are not guaranteed. That’s where air purifiers come in. Unlike other air purifiers, as their name suggests, a filterless air purifier does not employ any filters to aid their air purification process. The filterless air purifier has several benefits including saving you the money you would otherwise spend in replacing an expensive filter every now and then. They are also relatively cheaper than other filters. Many consumers automatically associate air purifiers with air filters, as most models usually sport at least a filter or two to back up their air cleaning claims. There’s a small niche of air purifiers, though, that take pride in being filterless.

How Filterless Air Purifier works

It’s vital to understand how filterless air purifiers work so that it’s easier to determine which air purifier is best suited for you. Filterless air purifiers rely upon the following technologies: electrostatic precipitation, ozone, photocatalytic oxidation, ultraviolet light, ionization, and thermodynamic sterilization.

These technologies include:

  • Photocatalytic oxidation, which converts gaseous pollutants into harmless compounds through titanium dioxide and UV-C
  • Ionization, which generates ions which help weigh down or trap pollutants. Removes airborne particles without a filter and remains cool. These type of filterless air purifier have no method to kill the bacteria. These filterless air purifiers are more expensive.
  • UV-C light, these type of filterless air purifier use ultraviolet light to obliterate microorganisms. Instead of using filters, they use ultraviolet rays to kill bacteria. They also eliminate the worry of dirty particle buildup on the filter. UV air purifiers are tremendously more energy-efficient than other air purifiers because instead of having to rely on a steady flow of air that requires filtering, this filter-free air purifier does not need to draw the air into the device. 
  • Thermodynamic sterilization, where microorganisms and proteins are exposed to heat to destroy them. These filterless air purifiers are extremely effective at killing bacteria. These filterless air purifier are less expensive and affordable. But these generate heat and keep it’s surrounding a little warm.
  • Ozone generation, which can neutralize strong odors but can also be potentially hazardous as these release ozone. These type of filterless air purifier use ozone or some sort of combination of oxidizers that clean air and are filter-free. These are typically more effective when used simultaneously with other purifiers. They also work best for microorganisms, such as mold or mildew. These more advanced filterless air purification systems are seemingly much more efficient and effective in the work they do than other air purifiers.
  • Electrostatic precipitation, which is similar to ionization in that it charges pollutants and uses oppositely-charged metal plates. These type of filterless air purifier are highly efficient devices that remove dust particles in the air by using a high-voltage electrostatic charge; these particles are then accumulated on charged plates. The plate contains a row of thin wires, and these devices usually have large metal plates placed vertically.

The most popular models, however, work through either ionization or thermodynamic sterilization.

Pros and Cons of Filterless Air Purifier

ProsCons
