What Are The Different Purification Technologies?

Ever wondered what are the different purification technologies and why is it even important?

Air purifiers aren’t all the same. They may have the same outcome (they remove particles from the air in an indoor environment), but the technologies behind their functioning can be different depending on the brand and model.

When we know about the different technologies, we discover that the outcome is not actually always the same: for example, some air purifiers only deactivate pathogens, while others took particles away from the flow of air.

Let’s take a look at the different air purification technologies so that you can understand what works better for your needs.


Air Purifier: How Does It Work

An air purifier sucks the air in the device. Inside the device, the air flows through the filters and then is blown back into the room. All air purifiers work like this, but the type of filter may change.

Filters can be based on different materials and technologies: their technology is the main difference between one air purifier and the other.

1) Ionic Purification

Ionic purification utilizes ionic filters. These filters are capable of charging the ions negatively.

When this happens, air particles are attracted by static electricity and remained “glued” to the ionic filter. This way, when the air is blown back into the environment, it is purified.

Ionic filters need to be regularly maintained. When the air purifier’s filter system tells you so, it’s important that you replace the filter as soon as you can.

The main advantage of an ionic purifier is that they are quite cheap. The main disadvantage is that they are not the most effective.

2) Carbon Filters

If you want to go even cheaper, opt for carbon filter air purifier. Carbon filters purify air because the pores of the carbon retain a lot of particles from the air that blows through them.

Again, the fact that they are cheaper has a downside: carbon filters and air purifiers aren’t the most effective.

3) UV Filters

UV filters don’t remove anything from the air that flows through the filters. They work in a different way: inside the device, there are UV lamps.

The air passes through a chamber that is, therefore, enlighted with UV rays. UV light is capable of killing pathogens and microorganisms.

These particles aren’t, therefore, removed from the air, but killed, deactivated, and made unharmful.

4) HEPA Filters

HEPA filters are the most expensive. This may seem like a disadvantage but the advantage that comes with them is that they are highly effective.

In fact, HEPA filters are the absolute best filters you can have on your air purifier. They remove over 99% of microorganisms of different nature from the air.

Conclusion

Sometimes, air purifiers have a double filter system to be 100% effective. One of the most common combos is the one that includes a HEPA filter plus UV lamps: this would be the absolute best, and most expensive, air purifier you could get.
