Everything You Need to Know About Filterless Air Purifier

Here are some useful explanations to help you better understand what makes a non filtered air purifier different and safe.

How do these type of purifiers work if they don’t have filter?

A filterless air purifier is a machine that directly disables allergens and irritants in the air of a certain amount of area. There are three types which are air quality ionizer type, electrostatic precipitator type.

The first type works by having two separate electrically charged plates: one attracts and disables the contaminants by sucking the air via a fan while the other one charges all particles going in which cleans it. The second one is a more powerful type compared to the first while the third type uses UV light to kill germs, bacteria, viruses, and mold spores.

What is the difference between filterless and filter air purifier?

Simply, a filtered air purifier works better in purifying the air that its filterless counterpart.

A filtered air purifier by sucking in the air. This filtering it using a filter and releases back the clean air. It is more efficient and powerful than its filterless counterpart since the contaminants are physically removed.

As said earlier, a filterless air purifier removes the contaminants electrically which sometimes do not catch the smaller contaminants. Unless the filter is washable and reusable, you need to replace the filter now and then just like an air conditioner or a vacuum machine. This requires more maintenance and is more costly than a filterless air purifier.

Is a filterless air purifier safe?

Yes. While not as efficient as a filtered air purifier, a filterless one still does its job in removing airborne pollutants using a low cost, low maintenance, and compact machine.

If you are looking for an air purification machine for a smaller room and do not want to overspend, a filterless air purifier is your option.
