If you wonder how Air Purifiers clear allergens, remove dust, pet danders, and smoke, etc. from the air, then you’re reading the right article. We provide you with all the information you need to know how Filters, UV light, Ionizing, Adsorbent, and Ionizing air purifiers work.

How Air Purifiers Work

Air Purifiers use filters to clean the air. They make are among the most crucial parts of cooling or heating systems in most homes.

Filters use synthetic fiber/fiberglass, cotton and foam to clean air. To boost the efficiency of these filters, they’re made from high-density materials to filter very tiny air particles.

Pleated air filters purifiers have the best capability because of the increased surface area to trap foreign particles.

Here are the common types of air purifiers and how they work:

1. UV light Air Purifiers

These air purifiers pass ‘dirty air’ through ultraviolet rays to sterilize harmful microorganisms in the air.

2. Ionizing Air Purifiers

These air purifiers use a corona discharge method to produce ions. Note that air atoms are neutrally charged.

On the contrary, the corona discharge has an intensely charged electrical field. When the air particles are passed through this medium, they get charged and a molecule to give them a negative charge is added.

Optionally the medium can also remove an electron from the air molecules to give them a positive charge. This way, the large air particles passing through the corona discharge medium are ionized.

When released the air particles pass through two metal plates with positive, and negative charges in the system. This ensures the resultant air particles have negative and positive charges to ensure they attract to one another, collect and get discarded.

3. Adsorbent Air Purifiers

Have built-in adsorbent materials to absorb foreign materials like dust, smoke, chemicals, and odors. They commonly use activated charcoal as an adsorbent. The charcoal particles are highly porous, with large surface area something which makes trapping the large dirt particles easier.

4. Ozone Generator Purifiers

These purifiers are engineered to break the second oxygen molecules and ionize them to ozone molecules. They operate like ionizing air purifiers.

Note that oxygen is made up of double molecules. Exposing the oxygen atoms to a corona discharge medium/UV light breaks a particle from the double molecules into individual oxygen atoms.

These atoms collect to form ozone, though most of them collect back to form double oxygen molecules. The efficiency of these purifiers is based on the argument that the ozone cleans up air.

Conclusion

Air filters plays a vital role in cleaning air in our homes. It’s however worth noting that in the cleaning, other substances like carbon monoxide can be heard to eliminate. Therefore apart from purifying the air, it’s critical that you observe hygiene in the homes to keep off highly volatile contaminants which could pass through these purifiers.
