All about air filters


Maintaining clean and quality in a living space is not only important, but also essential. Nowadays, due to constant degradation and pollution, it has become a difficult task to maintain clean air. Even the cleanest of places are likely to have invisible particles and dirt that can negatively impact the health of the inhabitants. This is where air filters come in. They are devices made of porous and fibrous materials to clean the air in a closed space. Air filters are particularly helpful to people with health conditions such as allergies and asthma. Since their inception in the 16th century, air filters have undergone tremendous development. Nowadays, air filters are capable of removing up to 99.9% of dust particles and other impurities. Below are some of the different types of air filters commonly used.

1. Ionic Air Filter
Ionic air filters are also known as air ionizers employ a more complex method than normal filters and rely on voltage to clean the air. Normally, air particles and contaminants are made up of molecules that have a stable charge. Air ionizers produce negatively charged ions that attract contaminants and particle molecules causing them to become heavier. Due to increased weight, the molecules settle on the walls, ceiling or furniture leaving fewer particles that can be inhaled. The advantage of air ionizers is that they do not have filters that require regular cleaning.

2. HEPA Air Filter
High-Efficiency Particulate Absorbing (HEPA) filters are among the commonly used air filters. They are said to be more effective than ionic filters and are recommended for sensitive applications. HEPA filters are extremely effective in cleaning the air since they can remove 99.97% of dust particles and contaminants from the air of up to 0.3 microns in size. They are composed of fiberglass mats that trap particles. The effectiveness of the HEPA filters depends on the quality and diameter of the filters. HEPA filters work in three different ways that include interception, impaction, and diffusion.

3. Carbon Air Filter
Carbon air filters use chemical adsorption to eliminate impurities in the air. Carbon is used to neutralize the contaminant and dust molecules as air flows through the filters. They can also be enhanced for the carbon to even trap chemical compounds and gases. The filters are ideal for living spaces where chemicals must be removed.

4. UV Light Filters
UV light filters are the fourth most commonly used filters. They rely on the reaction that occurs when titanium dioxide is exposed to UJV lights to neutralize impurities in the air. High-intensity UV light filters are effective since they can break down most carbon-based molecules. However, the effectiveness depends on the amount of time the air is exposed and the intensity of the UV light.
