Air Purification Systems: Choosing the Right Solution for Your Home

There’s nothing like having a clean, fresh home, all day, every day, without worrying about it being too stuffy, humid, dusty, or with weird odors. However, it takes a good air purification system to achieve this. 

Maintaining indoor air quality is essential for a healthy home. Many homes contain airborne pollutants such as dust mites, pet hair, mold spores, bacteria, and other compounds, which can contribute to health risks like asthma attacks, chest pain, and respiratory issues.

Air purification systems help combat indoor air pollution by removing airborne dust, gaseous pollutants, and smoke particles while improving the overall efficiency of your HVAC system. This guide will explore the various types of air purification systems, their benefits, and how to choose the right one for your home.

Understanding Home Air Purification Systems

Air purification systems come in various forms, each designed to improve indoor air quality by reducing or eliminating harmful particles and pollutants. These systems work in different ways, including filtering airborne contaminants, neutralizing germs and bacteria, or improving airflow to help ventilate indoor spaces.

Understanding the key functions of air purification systems can help homeowners make informed decisions about the best option for their needs.

What Does an Air Purification System Do?

Air purification systems remove airborne contaminants through filtration, ionization, or germicidal irradiation. The three main processes include:

• Filtering: Traps particles using air filters (HEPA, carbon, pleated filters, etc.).
• Purifying: Neutralizes contaminants using UV light, photocatalytic oxidation, or electrostatic precipitators.
• Ventilating: Increases airflow to dilute indoor pollutants and improve overall air circulation.
• Defining MERV Ratings: You’ll see something called MERV values in many filters, which stands for “minimum efficiency reporting value.” It measures just how effectively different types of filters trap particles as air passes into portable air cleaners or HVAC systems. The higher the MERV number is, the more efficient the filter material is at trapping fine or ultrafine particles.

Whole-Home Systems vs. Portable Purifiers

• Whole-home air purification systems integrate with HVAC systems and continuously clean the air throughout the house, providing a seamless solution for improving indoor air quality.
• Portable air cleaners target specific rooms and are ideal for apartments, rental homes, or smaller spaces where whole-home solutions may not be feasible.
