Over the past few years, we’ve all become more aware of the air we breathe — both outside and inside our homes. While the pandemic may no longer be a global emergency, indoor air quality remains an important part of keeping your household healthy and comfortable. Our homes are meant to be a safe haven — but the air inside can sometimes be more polluted than the air outdoors. So, what can you do to make sure the air in your home stays clean, fresh, and healthy? Let’s talk about indoor air purification.

What About Indoor Air Purification?

To be clear, air purification is not a substitute for regular cleaning and sanitizing. However, air purification helps remove airborne contaminants that traditional cleaning cannot — things like dust, pet dander, pollen, smoke, and even microscopic particles that affect breathing and comfort.

All air contains tiny particles, but indoor air can become trapped with these irritants over time. For those with allergies, asthma, or other respiratory sensitivities, this can make a big difference in daily health and comfort. Here’s how various types of air purification systems work to keep your indoor air cleaner.

Types of Indoor Air Purification

1. Air Filters

Air filters are the most basic — and essential — form of air purification. Filters have ratings such as MERV and MPR, which indicate the size and type of particles they can capture as air moves through your HVAC system.

Smaller particles like bacteria and viruses are often too fine for standard filters to catch. However, it’s important to note that your HVAC system needs sufficient airflow to function properly — so while stronger filters trap more particles, they can also restrict air circulation if not properly matched to your system.

2. UV Lights

UV (ultraviolet) lights kill microorganisms such as mold, bacteria, and viruses. When installed within an HVAC system, UV lights target the air as it circulates through the return ducts. Their effectiveness depends on exposure time — how long the air is in contact with the light — and coverage area. Not all indoor air passes through the ducts, so UV systems are most effective as part of a layered purification approach.

3. Ionized Hydrogen Peroxide Air Purification Systems

These advanced systems release hydrogen peroxide plasma charged with positive and negative ions (a process known as bi-polar ionization, as used in systems like the RGF HALO-LED). The charged plasma acts like a magnet, bonding to airborne particles and microorganisms in the air and on surfaces. According to the CDC, hydrogen peroxide is safe and effective for killing harmful microorganisms such as viruses, fungi, and bacteria. As the plasma attaches to airborne particles, it causes them to cluster and become heavier — making them easier for your air filter to capture. Many systems, like the HALO-LED, also include an internal UV or LED light for added protection, killing any remaining microorganisms in the ducts.
