We all want to breathe clean air at home to keep our families comfortable and healthy. An in-duct air purifier can be just the solution you need, but how do you know if it’s right for you? 

What is an in-duct air purifier?

In-duct air purifiers are air purifiers installed entirely within your home or business’s existing ductwork. Your system (furnace or air conditioner) must be running to benefit from this type of air purifier.

These systems do not simply filter the air—that step has already been taken care of by your HVAC system’s internal air filter. An air purifier neutralizes dust, dander, dirt, pollen, and germs using the power of UV light and ionization technology.

How do in-duct air purifiers work?

An in-duct air purifier, like the REME Halo Unit, is installed in your unit’s ductwork to remove dust, mold, bacteria, and viruses before they begin circulating throughout your home. Installing an in-duct air purifier is a simple step to restore your home’s air quality and ensure your family stays healthy and safe. 

Air purifiers contain fans that suck dirty, contaminated air into the unit. Before the air exits the purifier, it is pushed through filters that are interlaced with fibers. When the air is pushed through these mesh filters, harmful particles like smoke and bacteria are trapped. 

Clean air then exits the unit to be circulated throughout your home. This constant filtration process significantly improves your home’s indoor air quality and can help prevent allergies and illness for your family. That’s why it is important to invest in an air purifier proactively.

Types of in-duct air purifiers

There are two key types of in-duct air purifiers: 1. UV air purifiers and 2. ionization air purifiers.

UV air purifiers

You’ve heard that sunlight can kill germs, right? UV air purifiers aim to replicate this process in a closed and controlled environment using UVV and UVC rays. A UV air purifier uses UV rays to neutralize harmful particles that pass through the air duct. Because air streaming through a home’s ducts has already passed through a filter, this method is predominantly used to neutralize germs, odors, and very small particles that can pass through a common HVAC filter.

Ionization air purifiers 

Ionization air purifiers clean the air by electrically charging air molecules so that they bond with positively charged particles—including dirt, dust, smoke, soot pollen, and germs. When the particles bond, they become heavy and fall onto the ground or a nearby surface, allowing them to be swept or vacuumed up over time.
