How Effective Are Air Purifiers? A Portland Tech Answers

Did you know that indoor air can be 2-5x more polluted than outdoor air? With that in mind, air purifiers can be an easy and effective way of helping you improve your indoor air quality by removing contaminants from your air.

However, the effectiveness of the air purifier depends on your indoor air quality goals. Depending on the type of contaminants you’re trying to reduce, certain air purifier types can be better suited for your goals.

To pick the right air purifier for your needs, you’ll want to choose an indoor air quality goal, such as:

Reducing dust, pollen, mold and bacteria in your home

Reducing the gases and odors in your home

In this blog, we’ll walk you through how different air purifier types are effective at reducing different contaminants in your air.

Goal #1: Reducing the dust, pollen, mold and bacteria in your home

Over time, homeowners have focused on making their homes more energy efficient to save money. One way of doing so is by properly sealing windows and doors. Unfortunately, a side effect of super sealed homes is poor(er) air quality. That’s because when air is trapped inside the home, airborne contaminants are also trapped inside the home.

The contaminants that can be trapped inside your home include dust, pollen, mold, bacteria, pet dander, etc. When they have nowhere to go, these airborne contaminants wind up recirculating throughout your home, potentially aggravating those with respiratory conditions like asthma or allergies.

Luckily, you can improve your indoor air quality with HEPA or UV Light air purifiers. These two types of air purifiers trap the contaminants as air is ventilated throughout your home, preventing a significant amount of the contaminants from circulating.

HEPA Air Filters

High efficiency particulate (HEPA) air filters are typically made with interlaced glass fibers. Ultra-fine airborne contaminants end up catching onto the fibers, keeping the contaminants from recirculating throughout your indoor air.

A HEPA filter can effectively trap dust, pollen, mold, bacteria and any other contaminants that are 0.3 microns in size or larger. For reference, a micron is a millionth of a meter and a grain of salt is 40-60 microns. HEPA filters can claim a 99.97% filtration rate of contaminants that are 0.3 microns or larger.

The downside to HEPA filters is that they can restrict airflow. You’ll want to consult an HVAC professional before installing a HEPA filter.

UV Light Air Purifiers

Another effective way of reducing the amount of airborne bacteria and organisms in your home is to use a UV Light air purifier. UV Light air purifiers use a UV-C light to disrupt and kill pollutants.

However, UV Light air purifiers cannot remove airborne particulate matter from your home.

UV/Catalyst Ionizing Hybrid

Hybrid purifiers can remove volatile organic compounds (VOCs) and reduce exposure to many common bacteria, viruses and mold. They can also force smaller airborne particles to clump together, which makes it easier for your filters to catch the tiny particles.

For example, RGF’s REME HALO purifier is a hybrid purifier that has become popular with customers who want to improve their overall indoor air quality and the health of their home’s occupants.

Goal #2: Reducing the gases and odors in your home

Another big focus for indoor air quality improvement is reducing the gases and odors in your home. If your home has a lot of cigarette smoke, cooking odors, or air pollution because you live near a highway or you live in a wildfire-prone area, you might benefit from installing an air purifier that’s effective at reducing gases and odors.

The air purifier type most effective at reducing gases and odors is an activated carbon filter. Activated carbon filters absorb gases and odors through a chemical process called adsorption. Then, the gases and odors adhere to the carbon beds installed within the filters, removing them from your indoor air.

While activated carbon filters are effective at removing gases and odors and can remove particles between 0.5-50 microns in size, they are not effective at removing ultra-fine particles and you’ll want to see Goal #1 for that instead.
