Air Purifiers: Terms to Know

Before we get started, there are a few key terms you should know to fully understand how each product compares. To that end, you’ll want to familiarize yourself with these short definitions:

  • HEPA Filter: This type of filter is very dense and traps 99.97% of the smallest sized particles (o.3 microns), such as dust, allergens, smoke, and fine particulate matter (PM2.5). It’s considered the best type of filter for improving air quality.
  • Activated Carbon Filter: This filter absorbs odors caused by pets, cooking, mold, chemicals, smoke, and other things that produce smells inside the home.
  • Ionizer: This technology emits ions into the air that attack pollutants. Instead of collecting particles into a filter like a HEPA device does it causes the particles to fall onto the ground. Some ionizers do include an electrostatic collection plate that will attract the particles onto it.
  • PlasmaWave Technology: This is a safer form of ionization. It uses water vapor to remove airborne pollutants air as opposed to ions like an ionizer.
  • Ultra Violet (UV-C) Light: This safe spectrum of light kills airborne particles such as bacteria and viruses, creating a sterile germ-free home environment. It’s an good feature to look for to protect your health.

Frequently Asked Questions (FAQs) About Home Air Purifiers

What is a true HEPA filter?

Each of the top 10 air purifiers on this list includes a True HEPA filter.

HEPA stands for “high efficiency particulate air” and it’s one of the most powerful technologies for cleaning the air around you.

Adding the word “True” on an air purifier claims it to have the highest class of HEPA filtration. A True HEPA filter can capture 99.97% of particles down to 0.3 microns.

Inside a HEPA filter, you’ll find a very dense and seamless sheet of fibers that are pleated like an accordion.

Under a microscope, you would see that these fibers are various sizes and woven into a felt-like net. This design is what allows HEPA filters to capture airborne particles.

When a this filter is classified as a True HEPA filter, it means that the air purifier is able to trap the finest particles possible, down to 0.3 microns in size, and at a 99.97% success rate.

Inside of an air purifier, you’ll find a fan which pulls air through it from one side and expels it out the other.

As air passes through the HEPA filter, microscopic particles such as pollen, mold, bacteria, pet dander, fungi, smoke, etc. get trapped in the fiber mesh. The result of that process pushes clean, fresh air out the other side of the filter and back into the air for you to breathe.

The only downside to these filters is that they can’t eliminate odors — which is where activated carbon filters come into play.

What is an activated carbon filter?

Another filter that’s included in each of the top air purifiers listed above is an activated carbon filter, also known as a charcoal filter. These pick up where HEPA filters leave off by absorbing odors from smoke, pets, cooking, mold, and other common sources inside the home.

The charcoal inside these filters is activated which means that it has been treated with oxygen in order to expand the surface area of the carbon atoms. This process causes the charcoal to become extremely porous and absorbs particles that cause odors.

Similar to how a HEPA filter works, a fan inside the air purifier must draw air through the charcoal filter in order for it to trap odor particles as they pass through.

The toxins become attached to the surface of the charcoal and are unable to return back into the air. This removes odors from the room and neutralizes them inside the air purification machine.

EPA on Air Quality and Air Purifiers

Air Purifier Reviews WindowThe Environmental Protection Agency (EPA) reports that indoor air — where we spend more than 90% of our days — is often two to five times more polluted than outdoor air.

The EPA suggests that the most effective way to improve indoor air quality and health is to reduce or remove the source of contaminants.

However, that’s not always possible, nor do we always know where the pollutants are coming from.

As an alternative, the EPA suggests using a portable air purifier and/or upgrading the air filters in your HVAC system.

The benefits of using an air purifier is that they can focus on a single room or area of your home to keep airborne pollutants out at a much more affordable price than upgrading an entire HVAC system.

Top Air Purifier Brand Considerations

When choosing between the best air purifiers on this list, keep in mind that every person’s experience will be different.

Although an air purifier claims that it’s better than other brands, you have to really do your research to confirm these claims.

According to Rachel Rothman, chief technologist at the Good Housekeeping Institute, ”The effectiveness of air purifiers in real-world situations likely won’t mimic those of controlled conditions in a lab.”

That means it can be difficult to measure how effective an air purifier actually is in your home environment, so keep this in mind as you do your research.
