Top 5 Best Allergen Removers of 2019: Buying Guide

No matter how much of a neat freak you are, cleaning alone won’t protect you from the airborne allergens that trigger stuffy noses, nagging coughs, and asthma attacks. However, there is an appliance you can use that will greatly reduce the number of indoor allergens in the air – an allergen remover. Here is a rundown of the basics every allergen-remover owner should know.

What Is an Allergen Remover?

An allergen remover, also known as an air purifier, is an appliance that does exactly as its name implies – removes allergens. As the allergens in the air are reduced, the quality of the air improves. Even though allergen removers aren’t a cure-all for asthma or allergies, they can help you breathe better and reduce the severity of your symptoms.

How Does an Allergen Remover Work?

To clean the surrounding air, an allergen remover must first collect the dirty air. It does so by pulling the room’s air into the appliance via a fan. Then, the air moves through one or more filtration media, which traps the pollutants. Finally, the same fan pushes the allergen-free air back into the room, and the process continuously repeats.


What Allergens Do Allergen Removers Eliminate?

An allergen remover can get rid of virtually any common airborne allergen. If you have pets, an allergen remover can reduce the hair and dander they shed. Contaminants such as pollen, cigarette smoke, and dust are no match for allergen removers.

There are even some that neutralize odors and destroy chemical substances that come from aerosol sprays, paint, and other materials. The specific allergens that an allergen remover can capture depend on the filters inside of the appliance.

What Kind of Filters Are in an Allergen Remover?

Depending on the specific model, there will be anywhere from one to three kinds of filters in an allergen remover. The most common type of filter is a HEPA, or high-efficiency particulate air, filter. This filter is designed to trap all but 0.03 percent of allergens as small as 0.3 microns, and it’s considered the heartbeat of an allergen remover.

Some allergen removers contain other filters. They may have a black filter called a carbon filter, which eliminates odors and chemicals. There may also be a pre-filter. A pre-filter has an excellent efficiency rate, but it captures large particles such as pet hair, and it prolongs the lifespan of the HEPA filter.

How Long Do the Filters Last?

The lifespan of a HEPA filter differs from that of a pre-filter. While the average HEPA filter lasts about a year, most pre-filters need to be replaced four times a year. A carbon filter is often paired with a pre-filter, so it too will need to be replaced once every three months. However, the lifespan can vary according to the frequency you run it and the number of particles in the air.

How Can I Gauge My Home’s Air Quality?

Without an air particle monitor that gives numerical readings, there is no way of knowing the health of your home’s air. There are some signs the indoor air quality is poor like the air that smells must and condensation on the windows. If your home has recently been renovated, painted or heavily cleaned, chances are the air quality is not as good as it used to be.

Will I Notice a Difference in the Air If I Use an Allergen Remover?

Within three days of using an allergen remover, you’ll notice a positive difference in the air you breathe. If the air felt heavy, it will soon be lighter. Odors that permeated the air will no longer be there. You will probably find it easier to breathe after you wake up, and you’ll notice there is less dust to clean.

Is It Safe to Run an Allergen Remover 24/7?

Absolutely! It’s not only safe to run your allergen remover nonstop but also beneficial to use it around the clock. The longer the allergen remover runs, the fewer contaminants there are in the air. Subsequently, the allergen remover’s fan won’t have to work as hard to keep the air clean, and you’ll save on energy costs in the long run.

Are Allergen Removers Quiet?

An allergen remover creates a pleasant white noise that’s relaxing. For most people, the sound produced by an allergen remover’s fan on high speed is no more bothersome than a desktop fan. On lower speeds, the fan’s sound is barely noticeable.

Allergen Remover Buyer’s Guide

Quality counts when it comes to allergen removers. From the filters it should have to the sizing, these are the factors that you should consider when buying an allergen remover.

All the Filters

You should aim for an allergen remover with every type of filter available. Besides the main, small-particle filter, it should have a pre-filter and an activated carbon filter. It’s okay if the carbon media is layered on the pre-filter just as long as the appliance has both.

A True-HEPA Filter

For the main filter, only a true-HEPA, sometimes referred to as a certified HEPA, the filter will do. If the allergen remover’s specs list a HEPA-like filter, move on. HEPA-like filters don’t have the same efficiency rate as a true-HEPA filter, meaning they leave more particles behind than the genuine version.

CADR – The Higher, the Better

Every allergen remover has different CADR ratings that vary according to the fan speed, filter measurements, and unit size. To make sure your bedroom is covered, you’ll want your allergen remover to have at least a 100 CADR in all three categories – smoke, pollen, and dust. For larger spaces like a living room, you’ll need a remover with a higher CADR.

A Great Control Panel

There are a few features that make a control panel easy to use. The labels and/or illustrations should leave no doubt as to what the buttons do. There should be indicator lights to relay critical information, and a memory function allows you to turn it on and go.

Fan/Purification Options

A quality allergen remover will have multiple fans or purification options. Larger spaces may require a higher fan speed than smaller ones, and some situations necessitate the need for more fan power than what is needed for air quality maintenance.

The Proper Size for the Room’s Square Feet

In the allergen remover’s specs, the manufacturer will usually provide a maximum number of square feet for which the remover is intended. Don’t get an undersized unit just to save a few dollars. For example, if an allergen remover’s max coverage area is 100 square feet, but your bedroom is 196 square feet, the remover won’t be able to eliminate enough allergens to be effective.
