If you have allergies, your health depends on choosing an effective air purifier. To help you make this important decision, we’ve compiled a descriptive list of the features you can get in an air purifier.

To learn more on the benefits of air purifier we recommend reading out article on why air purifiers are worth every penny.

Air Purifier Size

When we mention size, we don’t mean the air purifier’s dimensions although you should take its width and height into consideration for the purpose of placement. Instead, we mean the largest room in which the purifier can adequately function. Almost all manufacturers mark their purifiers with its intended room size. You can find this information in the product description or user’s manual.

Air Purifier CADR

As you know, CADR stands for clean air delivery rate, which is determined by the swiftness of the purifier’s airflow and the efficiency of the purifier’s particle filtration. For smoke and pollen, the maximum rate is 450.

For dust, the highest number is 400. To get the excellent whole-room purification, look for a purifier with a CADR of at least 100 in all three categories.

Air Purifier Filtration

In regard to how many filters are the best number of filters, you are always better off with as many levels of filtration as you can get. At a minimum, you need at least three, and one of the three must be a HEPA filter. Other common filters to find in an air purifier include a pre-filter and an activated carbon filter. Some purifiers also have a negative ion generator or a UV-C light.

Air Purifier Fan

Although it’s controlled by the motor, the fan is the mechanism that gets the room’s air circulating. You want a purifier with a multi-speed fan, so you can customize the purification intensity according to the volume of particles in the air. This feature comes on most air purifiers with the number of fan speeds usually ranging from three to five.

Air Purifier Sound

Since the fan is the purifier’s main moving component, it’s responsible for the majority of the noise output of the air purifier. Like many people, you don’t want an appliance that drowns out your Netflix binging or phone conversation. Often, the manufacturer will list the model’s decibel range. However, another indication that the air purifier is quiet is if it has a brushless motor.

Air Purifier Settings

Convenience should also be a consideration. Some air purifiers are equipped with a timer, so you can set it to run for a specific length of time. There are also models with various operating modes such as an auto mode that allows the purifier to change the settings based on the air quality. Others may have a quiet-fan mode or an energy-saving mode.

Air Purifier Air Quality Indicator

It’s helpful to know what the air quality is inside of your home, so you can adjust the purifier’s settings when necessary. The indicator may be a color changer that turns different hues according to the whether the air quality is bad or good. Another indicator style is the numerical variety, which displays the air quality level in numbers, not colors.

Air Purifier Controls

Others also come with a remote for across-the-room control. Then, there are smart air purifier that let you access their functions via smartphones and virtual home assistants.

FAQs

What Are Common Household Allergens?

Every household in America contains some allergens. Dust mites are the most common indoor allergen.

These microscopic organisms thrive in areas that are warm and humid, preferring to stay in carpet, fabric, and upholstery. However, when you vacuum, make your bed or walk on your carpet, the dust mites are flung into the air, often triggering allergy symptoms in those who are allergic to dust mites.

Mold is another commonplace problem. Usually found in bathrooms and kitchens, mold produces airborne spores, which you can easily inhale. You can also bring tree and flower pollen inside your house from the clothes and shoes you wear outdoors.

Even your pets can track pollen. On the subject of pets, their fur and dander can also trigger allergies. Don’t forget about smoke. Whether from cooking, fireplaces or cigarettes, smoke has serious negative effects on your health.

What Is Particulate Matter Pollution?

Particulate matter consists of extremely small particles that are combined with liquid airborne droplets. These particles vary in size. Some are big enough to be visible with just your eyes while others can only be seen through a microscope.

Over time, exposure to particulate matter pollution can impact your respiratory and cardiovascular systems. However, it’s the particles that are smaller than 10 microns that are the biggest threat, which are the ones you can’t see.

Best Air Purifiers for Allergies

What Are Volatile Organic Compounds?

Volatile organic compounds, or VOCs, are gaseous chemicals that are released from all types of items from liquids to solids.

The complete list of products that emit VOCs is extremely long; however, some common culprits include adhesives, air fresheners, burning wood and fuel, candles, carpeting, cleaning solutions, perfume, pressed wood and wallpaper.

According to the Environmental Protection Agency, indoor VOCs levels are typically 10 times higher than outdoor levels. Short of living in a vacuumed bubble, you can’t escape VOCs. The key to managing them is reducing the volume of volatile organic compounds in your home, keeping that volume under 500 nanograms per liter.

How Can I Keep the Air in My Home Clean?

From floor care to pet care, there are many steps you can take to reduce the number of allergens in your home. First, mop and vacuum on a regular basis, and make changing your linens a weekly habit.

When you cook or take a shower, be sure to turn on the exhaust fan to reduce odors and lower the relative humidity, aiming for a humidity that ranges from 30 to 50 percent.
Another preventative measure is to take off your shoes as soon as you come home. Also, don’t let smokers light up inside of your house, and be vigilant about changing your HVAC filters every month. If you own pets, groom them once per week – bathing, brushing, the whole nine yards. Finally, an efficient air purifier can help maintain a healthy indoor air quality.

How Do Air Purifiers Work?

When used as part of a comprehensive allergy-reduction plan, an air purifier does a fantastic job of cleaning the air around you. Within an air purifier, there is a fan. As this fan spins, the air in the room is pulled into the purifier’s inlets.

Once inside the purifier, the air is pushed through a filtration system that traps pollutants.
Some air purifiers even have germ-killing mechanisms like a negative ionizer or an ultraviolet light to enhance the purifier’s efficiency. Once the air is clean, it’s pushed out of the outlet grille where it recirculates through the room.

What’s the Hype Over HEPA Filters?

Air filters come in all sizes and efficiency levels. If you want to knock out those microscopic particles that the EPA has found to be the most harmful, you need an air purifier with a high-efficiency particulate air, or HEPA, filter.

Generally, HEPA filters can trap more airborne particles and smaller particles than a standard air filter. At a minimum, a HEPA filter is able to capture 99.97 percent of particles that are as tiny as 0.3 microns.

What Is a Negative Ionizer?

Some air purifiers contain a negative ionizer. This mechanism creates negatively charged ions, which the purifier pushes into the air. Then, the ions cling to allergens, causing most of them to stick to walls, tables, and other surfaces instead of floating in the air, so you can’t inhale them. However, some of the particles make their way to the purifier where they are caught by the filter.

Why Do Some Air Purifiers Have an Ultraviolet Light Bulb?

UV-C is considered a short wavelength of ultraviolet light. This kind of ultraviolet light is capable of rendering bacteria, fungi, and viruses ineffective in seconds by destroying them at a molecular level.

Once germs and allergens are captured by an air purifier’s filter, the internal UV-C light beams on the filter to kill these particles. Even though you can’t rely on UV-C light alone for cleaning the air, it is a helpful extra to have in an air purifier.

best air purifiers

What Does CADR Mean?

In an effort to guide consumers who are shopping for an air purifier, the Association of Home Appliance Manufacturers applies three numbers to each model submitted voluntarily by manufacturers. Each of these numbers is called a clean air delivery rate, and it not only tells you how quickly the purifier circulates air but also how efficiently it cleans the air.

There is one number that applies to the air purifier’s ability to trap dust particles. The other two numbers relate to smoke particles and pollen particles. Generally, the higher the number, the better the purifier is at cleaning the air.
