How To Choose An Air Purifier For Allergies

In the United States, dust mite allergies alone affect more than twenty million people. Furthermore, somewhere between 15% and 30% of all US citizens are allergic to dog dander. And then there are all the people with allergies to pollen, mold spores, and all the other types of pet dander out there. 

For many, the simple act of breathing indoors can trigger a cascade of unpleasant symptoms, from incessant sneezing to itchy eyes and irritated airways. So what can help reduce the number of allergens that trigger these issues? An air purifier.

Air purifiers filter out allergens and pollutants from the air, creating a cleaner and healthier indoor environment. By capturing dust mites, pet dander, pollen, mold spores, and other airborne irritants, they can reduce the number of airborne allergy triggers in your vicinity. In the article below we will explain how purifiers work, and how to choose the right one. 

Air Quality and Allergies

Allergies are the body's immune system overreacting to typically harmless substances, known as allergens, present in the environment. These allergens can vary widely and may include pollen, dust mites, pet dander, mold spores, and certain foods or medications. When individuals with allergies come into contact with these triggers, their immune system releases histamines and other chemicals, leading to a range of symptoms.

Indoor environments can harbor a myriad of allergens, making them particularly challenging for those prone to allergies. Dust mites, for example, thrive in warm, humid environments and can be found in bedding, upholstery, and carpeting. Pet dander, another common allergen, is shed by animals such as cats and dogs and can linger in the air and on surfaces for extended periods.

Furthermore, poor indoor air quality exacerbates allergy symptoms, leading to nasal congestion, sneezing, coughing, wheezing, itchy eyes, and skin irritation

How do Air Purifiers Help?

Air purifiers work by reducing airborne pollutants, allergens, and odors. They achieve this through advanced filtration systems, typically equipped with HEPA filters that efficiently capture microscopic particles like dust, pollen, and smoke. 

Furthermore, air purifiers feature activated carbon filters, which excel at trapping odors from cooking, pets, smoke, and other sources. Some models are even equipped with specialized filters designed to diminish volatile organic compounds (VOCs) and other harmful chemicals, contributing to better respiratory health and overall well-being.

How to Choose the Best Air Purifier for your Allergies

When it comes to choosing the best air purifier for allergies, there are several important factors to consider. If price is a concern, we offer options such as Paypal Credit, Affirm, and Shop Pay to pay in installments or over time. You may also be able to use your FSA or HSA to contribute to your air purifier purchase.

Below are some key considerations to keep in mind:

Look for HEPA filters

Air purifiers employ various filtration technologies to reduce airborne pollutants and allergens. Look for purifiers with HEPA filters, which are constructed from a dense network of fibers arranged in a random pattern, allowing them to capture particles as small as 0.3 microns in size with a high degree of efficiency. 

Additionally, activated carbon filters are effective in trapping odors and absorbing harmful chemicals. 

Room Size and Coverage Area

Consider the size of the room where you plan to use the air purifier. Choose a purifier with adequate coverage to ensure optimal reduction of allergen triggers. The best way to be 100% certain is to pay attention to the manufacturer's recommendations for room size.

CADR (Clean Air Delivery Rate)

CADR measures the efficiency of an air purifier in reducing airborne particles in the air. Look for purifiers with higher CADR ratings, indicating a faster and more efficient reduction of allergy triggers. Keep in mind that CADR ratings may vary depending on the type of pollutant, such as dust, pollen, or smoke, but it’s a reliable indicator of the purifier's performance.

However, as a rule of thumb, the CADR rating of your air cleaner should be two-thirds of the square footage of the room it will be placed in.

Noise Level

Consider the noise level of the air purifier, especially if you plan to use it in bedrooms or other quiet areas of your home. Opt for purifiers with quiet operation modes or adjustable fan speeds to minimize noise while still effectively reducing allergy triggers in the air. 

Energy Efficiency

Evaluate the energy consumption of different purifier models to minimize operating costs. Energy-efficient purifiers consume less electricity, resulting in lower utility bills over time. Look for purifiers with Energy Star certification or other energy-saving features.

Additional Features

Consider any additional features or functionalities offered by the air purifier. This may include smart capabilities, such as Wi-Fi connectivity and smartphone control, as well as built-in air quality sensors, programmable timers, and filter replacement indicators.


Investing in the right air purifier can make a significant difference in managing allergy symptoms and improving overall indoor air quality. By considering factors such as filtration technology, room size, budget, and specific allergy needs, you can choose an air purifier that effectively reduces allergens and provides much-needed relief.
