Fighting Allergies with Air Conditioner Filters

As the weather warms up and we spend more time indoors, it’s important to consider the quality of the air we breathe. Allergies are a common concern, affecting millions of people each year. If you want to improve your indoor air quality and reduce allergy symptoms, air conditioner filters are a simple yet effective solution. Let’s explore how they work and why they are a must-have for your home.

What Are Allergies?

Allergies are an overreaction of the immune system to substances that are typically not harmful. Common allergens include pollen, dust mites, pet dander, and certain foods. When these allergens enter the body, the immune system mistakes them for a threat and produces antibodies to fight them off, leading to allergic symptoms. These symptoms can range from mild, such as sneezing and itching, to severe, like anaphylaxis.

Understanding what allergies are and identifying specific triggers is crucial in managing and preventing allergic reactions. It allows individuals to take necessary precautions, such as using air conditioner filters to reduce indoor allergens, and seeking appropriate medical treatment.

What Causes Allergies?

Allergies are typically caused by the body’s immune system reacting to substances such as pollen, pet dander, dust mites, or certain foods. When these allergens are encountered, the immune system overreacts, producing antibodies that release chemicals such as histamine, leading to allergy symptoms. Understanding what causes allergies can help individuals take proactive measures to minimize exposure to these triggers and manage their symptoms effectively.

Fact: Did you know that more than 50 million people in the United States experience various types of allergies each year, making allergies the 6th leading cause of chronic illness in the country?

From fibreglass to HEPA filters, each type offers its own benefits and we will explore how they differ from one another.

1. Fibreglass Filters

Fibreglass filters are the most basic and economical option for air conditioner filtration. They consist of layered fiberglass fibres, designed to capture larger particles like dust and dirt. These filters are suitable for protecting the HVAC system from debris buildup. However, they are less effective at trapping smaller allergens like pollen and pet dander. Consider upgrading to higher efficiency filters like pleated, electrostatic, or HEPA filters for better allergen removal.

2. Pleated Filters

High Efficiency: Pleated filters offer a higher efficiency in capturing small particles due to their extended surface area.

Improved Air Quality: These filters effectively trap allergens such as pollen, pet dander, and dust mites, enhancing indoor air quality.

Longevity: With proper maintenance, pleated filters have a longer lifespan compared to standard fiberglass filters.

Compatibility: They are compatible with various HVAC systems, providing flexibility for users.

Pleated air filters were first introduced in the 1940s as an innovative solution to enhance air quality in homes and commercial spaces. Their design and efficiency have since evolved, making them a popular choice for allergy relief and overall air purification.

3. Electrostatic Filters

Electrostatic filters use self-charging fibres to attract and trap small particles, including allergens like pollen, pet dander, and dust mites. These filters are reusable and can be washed, making them cost-effective and environmentally friendly. Regular cleaning is essential to maintain their efficiency in capturing allergens. It’s crucial to follow the manufacturer’s instructions for cleaning and replacing electrostatic filters to ensure optimal allergy relief.

When considering electrostatic filters, prioritise proper maintenance and adhere to the recommended cleaning schedule for effective allergen removal.

4. HEPA Filters

HEPA filters are highly efficient at capturing airborne particles, making them an excellent choice for allergy relief. Here are steps to consider when using HEPA filters:

  1. Identify Filter Size: Ensure the HEPA filter fits your air conditioning system correctly to maximise its effectiveness.
  2. Check MERV Rating: Look for a Minimum Efficiency Reporting Value (MERV) of 17 to 20 for true HEPA performance.
  3. Replace Regularly: Follow manufacturer recommendations for filter replacement, usually every 6 to 12 months, to maintain optimal filtration.
  4. Consider Filter Upkeep: Keep the surrounding area clean to prevent particles from accumulating and decreasing filter efficiency.
