🌿 Fresh Relief: Can AC Help Reduce Allergies? | Homeowner's Guide

With each allergy season seeming to be more potent and longer than the last, many people are looking for ways to reduce allergen levels and protect their indoor air. In addition to their cooling abilities, air conditioning (AC) systems may also be key in reducing indoor allergens. But how effective are they? This article explores the relationship between air conditioning and allergies and how homeowners can use it to their advantage.

The Role of Air Conditioning in Allergen Reduction

AC can be a great friend to allergies, especially if those allergies are affected by indoor air quality and humidity. There are some specific ways that ACs can affect allergies, and being aware of them can help you make choices about your air conditioning system to support your health.

Filtering Out the Troublesome Particles

Modern air-conditioning units are designed with filters to catch dust, pollen, pet dander and other allergens that can be in the air. Of note here is the High Efficiency Particulate Air (HEPA) filter, which is very efficient at trapping particles that release allergens such as sneezing and coughing. A person who has allergies should consider upgrading to a new system with a HEPA filter or one that can be retrofitted to accommodate HEPA filters.

Humidity Control: A Double-Edged Sword

AC units also help to regulate humidity, which can have a large impact on allergens. Mould and dust mites, common allergens, thrive in humid surroundings, so indoor humidity should be kept between 40 and 60 per cent with air conditioning. If it gets too dry, the air can irritate mucous membranes, so it is important to find a balance.

Regular Maintenance is Key

Proper care is critical because an AC will work only if it has not built up a collection of allergens. Filters should be cleaned or replaced according to the manufacturers’ instructions. It is usually recommended once every three months, but can be more frequently, especially during peak-use periods. If you don’t do this, the AC can quickly turn into a source of allergens, spreading dust and mould around the house.

Actionable Insights for Homeowners

To leverage air conditioning as a tool against allergies, consider the following tips: Add HEPA Filters: You need to upgrade your central air system with a HEPA filter to capture the allergens. Keep humidity in check: Use a hygrometer to track indoor humidity at the ideal range of 40-60 per cent. Regular Servicing: Have your AC serviced annually by a professional. Use and clean your filters as specified by the manufacturer. Ventilation: Combine air-conditioning with regular ventilation (opening door and windows) to introduce fresh air and dilute indoor allergens.

In Summary

With proper use and maintenance, air conditioning can retain fewer allergens indoors, and will also help allergy sufferers. Getting your air right, managing humidity and having your system properly maintained can make your home more comfortable and healthier.
