When we think of allergies, we often imagine seasonal spring allergies, but it is not just the outdoors that hides threats. The air we breathe indoors can also significantly impact our health. Poor indoor quality allows allergens and pollutants to build up, leading to respiratory issues and skin irritations. Common indoor allergens can include dust mites, pet dander, mould spores, and pollen. Without proper measures, these can accumulate in our homes and offices, triggering or even worsening our allergies. However, learning how these particulates contribute to air pollution in enclosed spaces can help us take the right measures to maintain a healthier living environment, reduce indoor allergens, and manage our allergy symptoms. In this article, we highlight key indoor air quality factors that aggravate allergies and share practical solutions for relief. How Indoor Allergens Can Worsen Our Allergies Increased Exposure to the Allergens Indoor environments can trap and expose us to particulate matter like dust, mould, and pet dander, which can trigger allergy symptoms. Without proper ventilation, allergens will continue to settle on furniture and linger in the environment. Over time, prolonged exposure can cause severe reactions in people with respiratory and dermatological conditions. Imbalances in Humidity Levels Humidity is another factor to consider. If the air is too dry, it can irritate the nasal passages and throat, increasing susceptibility to allergens. Too much humidity, however, creates the perfect environment for mould and dust mites to thrive—both common allergy triggers. Chemical Irritants Volatile organic compounds (VOCs) are common pollutants found in most indoor spaces, especially in paints, cleaning products, air fresheners, and some textiles. If you have been exposed to VOCs for an extended period, you may experience throat irritation, headaches, dizziness, and respiratory issues. If you're prone to allergies, these irritants can worsen your symptoms. Poor Ventilation If you do not maintain adequate airflow in your home or office spaces, the indoor air can become stagnant and trap allergens inside. As a result, dust, mould, and VOCs accumulate and circulate more easily in the air you breathe. This leads to a higher concentration of airborne irritants, and further worsens indoor air quality and existing allergies. How to Maintain Better Indoor Quality & Relieve Allergies Implement Air Purifiers In spaces where ventilation is limited, indoor allergy air purifier solutions and HVAC systems (Heat, Ventilation, and Air Conditioning) with filters can improve air circulation and reduce allergens. If you are thinking of installing a HVAC system, it’s recommended that you consider Mechanical Ventilation with Heat Recovery (MHVR) systems . They can provide a balanced extract and supply of air, recovering up to 95% of the heat that in any other condition would be lost. Considering the amount of resources that go into heating a big space, this type of system is something to keep in mind. Hence, installing this system is not only good for the economy of your business, but also beneficial for the occupants. These systems, especially those equipped with HEPA filters (high-efficiency particulate arresting filters), work by consistently drawing in air and filtering out contaminants. In this way, they trap airborne particles like dust, pollen, and pet dander, preventing them from circulating through your space. As a result, air quality is greatly enhanced, providing a cleaner and more comfortable environment for your customers and employees. Such systems can be invaluable for businesses aiming to improve employee well-being. They reduce exposure to irritants that can cause discomfort or trigger allergies, boost productivity, and create an overall healthier workspace. We advise placing air purifiers in high-traffic areas such as offices, meeting rooms, and break rooms, where allergens circulate the most. Control The Humidity Levels One way to help balance the humidity levels indoors is to use a dehumidifier when humidity is high, typically in areas like basements and bathrooms. When the air becomes too dry, especially in colder months, a humidifier can help add moisture to the air. The optimal level you should strive for is 30-50%. This range prevents mould growth, dust mites, and other allergens from accumulating, greatly improving indoor air quality. To help you understand humidity levels, our intelligent monitoring system, InBiot , can provide insights into indoor air quality and can help you detect harmful pollutants before they become a concern. If you're unsure about your space's humidity levels, schedule an indoor air quality assessment with our experts, and we will guide you to the right solution. Clean Your Space Regularly It’s as simple as that. Cleaning your indoor space regularly is still one of the most effective ways to minimise home allergens. Opt for vacuums with HEPA filters to remove all dust, pet hair, and pollen from carpets and upholstery. Dura Vacuums are also an excellent choice for maintaining healthy air quality and controlling dust buildup in your indoor spaces. They are designed to withstand the demanding conditions of industrial environments and can effectively handle both wet and dry particles. Additionally, regularly dusting surfaces and washing bedding, curtains, and rugs in hot water will help reduce allergens in the air. Another good idea is to make sure you declutter your place often, as this can also reduce the risk of dust buildup and potential hiding spots for allergens. Ventilate Often Another simple measure that never fails is to make sure you ventilate your indoors as often as possible. Open your windows whenever the weather permits it, and use exhaust fans in the kitchens and bathrooms. For those with allergies, combining this with high-quality HVAC filters and cleaning air ducts to reduce airborne irritants is best. Opt for Hypoallergenic Materials There are many materials in our closed spaces that can contribute to indoor air pollution. Whenever you can, choose more natural or non-toxic cleaning products and materials, preferably with low VOC, and make sure to ventilate when using chemical-based products. You can also take things further by choosing wool and cotton bedding,hardwood floors instead of carpets. It is more difficult for irritants to accumulate on these materials and surfaces. Eliminate Mould & Mildew One of the major triggers for allergies and other respiratory issues, mould spores should be cleaned as often as possible. You can regularly inspect damp areas like bathrooms, kitchens and basements with the help of professionals to prevent mould growth. To further contribute to healthier indoor air, use mould-resistant paint and fix leaks as soon as possible. Improving Indoor Air Quality The key to keeping allergens at bay is maintaining optimum air quality indoors. Simple changes in habits like regularly cleaning our spaces and ventilating whenever we can can significantly improve air quality. Devices such as purifiers and HVAC systems can be another proactive approach to supporting long-term health.
