Should persistent cough be linked to old filters?« Back to Previous Page

After the heavy dust storm we had last week, I’ve noticed a persistent cough and wheezing whenever I’m in my son’s room. The central air filter hasn’t been changed since we moved in two years ago, and there seems to be a lot of dust bunnies under the vents. Is this normal, or should I be concerned about the health effects?

Absolutely, the persistent cough and wheezing could very well be linked to old filters. In Dubai, we see a lot of dust storms that can kick up particulates into your indoor air. Central air filters that haven't been changed for two years are like an open window for all those pesky allergens and irritants to find their way inside.

It's not uncommon to spot dust bunnies under the vents too, especially in rooms with less frequent cleaning or ventilation. These can harbor a lot of allergens, including dust mites, pet dander, and pollen that were trapped by your old filter. It’s quite possible these irritants are causing the coughing and wheezing when you're in your son's room.

In Dubai, our environment is quite arid which means we have to be extra vigilant about indoor air quality due to the frequent dust storms. The UAE doesn't have strict regulations for filter changes but it's highly recommended by health professionals like myself to change them every three months or sooner if you see a buildup of dirt and dust.

Call 800-MOLDS or email hello@saniservice.com for a professional inspection. They can assess the current state of your HVAC system and provide necessary cleanings or repairs. They can also check other areas that might be affecting air quality like ducts, humidifiers, and dehumidifiers.

Remember to keep up with regular maintenance. Regularly cleaning the area around vents, using a vacuum cleaner designed for pet hair and dander, and ensuring good ventilation can help reduce allergens in your home. If you notice any changes or worsening symptoms, it’s best to consult a medical professional as well.

Cleaning filters promptly and keeping an eye on indoor air quality is key in reducing these types of health issues. Take action now to ensure better breathing for yourself and your family!
