Could AC Filter Issues Cause Stale Air and Throat Irritation?« Back to Previous Page

Since we moved into our new apartment a year ago, the air feels a bit stale, especially after the AC has been running all day. The other day, my daughter complained of a scratchy throat, which had me wondering if it could be due to poor air quality from the filter not being replaced. I’ve checked the filters in the kitchen and bedroom, but they seem fine. Could there be an issue with the main AC unit’s filter, or is this just a coincidence?

Could AC Filter Issues Cause Stale Air and Throat Irritation?

Yep, it's very likely that a clogged or old air filter could be the culprit behind those issues you're experiencing. In Dubai and other parts of the UAE, our climate is quite harsh, with high temperatures and humidity during summer. This makes maintaining your HVAC system especially important to ensure good indoor air quality.

Air filters in AC units are designed to catch dust, pollen, and other particles as they circulate through the system. Over time, these filters can get clogged, reducing airflow and potentially leading to stale air conditions. The reduced air flow could also contribute to a feeling of discomfort, especially if you're using your AC for extended periods.

Regarding that scratchy throat - this is one common symptom linked with poor indoor air quality caused by dirty filters or other factors like mold growth in the system. Mold can thrive in humid environments and might not always be visible, but its spores can irritate the respiratory system, leading to discomfort or allergic reactions.

When you checked your kitchen and bedroom filters, they seemed okay - but it's important to remember that many AC systems have a main filter which is usually located near the air handler. This could potentially be where the problem lies if your symptoms are linked to use of the entire unit.

For accurate assessment, I'd recommend scheduling an inspection with a professional HVAC service provider. They can check your filters and overall system efficiency, making sure everything's running smoothly for both comfort and health reasons. In Dubai, you might consider calling 800-MOLDS or emailing hello@saniservice.com to book an inspection.

Until then, you could take some basic steps like changing the filter yourself if it hasn't been done in a while - typically, filters should be replaced every 3-6 months depending on usage and environment. If the filter is still clean but your symptoms persist, consider checking for any signs of mold or water damage which can indicate other issues that might need attention.

Remember to keep windows closed during extreme heat and humidity outside to help maintain better indoor air quality!
