Should old filter cause odor?« Back to Previous Page

After the heavy dust storms we had last week, I noticed a slight odor when I turned on the air purifier in my living room. It’s been about two months since the last filter change, so I’m wondering if this smell is related to the old filter. Given that it's only been 2 years and I’ve never changed it myself before, should I give it a try or call in an HVAC professional?

Yes, the old filter could be causing that odor. In Dubai and throughout the UAE, we often experience dusty conditions due to sandstorms and other environmental factors. This dust can accumulate on your air purifier's filter, leading to bacterial growth and musty smells when you use the unit.

Since it has been approximately two months since your last change, it’s quite possible that the filter is now clogged with debris and moisture, which could be fostering microbial development. Dubai's climate is known for its high humidity in some areas, making this a plausible scenario.

However, before diving into changing the filter yourself, consider having an HVAC professional inspect your system. They can ensure there are no underlying issues such as leaks or mold growth that might need addressing. A professional will also clean and replace the filter correctly, helping to maintain optimal air quality in your living space.

If you decide to change it yourself, make sure to follow proper hygiene protocols. Wear gloves and a mask, and dispose of the old filter properly. For best results, use filters designed for dusty conditions as per local regulations. In Dubai, filters with high MERV ratings (Minimum Efficiency Reporting Value) are recommended to trap more particles effectively.

If after changing the filter the odor persists or if you notice any other issues like increased allergies or respiratory symptoms, it might be a good idea to call in an expert for further assessment. We recommend calling 800-MOLDS or emailing hello@saniservice.com for professional assistance and advice tailored to your specific situation.

Remember, maintaining proper air quality is crucial, especially with the varying weather conditions experienced in Dubai. Keeping on top of filter changes can significantly impact the health and comfort of your home environment.
