When do I need to replace my air purifier filter?

The frequency of replacing your air purifier filter depends on the type of filter, the air quality in your home, and how often you use the air purifier. In general, you should replace your air purifier filter every 6 to 12 months, or as recommended by the manufacturer. Here are some signs that it's time to replace your air purifier filter:

• Reduced air flow: If you notice reduced air flow from your air purifier, it may be time to replace the filter. A dirty filter can restrict the air flow and reduce the effectiveness of the air purifier.
• Visible dirt and debris: If you notice visible dirt and debris on the filter, it's time to replace it. A dirty filter cannot effectively trap pollutants, and the pollutants can recirculate into the air.
• Foul odors: If you notice foul odors coming from the air purifier, it may be time to replace the filter. A dirty filter can harbor bacteria and other pollutants that can cause unpleasant odors.
• Increased allergy symptoms: If you or someone in your home experiences increased allergy symptoms, it may be time to replace the filter. A dirty filter cannot effectively trap allergens like pollen, dust, and pet dander.

In summary, it's important to check your air purifier filter regularly and replace it as needed to ensure your air purifier is effectively removing pollutants from your home's air.
