Quick answer

Choose the 539 filter if you own a DREO 539 or 539S (white) purifier; choose the 338 filter if you own a DREO 338 or 338S (black or white). They are not interchangeable, so matching your exact purifier model is essential.

Why model compatibility matters

Each DREO air purifier is designed to work with a specific 3-in-1 HEPA filter. Using the wrong filter can affect airflow, filtration efficiency, and fit. The 539 filter is built for the DR-HAP009/DR-HAP009S series, while the 338 filter is for the DR-HAP008/DR-HAP008S series. Always check your purifier's model number before ordering.

Price and value differences

The 539 filter is priced at $22.49 (compared to $29.99), while the 338 filter costs $17.54 (compared to $26.99). Both offer savings over their comparison prices, but the 338 is the more budget-friendly option if it fits your purifier. Keep in mind that an $8 shipping fee applies per accessory type in your order.

Decision rules for choosing your replacement filter

  • Check your purifier model number: Look on the back or bottom of your DREO air purifier for the model number (e.g., DR-HAP009 or DR-HAP008). This is the only way to confirm compatibility.
  • Match the filter to the model: If your model is DR-HAP009 or DR-HAP009S (white), choose the 539 filter. If it's DR-HAP008 or DR-HAP008S (black or white), choose the 338 filter. The 539 and 338 filters are not interchangeable.
  • Consider the cost per filter: The 338 filter costs $17.54, while the 539 filter costs $22.49. Both include an $8 shipping fee per accessory type. If both fit your purifier (they don't), the 338 is cheaper — but compatibility comes first. Always prioritize fit over price.
