Quick verdict
Buy the genuine filter if you own a 539 or 539S; at $29.99 it is already cheap, so third-party copies save only a few dollars and add fit and carbon-quality risk. Just make sure the listing says 539/539S (DR-HAP009/DR-HAP009S), not 539AS or 530S.
Ideal for
- Dreo 539S (DR-HAP009S) and 539 (DR-HAP009) owners
- Owners who want a color-matched filter (white or black)
- Anyone replacing on Dreo's 6–8 month schedule
Not ideal for
- Dreo 539AS or 530S owners (they need the 3-in-1 HEPA Pro filter)
- Heavy odor or smoke use, where the thin carbon layer wears out fast
The full picture
This is Dreo's own cartridge for the Air Purifier 539 (DR-HAP009) and 539S (DR-HAP009S). It combines a pre-filter, a HEPA layer Dreo rates at 99.97% of 0.3-micron particles and an activated-carbon layer in one cylinder, and it swaps without tools. Dreo sells it in white and black to match the purifier's housing, lists it at $29.99 and rates it for 6 to 8 months. The pet-focused 539AS and the 530S look similar but use a different HEPA Pro filter.

Frequently asked questions
Do the Dreo 539 and 539S use the same filter?
Yes. Dreo sells one 3-in-1 HEPA filter labeled for the 539/539S (DR-HAP009/DR-HAP009S). The Wi-Fi is the only meaningful difference between those two purifiers.
Does the 539S filter fit the Dreo 539AS?
No. The 539AS and 530S use the 3-in-1 HEPA Pro filter, which Dreo lists at $38.99 and which works with the 539AS's replaceable pet-hair pre-filter. Check the model code on your unit's rating label before ordering.
How often should I replace the Dreo 539S filter?
Dreo rates it for 6 to 8 months. Lean toward 6 months with pets, smoke or heavy cooking. At $29.99, that works out to roughly $45 to $60 a year.
Does the filter color matter?
Only for looks. Dreo sells the 539/539S filter in white and black to match the purifier's housing, and both are listed for the same models.
