Hi everyone,
I recently purchased a Dyson BP04 air purifier, but I’ve been dealing with a persistent odor coming from the K-Carbon filter since the first use.
I originally kept my first BP04 unit running continuously for over a month, hoping the smell would fade, but it didn’t. Dyson eventually replaced the unit with a brand-new one, but the exact same issue happened with the replacement.
What I’ve Noticed:
• The odor started immediately and hasn’t disappeared, even after weeks of continuous use.
• It doesn’t seem like the usual “new filter” smell—it lingers much longer than expected.
• Both my original and replacement units had the same issue, making me suspect a possible batch-related defect in the K-Carbon filters.
What I’ve Tried:
✔ Running the purifier on max speed for extended periods
✔ Removing the filter and airing it out separately
✔ Ensuring the room isn’t humid to avoid moisture absorption
✔ Checking for any external odor sources being trapped in the filter
Since I’ve had this issue with two different machines, I’ve contacted Dyson Support to ask whether my filters might be from the same production batch and if this problem has been reported by other users.
Device Serial Numbers for Dyson Support:
• First BP04 Serial Number: T7X-XD-THAO310A
• Second BP04 Serial Number: T7X-XD-TNA0438A
I’d appreciate it if Dyson Support or other users could check if these two machines are from the same production batch or if there have been similar reports from other customers.
