- New products may emit an odor when first used, that is normal. When turning on Heat Mode for the first time there may be a faint smell. Run the device and ventilate the room to air out the air purifier and its filter to reduce the odor faster.
- All materials have their own smell, including filter materials. The filter is enclosed by a plastic bag and a cardboard box, and the smell from the product is accumulated inside. The smell from filter media is harmless.
- If the device has been stored for some time and not used, dust may collect on the heater causing a smell when initially turned on. This should dissipate within 15 minutes.
- When the filter is full and gets saturated with debris it can start to release a smell, and we recommend replacing it.
- The average expected lifetime of the filter is stated for each Blueair product. However, the expected filter lifetime can be highly dependent on the environment the air purifier is in which could require more frequent replacement.
