The Dreame L40 Ultra Gen2 represents the second-generation development of one of Dreame’s premium L-series platforms, retaining the core features that made the L40 Ultra a flagship (high suction output, auto-empty dock with mop washing, retractable corner arm) and refining the details that the first generation surfaced in daily use. The performance level that makes this robot a premium investment also makes filter maintenance more consequential than it would be for a budget machine: higher suction volume means more air moves through the dust bin filter per session, and more fine particulate accumulates in the media as a result. Under daily use, the filter should be washed every four to five weeks to keep the suction at the L40 Ultra Gen2’s rated performance rather than a throttled version of it.
This 10-pack makes that schedule sustainable. Each filter is a Plus.Parts® washable antibacterial component made as a direct-fit alternative to the original Dreame L40 Ultra Gen2 dust bin filter, matched to the second-generation bin compartment geometry for straightforward installation.
The antibacterial filter medium is built to hold its performance characteristics and dimensional form through the annual cycle of washing and reinstallation. If you are not certain whether the fit applies to a specific Gen2 variant, the team can confirm directly.
