The Boneco W200 and W300 sell predominantly into European markets, and that changes the documentation burden more than it changes the filter. A wick shipped to a US distributor needs to fit and perform. The same wick shipped to an EU importer needs to arrive with a compliance file behind it.
| Requirement | What we supply |
|---|---|
| RoHS | Declaration of conformity covering restricted substances in the media, treatment and frame. |
| REACH | SVHC statement for the finished article, updated against the current candidate list. |
| Test reports | SGS and TÜV reports on request, arranged against your specified test scope. |
| CE marking | Technical documentation support where the finished appliance requires it. |
| EU Responsible Person | Arrangements available for importers without an established EU entity. |
Swiss-brand expectations on finish
Boneco buyers are noticeably more sensitive to visible finish quality than the market average — edge sealing, frame consistency, print registration on packaging. It is worth specifying finish tolerances explicitly at the sample stage rather than assuming the default, because a wick that performs correctly can still be rejected on appearance by a European retail channel.
The Air-O-Swiss Legacy in Part Numbering
Boneco traded as Air-O-Swiss in several markets before consolidating the brand, and that history still shows up in the parts channel. The same physical wick appears under Boneco and Air-O-Swiss numbering depending on the market and the age of the listing, and the 7135 model number appears in compatibility lists alongside the W200 and W300.
For a buyer sourcing against an old parts list, the safe approach is to work from the dimension rather than the number. The W200 and W300 wick is 270 × 150 × 52 mm; anything listed as compatible with either model, under either brand name, should measure to that. Where a legacy listing gives a different figure, it is describing a different part.
We hold this dimension on file as DL-WK-BON200 and will confirm against your sample before production, which resolves the numbering question entirely — the sample is unambiguous in a way that a superseded part number is not.
