Ductless Mini Split Specialists

Mini split filters are not universal. The right part depends on your exact indoor unit model, and many units use two kinds of filters — washable mesh screens and secondary filters that need regular replacement. That is where most buying mistakes happen, and it is where we focus.

• Every listing names the indoor unit models it fits, so you can search your model number and buy with confidence.
• Annual filter bundles include every filter a given model needs for a year — no guesswork about which combination to order.
• Can't find your model? Send us your model number or a photo of the nameplate, and a real person will match the right part.
• Compatibility Guarantee: if a filter doesn't fit a model we list or recommend, we'll send the correct part or refund you in full, including return shipping. See the terms.
