Air Filters

Grainger has air filters for industrial and consumer applications to clear the air. Install a permanent electrostatic air filter that needs no hookup and generates its own charge. Purchase a hospital-grade, UL Class 1 HEPA filter with 95 percent efficiency that eliminates potential air leaks. Or, for fume and odor removal, choose a carbon filter set that is disposable, eliminating the need for refilling. Grainger has air filters that help you keep indoor air clean, comfortable and safe.

Answer: 
No, they will not fit that unit, Mini-split cassette unit use a washable filter, not a disposable. Anyway 20.5" x 20.5" x 1.5" it's special order. If they are good take the 20" x 20" x 2" to your local Grainger for return or Call Grainger and mail back., When order be sure you have order the correct kind and size filter. I never see a regular filter on a cassette Mini-split unit. Do NOT try to adapter regular filter on these units, If they have the nylon washable filter!. I think they do! Look your customer manual or read it on Daikin website, you may want to call Daikin and ask. If you adapt a regular filter on is not for that unit, the unit will freezes! No cover by warranty!

I thought I remembered Grainger having an online custom filter order system but I cannot seem to find any way to order a custom size. Can I still order custom pleated filters through Grainger? If so how do I go about doing that?
