Just cut down a furnace filter to fit inside. I’ve been doing that for years with a few Sharp units I can’t get filters for any more (discontinued) and some newer Levoits. If you leave them running all the time on low they are more effective than running them part of the day with the “official” filters.
- neilv 6y agoGood idea -- that would work for my larger Levoit unit, which takes a pair of flat rectangular filters, though not for the smaller cylindrical unit. For now, I'm going to try to keep buying the Levoit filters, since I think they have more "layers" than the furnace filters, and I don't have a good sense of what all I should to be filtering in this location. But it's good to have a backup plan.
