Vornado MD1-0034 Replacement Humidifier Wick (Pack of 2) , White

Can these new "thinner" filters be "doubled up"? That is, is there room to use two (2) new thinner ones in lieu of the original thicker one?

Will it fit Vornado model HU1-0048-43?

Does this type of Vornado wick filer come in a 4 or 6-pack? There are some generics inthe market, but I prefer the original type if it is affordable.
