Product review (3 stars): BestAir EF1 Kenmore 14906 / Emerson MAF1 Replacement Wick Filter
They are cheaper than Sears brand but they don't last as long as Sears brand so it sort of evens out. I've bought several of these BestAir filters for my Kenmore humidifier. I think I will try to find the Sears brand online for my next order. I literally swap these out every 3 weeks or so because they stop drawing water up. I also don't use the mildew stopping additive because I read somewhere it shortens the life of the filters.
