How much are Farberware charcoal filters?

As of 2015, Farberware digital coffee maker coffee filters cost around $5 for a pack of six at Wal-Mart. A variety of off-brand and generic charcoal coffee filters are available online for similar prices.

While charcoal filters do remove mineral and chemical contaminants from water, they do little to filter biological contaminants, according to Fox News Magazine. Charcoal filters enhance the flavor of coffee by reducing the amount of chlorine and sediment in the water. Replacing the charcoal filter in a coffee maker does not make it more sanitary. Sanitize coffee makers with a mixture of vinegar and water at least once a month.
