Product review (5 stars): Great value for quality product
These filters are amazing for the price. Although the OEM filters do last longer due to the price difference these are much more affordable option. The instructions outline replacing every 6 months, but based on my use of these filters I would recommend changing every 3 to 4 months as they can begin to develop a taste. Also, after installing you'll want to fill up one or two pitchers worth of water to clear out the filter and to get out any air pockets in the lines that could cause sputtering.
