I bought these to replace expensive OEM Brita filters thinking I got a bargain. It turns out you get what you pay for. They work, but aren't good enough at stopping air, meaning you'll end up sucking in air when trying to get water (probably 50% air). Although I'm using the manufacturer's installation instructions, there may be another trick to make it work better. Haven't found one yet and will buy OEM Brita filters next time if I can't find a solution.
