Product review (5 stars): Does the job, no reason to buy name brand
We've been using these in our fridge for at least 3 filter changes. I replace them about the time the fridge tells me to, and I haven't had any problem or ever felt like they perform any different than the Pur version we had the first few times. Just way cheaper. I haven't done any sort of chemical testing, so I'm taking their word for it. Water tastes great, and we had pretty hard water, so it definitely does what I'm expecting it to do, thus I will keep buying them!
