The best filter ever!
I was able to order this filter originally through Vine. It was the best filter we've used to date, so I went to Amazon and purchased another, just to make sure we always have one on hand. Our vacation place is on the VA coast and anyone who has lived near the water knows how skanky well water can be near the coast. This filter is truly exceptional. Our water has never tasted better. It immediately got rid of that low-tide smell typical of water in our area. We've tried paper filters, carbon filters and magnesium filters. This filter is what we had been needing. So glad I was introduced to it via Vine. I will continue to purchase more through Amazon Prime. Pricey but worth it!
