I have used these filters in the past and they have definitely been removing the 'sulphur/rotten egg' stink from my well water for months. For some reason the last one I got was 1/8 inch shorter than the previous one and I had to double up the gasket on one end to keep it from rattling into the case. I hope this is a coincidence as I'm not sure. how effective it will be under pressure in the long run. I've had inconsistent packaging and quality with this product, but it handles odors well. I use it in combination with fabric softener and iron salt. It's purely for the smell and it cares with no noticeable drop in pressure. If it were a more consistent quality I would give it 5 stars.
