    Why can't I just buy it from your warehouse like I use to?

    I used to be able to buy the filter directly from your warehouse. It was convenient. No shipping charges. I would like to do that again. I live 2 miles from your place of business.

    Hi Robert, thanks for being a valuable customer and for leaving a 5-star review.

    About you picking up you filter kit at our warehouse; there are a few reasons we had to stop this practice. I know it seems crazy but it’s the world we live and work in. Please note there is no charge for shipping to you.

    I’ve never gotten one back, I’ve never had a complaint

    We actually have quite a few customers that do like your single cartridge system that is the sediment and the water softener. I would say that I’ve never had one come back before, I’ve never gotten one back, I’ve never had a complaint.

    When they go to install one I say now if you have a salt system you probably won’t be happy just because the waters not going to be that slimy feeling, if your used to one thing its not going to be that way. Sometimes people get it sometimes they don’t. I mean we definitely have a lot of plumbers here in town who really like the system but it would be nice if more people knew about it.

    I don’t hear much feedback from customers and a lot of time I say No News is Good News because when I hear about it it usually means something is wrong.

    Silica problems solved

    Gabe, I have checked at least 6 of the ones I have installed and they all tested the same. So far no one has complained. The applications range from 51ppm to 79ppm silica.

    The performance of these filters far exceed the previous salt filters I once used

    “Great assistance from the company and very glad to see these products available. It seems expensive (and it is) but the fact that we don’t have to buy and hassle with salt and we don’t have to change them every couple months justifies the cost. The performance of these filters far exceed the previous salt filters I once used. We had this filtering system going on 2 years now and not one problem. A little piece mind goes a long way when you are a new homeowner.”
