    Excellent product to filter unwanted particles from our tap water. Have been very pleased with this product all the years we have used it. Will continue purchasing it.

    Excellent filter. At some point in the last 6 months, my well began picking up mud. The filter showed it, but there was none in the water coming out of the tap. Great product!

    The filters last a whole year without any problems and when replaced on a yearly basis there is never a problem. The diverter valve does not last as long I would like. We have had to buy too many of these assemblies.

    Better than ever

    Posted by Scott Smith on Jul 7th 2023

    I purchased my MPC250 back when they were being sold through an MLM, about 30 years ago. Over the years improvements were made to the replacement filters, improvements that were not really discernible by taste, only in the testing. As municipal water supplies struggle to maintain themselves, they can barely keep up with all the additional chemicals now being found in their source water. Through it all, Multi-Pure has consistently stayed ahead of the game. Guests simply cannot believe that the water I serve them is not bottled, and they do ask. Some have sought to purchase even larger units from Multi-Pure. I have never met anyone who has better water than I do with this unit, even those with r/o which to me tastes flat.
