Zerowater Replacement Filters for Pitchers (4 Pack)

If you want the purest water this is it. Using better water for your source will increase you filter life. Or the dirtier your input water the shorter life before changing rhe filter. You can use the TDS tester to check water so u rces to know what you are using and that the filter is still withing or needs replacing. Great product. You may nwed to check the filter seal to make sure no unfiltered water leaks into the pitcher.. Just retighten. Once that is sealed no adjustment needed until replacing the fulter.

These are great and make the best tasting water. Depending on your water quality depends on how long they last. I use the filtered water for almost everything I cook and drink (as well as for my pets) daily and change the filter about every two or two and a half months. If you're a water snob like myself, you can't get any better than this.

Filters my water wonderfully. Works for quite a long time. Wouldn’t drink my water without using filtration!

Great quality filters for a good price! No problems at all, these fit perfectly in the pitcher and no leaking after screwing in the replacement. Always be sure to run through a first run and toss it before filtering through the water you drink.

Generally a very good product. water taste is very much improved. Have had one filter that just would not allow water through at all. I shook it up a couple times but it was just to dense. other than that, this works very well

the best filter system that we have ever had.

I live in an area with high levels of chemicals and minerals in the city water always tastes funny. now i love drinking my water. but it does make the filter not last as long because of how bad our water is. MY READING WERE 450 AND UP DEPENDING ON THE DAY FROM THE TAP. Now 000 all day every day unless the filter is starting to go.

This is a regular purchase for me for several years. I test the filtered water afterwards, and usually find "000" ppm, same as distilled water. The filters usually last me about 4 weeks, but when quality of tap water is very poor, a filter may last only a few weeks. When throughput slows down too much, shaking up the filter has resolved the problem for me.I recommend adding 4 drops per quart of (Concentrace or equivalent) mineral drops after filtering, to replace magnesium and other minerals in drinking water to avoid muscle cramps.
