Q: How many “clean” baths can this unit provide?

A: This filter can provide you with any number of baths because its lifespan is measured in gallons. But if you struggle to know when the 1 million gallon is then just consider the 10 year period as a good rule of thumb.

Best Sediment Filter For Well Water?

Well water has specific issues that can only be treated with specialist filters.

This is because well water can suffer from contaminants that are not present in the average home water supply. For instance, water companies will typically be able to remove heavy metals like lead before it reaches your home.Mr Water Geek Thinking Also the average home does not have to worry about things like arsenic contamination.

However, a well water owner may have to take all of these into consideration.

By far the most effective way to do this is to get a powerful whole house filter that can eliminate everything at source before it even reaches your home.

Optimh2o Reverse Osmosis + Claryum

There is almost no point in doing a water test unless you’re going to commit to doing it regularly and buying new filters to deal with new issues.Because the nature of well water is that it’s a lot more organic and therefore likely to change in composition. While, on the other hand, water from the water company or municipal supplied water are more likely to be “standardized” and “homogenized” due to government regulations.

  1. Hello! I need to buy a whole house water filter for the water coming in from my well. I have both iron and maganese, it’s not too bad, but I do need to filter it. You speak about lead being filtered but not the other two. Does the AquaSana also filter the iron and manganese? I want to filter for those minerals, plus sediment, and odor.
    Thank you! Trisha

    • Hi Trisha

      Yes, the OptimH2O filter is certified to filter lead as well as all the other harmful bacteria listed in the article. It will deal with all sediments and odors especially if you get the UV filter upgrade.

      It is not certified to remove iron and manganese so they can’t make this claim. However, this is one of the most powerful filters that I’ve ever seen for domestic use. If it can deal with something as powerful as lead and the most chlorine resistant bacteria then iron and manganese should not be a problem.

      Also remember that both iron or manganese are not harmful to the body. In fact, they both appear in food and are nutrients that the body needs. So trace amounts in your water (WITHOUT any harmful sediments, bacteria or lead) may not be such a bad thing.

      Hope this helps,
