Countertop Water Filter System
...Model: Pure Water Products 77, 77S

Who Needs It?

A quality carbon block countertop filter is for those who want not only better tasting water but a high quality of purity as well. Being a countertop means that it is much bigger than a faucet mount filter and hence there is more carbon block material filtering the water, improving the removal of pollutants. It's not the highest level of removal of pollutants. A water distiller or a reverse osmosis filter can give you higher, but carbon block filters much faster than these slower methods. The countertop model as opposed to the under sink model is great for those who have adequate countertop room. The Pure Water Products 77 or 77S are single-housing units made with top quality parts. They can use a wide range of cartridges and be designed for your particular needs.

Disadvantages

The disadvantages of the countertop water filter system: model Pure Water Products 77 or 77S are the same as the disadvantages of any carbon filter. There are four elements that affect the quality of filtration: 1) The amount of time that the water is in contact with the carbon, 2) The density of the activated carbon, 3) The quantity of the carbon, and 4) The amount of water that has gone through the filter, which becomes increasingly ineffective the longer it is used until it needs to be replaced. In short, there is a relative element to the filtration. It is relative to these four factors. As opposed to a purification system such as distillation which removes all impurities completely, except for VOCs which are usually remove by other filters. And as opposed to reverse osmosis which removes more pollutants but not as many as distillation, though ro is also slow.

The second disadvantage of carbon filters is that they cannot remove many micro organisms such as bacteria and viruses. They cannot remove toxic minerals, nitrates, and soluble salts.

What Contaminants Does It Remove?
