Why Would I Use a pH Balancing Filter?

Why Would I Use a pH Balancing Filter?

Reverse Osmosis is one of the few water treatment technologies that filters virtually all contaminants from water, both organic and inorganic. If Reverse Osmosis did not filter out the inorganic it would miss many of the inorganic contaminants such as Nitrates, Arsenic and Chromium 6. However, the same high performance filtration that filters harmful contaminants also filters healthy minerals from water, including calcium.

Because the minerals have been filtered from the water, Reverse Osmosis water is inherently more acidic than tap water because of all the impurities it removes. The pH Balancing Filter adds the healthy minerals such as Calcium and Magnesium back into the water and in the process brings the pH level closer to neutral.

Thank you for adding a pH filter to your great line of products

A. What is the nominal life in gallons and time?
B. Why is the life impacted by local water conditions, since the pH filter is downstream of the RO unit which produces the cleanest water possible, and the RO in fact changes the pH??
C. I have a whole house water softener. Does this affect the pH balancing filter operation?
d. Do you have a pH equation similar to the TDS equation which tells the effectiveness.
E. For cost effective use, how do we monitor operation to know when to change the filter. Is it as simple as measuring the pH at the outlet versus the inlet?
F. What is the downside? Any maloperation danger?
G. Is the pH of the effluent 7.0? How does the filter produce/ “control” that? What is the plus/minus variability on the effluent pH?

Thank You!

A. The average life of the pH filters is Annual replacement.

B. If the incoming water is already at high acidic levels or low pH, then RO filtration may reduce the pH to lower levels than expected. This would cause the pH balancing filter to work harder, reducing its expected life span.

C. A water softener would have little to no effect on the pH filter as they are installed post-RO, which removes the majority of any sodium generated by the water softener.

D. Unfortunately, there is no equation to determine the effectiveness of a pH filter. They simply bring the acidic levels of the RO system to a more balanced level.

E. The easiest way to know when to change the filter is by measuring the pH of just the outlet. Once the pH starts to drop below neutral levels, then it is about time to order a replacement. If a pH test is unavailable, then following the recommended schedule would be best or by a simple taste test of the water. Acidic water may have a slight metallic taste to it.

F. There is no danger associated with the pH filters. They simply work to balance the pH levels in the water created by the RO system until the media inside is spent.

G. These filters should raise the pH of RO water to a more balanced level of 7 to a maximum of 8. This level is controlled by the slow release of minerals such as calcium and magnesium into the water. The media of the filter utilizes the acidity of the water to maintain a balanced pH level with a +/- 0.5.
