Reverse Osmosis Filter vs. Refrigerator Filter: Which is Best?

The kind of water filter that you use at home can have a great effect on your family’s health. Many people rely on the filter in their refrigerator to provide their family will filtered water. This is an easy option, but can it provide sufficient health benefits, adequate convenience, and savings? A reverse osmosis (RO) filter is an excellent alternative that will check all of these boxes.

The RO Filtration Method

The contaminants in your water supply all have a size that’s measured in microns. Many household water filters cannot remove contaminants of a smaller size. The RO system uses a reverse osmosis technique to remove impurities that a slightly larger than a single water molecule. The water is forced through a filter membrane at high pressure to ensure that the water is clean. Many homeowners also supplement this system with a UV filter to ensure that any persistent parasites and viruses are removed.

RO Filtration Performance

The water coming into your home may look clean, but there are contaminants that cannot be detected by our senses of sight, taste, and smell. There are Total Dissolved Solids (TDS) that could contain toxic contaminants, such as lead, sulfur, arsenic, mercury and chromium 6, that may be in your water supply. Other threats include microscopic spores and bacteria that cannot be detected without laboratory testing. All of these contaminants could damage your health, and even municipal water supplies could be affected. The EPA has standards for TDS, your local water plant may remove these contaminants before they reach your home, but trace amounts could still be present. The refrigerator filter will not be able to remove these remaining contaminants. An RO filtration system can efficiently remove all of these contaminants that other lesser water filters will miss.

Minimum RO Unit Maintenance

It’s advisable to change the filter in your refrigerator every six months. This is generally depends on the indicator light that will let you know when you need to change the filter. If the indicator light is missing or malfunctioning, you may need to rely on your senses to tell you when it’s time to change the filter. Over time, refrigerator filters will become less efficient, and they will require more maintenance. This will all cost money that could have been spent on an RO filtration system that will be far more effective and require very little maintenance.

Consistent Filtration Performance and Reliability

Despite regular maintenance and cleaning, impurities can still enter your drinking water. The filter may be fine, but the fridge water dispenser could be contaminated with bacteria, such as yeasts, molds and E. coli, from food that’s been stored in the refrigerator. The contamination can vary a great deal, and if you’re concerned about the water quality, you need to get it tested. An RO filtration system will work consistently for years without compromising on the water taste and quality. For all of these reasons, an RO unit is the best choice for any homeowner interested in health and wellbeing.
