Frequently asked questions
What is a specialty water filter?
A specialty water filter uses advanced filtration technologies, such as deionization and reverse osmosis, to provide high-quality water filtration. These filters are designed to remove impurities and often purify water to its purest form.
Specialty water filters are ideal for healthcare environments like:
- Dentist offices
- Assisted living facilities
- Hospitals
- Research laboratories
These filters ensure clean, safe water for environments that require the highest standards of purity.
How do you change a water filter?
Changing a water filter is a simple process, but it varies depending on the type of water cooler or filtration system you have.
Here’s a general guide:
- Turn off the water supply: Before replacing the filter, make sure to turn off the water supply to avoid spills.
- Locate the filter: Find the filter compartment. It’s typically located at the water source under the sink.
- Remove the old filter: Twist or pull the old filter out, depending on the model.
- Insert the new filter: Align the new filter with the slot and insert it, ensuring it fits securely.
- Turn on the water supply: Once the new filter is in place, turn the water supply back on.
- Flush the filter: Run water through the system to ensure proper installation and remove any loose particles.
For best results, replace your water filter regularly as recommended by the manufacturer.
When renting a water cooler from Culligan Quench, a certified service technician will change out your filter for you at least once a year. One filter change is included in your monthly rental fee.
How do you filter fluoride out of water?
The most effective method to remove fluoride is a reverse osmosis filter, which significantly reduces fluoride levels in your drinking water. This is especially important in areas with naturally high fluoride concentrations. Culligan Quench point-of-use machines work by passing water through a semipermeable membrane that removes contaminants, including fluoride, ensuring you have clean, fluoride-free water.
How does a reverse osmosis filter work?
A reverse osmosis filter works by using applied pressure to push water through a semipermeable membrane. This process forces water to flow in the opposite direction of natural osmosis—moving from an area with a high concentration of contaminants to one with a lower concentration. As the water passes through the membrane, contaminants like dissolved salts, chemicals, and impurities are trapped, while clean, purified water is allowed to pass through. The result is water free from harmful substances. Click here to learn more about how reverse osmosis systems work.
