1.These harmonized values were agreed upon by representatives of USEPA and Health Canada for the purpose of evaluating products to the requirements of this Standard.

2.Influent challenge levels are average influent concentrations determined in surrogate qualification testing.

3.Maximum product water level was not observed but was set at the detection limit of the analysis.

4.Maximum product water level is set at a value determined in surrogate qualification testing.

5.Chemical reduction percent and maximum product water level calculated at chloroform 95% breakthrough point as determined in surrogate qualification testing.

6.The surrogate test results for heptachlor epoxide demonstrated a 98% reduction. These data were used to calculate an upperoccurrence concentration which would produce a maximum product water level at the MCL.

CHP-04AL, CHP-04AR, CHP-04AU specifications

Coway, a renowned leader in water filtration technology, has designed an impressive lineup of water purifiers with the models CHP-04AL, CHP-04AU, and CHP-04AR. These purifiers are celebrated for their advanced features, cutting-edge technologies, and user-centric designs that ensure safe and clean drinking water.

One of the standout features across the CHP-04 series is the multi-stage filtration process that ensures optimal water quality. Each model is equipped with a robust filtration system that includes a pre-filter, an activated carbon filter, and a reverse osmosis membrane. This multi-layered approach effectively removes harmful contaminants, heavy metals, and unwanted odors, ensuring that the water is both pure and refreshing.

The CHP-04AL, CHP-04AU, and CHP-04AR models share a similar sleek design, highlighted by a compact footprint and modern aesthetics that blend seamlessly into any kitchen or office environment. Their user-friendly interfaces come with easy-to-read indicators, making operation intuitive for users. Additionally, these models feature adjustable dispensing temperatures, allowing users to select the perfect water temperature for drinking or cooking, be it cold, hot, or at room temperature.

Another remarkable technology found in the CHP-04 series is the eco-friendly energy-saving mode. This feature reduces power consumption when the purifiers are not in use, making them an environmentally conscious choice. The smart design also includes a 360-degree rotating tap, enhancing accessibility and convenience during usage.

Durability and maintenance are crucial considerations for any water purifier. The CHP-04 models are constructed with high-quality materials, ensuring longevity and reliability. Maintenance is simplified with easily replaceable filters, and the system notifies users when it’s time for a filter change, promoting consistent water quality.

The Coway CHP-04AL, CHP-04AU, and CHP-04AR stand out not only for their impressive filtration capabilities but also for their commitment to quality of life. With these models, users can enjoy the peace of mind that comes with knowing they have access to clean, safe, and tasty water at all times. Whether for a family kitchen or a busy office, these purifiers redefine hydration, making them an essential addition to any environment focused on health and well-being.
