How the Frizzlife SK99 Performs

To determine how well the SK99 works, we’ll examine its filtration effectiveness, flow rate, certifications, and more based on available information.

Filtration System

The core of this under-sink filter is its three-stage filtration process:

Stage 1 uses an activated carbon block filter to reduce chlorine, odors, volatile organic compounds (VOCs), and other chemicals through a process of adsorption.

Stage 2 utilizes an ion exchange resin filter to capture heavy metals including lead, mercury, copper, cadmium, and zinc.

Stage 3 features a 0.5-micron filter that traps any remaining particulate matter down to 0.5 microns in size.

This system allows the removal of a wide spectrum of contaminants from water. According to Frizzlife, the SK99 can eliminate 99% of impurities thanks to this combination of filters.

While it doesn’t fully purify water like reverse osmosis systems, it’s worth mentioning in this Frizzlife SK99 review that customers say the product makes a noticeable improvement in the taste, odor, clarity, and safety of the water.

Water Flow Rate

The Frizzlife SK99 is designed to deliver a high flow rate for an under-sink system.

It has a rated service flow of 2.0 gallons per minute (GPM) at 60 PSI. In real-world use, the flow rate ranges from 1.8 to 2.0 GPM based on home water pressure.

This high flow provides a steady stream of filtered water without much waiting. The SK99’s flow rate surpasses cheaper under-sink models that can be quite slow.

It’s important to mention in this Frizzlife SK99 review that consistent water flow is useful for filling up glasses or pots without delays, according to users. This makes the SK99 more convenient to use daily.

Filtration Certifications

The Frizzlife SK99 has been independently tested and certified to ensure filtration safety and effectiveness.

It is certified by NSF International against standards 42 and 53. NSF 42 certification verifies the filter reduces aesthetic contaminants like chlorine for better taste and odor. NSF 53 certifies the system reduces health contaminants like lead and mercury.

Undersink systems can sometimes be challenging to install. But the SK99 is designed for quick, easy setup without a plumber.

Reviewers confirm the installation is straightforward and can be handled by most DIYers without issues. The quick connect fittings help simplify the process.
