Frizzlife Under Sink Water Filter System

If you are looking for an under the sink water filter, here’s another space-saving variant that’s high on efficiency. This under sink, inline water filter by Frizzlife can precisely remove particles as small as 0.5 microns while retaining beneficial minerals for natural tasting water. They claim its 2-in-1 filtration system will free your water supply from pollutants like sand, sediment, rust, chlorine, heavy metals, and VOCs. While we haven't independently verified these claims, we did notice with their certifications. Frizzlife claims a 99% lead removal, which is true, however that removal rate, according to their IAPMO certification is based on the flow rate of 0.5 gpm, which is very low. We can't verify that Frizzlife can remove lead at 99% at a higher flow rate that most kitchen sinks operate at, so it may be more suited for use on a refrigerator or on a smaller tap. One advantage to the Frizzlife water filter is that this inline water filter unit is its straightforward installation process. With its compatible fittings, you will be done setting this up in no time and should be able to swap out filters on your regularly scheduled time intervals easily.

What Could’ve Been Better?

As mentioned earlier, this filter will not be suitable for hard water since it does not get rid of TDS. You will have to look for a separate RO membrane or invest in a water softener in addition to this under sink filter.

Another problem faced by a few buyers was the lack of instructions for the replacement process. Although the brand boasts fuss-free replacements, those without experience may find it confusing on the first go.

Moreover, unlike other brands mentioned on the list, the customer care team of Frizzlife earns no brownie points for its lack of enthusiasm and poor service. Their email responses are known to be different each time which speaks for the team’s careless attitude.

Again, this isn’t a significant concern, but you can never be sure when the product might malfunction, requiring you to seek help from the company.

Why Buy This Product?

This unit features a 2-stage advanced filtration system that removes fifty-eight different types of pollutants, including 99.99% lead, chlorine, and chemicals. Since the 2-in-1 cartridge consists of a sediment filter and a carbon block, both of 0.5-micron precision, even the smallest particles will stand no chance!

Even while removing such odor and taste degrading particles, it manages to retain useful minerals like calcium, magnesium, sodium, and potassium. While high volumes of these particles harden the water, consuming them in moderate amounts is beneficial for a healthy body. 

However, this factor can turn into a disadvantage for those with hard water supply. If limescale staining, difficult laundry, and pipe blockage are recurring concerns, you will have to look into some water softeners instead.

2. Multi-functional Design

Despite being a budget-friendly option, this under sink water filter serves many household purposes. You can either connect it to your refrigerator or icemaker, according to your convenience. Additionally, you can get your hands on the Frizzlife ST3 faucet and combine it with the filtration system.

Thus, you will be able to enjoy water in its purest form from all the sources in your kitchen. No more pitchers and bottles to refill after every use. Phew!

3. Easy Installation and Replacement

Installing this unit is a no-brainer. Due to its compatible fittings and adequate installation kit, you won’t have to spend hours fixing it under the sink. In fact, it is a beginner-friendly process that will not take you more than 3 minutes. Hence, you don’t need to worry about spending extra bucks on professional plumbing services.

Unlike the CuZn UC-200, you need not replace the entire unit once the filter cartridge expires. The cartridge is separate from the main plastic body, allowing you to save money and the environment. According to the brand, your savings will shoot up to 70% with this under sink water filter.

4. Convenient Auto Shut-off Mechanism

Speaking of replacements, you will have to change the inner filter cartridge on a yearly basis. However, to reduce the hassle, the filter head sports an auto water shut-off switch. So, in times of replacements or maintenance, you don’t have to stop the entire water supply. With a mess-free and tool-free replacement process, this unit has got you covered!

5. Third-party Tested and Certified

In case you’re still doubtful about the quality of the product, you’ll be relieved to know that third-party companies have tested this Frizzlife water filter. After much research, the product is NSF/ANSI 53&42 certified. 

This implies that the filter is certified to eliminate water pollutants that can degrade your health. Such hazardous particles include lead, fluoride, arsenic, and many more. Moreover, the unit is proven to filter out chlorine and other particles that contribute to foul taste and odor in water.

6. High Water Pressure

Unlike its competitors, this filter offers a maximum flow rate of 2 gallons per minute. Hence, households with large families can enjoy the goodness of pure and healthy water without missing out on high water pressure. Even if most water sources in the house are engaged, reduced water pressure will never be a matter of concern.
