The Frizzlife MP99 is a compact, affordable two-stage under-sink filter with a clever twist-change cartridge and a strong 1.4 GPM dedicated faucet. Tested to NSF/ANSI 42/53, its 0.5-micron media reduces lead, chlorine and 70-80 VOCs while keeping beneficial minerals, and an auto shut-off valve spares you from cutting the water supply at filter-change time. It's a tidy, low-cost choice for essential filtration with an easy maintenance routine.

Filtration and Certification
The Frizzlife MP99 uses a two-stage compound cartridge with 0.5-micron carbon media, a finer filtration precision than the 1-micron media common to many budget filters. Frizzlife states the full MP99 system has been tested by IAPMO R&T against NSF/ANSI 42 and 53, the standards covering taste and odor and health-related contaminants respectively. As Water Filter Portal wrote in its review of the sibling MK99, Frizzlife's under-sink systems 'remove heavy metals, lead, mercury and chlorine while leaving in essential minerals.'
That mineral retention is a deliberate design choice: the MP99 targets contaminants like lead, mercury, cadmium and 70 to 80 VOCs, plus chlorine, without stripping the calcium and magnesium that give water a pleasant taste. Like the other carbon systems here, it doesn't reduce fluoride or total dissolved solids, so it's aimed at the common municipal-water concern set rather than well-water or high-TDS situations.
Design and Installation
The MP99 is a compact two-stage unit, 5.5 by 5.5 by 13.5 inches, that mounts under the sink and feeds a dedicated brushed-nickel faucet included in the box. Having a separate filtered-water tap is a point in its favor over direct-connect systems like the Waterdrop 15UA, since it keeps unfiltered water available at the main faucet for tasks where filtration isn't needed.
Frizzlife designs the system for tool-free DIY installation with everything needed in the box, and the standout maintenance feature is the auto shut-off valve. As Water Filter Guru noted, Frizzlife's 'auto shut-off design makes filter changes fast and mess-free', you simply twist out the spent cartridge and twist in a new one without first shutting off the water supply, a genuinely convenient touch that few competitors match.
Filtered water costs about 9 cents a day
Reviewers consistently praise the MP99's convenience and value. Gravity Water Filters Reviews summarized it as delivering 'clean, pure and safe water with a quick twist-to-change cartridge and a dedicated faucet,' capturing the two things owners appreciate most: the simple maintenance and the dedicated tap. The replacement FZ-2 cartridge is inexpensive, working out to roughly $0.09 per day of filtered water.
The 1.4 GPM flow rate at 60 psi is also strong for a compact under-sink filter, so the dedicated faucet dispenses quickly rather than trickling. For a budget-priced system, the combination of fine 0.5-micron filtration, a dedicated faucet, fast flow and the no-shutoff twist-change cartridge gives it a polished, user-friendly feel that belies its low price.
Needs a drilled hole for the dedicated faucet
The MP99's two-stage design means narrower contaminant breadth than a three-stage system like the Aquasana or Clearly Filtered, and its filter life is shorter than long-life cartridges such as the Waterdrop 15UA's 24-month rating, so you'll change cartridges more often. The per-day cost stays low, but the maintenance frequency is higher than the longest-lived rivals.
It also requires a hole for the dedicated faucet, so you'll need a spare sink opening or to drill one, an extra install step that direct-connect systems avoid. And as with every carbon filter here, it doesn't address fluoride or total dissolved solids. None of these are flaws for its intended budget, essential-filtration role, but they cap its ambitions below the premium systems.
Adds a dedicated faucet the Filtrete lacks
Against the Aquasana Claryum AQ-5300+ and Clearly Filtered 3-Stage, the MP99 is far cheaper but offers less contaminant breadth and fewer formal certifications. Against the Waterdrop 15UA, it adds a dedicated faucet and the convenient twist-change cartridge, but the Waterdrop's 24-month filter life means less frequent maintenance. Against the Filtrete 3US-PS01, the MP99's no-shutoff cartridge swap is more convenient and it includes a dedicated faucet the Filtrete doesn't.
It slots in as the budget pick for buyers who specifically want a dedicated filtered-water faucet and the easiest possible filter changes. Those prioritizing the longest filter life lean to the Waterdrop; those wanting maximum breadth step up to the Aquasana or Clearly Filtered.
72 dollars for 0.5-micron filtration
At around $72 the MP99 delivers a surprising amount of polish: fine 0.5-micron filtration, IAPMO testing to NSF 42/53, a dedicated faucet, fast flow, and a maintenance routine that doesn't require shutting off the water. That feature set at this price makes it a strong value, particularly for buyers who specifically want a separate filtered tap.
The running cost stays low thanks to the inexpensive FZ-2 cartridge, though more frequent changes than the Waterdrop 15UA mean it's not the absolute cheapest to maintain over years. For a buyer who values the dedicated faucet and effortless cartridge swaps over the longest possible filter life, the MP99 represents excellent value in the budget tier.
Suits renters with tool-free installation
The Frizzlife MP99 is best for budget-minded households that want a dedicated filtered-water faucet, fine 0.5-micron filtration for lead, chlorine and VOCs, and the most convenient, mess-free cartridge change in the group. Its compact size and tool-free install suit DIYers and renters alike.
It's less suited to those who want the longest filter life, where the Waterdrop 15UA wins, or the broadest contaminant reduction including fluoride, where the Aquasana or Clearly Filtered are necessary. For essential, convenient, dedicated-faucet filtration on a budget, though, the MP99 is a smart, well-rounded choice.
