Product description
If you’re looking for a countertop gravity filter that targets specific contaminants, the Culligan MaxClear is worth a serious look on paper. It’s built around carbon and a ceramic filter and is positioned as a certified gravity system designed to reduce microplastics, lead, and total PFAS.
That combination is the big story here. Gravity filters can be simple and low-hassle—no plumbing, no electricity—but not all of them are aiming at the same headline contaminants. This one also keeps the focus on “everyday” drinking water capacity, which matters if you don’t want to refill constantly.
Key takeaways: what matters most
The MaxClear uses a gravity setup and an included ceramic filter with carbon-based filtration to help reduce microplastics, lead, and total PFAS. It’s also described as NSF/ANSI certified to NSF/ANSI-42 standards to reduce those harmful contaminants.
One nuance you should keep in mind: the ceramic filter is not designed to reduce TDS (total dissolved solids). So if you test TDS, readings may stay the same or even rise slightly—while the water can still be cleaner and safer in terms of the targeted contaminants.
What you’ll notice day to day
This is a countertop gravity water filter system with a stainless-steel dispenser and spigot, plus a stand for use. Because it doesn’t require electricity or plumbing, setup is mostly about placement and filling a reservoir/upper chamber when you want fresh drinking water.
In practical terms, it’s the kind of filter you use like a mini water station: fill it, let gravity do the work, then pour into a glass. It’s also designed for storage when you’re not using it—described as nesting within itself to store at less than 12 inches tall.
If you’re feeding a small household, the stated capacity is positioned as enough daily drinking water for up to 3 people, which generally translates to fewer refill cycles than smaller gravity models.
Where it shines (and where it may not)
It makes sense if your priority is “certified reduction” of several difficult-to-handle contaminants in one gravity filter system—especially microplastics, lead, and total PFAS. The fact that it’s positioned as NSF/ANSI-42 certified is also a meaningful differentiator for shoppers who want more than marketing language.
Worth considering that the focus isn’t on lowering TDS. If your main goal is clear lower TDS numbers on a meter (or you’re chasing specific TDS performance), you may find this doesn’t align with what you’re trying to measure.
Compatibility and filter choices
This model is also described as compatible with Berkey water filters inside Culligan gravity dispensers, including Berkey Black BB9-2 Water Filter Replacement. It’s also stated to be compatible with replacement filters from Boroux, ProOne, Doulton, Purewell, and Waterdrop.
That compatibility angle can be helpful if you already own or prefer a particular replacement ecosystem. Still, you’ll want to double-check the specific replacement model you’re planning to buy so you’re matching what fits your dispenser setup.

Is it worth it?
Buy it if you want a countertop gravity filter with a clear, certified target: microplastics, lead, and total PFAS, and you’d like a setup that doesn’t need plumbing or electricity. It’s also a reasonable pick if you value a stainless-steel dispenser design and want a system that should cover daily drinking water for a small household without constant refilling.
Skip it or at least reconsider if lowering TDS readings is your primary requirement, since the ceramic filter is not designed for that and TDS readings may not drop. Also, if you’re expecting a gravity unit to behave like a specialized whole-home or high-end lab-grade filtration setup across every metric, it may feel more like a targeted, practical solution than a universal one.
Mini FAQ
Does it require plumbing or electricity?
No—this system is described as requiring no electricity or plumbing. You place it and fill it to let gravity filter the water.
Will it lower TDS?
Not necessarily. The ceramic filter is not designed to reduce TDS, and readings may stay the same or slightly rise.
What contaminants is it designed to reduce?
The product description states it reduces microplastics, lead, and total PFAS.
Is it compatible with Berkey filters?
It’s described as compatible with Berkey water filters that fit inside Culligan gravity dispensers, including Berkey Black BB9-2.
What’s included in the box?
The description specifies it includes 1 ceramic filter.
