The Short Answer on the IceJoy 2.25G

Best for: you want a stainless steel gravity water filter with no electricity or plumbing and a 0.01-micron membrane for fine particulate reduction.

Choose the IceJoy 2.25G if that setup matches your kitchen or backup-water needs, at around $108.98.

• Pro: Its stainless steel body is the material most of the screened listings also state.
• Pro: The 6,000-gallon filter life is at the high end of the listings that state a lifespan.
• Con: It does not reduce TDS, so you should skip it if you want dissolved solids removed from the water.
• Con: The 2.25-gallon capacity suits moderate batch use, but it will not reduce refill frequency as much as a larger tank.

Don’t buy this if: you need a gravity filter that reduces TDS or you want a larger 3.25-gallon batch size for heavier daily use.

Price assessment: Around $108.98 is fair for a stainless steel gravity filter with a 0.01-micron membrane and a stated 6,000-gallon life.

Full Specifications for this Gravity Water Filter

Filter pore size most separates this Gravity Water Filter. It measures the size of the openings that limit what particles can pass through.

Before You Buy: Countertop Gravity Filter Checklist

The first thing to check is whether a 2.25-gallon tank fits your daily water use, because smaller capacity means more refills.

• ☐ Confirm the tank size — 2.25 gallons. If your household drinks through it quickly, you will refill it more often and lose the convenience of a countertop gravity filter.
• ☐ Check the filtration rating — 0.01 micron. If you need a coarser or different filtration target, this unit may not match the water quality job you have in mind.
• ☐ Confirm the contaminant list — chlorine, PFAS, fluoride, heavy metals, microplastics, bad taste, odors, and bacteria. If you need a reduction claim that is not listed, you may end up with water that does not address that problem.
• ☐ Budget for the installation setup — no electricity and no plumbing. If you wanted a powered or plumbed system, this one will not replace that setup.
• ☐ Check the included hardware — faucet included. If you need a different tap arrangement, you may have to modify the setup after purchase.
• ☐ Confirm the filter life — 6,000 gallons. If you want a longer service interval, you will be changing filters sooner than you planned.

Do not buy this if you need a larger batch size than 2.25 gallons or if you need a contaminant claim that is not stated here.

What These Specifications Let You Do

What a 0.01-micron membrane can filter out

IceJoy 2.25G uses a 0.01-micron membrane, so it targets very fine particles and dissolved contaminants that coarser gravity filters leave behind. That size also makes the filter relevant if you want a countertop gravity filter for bacteria and protozoa concerns, because the category reference point for that job starts at 0.2 µm and this listing states a much finer pore size.

The fine opening is what gives you a tighter barrier, but it also means the filter is built for cleanup work rather than fast throughput. Think of it like a screen with smaller holes: more gets held back, while the water path is narrower. IceJoy also states 99.99% removal of microscopic impurities, which tells you the unit is aimed at very small debris and contamination, not at changing the water’s dissolved solids.

Which contaminants this gravity filter reduces

IceJoy 2.25G states fluoride and PFAS reduction, so those are not just marketing claims here. The composite filter also includes a hollow fiber UF membrane, a silver-ion membrane, and an activated carbon block, which gives you a single gravity filter aimed at chlorine, bad taste, odors, heavy metals, microplastics, and bacteria.

The important limit is that this model does not reduce TDS, so it leaves dissolved minerals in the water instead of stripping everything out. That is the trade-off many people want in this category: cleaner water with minerals preserved. If you want lower fluoride and PFAS while keeping mineral content, this listing gives you that combination in one unit, but it does not promise a lower total dissolved solids reading.

Why gravity-only use works without power or plumbing

IceJoy 2.25G runs on gravity alone, so you can use it without electricity or plumbing. The upper chamber takes unfiltered tap water or outdoor water, which makes it useful for a kitchen counter, a cabin, or backup water handling when power is unavailable.

The 2.25-gallon capacity suits smaller batch use, where you want a countertop fill-and-wait setup without constant refilling. The stainless-steel body, two filters, and included faucet make the layout straightforward for a household that wants a plumb-free gravity filter, while the 6,000-gallon filter life reduces how often you need to replace the elements.

The IceJoy 2.25G Against Similar Gravity Water Filters

IceJoy 2.25G is the cheapest of the six at around $108.98, and its 0.01-micron membrane matches the finest figure stated among the products here.

• Compared with CO-Z, IceJoy costs the same and states the same 2.25-gallon capacity. The tie leaves capacity as the deciding point only if you need that batch size.
• Against Purewell 2.25G, the pore rating is also 0.01 microns. That means the filtration opening size does not separate them.
• FACHIOO lists a 3.25-gallon tank, while IceJoy stays at 2.25 gallons. Choose FACHIOO if fewer refills matter more than the smaller footprint implied by the lower capacity.
• PHOENIX states NSF/ANSI 42 and 372 certification, while IceJoy does not state either standard. Pick PHOENIX if certified chlorine, taste, odor, or material claims matter to you.
• Purewell Gravity Water Filter System includes a transparent water-level window, and IceJoy does not list one. That makes the Purewell model easier to monitor without opening the chambers.
• IceJoy ranks third on buyer rating in this group, with a 4.2 average from 321 ratings. It trails the two higher-rated options on reported buyer sentiment.

If you want the larger 3.25-gallon batch size, FACHIOO is the better pick. It trades the smaller 2.25-gallon format for more stored water between refills.

Setting Up This Gravity Water Filter, and What Support Covers

What IceJoy 2.25G needs before it runs

IceJoy 2.25G needs gravity and water. It is a gravity-powered filter with no electricity and no plumbing.

1. Unpack the stainless steel body and the two filters.
2. Fit the composite filter assembly into the chamber that holds unfiltered tap or outdoor water.
3. Place the upper chamber above the lower chamber so gravity can move water through the 0.01-micron membrane.
4. Fill the upper chamber with water and wait for filtered water to collect below.
5. Match any replacement filter element to the same 0.01-micron format, and match a spigot gasket to the outlet size already fitted on the unit.

Warranty and support checks for IceJoy 2.25G

Warranty cover differs by seller and country.

• Confirm the return window before it closes, because the 0.01-micron membrane and the composite filter are the parts most tied to filtration performance.
• Confirm whether replacement filter element availability matches the 6,000-gallon filter life, because worn media will affect use long before the stainless steel body does.
• Confirm whether a spigot gasket is included or sold separately, because the faucet outlet is a leak point if the seal does not fit.
• Confirm whether a priming washer is needed for the filter elements, because some elements need that part before first use and it is not stated here.

When it arrives, inspect the faucet seal and the filter elements first, while a return is still possible.

IceJoy 2.25G Buying Questions Answered

What the 0.01-micron membrane changes

That tighter pore size is what supports the unit’s claim set for microplastics, heavy metals, fluoride, and PFAS, while the 6,000-gallon filter life keeps replacement frequency lower than many shorter-life listings.
