FACHIOO FSS3A-TB-F Gravity Water Filter Review: 3.25 Gallon Countertop Gravity-Fed Capacity

Where the FSS3A-TB-F Fits

If your counter has room for a 23″W footprint, a gravity-fed water filter can sit there without forcing you into a smaller batch size. That is the practical trade-off this format creates for apartment kitchens and shared spaces.

FACHIOO FSS3A-TB-F fits that setup with a 3.25 gallon capacity and a stainless steel stand. The included stand matters because it gives the countertop system its raised layout without adding a separate purchase.

We screened 28 Gravity Water Filters and this is one of 15 chosen for a full review. Full reviews go to the most-rated products that pass screening, at most 2 per brand. This one has 467 buyer ratings, the 4th most of the 28 screened. If you want a Gravity Water Filter for a small kitchen or apartment counter, this review is for you.

The Short Answer on the FSS3A-TB-F

Best for: you want a 3.25-gallon countertop gravity filter with a 9.5-inch height and no electricity or plumbing.

Choose the FSS3A-TB-F if you want that setup; it is around $108.99.

• Pro: The 3.25-gallon capacity supports a larger batch than a small countertop tank.
• Pro: The 9.5-inch height helps it stay compact on a counter.
• Pro: NSF/ANSI 42 certification covers chlorine, taste, and odor claims.
• Con: The listed capacity is less than a full-day drinking-and-cooking need, so a high-use household will still refill it during the day.
• Con: The 4.2 average from 467 buyer ratings leaves more uncertainty than a product with a stronger buyer response.

Don’t buy this if: you need a gravity filter to cover a full day of home drinking and cooking without refilling.

Price assessment: $108.99 is fair for a stainless-steel gravity filter with NSF/ANSI 42 certification, four filters, and a stand.

The Specifications That Matter for This Countertop Gravity Filter

Capacity is the deciding spec that most separates FSS3A-TB-F. It measures how much water the filter can hold at one time.

Performance: What the Specs Deliver

3.25-Gallon Capacity for a Small Apartment Counter or Kitchen

FSS3A-TB-F gives you 3.25 gallons, which is enough for a small apartment counter or a small kitchen without constant refills. For a family dinner, the working estimate is about 0.9 to 1.5 evenings at 80% usable capacity, so it covers one lighter evening and falls short of a full heavy-use stretch.

That capacity also changes the trade-off if you want a filter for daily household drinking. The same 3.25-gallon volume is less than one day for a home that drinks and cooks from the filter all day, so you save counter space versus a larger unit but give up refill slack. Choosing a smaller tank than your use pattern demands costs time, because you refill more often and break up meal prep or shared use.

How the two fluoride filters deliver 90% fluoride reduction

FSS3A-TB-F includes two white fluoride filters and states 90% fluoride reduction, so you can target fluoride reduction directly instead of relying only on carbon filtration. That matters if your main concern is fluoride, because the listing separates those filters from the two black activated carbon elements used for chlorine, taste, odor, and heavy metals.

The fluoride side is narrower than the capacity story, because it addresses one contaminant group rather than household volume. If fluoride is your priority, this model gives you a stated reduction figure to compare against your needs; if you want a broader contaminant plan, you still need to weigh the NSF/ANSI 42 certification and the listed carbon elements alongside it. Choosing without that split can cost you money on a feature you do not need, or leave you short on the reduction you expected.

Gravity-fed countertop design with no electricity or plumbing required

FSS3A-TB-F uses a gravity-fed countertop design with no electricity or plumbing required, so you can place it where you have counter space and start using it without a powered install. The 9.5-inch height helps here, because it keeps the unit compact enough for tighter counter layouts while still holding a 3.25-gallon batch.

The same countertop format also sets a practical limit: this is a pour-and-wait setup, not a plumbed system with continuous output. The metal spigot, built-in water level tube, and included stand make the setup self-contained, but the 23-inch width means you should measure the counter span before you order. If you place a gravity filter too large for the space, you lose both room and convenience, and the return becomes a fix for a sizing mistake.

How the FSS3A-TB-F Compares to Other Gravity Filters

The 3.25-gallon capacity gives it more batch size than the smaller-capacity rivals we compared, while the $108.99 price stays tied with three competitors and only $0.01 above two others.

• FSS3A-TB-F is the largest-capacity listing among the options that state a size, at 3.25 gallons. CO-Z states 2.25 gallons, so the FACHIOO unit gives you a larger reserve between refills.
• Purewell 2.25G and FSS3A-TB-F both sit at the same $108.99 mark. Price does not separate them here, so capacity is the useful difference.
• PHOENIX GRAVITY also matches this model at $108.99 and states NSF/ANSI 42 plus NSF/ANSI 372. The FACHIOO listing instead adds fluoride filters and a 90% fluoride-reduction claim, which is the more relevant detail if fluoride is your target.
• Purewell Gravity Water Filter System matches the price at $108.99, but its listing highlights a transparent water-level window instead of this model’s metal spigot with built-in water level tube. If you want a visible level cue built into the faucet side, FSS3A-TB-F is the more direct match.
• IceJoy 2.25G is $0.01 cheaper, and that gap is too small to matter on its own. The more useful distinction is that FSS3A-TB-F states four filters, while IceJoy’s summary here does not give the same filter count.
• On buyer ratings, FSS3A-TB-F sits third in this six-product set at 4.2 from 467 ratings. That places it behind the higher-rated Purewell 2.25G and PHOENIX GRAVITY, so rating does not favor this pick.

If you want the strongest fluoride-focused alternative, PHOENIX GRAVITY is the better pick. Its listing pairs NSF/ANSI 42 with NSF/ANSI 372 and specifically names microplastics and PFAS reduction, which is a different target set from this FACHIOO model.

Where this price sits among similar Gravity Water Filter products

FACHIOO’s 3.25-gallon capacity matters more than the 9.5-inch height if you want fewer refills.

At around $108.99, the FSS3A-TB-F sits in line with the similar Gravity Water Filter products we compared it against, which range from $108.98 to $108.99. You are paying for a stainless steel countertop unit with four filters, a stand, and a metal spigot, so the price makes sense if you want that package rather than a bare-bones setup.

Choose it if you want a gravity-fed countertop filter with NSF/ANSI 42 certification, 90% fluoride reduction, and a 3.25-gallon tank. If you need a unit for a full day of heavy household drinking, the capacity is not enough for that job; if you are covering a small apartment counter or a family dinner, it is the better fit.

The 4.2 average from 467 buyer ratings adds context, but the deciding question is whether your counter can give up 23 inches of width and 9.5 inches of height. If that space works, the size and included stand make the purchase easier to justify; if not, the capacity will not offset the footprint.

From Delivery to First Use with This Gravity Filter

What it takes to get FSS3A-TB-F running

You need a countertop space that can hold a 23-inch-wide, 9.5-inch-tall gravity-fed system with its stand.

1. Unpack the upper chamber, lower chamber, stand, and four filters from the box.
2. Place the non-slip stainless steel stand on a flat countertop with room for the 23″W footprint.
3. Install the two Black Activated Carbon Elements and the two White Fluoride Filters in the chamber openings.
4. Fit the metal spigot with its built-in water level tube, then tighten it so the outlet lines up with the lower chamber.
5. Fill the upper chamber by gravity and wait for the first filtered water to collect in the lower chamber.

If a replacement filter element is needed later, it has to match this four-filter layout, and a fluoride filter element has to match the fluoride stage already listed here.

Warranty and support: what to check

Cover differs by seller and country.

• Confirm the return window before it closes, because the four filters and the metal spigot are the parts most likely to disappoint if the fit is off.
• Confirm whether replacement filter elements are stocked for this model, because the listed filtration setup uses four separate elements.
• Confirm whether a spigot gasket is included or sold separately, because the metal outlet is a leak point on any gravity filter.
• Confirm whether the fluoride filter element is available as a replacement, because the fluoride stage is part of the stated reduction claim.

On arrival, assemble FSS3A-TB-F and fill it once while the return window is still open.

The FSS3A-TB-F: Remaining Questions

Will FSS3A-TB-F fit under cabinets on your counter?

Yes, FSS3A-TB-F is 9.5 inches tall, so the height is the figure to compare against your cabinet clearance. Its 23-inch width and 9.5-inch depth also matter if your counter space is tight.

Does FSS3A-TB-F have enough capacity for a small kitchen?

FSS3A-TB-F holds 3.25 gallons, which is the figure to use if you want fewer refills during a small-kitchen routine. That size also makes sense for a family dinner, where the worked-out use case points to about 0.9 to 1.5 evenings depending on how much water you draw.

What filtration claims does FSS3A-TB-F make?

FSS3A-TB-F is listed with NSF/ANSI 42 certification and a 90% fluoride reduction claim. It also states reduction of chlorine, heavy metals, sediment, taste, and odor, so you get both a standards-based claim and a specific contaminant claim.

Is the metal spigot included with FSS3A-TB-F?

Yes, the metal spigot is included, along with a built-in water level tube. The included components also list one upper chamber, one lower chamber, four filters, and one stand.

Should you buy FSS3A-TB-F for daily high water use?

Not for a full day of heavy drinking and cooking. The 3.25-gallon capacity is short of the worked-out 3 to 4 gallons that job takes, so you should look for a larger reservoir if that is your main use.

Is the FSS3A-TB-F Right for You?

Final Verdict on the FSS3A-TB-F

You should choose the FACHIOO FSS3A-TB-F if you want a 3.25-gallon gravity water filter for a small counter and do not need a tall unit. It is around $108.99, and its 9.5-inch height keeps the profile low.

The strongest data point here is the 3.25-gallon capacity. That size is useful when you want fewer refills than a 2.25-gallon countertop unit, but it still does not cover a full day for a high-use household.

Skip it if: you need one filter to carry a full day of drinking and cooking, or you want enough stored water for a weekend outage.
