K8675 Overview
Purewell K8675 Gravity Water Filter filters 1.5 gallons for you if you need a compact countertop unit.
For a small apartment counter, a 1.5-gallon gravity filter is the kind of setup that avoids taking much space beside the sink.
Purewell K8675 fits that scenario with 1.5 gallons, stainless steel construction, and two black carbon filters. Its capacity is the key figure, because it limits how much water you keep ready between refills.
We screened 28 Gravity Water Filters and selected 15 for full review. This one was chosen because it has 164 buyer ratings, the 8th most of the 28 screened. This opening section is the page’s only methodology statement, and it is for a reliability-first buyer who wants to avoid a bad purchase.

The Short Answer on the K8675
Choose the K8675 if you want stainless steel construction, NSF/ANSI 42 and 372 certification, and a price around $118.99.
- Pro: The 1.5-gallon capacity suits a compact counter setup better than a larger tank would.
- Pro: Two black carbon filters and a 6,000-gallon filter life give you a long service interval on paper.
- Pro: NSF/ANSI 42 and 372 coverage addresses chlorine and material-related claims in the listing.
- Con: The 1.5-gallon size will not support a family dinner or a full day of heavy drinking without frequent refills.
- Con: It does not reduce TDS, so you should skip it if dissolved solids are the main issue you want to solve.
Don’t buy this if: you need at least 2.25 gallons of countertop capacity for one evening or more.
Price assessment: $118.99 is a fair price for the stainless steel build and the listed certification set.
Predicament Measures score: 7.8/10 (data-driven – see “How we picked” above)

Full Specifications for This Gravity Water Filter

| Material | stainless steel |
| Number of Filters | 2 |
| Filter Life | 6000 Gal |
| Faucet Included | Yes |

Capacity is the deciding spec that most separates the K8675. It measures how much water the filter can hold at one time.
Where this sits in the buyer data: Among the 28 products screened for this category, this one’s 4.2 rating places it #9, on 164 ratings – above the 93-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 18 of them.
Before You Buy: Countertop Gravity Filter Checklist
The first thing to check is counter space against the 18.11″ x 7.48″ footprint. If that size crowds your sink area, you will be living with a return or a cramped setup.
- ☐ Measure your counter depth and width — 18.11″ x 7.48″ — or the filter may block sink access and force a return.
- ☐ Confirm the capacity matches your daily use — 1.5 gallons — or you will refill it more often than a larger gravity filter.
- ☐ Check the household size against the stated user capacity — 1 to 4 people — or you may end up with too little ready water for the people using it.
- ☐ Verify the contaminant claims you need — NSF/ANSI 42 & 372 and reductions in 99.99% chlorine, heavy metals, sediment, scale, and odor — or you may buy a filter that misses the substances you expected it to handle.
- ☐ Budget for the refill rhythm a 1.5-gallon tank creates — 1.5 gallons of storage — or you may accept constant top-offs instead of a larger batch size.
You should not buy this if you need a larger countertop reserve than 1.5 gallons or if the 18.11″ x 7.48″ size will crowd your sink area.
What These Specifications Let You Do
Filtration Specs for Bad-Tasting Tap Water
Does the K8675 work with tap water that tastes bad but still has chlorine and sediment in it? Yes, because it is certified to NSF/ANSI 42 and 372, and it reduces 99.99% of chlorine, heavy metals, sediment, scale, and odor. That combination targets the taste and smell problems that usually drive a gravity water filter purchase.
The 6,000-gallon filter life gives you a long service window before replacement, which matters more than a big capacity when your main goal is cleaner-tasting water. The surprising part is that it does not reduce TDS, so it can improve chlorine-driven taste and odor without changing the dissolved-mineral reading that some buyers expect a filter to lower.
304 Stainless Steel Build and Leak-Proof Sealing
Purewell K8675 uses 304 stainless steel, and that material choice suits a countertop gravity filter that needs a rigid body and a stainless steel spigot. Leak-proof sealing is the other important build detail here, because poor chamber fit is a common failure mode in this category and can send unfiltered water into the lower chamber.
The included faucet and stand make the K8675 easier to place on a counter without extra parts, while the 18.11″ x 7.48″ footprint keeps the shape compact enough for a small setup. If you want a gravity filter that stays simple to assemble and move, those included parts matter more than decorative extras.
Capacity for Small Households
The K8675 holds 1.5 gallons, so it suits a 1- to 4-person household that wants a small batch on hand rather than a large reserve. That size helps if you want a gravity filter for light daily use, but it will not suit a counter where you need enough water for a full day without frequent refills.
For a small apartment counter, the 1.5-gallon capacity is the limiting factor, not the filtration standard. A family dinner, a weekend outage, or a high-drinking household needs more stored water than this model states, so you should treat it as a compact option rather than a low-refill one.
Which Jobs the K8675 Handles, Worked Out From Its Specs
The K8675 against 5 jobs buyers ask about, worked out from its listed capacity and a typical need for each job.
| Job | What it takes | K8675 |
|---|---|---|
| Fit a gravity filter on a small apartment counter without crowding the sink area | at least 2 to 3 gal | No – 1.5 gal |
| Hold enough water for a small kitchen without taking over the counter | at least 2 to 3 gal | No – 1.5 gal |
| Avoid refilling during a short camping trip for two people | 1.5 to 2.5 gal for 2 days, 70% usable | About 0.8 to 1.5 days – short of the 2 days the job takes |
| Keep a countertop filter from needing constant refills for a family dinner | 2 to 3 gal for 1 evening, 80% usable | Less than one evening – short of the 1 evening the job takes |
| Keep a filter useful for a household that drinks a lot of water every day | 3 to 4 gal for 1 day, 85% usable | Less than one day – short of the 1 day the job takes |
You might also consider evaluating the Purewell K8627 capacity to see how its larger reservoir compares.
The K8675 Against Similar Gravity Water Filters
K8675 gives you 1.5 gallons in a 304 stainless steel body, and that smaller capacity is its clearest trade-off against the 2.25-gallon models in this comparison. It also includes two black carbon filters rated for 6,000 gallons, plus NSF/ANSI 42 and 372 certification.
- Against US Water Filters SSGR2.25-CB-PF, the capacity is the sharper difference: 1.5 gallons here versus 2.25 gallons there. If you want a larger batch between refills, the competitor has the edge.
- Against KST-XYB101 1G Gravity-fed Water Filter, K8675 gives you a larger reservoir, with 1.5 gallons instead of 1 gallon. K8675 also states stainless steel construction, while the KST listing calls out 18/8 stainless steel and a transparent water level window.
- Against FACHIOO 2.25G Stainless Steel 304, the comparison again turns on capacity: 1.5 gallons versus 2.25 gallons. FACHIOO is the better pick if you want fewer refills for the same countertop use.
- Against Purewell Gravity Water Filter System, K8675 is the higher-priced option at around $118.99 versus $109. The cheaper model is the better buy if price matters more than the larger 1.5-gallon tank.
- Against Gravity Fed Water Filter System, the same price gap applies: around $118.99 here and $109 there. The competitor wins on cost, while K8675 is the one that states a 6,000-gallon filter life.
- On buyer ratings, K8675 ranks second highest in this set with a 4.2 average from 164 ratings. That places it ahead of the other 4.2-rated listings only because the comparison set includes a higher-rated rival.
If you want the bigger-capacity pick, choose FACHIOO 2.25G Stainless Steel 304 or US Water Filters SSGR2.25-CB-PF instead. If you care more about a stated 6,000-gallon filter life than tank size, K8675 is the one here that spells that out.
What the deciding spec costs here: Measured as price per unit of capacity, the reviewed product works out to $79.33 against a $73.11 median across the 18 other screened products that state the spec, and 9 of them deliver more of it per dollar. The cheapest screened product that beats its 1.5 gallons is the CO-Z UNSPECIFIED at $108.98 with 2.25 Gallons, which is $10.01 less than this one for more of the spec that decides this category.

Setting Up This Gravity Water Filter, and What Support Covers
Getting the K8675 ready for first use
You need a flat counter space that can hold the 18.11″ x 7.48″ footprint and support a 1.5-gallon stainless steel gravity filter.
- Unpack the K8675 and set out the 304 stainless steel chambers, the stand, and the faucet.
- Install the two black carbon filters in the positions shown for this 6,000-gallon setup.
- Fit the stainless steel spigot and tighten the sealing points so the leak-proof sealing can do its job.
- Fill the upper chamber with water and let it pass through the NSF/ANSI 42 & 372 filtration path before first use.
Warranty and support: what to verify before your return window closes
Cover varies by seller and country.
- Confirm the return window for the 1.5-gallon K8675, because a small-capacity gravity filter is easy to size wrong for your counter and household needs.
- Confirm whether replacement filter elements are available, because the listed 6,000-gallon life means the filters are consumables.
- Confirm that any spigot gasket matches the stainless steel outlet, because the faucet and sealing points are part of the leak control.
- Confirm whether a priming washer is needed for the installed filter elements, because some setups need that part before water flows correctly.
On the day it arrives, inspect the faucet, stand, and filter seats before you fill it.
K8675 Buying Questions Answered
Does the K8675 reduce TDS?
No, the K8675 does not reduce TDS. The listing says “does not reduce TDS,” so a TDS meter may still show the same reading after filtration.
Is the K8675 worth it once I factor in replacement filters and upkeep?
That depends on whether you want a 1.5-gallon stainless steel gravity filter with two black carbon filters and NSF/ANSI 42 and 372 certification. The $118.99 price is the upfront cost, and the filter life is listed at 6,000 gallons, but the replacement-filter price is not stated here.
Do you need a countertop filter for a small kitchen? The K8675 holds 1.5 gallons, so it suits lighter daily use better than larger batch needs.
The 4.2 average from 164 buyer ratings gives context, but the capacity still matters more than the score for your day-to-day use. If you want fewer refills, the stated 1.5-gallon volume is the number to focus on.
Is the K8675 Right for You?
The K8675 suits 6 kinds of buyer and is the wrong choice for 5 jobs, listed below with the reason for each.
Who this countertop gravity filter is for, and what it does well
Who the K8675 suits
- Small households of 1 to 4 people — 1.5-gallon capacity is enough for daily drinking water without taking up much counter space
- Apartment renters with limited kitchen space — 18.11″ x 7.48″ dimensions and gravity-fed design fit on a counter without plumbing
- People avoiding chlorine taste and odor in tap water — two black carbon filters and 99.99% chlorine reduction target taste and smell issues
- Households with older plumbing concerns — NSF/ANSI 42 & 372 certification plus heavy metal and sediment reduction suit basic point-of-use filtration
- Homeowners who want a low-maintenance water filter — 6,000-gallon filter life means fewer cartridge changes over time
- People who prefer stainless steel kitchen gear — 304 stainless steel construction is durable, corrosion resistant, and rust resistant
What this Gravity Water Filter handles well
- Filtering drinking water for a small family — 1.5-gallon capacity and 1 to 4 person user capacity
- Reducing chlorine taste and odor in tap water — two black carbon filters and 99.99% chlorine reduction
- Basic countertop water filtration without plumbing — gravity-fed format and compact 18.11″ x 7.48″ size
- Improving water clarity for everyday use — sediment reduction and leak-proof sealing
- Long-term household water filtering — 6,000-gallon filter life
- Kitchen use in humid or wet environments — 304 stainless steel material and corrosion/rust resistance
What this Gravity Water Filter is the wrong choice for
- Removing dissolved minerals from hard water — does not reduce TDS
- Supplying water for large households or offices — 1.5-gallon capacity and 1 to 4 person user capacity
- Replacing a plumbed under-sink filtration system — gravity filter design with no plumbing connection
- Making ultra-low-mineral water for espresso or lab-style brewing — does not reduce TDS
- High-volume water dispensing for parties or break rooms — small 1.5-gallon reservoir limits batch size
What to budget alongside this gravity filter, and what to skip
Accessories worth buying with the K8675
- Replacement carbon filters — the unit uses two black carbon filters and they will need eventual replacement
- Clean water storage container — gravity filtration needs a vessel to collect the filtered water
- Faucet-safe filling pitcher or jug — the 1.5-gallon reservoir has to be filled manually
- Countertop stand or stable base — the 18.11″ x 7.48″ body needs a secure place to sit
- Cleaning cloth or non-abrasive stainless steel cleaner — 304 stainless steel surfaces need routine wiping to stay clean
Accessories you can skip buying for this countertop gravity filter
- Plumbing installation kit — this is a gravity filter, so it does not need a water line hookup
- TDS meter — the filter does not reduce TDS, so a meter will not change the water chemistry outcome
- Large replacement tank — the 1.5-gallon capacity is already built in and not expandable by a separate tank
- Heavy-duty descaling system — the filter reduces scale, but it is not a full softener or descaler

Final Verdict on the K8675
You should choose the K8675 if you need a 1.5-gallon gravity water filter for one to four people and want stainless steel construction, NSF/ANSI 42 and 372 certification, and a stainless steel spigot. At around $118.99, it also includes two black carbon filters, a faucet, and a stand.
The strongest figure here is the 1.5-gallon capacity. That size keeps the unit compact, but it also means less ready water than larger countertop gravity filters, so frequent refills are part of the trade-off.
Skip it if: you need a countertop gravity filter for a small apartment counter with fewer refills, or you want enough stored water for a full day of heavy household use.
