FAQ
Curious about how the countertop water filter works? Our FAQ section
covers everything from filter lifespan to installation tips for clean, pure water every day.
Does the water filter leak where the
upper and lower chambers fit together?
When the lower chamber is full and there is water in
the upper chamber, water might leak from where the two chambers together. To prevent overflow, it is
recommended to empty the lower chamber completely prior to refilling the upper chamber.
What substances does the water filter
system reduce?
The filter media adopted in the King Tank portable
water filter is natural coconut activated carbon, which effectively reduces chlorine and improves
taste. You can get up to 98.95% of chlorine reduction. The filter can effectively reduce heavy
metals, sediment, rust, soil, and other impurities while improving the odor and taste. However, if
there is a need for TDS reduction, feel free to check Waterdrop RO water purifiers.
Can water filter remove the peculiar
smell of water?
Yes. The filter media adopted in the King Tank
stainless steel water filter is natural coconut activated carbon, which effectively reduces chlorine
and improves taste.
How often to replace the water filter?
The two carbon filters can effectively filter up to
6,000 gallons of water. You need to replace the filter once it achieves the maximum filter capacity.
The actual replacement time might vary according to the local water quality.
How do I know the level of water
filtration?
The complimentary metallic water level spigot would be
a great solution. It allows you to determine how much purified water remains without removing the
lid or remove the upper chamber to see the remaining water in the lower chamber. You can assess the
water level accurately with the red floating ball in the sight glass spigot.
Which scenarios does this gravity
water filter apply to?
This gravity-fed water purification system can be
placed in multiple scenarios ensuring you get pure water indoors or outdoors including RV,
backyard and comping. It’s the essential tool for emergency preparedness.
What is the model number of the
replacement water filters, and where can I find them?
For the white fluoride filter, the model number is
PF-2-C, while for the black carbon filter, the filter number is BB9-2. You can find them by
searching for the model numbers.
Is there any reason I have a slow
initial flow rate?
This may be due to the wrong installation of the
carbon filter. You can check this by removing the filters from the system and submerging them
into a tall container containing clean water, such as the lower chamber of your filtration
system. The filters either sink or float. Floating means the micropores contain trapped air,
while sinking signifies complete saturation. Transfer the filter cartridges into clean water and
allow them to sink to the bottom before reinstalling them into the system. If you continue to
experience a slow flow rate after this, reach out to our Customer Service.
Is the King Tank stainless steel
water filter complicated to install?
King Tank water filter system can be easily set up
and install all by yourself without prior plumbing experience. The water filter system requires
no electricity to work. All you have to do is install and enjoy clean and pure drinking water at
all times, even when there is a flood or snowstorm.
Why is there water in the upper
chamber after filtration?
Having one or two inches of water in the upper
chamber post-filtration is expected. Since you have gravity filters, the water level in the
upper chamber drops and leads to a slower filtering process. This is normal, considering there
is less water pressure available to push water through the filter elements.
The TDS levels did not drop after
filtration. Is this normal?
This system is not designed to primarily reduce
TDS, which is the total amount of mobile charged ions in water. TDS include metals, salts, and
minerals, all dissolved in a specific volume of water. Being a gravity-fed water filter system,
the filtration process does not eliminate the beneficial materials. It only reduces the harmful
materials. You can get a Waterdrop RO water filtration system if you want a filter system that
does both.
I got this about a month ago and so far I am loving it. I have used several times and it grinds freshly milled flour effortlessly. Wish I would have bought one sooner
This mixer is a power house. NutriMill is an incredible company with excellent customer service! We also have the harvest grain mill! I look forward to buying more products from NutriMill as continue to bake more for our family.

I’d been eyeing the party barge for a few months, and finally decided to take the plunge because we were hosting a 50+ person brunch. This cooler was the star of the show! Held all the prosecco & juices for the mimosa bar plus the mixers/alcohol for the signature cocktail. Perfection! Everyone was talking about it. Clean up was easy - simply carried it outside to empty with the other coolers. Probably will purchase the smaller size in the future.
Going from a manual grain mill to this nutril mill impact grain mill was wonderful. While a little louder than thought and perhaps a little slower than expected, it was way better than grinding manually. VERY Happy I found this grain mill.
When I first got my mill, I had a bag of corn meal on my shelf that was sitting, unused because it was too coarse. I put it through the mill on the finest setting and it milled it quickly and perfectly. That night, I cooked cornbread with the cornmeal that I had refused to use because it was so coarse. That is only the beginning of my journey. I have milled cornbread, wheat and spelt, all without problems. Everything comes out perfectly.
