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.
