Buy Online the  4-stage reverse osmosis TankPro-PRO 3.2 Replacement filters.
 
TankPro under-sink reverse osmosis water systems - include five filters that must be replaced periodically.  
 
The different Tankpro filters represent the various stages that the water goes through while being purified.   
 
Generally - Pre-Filters and Post-Filters in All TankPro water systems can last around 12 months between changes.
 
Only the Organic RO membranes can last as long as five years.
 
 Stage 1-
The sediment filter is the first filter installed in the TankPro- PRO 3.2 Reverse Osmosis water filter system.
The primary function of a sediment filter is to remove large and fine particles from drinking water, such as sand, dirt, silt, and rust particles. Removal of such particles allows for a better performance of all the following filters, such as Carbon Block or GAC filters.
Micron rating: 5 Micron.
Dimensions: 9.75" x 2.5"
Lifetime: Replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF Standards and Regulations. The filter will fit any Residential Reverse Osmosis Unit with standard 10” filter housing.
 
Stage 2-
Original Organic Activated Carbon GAC filters are well-known for their highly efficient reduction of chlorine taste and odor
taste and odors of many organic chemicals and volatile organic compounds.
All GAC filters are made with Organic, high-quality coconut shell carbon.
Micron rating: 5 Micron. Dimensions: 9.75" x 2.5"
Dimensions: 9.75" x 2.5"
Lifetime: Replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF Standards and Regulations. The filter will fit any Residential Reverse Osmosis Unit with standard 10” filter housing.
 
 
Stage 3-

Organic Original Activated Carbon Block Filters are made of fine coconut shell carbon 
to remove odors and tastes of many organic compounds, chlorine especially. Though, because these filters are made of packed carbon (forming a cylinder block), they offer a much finer filtration of suspended particles and dirt.
Micron rating: 5 Micron. Dimensions: 9.75" x 2.5"
Dimensions: 9.75" x 2.5"
Lifetime: Replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF Standards and Regulations. The filter will fit any Residential Reverse Osmosis Unit with standard 10” filter housing.
 
Stage 4-
Original Organic Inline Carbon Filter For Tankpro is also known as a polishing filter because they are usually the last stage of any standard Reverse Osmosis circuit. Made of high-quality coconut shell carbon, they stabilize the water-tasting qualities and remove any traces of nasty tastes and odors.
Dimensions: 10 " x 2"
Lifetime: Replace ones in 1- 2 years.
