WHC+ Whole House Premium 0.5 Micron Carbon Block Filter Package

The WHC+ is our best whole house filter package. It features filtration of sediments, particulates, and other contaminants down to a level of 0.5 microns (nominal) as well as extraordinary chlorine and VOC (volatile organic compounds including most pesticides) reduction capacity.

The WHC+ whole house filter package features multi-stage filtration for a wide range of common contaminants. This system features Pentek's popular 100% pure polypropylene dual-gradient sediment filter to remove fine sediment particles down to a level of 5 microns, thereby protecting the more expensive carbon filter from sediment loading. The polypropylene media is highly resistant to bacteria, making this an excellent choice for well water treatment applications.

The sediment filter is followed by Pentek's CBC-20BB 0.5 micron carbon block filter which is highly effective at reducing unwanted taste, odor, chlorine, a wide range of volatile organic chemicals (VOC's) and pesticides. The WHC+ has exceptionally high chlorine reduction capacity - 90% reduction over a filter life of 150,000 gallons at a flow rate of 4 gallons per minute (567,800 L at a flow rate of 15 LPM), almost 4 times more chlorine reduction capacity than standard 5 micron whole house carbon block and GAC filters. With its nominal 0.5 micron rating, this filter also effectively removes 99.9% of cryptosporidium and giardia cysts, as well as extremely fine sediment particles, making the WHC+ a popular choice for a wide range of residential, food service, commercial, and industrial water treatment applications. This system is also a popular choice for well water owners requiring pre-filtration down to a level of less than 1 micron for certain UV sterilizer applications, especially where elevated levels of cryptosporidium and giardia, or high levels of organic contaminants are present (organic contaminants can absorb UV light). A water temperature of less than 85F is highly recommended for VOC and pesticide reduction.

Note: Due to its extremely high filtration effectiveness, this filter is more restrictive to water flow and accordingly has a higher pressure reduction than standard large diameter carbon block and GAC filters. To try to compensate for this as much as possible, we utilize very large 4.5 inch diameter x 20" filters in our WHC+ whole house systems. By increasing surface area, these large format filters help prevent premature clogging and maximize surface area to reduce pressure loss.

Applications & Suitability:

The WHC+ is designed for consumers seeking the highest rates of contaminant reduction possible in a whole house cartridge filter. The WHC+ is an excellent all-round whole house filtration system for the removal of ultra fine sediments, particulates, cryptosporidium and giardia cysts, chlorine, bad tastes and odors, VOCs and pesticides. It features the highest chlorine reduction capacity of all of our whole house filter systems (by far). It is a popular choice for a wide range of residential, food service, commercial, and industrial water treatment applications. This system is also a popular choice for well water owners requiring pre-filtration down to a level of less than 1 micron for certain UV sterilizer applications, especially where elevated levels of cryptosporidium and giardia, or high levels of organic contaminants are present (organic contaminants can absorb UV light). The WHC+ is an excellent choice for well water, lake water, stream water, and municipal (city) water treatment applications. For best results, we recommend a maximum flow rate of 4 gallons per minute (suitable for typical residential whole house applications) and a water temperature of less than 85F, especially when VOC and pesticide reduction is a primary objective.
