The WH3 whole house filter package features dual stage filtration for a wide range of common contaminants that affect the clarity, taste, and odor of residential water. This system features Hydronix's unique multi-depth poly sediment filter which removes dirt, sediment, rust particles, and other particulates down to a level of 10 microns thereby protecting the carbon filter and preserving its capacity. This filter uses the entire depth of its media by trapping the largest sediment particles on the outside of the filter, then gradually stepping down the size of particles it will reject as the water moves closer to the core of the filter. The outer layer is rated at 75 microns. The subsequent layers are rated at 50 microns, 25 microns, and finally 10 microns. The result is longer filter life and higher flow rates (less pressure drop). The polypropylene media is highly resistant to bacteria, making this an excellent choice for well, lake, and stream water treatment applications, in addition to city water.

This filter is followed by Pentek's GAC Series granular activated carbon filter which allows water to enter at one end and pass through the entire length of the carbon bed thereby maximizing contact time and contaminant removal before exiting the other end (upflow design). Accordingly, somewhat higher contaminant removal rates can generally be achieved as compared to most radial flow GAC or carbon block filters, although the filter life will be a bit shorter. A 20 micron built-in post-filter helps remove carbon fines and other suspended particulates. An internal expansion pad reduces channeling and bypass. The WH3 is a very popular choice for general chlorine reduction. It is also commonly used to remove chlorine disinfection by-products (THM's), and a wide range of organic and volatile organic compounds (VOC's) that affect water clarity, taste, and odor. Minimum chlorine reduction of 90% over a filter life of 12,400 gallons at a flow rate of 2 GPM (47,000 L @ 7.6 LPM).

Applications & Suitability:

The WH3 is a very popular general purpose whole house water filter package. It is well suited to sediment and particulate removal as well as the reduction of chlorine, chlorine disinfection bi-products like trihalomethanes (THM's), a wide range of volatile organic compounds, and other contaminants responsible for bad tastes and odors. The WH3 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 about 3-4 gallons per minute, which is sufficient for an average residential application (for higher flow rates, see our WH3-HF High Flow Series Carbon Block Filter).

Note: Some municipalities disinfect their water with chloramine instead of chlorine. We recommend that you confirm which disinfectant your city uses to treat your water supply so you can ensure that you choose the best filter for your needs. If your water supply is treated with chloramine, we highly recommend that you consider the WH Chloramine filter which uses a special catalytic carbon to enhance chloramine removal.


Why choose the WH3 GAC Carbon Filter Package?

  • large carbon bed and upflow design maximizes contact time between contaminants and media to enhance contaminant removal rates
  • less risk of channeling and bypass as compared to competitor's granular activated carbon (GAC) filters
  • we use only the highest quality heavy duty filter housings with large diameter inlet and outlet for less pressure drop and better flow dynamics
  • housings and filters are NSF Certified (Standard 42 for material requirements)
  • we use standard filter sizes so you will always be able to obtain replacement filters for your system
  • many competitors use small 2.5" x 10" filters in their whole house filter systems, resulting in poor water pressure, short filter life, and less than optimal flow characteristics - we use filters with much greater surface area to maximize contaminant removal, improve water pressure and flow characteristics, and extend filter life so you have less maintenance to do!
  • sturdy powder-coated steel mounting bracket and spanner wrench included
  • great pricing on system packages are replacement filters - guaranteed best prices in USA and Canada on all replacement filters purchased by the case!

Included in package:

  • two (2) heavy-duty Pentek Big Blue 10" filter housings (1" NPT) w/ pressure relief buttons
  • one (1) powder-coated mounting bracket and related screws
  • one (1) Hydronix SDC-45-1010 multi-gradient 10 micron sediment filter cartridge
  • one (1) Pentek GAC-BB granular activated carbon cartridge filter
  • one (1) spanner wrench
  • one (1) 1" brass housing coupler used to join the 2 filter housings
  • one (1) roll of Teflon tape
