Home Master HMF3SdgFeC Whole House Water Filter – Key Features

Let’s start this review by examining the filtration process in more detail.

The Home Master HMF3SdgFeC uses 3 filter stages:

  1. A multi-gradient density sediment filter traps rust, sand, silt and other particles down to a size of 1 micron (nominal). Multi-gradient density sediment filter? Yes, it means the filter has multiple layers that remove particles of different sizes. The surface layer stops everything measuring 25 microns or larger. Then come 2 inner layers (10 and 5-micron) and lastly a 1-micron core layer. For one, this will make your water crystal clear and even take care of some bacteria and cysts. In addition, multi-gradient density filters have triple the dirt holding capacity of similar sized cartridges, says Home Master.
  2. The second stage uses a specialized iron filter. Reduction capabilities: 3 parts per million of both ferrous (clear-water iron) and ferric (red-water iron) a.k.a. rust. The filter is also effective against manganese and sulfur, but they’ll both lower the life of the filter cartridge at up to 2-6 times the rate of iron. Ideally, manganese is below 1 ppm and hydrogen sulfide is nonexistent. What about iron bacteria? If there’s iron bacteria in your water additional pre-treatment will be required.
  3. Coconut shell granular activated carbon (20 micron nominal) gives your water a final polish – think improved taste and odor. Apart from chlorine, the carbon adsorbs chemicals, VOCs, and some other stuff.

Although the filtration process is quite complex, flow rates are as high as 15 gallons per minute which is plenty of water and enough for homes with 4+ bathrooms.

Recommended operating conditions:

  • pH: >7.0
  • Feed water pressure: 20 – 90 psi

Please note: This whole house water filter should not be used with water that is microbiologically unsafe or of unknown quality without further treatment.

With a little plumbing experience this system is not hard to install at all. You should consider adding a bypass, though, since the unit doesn’t have one built in.


The Package (Parts)

  • HMF3SdgFeC system module incl. mounting hardware
  • 1x CFdgd2501-20BB multi-gradient density sediment filter cartridge
  • 1x Cfrffe-20BB iron filter cartridge
  • 1x CFrfgac20-20BB granular activated carbon filter cartridge
  • Filter housings with O-rings
  • Silicone grease
  • Housing wrench
  • Instruction book
  • Warranty card


The good news is, there’s not much servicing required which is convenient. Also, the optional pressure gauges will tell you at a glance if it’s time for a new filter. And while whole house cartridge water filters are way more affordable upfront compared to systems using one large media tank that often requires backwashing, replacements filters for the HMF3SdgFeC are not exactly cheap.

Depending on your water usage and quality,

  • the sediment filter requires annual or biannual replacement. Cost per piece: ~$36.00
  • the iron filter lasts around 100 days to 1 year for a family of 3 (4). Cost per piece: ~$125.00
  • the activated carbon filter lasts roughly 100,000 gallons. Cost per piece: ~$100.00

In other words, if frequent replacements are required the cost start to add up quickly. One way around this issue could be to purchase aftermarket filters. Any standard-sized cartridge (20″ x 4.5″) will work. But make sure to not compromise on quality!

HMF3SdgFeC Cons

  • No built-in bypass
