Culligan HF-360A

Culligan HF-360A Whole House Filtration System

  •    Price: $$
  •    Flow Rate: 1.5-6.5 gpm
  •    Filt. Capacity: 8k-16k gal
  •    NSF Cert.: 42
  •    Warranty: 5 Years

In this triple review we will examine the following whole home water filtration systems sold by Culligan:

  1. The HF-360A, a standard duty system with ¾” inlet and outlet connectors for moderate water flow suited for small to mid-sized homes.
  2. The HD-950A, a heavy duty system with 1″ ports for up to 4 times the capacity of standard filters making it ideal for the water treatment needs of large homes, farms, swimming pools and possibly spas.
  3. And the HF-150A, again, a standard ¾” whole house filter for residential use.

All three units help to protect your costly home appliances – think washing machine, dishwasher, hot water heater, faucets, showers and refrigerator – as well as your plumbing system from sediment and scale buildup.

In addition, they might also trap sand, rust, coarse and silt, and even eliminate chlorine and other tastes & odors. However, this depends on which filter cartridge you choose to use.

You should also be aware that some cartridges have lower flow rates so that they are only suited for single households or a maximum of 2 people living under the same roof.

The HF-360A and the HF-150A can work at a pressure range between 30 and 125 psi, whereas the maximum allowed water pressure for the HD-950A heavy duty system is 100 psi.

By the way, each of the three comes with a 5-year limited warranty for ease of mind.


What we like about the HF-360A is that it features a clear housing allowing you to check the state of the cartridge inside. This makes timely replacement a lot easier.

Also, the housing was tested and certified by the WQA against NSF/ANSI Standard 42 for structural integrity and material safety. Why is this important? Because you don’t want any contaminants such as microplastics to leach into your water.

The same goes for the HD-950A housing which, too, was tested and certified against NSF/ANSI Standard 42. Apart from a larger diameter, the main difference is that the housing is blue.

Blue is also the HF-150A. Certified by the WQA against Standard 42 for material safety? You bet!

Are you handy around the house? Then DIY-installing one of these whole home systems won’t be a problem. If you want to learn more, here are some basic instructions:

Location, Location, Location

First you should find the best place to install your new whole house filter.

Remember that it must be positioned after any water meter, pressure tank or booster pump.

There should also be enough room below the unit for the housing to be removed to allow for easy filter changes.


  1. Before you start with the actual setup, remember to close the main water valve.
  2. Open the nearest faucet to drain all remaining water.
  3. Apply Teflon tape (not included) to pipe thread of each adapter (not included) and start into inlet/outlet thread. Tighten firmly.
  4. Remove pipe section from main water line using a pipe cutter or hacksaw. Sand or file rough edges.
  5. Mount the system to the wall using provided bracket and screws.
  6. Connect inlet/outlet port to main water line.
  7. Place cartridge into housing making sure that it slips over the stand pipe at the bottom and into the stand pipe in the filter head. Tighten housing with wrench.
  8. Put bypass valve into filter mode.
  9. Slowly open the main water valve.
  10. Press the pressure relief button on top to release any trapped air.
  11. Check everything for leaks. Tighten connections if need be.
  12. Open the nearest faucet and flush for 5 minutes.
  13. Reset the filter life indicator by holding the reset button for 2 seconds until green light flashes.
  14. (If water pipes are used for grounding, make sure to add a jumper wire.)

The Package (Parts)

Culligan HF-360A:

  • Valve-in-head cap with clear housing
  • Housing wrench
  • P5 cartridge

Culligan HD-950A

  • Housing
  • Housing wrench

Culligan HF-150A

  • Housing

Please note: Both the HD-950A and the HF-150A do not include a filter cartridge!


There’s not much to be said about system maintenance.

The HF-360A has a built-in shut-off valve so that you can change filters easily and without having to close the feed water.

The unit is compatible with Culligan S1A, CW-MF, CW-F, P5 and P1 cartridges.

A pressure relief button makes filter replacements for the HD-950A at least somewhat easier. You won’t get around closing the water supply to your entire home, though, unless you have installed a bypass.

Compatible filters: R50-BBSA, CP5-BBS, RFC-BBSA and possibly more. The latter was tested at NSF International for the reduction of chlorine taste and odor (90.3%) to a capacity of 10,000 gallons.

The HF-150A has neither a built-in bypass nor a button to release pressure. Compatibility: S1A, CW-F, P5, P1 and possibly others.

Because there are so many different configurations that you can choose from, annual replacement costs vary from setup to setup. Generally speaking, we can say that Culligan filters are affordable and widely available online and offline.

A common issue is leaking, mainly at the inlet and outlet ports (remember to wrap the adapter with lots of Teflon tape).

Our Verdict

Bottom line: Most users are happy with their product which does exactly what it’s supposed to do and that is remove sediment and scale from all the water entering their homes.

A whole house system for basic water filtration needs to protect your plumbing and water-using appliances. Great if you are on a budget. 4 stars!
