Waterdrop WHF21-PG for Whole House Sediment Filtration

The Waterdrop WHF21-PG is a two stage whole house filtration system with 5 micron filtration for point of entry treatment. Its compact dual housing design uses the WD-WF10PG replacement filter set.

Best suited for: Homes that need a compact point of entry sediment and carbon filtration arrangement before water reaches fixtures and appliances.

Why choose this system

Choose the WHF21-PG when a two stage 10 inch format fits the installation space and service needs better than a larger three stage whole house system.

How this benefits your home

  • Cleaner water reaches every fixture: Point of entry filtration treats the household supply before it branches to faucets, showers, and appliances.
  • Helps reduce sediment related buildup: Five micron filtration limits particulate material reaching plumbing fixtures and water using equipment.
  • Supports longer equipment service: Reducing sediment load can help protect valves, aerators, appliances, and downstream treatment systems from premature fouling.
  • Maintenance is easier to plan: Pressure gauges provide a visible way to monitor system conditions and recognize when service may be needed.
  • Keeps utility space organized: The compact wall mounted dual housing layout provides whole house treatment without a large floor standing tank.
  • Replace filters instead of equipment: The WD-WF10PG cartridge set renews the filtration stages while preserving the installed housings.

Frequently asked questions

What does the WHF21-PG treat?

The two stage system uses 5 micron filtration to help reduce sediment and improve water quality before water reaches household fixtures and connected equipment.

Where is the system installed?

It installs on the main water line at the point of entry so incoming water is treated before distribution through the home.

Does this system soften hard water?

No. It is a whole house filtration system, not a salt based ion exchange softener. Pairing needs depend on your source water concerns.

What should be planned before installation?

Confirm available wall space, pipe size, service clearance, shutoff access, and a suitable installation location. The pressure gauges help monitor the two stages.

Does it require electricity?

The filtration housings do not require electricity for normal water flow.
