We read the Waterdrop whole house specs for you
Waterdrop makes two three-stage whole house filters. The FG model reduces iron and manganese, and it works on well water. The PG model costs less and is built for city water. Both pass 15 gallons a minute. Both install with no plumber. Waterdrop does not publish a warranty term for either model, so neither gets a score badge here.
The FG model is $419.99. The PG model is $369.99. Both prices are in US dollars.
Here is the short version
- The FG model reduces iron and manganese. Most city-water filters do not.
- The PG model does not reduce iron or manganese. It is a city-water filter, not a well filter.
- Both models pass 15 gallons a minute, which suits a small to mid-size home.

Here are the specs Waterdrop publishes
We show the raw number next to each one Waterdrop publishes. Where a number is missing, we skip that row.
Flow rate is how much water it can pass at once. Too low and your shower fades when the washing machine fills.
Each model holds three filters. Waterdrop rates each filter for 100,000 gallons of water.
Waterdrop does not publish a yearly filter cost for these models. Each filter is rated for 100,000 gallons instead, which is the number we show above.
We do not take these units apart and we do not run them in a lab. We read what Waterdrop publishes, and we show you the figures.

Who should buy the FG model?
- Buy the FG model if your well water has iron or manganese in it. It is the one of the two built for that.
- Buy the FG model if your water stains sinks or tastes of metal. Iron and manganese cause both.
- Buy the FG model if you want to install it yourself. Waterdrop says no plumber is needed.
Who should buy the PG model?
- Buy the PG model if you are on city water and want to pay less. It costs $369.99.
- Buy the PG model to cut chlorine taste and smell. Waterdrop says it removes 97.7% of chlorine.
- Buy the PG model if you also want to take out sediment, rust and sand.
Who should skip both?
- Skip the PG model if your well has iron. It does not reduce iron or manganese.
- Skip both if hard water is your only problem. Neither one softens water.
- Skip both if your home needs more than 15 gallons a minute at once.
If none of these rows fit your house, buy something else. We would rather you bought the right unit somewhere than the wrong one through us.
