I purchased a whole house filter set and installed it, but then my flow rate dropped.

Please follow the steps below to install whole house filters correctly.

Step 1:

First, make sure that you install the filters in the correct flow direction (i.e., if your system flow is Right to Left, make sure to install the Sediment filter first, GAC or Iron Manganese second, and CTO last). Installing the filter in the opposite direction will force the water to flow from the center of the Sediment filter to the outside, causing a pressure drop and clogging your filter.

Step 2:

Second, make sure to install the GAC and Iron filter from the correct end (Center open hole on top). If you install these filters upside down, they will restrict flow, potentially damaging the filter body.

Step 3:

Third, when you install any GAC, UDF, or T33-type filters in the first stage, the filter's inlet woven surface flow will be restricted, and this woven/mesh can get clogged within a couple of hours or days, causing a significant pressure drop.
