Pool Filter Replacement Cost by Pool Size Guide

The replacement priced by pool size: gallonage bands priced apart inside each frame.

Orange County, CA · Updated 2026 · Costs shown as ranges — your quote will vary by firm and scope

Reading this guide: every figure below is a range from published 2026 pricing data — not a quote. Two frames are named apart and never blended: Frame A (the Angi frame, installed) and Frame B (the HomeGuide frame, replacement). The frames count the same repair visit differently, and that difference is named on every page. Always get 3 written quotes.

Size readings, priced apart by frame

Up to 10,000 gallons row$500-$900inside the $250-$1,700 average range
10,000-20,000 gallons row$900-$1,500inside the $250-$1,700 average range

Over 30,000 gallons row$1,800-$2,500inside the $250-$1,700 average range

Each reading is one frame counting of one size band, never blended across sizes or frames. Frame B prints no band by gallonage: its rows stand as printed, never split by size.

Cartridge row$300-$900$700-$1,600
DE row$400-$1,200$1,200-$2,500

The type bands are printed once here, shared by the size rows -- the same filter type is never carried across the size line as a second line. Each size band reads against this one set of lines.

The Frame B lines stand once, as on the hub, with the cartridge counted three ways across the frames. The frames count the same job on different bases -- installed totals by size and type in Frame A (a cartridge system at $700-$1,600 installed) against unit-price replacement ranges in Frame B (a cartridge unit at $200-$1,000, a national average at $950). The cartridge line is counted three ways across the frames -- $700-$1,600 installed in Frame A, $200-$1,000 as a unit in Frame B, and $500-$1,200 installed in the standing equipment hub single line -- named as frame differences on every page, never averaged.

The neighbours named apart

Media readings price apart on the companion guide. Named apart, never a row here: the pool pump clusters (the pump, not the filter), the pool-equipment replacement hub (a whole-equipment ticket, its own field -- this cluster carries no whole-equipment guide of its own), the whole-house water filter pair, pool cleaning service pricing, and whole-pool renovation tickets, each in its own lane.

Frame A prices up to 10,000 gallons at $500 to $900, 10,000 to 20,000 at $900 to $1,500, 20,000 to 30,000 at $1,200 to $2,000, and over 30,000 at $1,800 to $2,500 installed. Frame B prints no gallonage band.

What does the smallest size row print at, as reported?

Frame A prints the up to 10,000 gallon band at $500 to $900 installed. Frame B prints the same job inside its $250 to $1,700 average range, beside a national average at $950.

What does the largest size row print at, as reported?

Frame A prints the over 30,000 gallon band at $1,800 to $2,500 installed, its widest band. Frame B prints a maximum at $2,500 across its whole replacement read.

Why is each filter type printed only once on this page?

The type lines belong to the replacement, not to a size: the cartridge at $700 to $1,600 installed stands once, shared by the size rows, so no type is carried across the size line twice.

Is a size row the same purchase as a whole-equipment ticket on the standing hub?

No. The pool-equipment replacement hub is its own field, named apart here, and this cluster carries no whole-equipment guide of its own. Each size row prices one filter replacement alone.
