Size readings, priced apart by frame
| Pool size row | Frame A installed reading | Frame B reading |
|---|---|---|
| Up to 10,000 gallons row | $500-$900 | inside the $250-$1,700 average range |
| 10,000-20,000 gallons row | $900-$1,500 | inside the $250-$1,700 average range |
| 20,000-30,000 gallons row | $1,200-$2,000 | inside the $250-$1,700 average range |
| Over 30,000 gallons row | $1,800-$2,500 | inside 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.
Type bands behind the size rows, printed once
| Frame A type line, as printed | Unit | Installed |
|---|---|---|
| Sand row | $250-$600 | $500-$1,200 |
| 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.
Frame B readings behind the size rows, printed once
| Frame B line, as reported | 2026 reading |
|---|---|

| Average range row | $250-$1,700 |
| Minimum row | $80 |
| Maximum row | $2,500 |
| Sand unit row | $200-$800 |
| Cartridge unit row | $200-$1,000 |
| DE unit row | $500-$1,100 |
| Glass unit row | $500-$1,500 |

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.

Frequently asked questions
What does pool filter replacement cost by pool size, as reported?
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.
