The type layer, priced apart
| Frame | Type line, as published | 2026 band, installed |
|---|---|---|
| Frame B | drum installation | $200-$750 |
| Frame B | flow-through installation | $200-$950 |
| Frame B | steam installation | $500-$2,200 |
| Frame A | any type, project whole | $392-$768 |
Every figure here is a published line inside its own frame, never averaged into one band. Type is the first attribute Frame B names on this layer; Frame A names no type split at all. The project whole prices on the whole-home humidifier hub; the breakdown layer on the breakdown guide.
Frame B type lines, as reported
| Type line, as published | Unit alone | 2026 band, installed |
|---|---|---|
| Drum | $100-$300 | $200-$750 |
| Flow-through | $100-$500 | $200-$950 |
| Steam | $300-$1,300 | $500-$2,200 |
Frame B's type table prints each type twice: the unit alone and the installed total. Drum prints lowest on both readings, flow-through sits in the middle, and steam carries the highest unit line and the highest installed total of the three. No type total is added into a new total on this page.
Frame A reading, as reported
| Frame A line, as published | Reading | 2026 band |
|---|---|---|
| Small budget models, low end of the range | per project | $175 |
| Typical project, across types | per project | $392-$768 |
| High-end furnace-mounted units, top of the range | per project | $1,350 |
| By-type split | per type | no priced line printed |
Frame A ties the ends of its range to unit class -- small budget models at the low end, high-end furnace-mounted units at the top -- without printing a total for any single type. Its typical band is read across types, as published, and no Frame A figure here is split into a type line it never printed.
Forms named inside the type lines, as reported
| Form, as published | Where it prints | 2026 band |
|---|---|---|
| Bypass form | drum and flow-through lines, Frame B | no separate priced line printed |
| Fan-powered form | flow-through line, Frame B | no separate priced line printed |
| Steam, standing apart | own type line, Frame B | $500-$2,200 installed |
Bypass and fan-powered print as form names inside the drum and flow-through lines, counted in those types' totals on Frame B and named in no split on Frame A. Steam prints as its own type line on both readings of the layer. The capacity reading crossed with home size sits on the breakdown guide, as its own priced lines.
Reading a by-type quote, by frame
A type line answers the type question: drum, flow-through, or steam. A quote names its type in its first line and its frame beside it, and its installed total apart from any unit-alone reading.
- Type named beside every band
- Installed totals read apart from unit-alone lines
- Each frame's type reading read on its own frame only

Are bypass and fan-powered priced as separate types, as reported?
