Place a portable air cleaner sized to the room, a public library reading room, Notrees, TX.

This library reading room sits a few blocks from active oilfield lease roads and tank batteries, and fine dust tracks in on wind days with nothing in the room to touch it -- there is no central air system reaching this wing at all, only windows and a single door. A portable HEPA unit sized to the room's floor area, placed and run today, changes the air in this specific room with no ductwork and no wiring.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

baseline PM2.5 reading + unit sizing record + placement photo + post-run PM2.5 reading + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. 1. Measure the room's floor area and ceiling height, and confirm the chosen unit's Clean Air Delivery Rate (CADR) meets EPA's room-size guidance (CADR at least two-thirds of the room's floor area in square feet).
2. 2. Take a baseline PM2.5 reading with a handheld particulate meter at the room's breathing-height center point, doors and windows in their normal position, before placing the unit.
3. 3. Place the unit on a stable, unobstructed surface clear of curtains and furniture that would block intake or discharge, and plug it into an existing grounded outlet -- no wiring, no outlet modification.
4. 4. Run the unit at its rated setting for the manufacturer's stated air-change interval, then take a second PM2.5 reading at the same point and record the percent reduction.
5. 5. Photograph the placed, running unit and label it with the room name, model, and CADR rating for the library's own record.

What counts as done

• Baseline PM2.5 reading at the room's center point before placement
• Unit model, CADR rating, and room floor-area calculation matched per EPA sizing guidance
• Photo of the placed unit running on a stable, unobstructed surface
• Second PM2.5 reading after the stated run interval showing a measured reduction

Proof is measured against these, not judged by taste.

The standard this serves

Indoor Air Quality. Indoor air quality is the health of the air where people actually live, and most of us are indoors nine hours in ten. The standards give it numbers: carbon dioxide that tells whether fresh air is reaching a room, fine dust, fumes from finishes, moisture that invites mold. Mastery looks like reading a room's air the way a doctor reads a pulse, and knowing which fix matters first. It is learned meter in hand. This packet is one room measured honestly, and one measured room is worth a hundred guesses.
