Swap the filters.

The taped-together filters on this community center's box-fan air cleaner have gone gray and stiff since the last swap, and the unit is moving less air through more resistance every week it runs unchanged. Cutting the tape, swapping in fresh matched-size filters, and re-measuring PM2.5 confirms the unit is actually cleaning the room again, not just spinning.

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

build/last-change date confirm + pre-swap PM2.5 reading + loaded-filter photo + post-swap 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. Confirm the box's build date or last filter-change date and check the filters for visible graying and loading against that date.
2. 2. Take a PM2.5 reading with the loaded filters still taped in place and the fan running at its stated speed.
3. 3. Cut the tape and remove the loaded filters, photographing them against a light source to show the visible loading, and set them aside for disposal per local waste guidance.
4. 4. Tape in a fresh set of matched-size MERV-13 filters with airflow arrows oriented the same as the original build, sealing every seam.
5. 5. Restart the fan and take a second PM2.5 reading after the stated run interval, and log the swap date for the next interval.

What counts as done

• Build or last-change date confirmed against the filters' visible condition
• PM2.5 reading with the loaded filters still running, before the swap
• Photo of the removed, visibly loaded filters
• PM2.5 reading after the fresh filters are taped in and running, showing restored performance

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.
