Filth is a broad term for any of several types of tile effects, all of which possess unique in-game appearances. Most types of filth have negative beauty and cleanliness stats. Filth does not hinder movement, manipulation, or field of view, and cannot be picked up. Filth is often spontaneous and unpreventable, with potentially disastrous consequences.

Many colonist tasks are directly impacted by the nearby presence of filth. The cleanliness room stat affects food poisoning, room quality, research speed, infection chance, and surgery success chance.

Filth is also a major factor on your colonists' mood. Pawns who have been in a filthy, ugly environment too long will gain a negative thought. Filth can quickly destroy the quality rating of an otherwise fine room, too, depriving your colonists of potential positive thoughts.

Generation

Several types of filth may stack on the same tile at the same time, with cumulative beauty effects.

A pawn's Filth Rate determines how often it spontaneously produces dirt on floors. In general, large animals produce a lot of animal filth and should thus be kept off of floors using zones. Smaller animals like the husky or cat have filth rates equal or comparable to humans.

Anytime a pawn moves on a terrain like soil, there is a chance for dirt to stick to their feet. When a pawn with dirt on their feet then walks on a non-dirt surface, like concrete or stone tile, there is a chance that the dirt can fall off their feet and create dirt on that floor. Limiting the frequency of transitions from dirt to not-dirt flooring is very important for maintaining a clean base.

Straw matting has a filth rate multiplier that affects both types of dirt generation. Straw matting will reduce the natural filth generation of pawns, like farm animals and even humans, that occur from the Filth Rate statistic. Straw matting also affects the dirt that is created when a pawn walks on a dirt surface and then walks on a non-dirt surface. When a colonist with dirt on their feet walks on Straw matting there is a greatly reduced chance that the dirt will fall off. This reduced chance does not clean the dirt off the pawn's feet.

Interactions

Filth is removed from a tile by colonists assigned to Cleaning or by rain if unroofed. Only filth in the Home area will be cleaned; tiles outside the home area will be ignored.

Limiting the home area of your colony will substantially reduce cleaning demands on your colonists. By default, a home area is automatically designated around new player structures and zones (this setting may be toggled in the lower right corner icon bar). However, home area designation is not automatically removed from an area, even if player structures are removed.

All colonists clean tiles at the same rate regardless of traits or capacities, but some types of floors, like Steel tiles and sterile tiles, are faster to clean than others. Some types of filth, like pawn trash, are faster to clean than others, like bugblood.

Outdoors: Soil does not collect dirt from foot traffic (it only adds dirt to the shoe soles of pawns), and therefore may be more beautiful to use outdoors than constructed streets. However, in comparison to streets/paths in the base state soil tiles are only of neutral beauty and have a walk speed penalty.

Indoors: Soil does collect animal filth from Filth Rate. Indoor Soil also spreads dirt to pawns’ shoes. Indoor Soil has -1 cleanliness and -3 beauty per tile indoors.

Summary table

Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside. Some messes can be spread by pawns tracking through them and others can be washed away by rain.

The effect of filth on outdoors beauty is 30% of the effect indoors.
