Our multi-room apartment in Redmond, WA, has an always running intake fan in the master bathroom advertised as a way to keep air fresh. I always wonder how effective that really is (at apartment scale) and if it's really worth the 24/7 power draw.
- asdff 5y agoProbably more for preventing mold damage from lazy tenants I imagine.
- hourislate 5y agoIt's to keep positive pressure in your unit for safety purposes. If there is a fire the fresh air will help keep smoke out of your unit and as a bonus it keeps other building odors out. Generally it is a large fan on the roof that just sucks air down a stack pumping it into every unit. You could put a filter over the register and filter that air.
- withinrafael 5y agoSorry, by intake I meant it's sucking air in. That is, air is leaving my apartment. I think you're on the right track with the safety angle here though. Will do more research.
- bbarnett 5y agoAir is leaving, thus, it is being sucked out of the apartment.
- zz865 5y agoIts probably the opposite, it sucks out air. It does stop smells from this apartment going into neighboring spaces.
- velosol 5y agoAlmost certainly designed to ASHRAE 62.2's specs so that you get enough ventilation through a combination of infiltration (leakage) and additional mechanical ventilation. It's certainly worth it and if designed as a continuous ventilation fan should be one of the lower (~15W) draw units. Not sure how to really measure effectiveness other than by trusting in the experts who came up with the spec and air quality as an indirect measure. https://homes.lbl.gov/ventilate-right/step-3-whole-building-ventilation-rate https://homes.lbl.gov/ventilate-right/step-3-whole-building-...
