An ac filter is pretty gray after just a few months. Granted this will take longer to get dirty but I suspect it will look ugly before you know it.

- SOLAR_FIELDS 4y agoA good reminder to change it at least. If this were a purchasable product, I envision making the filters replaceable and the frame compatible with some standard furnace filter size, so that you can just run to the store and grab new filters when you can visually see the filter needing replacement. Contrast this with the furnace filter, which needs some other mechanism (often, a schedule) to determine when to change the filter since it's not readily visible on a daily basis.
- sampo 4y agoI read on the internet, that HEPA filters actually just filter better when they start getting clogged. But clogging increases air resistance, so you need higher power level in the fan to get the same throughput. So the economics calculation is, the cost of new filters vs. the cost of electricity of running the fan and eventually the cost of a new fan. And the comfort factor is more noise when the fan is running at higher power level. So running the filters a long time before replacing, might be the cost-saving option.
