Thinking about costs for each can of compressed air i bought over time would surpass cost of one device like this. Make sure use wood stick to hold fan blades as you blow air on them, not to damage the fan. If have wooden floors in room your best, but rugs where issue is more with dust and if have pets. Very dry climate there too.
