I've no idea where the fire is as I don't think it's on the dfes website, unless it's one very far way, but there's a strong smell of smoke. It's really stinks and I'm worried that the birds might get sick. Bit like the whole Canary in the coal mine scenario. Should I be very worried? The air LOOKS clear enough but it really stinks so I'm unsure. Is there anything I can do? I don't have an Air purifier..
