Philip: Oh Dad, are you repainting the wall? That’s a strong smell!Dad: Yes, the paint is full of chemicals. Put on a mask. That one was purchased for covid. Philip: Can this mask protect us from chemicals? Dad: I think so! It is written N95, BFE and PFE >99%… This should work and I feel less smell after putting it on! Philip: Masks used for covid usually filter particles like PM10. VOCs from paints are gases. We need the ones with activated charcoal to absorb the VOCs and keep us safe.Dad: Got it! I am going to get some! Wait for me to come back!!
