This has been amazing in a particularly bad allergy season. I live in a 1920s townhouse with poor ventilation and every time that I did any real cooking, the whole place smelled like it or the smoke detector went off. No longer! Even with something difficult like fried fish, it’s almost undetectable in the kitchen within a few minutes. I’m having less allergies and less migraines. I’m even contemplating getting a cat now. Especially during the pandemic while my family is cooped up, clean air is so important. I can’t recommend it enough.
