Bests & Worsts Reviews from Amazon

I have a mast cell disease and knew something in my home was making me sick even after cutinh out all trigger foods, removing scents from candles, sprays, etc, and wearing my mask pretty much constantly. I used two of these plus two of the miniature ones in bathrooms and I feel so much better.. Evenmy spouse (with no health issues) says the house feels better. I'll definitely be getting some for upstairs.
