Review on Lisol Electrostatic Installation Registers, Now with Complete Features by Mark Gilbert

I have had some very bad symptoms/problems from exposure to toxic black mold. After the repair, a lot was solved, but not 100%. I found this out because after two months of living elsewhere we came back and my symptoms returned and although they were much milder they were still very annoying/debilitating. I cleaned every nook and cranny but was concerned about the venting system as the problem came from a leak in the roof/attic. I have been using these breather filters and within a day I saw significant relief. Hopefully. Excellent product and very grateful that I was able to receive it sooner than expected.
