Review on Complete Ventilaider Electrostatic Installation Registers with Enhanced Filtration by Brad Blake

This air filter material is thicker than I expected which is great. I have more confidence that it filters out allergens. There's a lot there too. They sufficed for all of my vents, and some had to be replaced as needed. I placed them inside the vents, not outside, so I trimmed the excess to make sure it covered the entire vent when I put it back into the vent so I didn't have to use the included Velcro. My father, who helped me with the installation, also bought one. This is a good product at a great price.
