Review on AllergyZone AZFL 100 Filter Lock Cover by Isaac Simpson

The Wisconsin Energies - Focus on Energy - An energy auditor told me to get something like this when he did an energy audit. He told me to keep the furnace filter housing clean and yes there was enough reflux to keep the furnace running without emitting excessive carbon monoxide; then he checked every one of my smoke/carbon monoxide detectors throughout the house. A week later, a chimneyman assessing where to extend the gas line for a glass body gas fireplace specifically asked where I got that plastic/magnetic cover because his basement is dirty and he needs a furnace filter housing cover. I understand the concept but it will take me some time in our new 76 year old house to determine if this keeps the stove and entire system clean of basement floor dirt (although I have scrubbed, mopped and vacuumed the floor). a million times and some strong substances). Either way, it's easy enough to use with the magnets fully enclosed, the plastic won't rip or tear, and the two pieces provide a durable cover for the larger filter housing. Worth a try and seems essential. I'm thankful the price wasn't absurd as it is these days. Thanks very much!
