I had the craziest grocery list the other day.
- My wife and I had been putting off shopping for weeks, only getting a few things here and there whenever one of us would be on the way home from work in the evenings.
I volunteered to take the massive shopping list to a huge supercenter in our area, which has a department and grocery store combined. First I made my way through the health and beauty section, weaving through the first aid and hair care isles while dodging dozens of other busy shoppers. My next stop was the clothing department. Anytime I take a large grocery list like this to the store, I always check the clearance sections in the women’s and men’s clothing departments. I often score amazing deals on all sorts of clothes for my wife and I, sometimes getting shirts for $1 to $3 each. The next item on my list was a new filter for our central air conditioner. My technician was explaining to me how the filters I had been using do not filter enough particulate out of the air that is necessary to keep the evaporator coil safe. Any dust microbes that are missed by the filter go straight to the coil and accumulate in large numbers. He urged me to buy a filter with a thicker mesh, but also one that ensures competent air flow and doesn’t slow the air pressure load down by any noticeable amount. Thankfully, I found a filter that is five times more effective than my old one at cleaning our indoor air. I have also noticed an improvement in performance across the board with the central air conditioner. I would have never guessed that the quality of an air filter could affect HVAC performance as much as it does.
