Somewhere in the intricate system that heats and cools a house is a relatively inexpensive, often overlooked item. A similar device is buried amid the myriad hoses and belts of many of the latest automotive air conditioning systems. Filters are the first line of defense as dirt and debris attempt to invade. The system designers included filters because keeping the garbage out makes everything run better. Blocking foreign contaminates reduces maintenance costs and prevents expensive repairs.
In an average year we change the following air filters around our house. For some the frequency is more than once a year.
- Whole house filter for the heat pump air handler
- 30 day filters in two air returns
- Air filter in the truck
- Air filter and cabin air filter in the car
- Air filter in the air purifier
- Air filter on the lawn mower
- Shop vac filter
It seems like a lot of work. Is it necessary?
Try an experiment, at your own risk, of course. Sit down. Breathe out for a 5 count. Hold it. Breathe out again for a 5 count. Hold it. Breathe out a third time for a 5 count. Hold it. Unless your next action is to breathe in you may be experiencing some light headedness. Systems which use air react in a similar manner if the intake is clogged. Restricted air flow triggers erratic performance, causes overheating, and may lead to a complete malfunction.
The owners of these homes waited too long to address their clogged filters. I am sure the cost was more than the $2 for a clean filter.
The Designer of our human minds understood the need for a good filtration system. We live in a world that generates mental junk food and if we consume too much, our system can overload. Thoughts can degrade leading us to wrong actions. Debris can obscure key warnings. Dirt can overwhelm us. Our lives can be ruined and the cost for repairs is high.
I stop for self-examination when I hit Philippians 4:8. Paul described a filter every Christian needs to put in place early in the quest for spiritual maturity. And the filter needs to be checked often to verify it is not clogged.
“Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things” Philippians 4:8 (NASB)
Here’s a spring time reminder – Change your filter!
