Just got a notification from my Ecobee thermostat that I should change my air filters.
But are they really getting clogged up?
I was considering taping one of these Xiaomi Aqara Temp/Humidity/Pressure Sensors to the back of a filter to see if I could use the difference between the air pressure when fan is and is not running to determine when replacement is needed.
Before I invest the time and money, I wondered if this august group had any thoughts.
There are several factors to consider:
— Some antiallergenic filters can cost $25 each
— Over replacement adds to the landfills
— Forgetting to replace them is not good for your health or your HVAC
— An most importantly, it’s a challenge to implement and to get it right
Let’s end this thread and continue the discussion in the Longue.
