LG ARNU483TMC2 Air Filter
It is highly recommended the your furnace filter is exchanged for a new one four times a year due to the filter clogging up and restricting the flow of air through the ducts. Exact measurements of the air filter can not be a choice of options because of the constraint of your air handler. LG ARNU483TMC2 filters are made in lots of filtering levels, which depends on your particular choice for how clean you want the air and the specific size of filter you need for your system.
Subtle hints your main filter needs replacing ASAP
- Manufacturers have suggested to switch out the air filter in your unit about every 90 days to keep the unit running efficiently
- The main filter looks bad and could be replaced before tomorrow
- If you place a light source behind it, the light will hardly shine through to the other side of the air filter
