Friedrich P-12 Air Filter
It is suggested that the filter that filters out particles from your home gets replaced every 90 days or so because the filter can get clogged and may result in poor air flow throughout the home. The actual dimensions of the filter is not a choice of options because of the constraint of whoever designed your heating and cooling system. Filters for your Friedrich P-12 are available in many filtering levels, which depends on your particular demands for clean air and whether anyone suffers from allergies in the home.
Indications your filter needs replacing
- With a light behind the air filter, the light cannot breach the other side of a completely clogged filter
- It looks dirty and maybe should be replaced before tomorrow
- It is highly suggested to swap out your air filter four times a year to keep the air inside clean and free of harmful dust
