What pressure drop across an air conditioning filter is indicative of a need to replace or clean the filter as appropriate?

🔍 Key Concepts

• Filter pressure drop vs. normal operating range for typical HVAC or marine AC systems • Relationship between airflow restriction and increasing pressure drop • What would be considered a realistic alarm/maintenance threshold in inches of water column

💭 Think About

• Compare each option to what you would expect as a small, moderate, and extremely high pressure drop in a ventilation system. • Think about which pressure drop would significantly reduce airflow and efficiency but is still a practical value for routine maintenance. • Ask yourself: which value would be unreasonably low to trigger constant maintenance, and which would be so high that equipment damage or severe performance loss would likely occur first?

✅ Before You Answer

• Identify which choices represent very small vs very large pressure drops in normal HVAC practice. • Consider at what pressure drop a filter would be considered clogged enough to affect cooling performance noticeably. • Eliminate any value that would either cause constant nuisance maintenance or seem so extreme that the system would be struggling badly before someone checked the filter.
