Pre-Filter Cleaning & HEPA Filter Grades
Understand how to maintain your filters and make the right choice of HEPA grades for optimal air quality.
How to Clean Your Pre-Filter
Regular cleaning of your pre-filter ensures the longevity of your air purifier. Depending on how dirty it gets, you can vacuum, brush, or wash it. When it’s time for a second clean, consider replacing the filter to maintain peak performance.
Understanding HEPA Filter Grades
H12
H12 offers the fastest airflow with moderate filtration capacity. It’s suitable for environments requiring quick airflow, but it doesn’t retain particles as effectively as higher grades.
H13
H13 is a balanced choice for most people, with moderate airflow and better retention compared to H12. It’s often seen as the standard for home air purifiers.
H14
H14 offers the highest retention capacity, but airflow is slower. It’s ideal for long-term filtration where longevity matters more than speed.Despite slower airflow
Despite the differences, real-world testing shows negligible performance differences between the grades. H14 may last longer due to its thicker filter material.
Comparison of HEPA Grades
Grade | Airflow | Retention | Lifespan |
---|---|---|---|
H12 | Fast | Low | Short |
H13 | Moderate | Medium | Medium |
H14 | Slow | High | Long |
