There are many differences between H13 and H14 filters, the following is the specific comparison:
1. ** Filtration efficiency **
- **H13 filter ** : The filtration efficiency of 0.3 micron particle size is more than 99.95% [^2^].
- **H14 filter ** : The filtration efficiency of 0.3 micron particle size is more than 99.995% [^4^].
2. ** Application field **
- **H13 filter ** : Suitable for places with high air quality requirements, such as hospitals, laboratories, semiconductor factories [^3^].
- **H14 filter ** : Mainly used in places requiring extremely high air quality, such as advanced operating rooms, high-precision laboratories, chip manufacturing factories, etc. [^3^].
3. ** Resistance and energy consumption **
- **H13 filter ** : The wind resistance is relatively small, and the impact on the air volume and energy consumption of the equipment is relatively small [^3^].
- **H14 filter ** : Because the filter is more dense, the wind resistance is greater, which may affect the air volume of the equipment or increase the energy consumption [^3^].
4. ** Price **
- **H13 filter ** : The price is usually higher, but lower than H14 filter.
- **H14 filter ** : Due to its higher performance and more stringent production process, the price is usually higher.
In summary, there are significant differences between H13 and H14 filters in terms of filtration efficiency, application fields, resistance and energy consumption. When selecting filters, these factors should be considered according to the specific application scenarios and needs.
