Review on 🌬️ Miele HEPA AirClean SF-HA 50: High-Performance Allergen Cleaning Solution by Andrew Kay

This is a better filter than most people will tell you. The European ISO standards for air filtration provide for many different "degrees" of filtration. This filter actually corresponds to one of the intermediate standards. The base standard for HEPA certification is 99.7% particles up to 3 microns in size. This filter is better than that one. It does not meet the "Hyper-HEPA" standard, which states that 99.7% of particles are smaller than 1 micron. It's somewhere between those two. bottom line? This is a VERY good HEPA filter for vacuum cleaners. With this filter you will not be disappointed with the quality of the air coming out of the vacuum cleaner. Final remark: no VOC level; no activated carbon filter for odors or chemicals. Other than that, this is a great filter for a vacuum cleaner.
