A good electrostatic filter can eliminate airborne particles, including nanoparticles, but it's not as good as a HEPA filter. As a rule, electrostatic filters have a 97% efficiency rate for particles 0.1 to 10 microns, while true HEPA filters work 99.97%.
The Shark Air Purifier uses Pure Air Microforce to deliver fast, powerful, and quiet purification in a compact size. Clean Sense IQ senses air quality & auto-adjusts to improve air quality and report results in real time. A HEPA filter captures 99.98% of airborne particles like allergens*, dust, and dander (based on IEST-RP-CC007.3, 0.1-0.2 microns). Cleans up to 500 square feet. *HEPA filter stands for high-efficiency particulate air filter. An actual HEPA filter will be individually factory tested and come with paperwork showing the results of these tests. A scan tested and certified H14 HEPA filter (as found in the Camfil City M) is 99.995% efficient on MPPS-sized particles on a single pass.1. HEPA Filters. High-efficiency particulate air (HEPA) filters are recommended by the U.S. Department of Health because they are able to remove at least 99.97% of airborne allergens and pollutants — including mold spores and dust that are as small as 0.3 microns. With a MERV rating nearing 16, HEPA filters provide the highest protection for
Higher Cost: Since ULPA filters have denser media and are harder to produce than HEPA filters, they cost approximately 35 percent more than HEPA filters. And the cost of filters is only part of the story. Designing a ULPA system to deliver the same ACH as a HEPA system would require a larger filter to make up for the more restrictive flow, and

The filters need to meet testing standards set out using the IEST-RP-CC001 test method. Using these methods, type C HEPA filters must remove particles 0.3 microns in size with an efficiency of at least 99.99% and J type HEPA filters must remove 99.99% of particles from 0.1 to 0.2 microns or from 0.2 to 0.3 microns. Miele Standard AirClean Filter. Formally known as the Super AirClean Filter, this model is an advanced micro-allergen filter that traps 99.95% of particles of 0.5 microns in size, and up to 94% of particles 0.3 microns in size. This model is a great value as it comes CLOSE to meeting the HEPA standard but is slightly more affordable. The conductive air filter supported a pressure drop that was 10 times lower and quality factor (QF) that was 10 times higher than a commercial high efficiency particulate air (HEPA) filter with micro/nanofiber dual layers, under face velocities of 2.5–20 cm/s as shown in Fig. 9 c. Coway AP-1512HH Mighty Air Purifier$169$230 now 27% off. Filter type: HEPA Filter | Coverage range: 874 square feet | Noise level: 24–53 dB. Three editors at New York Magazine own the Coway APA MERV 17-20 filter will typically be pretty restrictive. I tried a simlar thing with box fans and it was pretty useless, almost no flow, so I built a 24"x24"x24" box out of MDF and installed a dedicated 120VAC squirrel cage blower that is fairly loud pulling through the filters to limit how much dust buildup develops in the air handling space.
