What is the difference between HEPA and true HEPA?

Are True HEPA filters safe?

HEPA filters have caused controversy over concerns that they might shed tiny fibers and be harmful to health. But the latest scientific studies have shown HEPA filters are safe and found no evidence of harm.

Do HEPA filters capture viruses?

Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes. … It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above.

What is a true HEPA filter made of?

The True HEPA filter is mostly made of the highly dense paper, which is composed of very thin fibers with distances between 0.3 and 2.0 microns. The fibers are distributed randomly and oriented in all directions.

Is HEPA 13 True HEPA?

What is the H13 HEPA Filter? The H13 HEPA filter is a medical-grade air filter that can remove all particles of 0.21 microns and larger with 99.95% efficiency. Common consumer air purifiers use H11 and H12 standard HEPA filters, which can trap 0.3-micron particles at 85% to 95% efficiency.

What does a true HEPA filter do?

It is an acronym for “high efficiency particulate air [filter]” (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).

Are there fake HEPA filters?

HEPA filters are capable of trapping 99.97% of airborne contaminants down to 0.3 microns in size. According to the Environmental Protection Agency (EPA), only these filters will capture the most penetrating particle size. Unfortunately, the counterfeits, mostly found online, are not held to these standards.

What are the two disadvantages of HEPA filters?

The two cons associated with HEPA filtration include the following: Small Pollutants Can Escape Filter: Although HEPA filters capture and remove particulates larger than 0.3 microns, there is a potential for smaller particles to pass through the filter that can be hazardous when present in your air.

Is Peco better than HEPA?

Unlike HEPA filtration, PECO technology has been shown to completely oxidize and destroy pollutants such as mold, bacteria, viruses, and VOCs and thus represents substantial improvement in air filtration over any technology available in the home.

What is a V HEPA filter?

2) Air then passes through the High-Efficiency v-HEPA Filter which effectively removes up to 99% of airborne pollutant particles that pass through the system. This includes contaminant particles such as pollen, bacteria, dust mites, viruses, smoke, and other airborne impurities as small as 0.3 micron.
