How to reduce the issue of respiratory diseases as well as allergies by choosing the RIGHT air purifier? Air pollution is getting worse, and data show more people are concerned about their health.

To determine whether an air cleaner intervention to improve home air quality will improve respiratory symptoms, quality of life, lung function and reduce the risk of exacerbations in former smokers with Chronic Obstructive Pulmonary Disease (COPD), Johns Hopkins University released trial research on the sham HEPA air purifier and HEPA air purifier.

The criteria include at least 100 participants, who have been diagnosed with COPD.

The investigator randomly assigned TRUE and SHAM HEPA air purifiers to the participants. Those participants cannot tell what’s a true HEPA air purifier. During 6 months of monitoring, the investigators will ask that a diary be kept of breathing and how the participants are feeling every day. An outcome measure indicated that COPD participants who using the TRUE HEPA air purifier has 68% lower seizures in patients with respiratory disease and 46% less probability of using rescue medication.

Proven that HEPA air purifier can effectively reduce the risks of seizures in patients with respiratory disease and the probability of using rescue medication.

How to determine the HEPA filter and other filtration options when you choose the air purifier?

• High-Efficiency Particulate Air: High-Efficiency Particulate Air（hereinafter called “HEPA”）is an equipment for purifying the air. HEPA listed filtrations have a wide range of usage, including medical devices, automobile, aircraft , and household, etc. HEPA 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).

• Pre-filter: In order to maintain the lifespan of the filter, the air purifier pre-filter removes particles from the air before the main HEPA filter. The pre-filter is to capture larger particles like dust and hair, preventing them from clogging the HEPA filter. Pre-filters are made from a variety of materials, including PE, and metal. They are washable and long-lasting. However, they cannot trap the smallest particles, including pollen, dust, dander, and particulate pollution like PM2.5.

• Functions of photocatalyst: Photocatalysts are defined as materials that decompose detrimental substances such as bacteria, and volatile organic compounds under the sun lights containing UV lights. Mainly, TiO2 is used as photocatalyst at present. Pairs of electron and hole are excited by UV lights. The detrimental substances are converted into CO₂ and oxygen in the process of photocatalyst process.

•  The negative ions: An ion is an atom, or a molecule, which has gained or lost one or more electrons. A negative ion comes from an atom that has gained one or more electrons. Ions come into contact with harmful substances in the air, the positive and negative ions undergo chemical reactions on the surfaces of the harmful. On the other hand, electrostatic precipitators (ESP)can filter out the particulate matter by using static electricity. However, the negative ions can become the harmful air pollutants unit when the particulate matter not being cleared.

• UV-C: Ultraviolet light is a type of electromagnetic radiation. This invisible radiation includes the wavelength range of 100 nm to 400 nm. The radiation is categorized as UVA (400–315 nm), UVB (315–280 nm) and UVC (280–100 nm). UV-C light emits a high-frequency, shortwave electromagnetic radiation that effectively kills bacteria, viruses, and many harmful microorganisms. UV-C light is widely used in the usage of hospitals, food factories and semiconductor manufacturing companies. The UV-C light kills viruses and harmful bacteria by using a proper way. Exposure of cells to UV-C light (280–100 nm) results in the generation of DNA damage and lesions. Results showed that UV-C light is effective for the inactivation of most DNA and RNA viruses. Use short-range UV-C light via air or water to kill bacteria and viruses through the DNA interfering cell death mechanism.

You’ll be better equipped to understand if a particular unit or system suits your needs. The best UV C+ HEPA Tyvox air purifier is the one that meets all of your requirements.
