Medical-grade HEPA filters are thick, pleated mechanical air filters that capture 99.97% of unwanted particles in the air. The folds create a barrier of fibers that are arranged randomly and are used to trap contaminants such as dust and dirt. Hospital air purifiers provide better filtration than HEPA to create the healthiest indoor air quality possible. These air purifiers are equipped with additional filters with which the purifiers Standard residential air systems cannot compete.
Use commercial air purifiers for offices, medical centers, dental offices, sitting areas, and other places that need the cleanest indoor environments. Medical HEPA filters are the most effective method of air filtration. While true HEPA filters are rated from H10 to H12, HEPA filters that are considered to be medical grade are classified as H13 filters. These can remove up to 99.995% of particles down to 0.1 microns. As with True HEPA, medical-grade filters must be rigorously tested before experts give them this classification.
Medical air purifiers can remove more particles than standard HEPA H11 or H12 filters, which are often used in residential environments. According to the Commercial Air Filtration team, HEPA H13 is better because it doesn't restrict airflow as much, has a better filtration/airflow ratio, and is less likely to leak air. These filters are commonly used in clean rooms that require the highest levels of air quality, for example, in the production of LCD screens. Continuously focus on the relationship between airborne air contaminants and surface biological contaminants (viruses, bacteria, molds, allergens) and the transmission of health conditions in indoor environments.
Some air purifier brands take advantage of consumers not thinking about long-term costs when buying, so they offer cheaper units that cost much more in the long term in filter replacement costs. Common air purifiers can remove PM2.5, while medical air purifiers focus on 0.3 particles that are much smaller than 2.5.The main filter they use is HyperHepa, which undergoes rigorous quality control. All filters are first tested at the factory to ensure they provide 99.97% of clean air and, if they fail, are not sent to the customer. This certification demonstrates that the filter has been thoroughly tested in a controlled environment and effectively removes 99.97% of particles as small as 0.3 microns from the air. For hospitals, you should use a HEPA-based air purifier and select your air purifier based on the CADR and hourly air changes.
Smart Air is a social enterprise certified as B-Corp that offers simple and practical air purifiers and offers free education to protect people from damage caused by air pollution. Another advantage of Dyson air purifiers is the smartphone application, with which you can operate the unit from anywhere with an integrated air quality monitor that alerts you in real time to any air quality problem in your home. For a 350-square-foot room, you would need an air purifier with a CADR of at least 224 to provide 4.8 ACH (what the EPA recommends for portable air purifiers)). An air purifier for medical use can be of great help for people who suffer from asthma, COPD, immunosuppressed or any medical problem that requires clean air free of viruses, bacteria or small harmful particles.
While this type of medical filter is capable of capturing tiny particles, such as viruses, you'll need to make sure you provide enough airflow to clean the air in your room.
