Which filter material can capture more particulate air pollutants?

To be sure to eliminate gases as well, you need to make sure that any air purifier you choose not only has a HEPA filter inside it, but also an activated carbon filter. Activated carbon is the only type of filter that can adsorb harmful gases and keep them under lock and key. However, keep in mind that not ALL carbon filters are created equal. Many basic air purifiers that claim to have these filters inside only have an almost negligible amount of activated carbon inside them and therefore naturally only provide a symbolic gesture of protection.

Most modern cell processing facilities have filtered air ventilation systems that use high-efficiency particulate air (HEPA) filters, a technology developed in the 1940s. With proper care and maintenance, the portable air purifier will continue to work properly and filter the air. They are used as a pre-filter in multi-stage air filtration systems to prevent large particles from reaching the main filter. The higher the MERV rating, the more effective the air filter will be in preventing the smallest particles from passing through the filter media.

In an ionizing air filter, dirty air first passes through a pre-filter, then through an ionizer to give suspended particles an electrical charge. Aluminum air filters are made of multiple alternating layers of aluminum screens to maximize their filtering and particle retention capabilities. HEPA filters are high-efficiency filters that typically capture more than 99.5% of all particulate contamination. AC filters and oven filters are types of HVAC filters and basically have the same design and construction.

Because HVAC filters operate based on air flow, it is recommended to use oven filters with a MERV rating lower than 13 if they are to be installed in residential spaces. Washable electrostatic air filters are based on an electrostatic filter medium, which is usually made of woven polypropylene or polyester. It determines how well the filter provides good air quality and is used to compare the performance of air filters. The important thing about HEPA air filters is that they are incredibly effective at capturing particles of almost any size.

Ultra-Low Particulate Air Filters (ULPA) can remove even smaller particles from the air, up to 0.12 microns in diameter with an efficiency of at least 99.99%.
