The Difference Between HEPA and Charcoal Filters

Air purifiers have become increasingly popular as levels of air pollution and fear of exposure increase. However, you may be wondering whether to use an activated carbon filter compared to a HEPA filter, at least in terms of which make the best air purifiers. To answer this question, we need to consider for what purpose you want to use the filter. Because HEPA filters cannot remove gases, VOCs and odors that are typically 0.3 microns or less, activated carbon air filters are used in air purifiers to meet the purposes that the HEPA filter cannot filter.

You would think that the HEPA filter is all you need, but you also need an activated carbon filter. Carbon filters eliminate bad odors from the air (room). The technology behind this system is very different from what is used with HEPA filters. In HEPA filters, the fiber is brought together to trap, intercept, and trap air particles moving through the filter. But in carbon filters, there is no entrapment.

Smoke, gas and bad odor are eliminated by carbon, which reacts with the unwanted odor and simply absorbs it. The outlet is clean, fresh air with a bad smell is removed. The MERV rating system measures the effectiveness of a HEPA filter. The qualities of these filters reduce exposure to particles in the designated space that could cause allergies, asthma symptoms and health problems. In addition, they improve indoor air quality without producing ozone like ozone generators do.

Ionic purifiers with HEPA filtration help further reduce hazardous materials in the air. These cleaners come in the form of electrostatic precipitators and air ionizers. Electrostatic precipitators sometimes use ultraviolet light to eradicate particles that have been irradiated by the purifier. After particulate matter passes through the HEPA filter, these filters use UV light, specifically UV-C lights, to further reduce the percentage of particulate matter in the air. Each one has its merits and its use. For example, if you're trying to reduce airborne particulates, you should consider a HEPA filter.

However, if you are worried about odors, an activated carbon filter would be better. Some air purifiers only have carbon filters that are too small, and then a problem occurs when the air purifier does not remove all bad odors from the room. But do activated carbon filters remove carbon dioxide? No, carbon filters are extremely limited when it comes to carbon dioxide removal. What many people don't realize is that there are differences between HEPA and charcoal filters (also known as charcoal) in terms of air purification. The natural defense system of the human body becomes more vulnerable and due to the inhalation of these pollutants, so allergists and doctors strongly recommend purifying household air with HEPA filters.

Changes in temperature and humidity can cause the filter to release some of the trapped organic pollutants into the air. To have an effective air purifier that can remove all kinds of bad odors and even some dangerous chemicals, you need to have a large carbon filter that is capable of absorbing significant amounts of bad odor. However, in today's society, HEPA filters have become a common method of filtering household air, as in vacuum cleaners, since they work well with small or small particles in the air. This 3-in-1 cartridge filter consists of a pre-filter, a HEPA filter and a carbon filter in the same medium. These filters are commonly used in industrial air cleaning systems and stand-alone units for domestic use. HEPA filters were originally used in World War II to remove radioactive particles from the air that affected soldiers' respiratory systems.
