Air Check

There are so many different models of air purifiers on the market, how to know which one suits your home more? Apart from the appearance of these purifiers, the type of filter is something which should also take into account, because different air filters work differently and different target air pollutants.

One of the most popular air filters is the HEPA (High Efficiency Particulate Arrest) filter. It is a kind of filter that allows only the very small particles to pass through and can remove up to 99.97% of all unwanted particles from the air. Allergens such as pollen, mold spores and dust will be trapped in the filter and only clean air is released into the environment. The effectiveness of a HEPA filter depends on the size and material. A filter is larger able to remove more particles. Some disadvantages are that HEPA filters are more expensive compared to other filters, the periodic replacement of filters is required and is not effective in removing odors and gases.

Another type of air filter that is known as the ion generator. This type of sewage does not come with a filter. Cleans the air by ionization, so that the particles are charged and become ions, which is emitted into the surrounding air. These ions combine with the air impurities that stick in the vicinity of surfaces such as walls or floors. Some air ionizer plates consist of collections so that the impurities are attracted by these plates instead of nearby surfaces. As ion generators and ozone generators, both emit ozone is not recommended for children, elderly or people with asthma and problems lung.

Units carbon air purifiers are rarely seen because the active carbon filters are usually combined with other filters in another unit. Carbon Filters are excellent for removing odors and gases. It works by opening pores in the carbon and absorption of chemicals and gases that are too small to be trapped by a HEPA filter. However, similar to a HEPA filter, the bigger the filter, the chemicals that can absorb and eliminate. Replacing filters carbon should also be done regularly, because when full, will not be able to absorb more gas.

Today, many of the cleaners modern air two or more filters are combined in the unit work better. For example, as mentioned above, you may find purifiers that use a HEPA filter along with a carbon filter to remove most of the pollutants in the air. The type of purifier that you get depends on what kind of pollutants you want to get rid him. It is also important that you get cleaner air that states "closed system" or something similar to ensure that the unit does not allow purified and dirty air to mix together.
