The air of Tehran is one of the most polluted cities in the world due to the accumulation of various types of pollution caused by fossil fuels.<\/p>\n

Concentrations of lead, carbon monoxide and other air pollutants are higher than allowed in most parts of Tehran.\u00a0In addition, the dust in the air in most parts of Tehran is higher than the allowable level, which also causes pollution.<\/p>\n<\/div>\n

\n

The internal dust of a building usually contains various substances such as bacteria, fiberglass and other irritants, toxic and allergenic that the activities of the occupants cause the movement and dispersal of dust, followed by dust particles or Through breathing or contact with the skin surface, it affects the health of the occupants of the building.\u00a0These effects, however small, will have long-term side effects.\u00a0To keep the indoor air clean, the best and most effective way is to prevent pollutants from entering and to reduce air exchange inside and outside the building by keeping doors and windows closed.<\/p>\n

By filtering the air, the amount of internal pollution can be reduced.\u00a0The use of filters or air purifiers in the ventilation system can be very effective in reducing the amount of particles.<\/p>\n

For buildings located along highways, the amount of outside air intake can be reduced, at least during rush hour.\u00a0In addition, by filtering the air, the amount of internal pollution can be reduced.\u00a0The use of filters or air purifiers in the ventilation system can be very effective in reducing the amount of particles.\u00a0Special filters must be used to treat gaseous pollutants.\u00a0It is usually not economical to use these devices in commercial environments.<\/p>\n

Types of filters
\nFurnace\u00a0filters<\/p>\n

The furnace filter is a flat, flat plate with a thickness of 4 or 7 cm.\u00a0These types of filters are mostly used for industrial purposes due to the absorption of large particles.\u00a0Particles absorbed by these filters usually have little effect on human health.<\/p>\n

Passive electrostatic filter<\/p>\n

Another type of filter is called a “passive electrostatic” filter, which has a relatively high efficiency in absorbing allergens and airborne dust.<\/p>\n

Medium efficiency filters<\/p>\n

“Corrugated filters” are another type of filter that is more efficient and is classified as a “medium efficiency” filter.\u00a0These filters, which are able to absorb significant amounts of fine and harmful particles, have different thicknesses, the thickest of which has a very high efficiency.<\/p>\n

Electronic type filters<\/p>\n

Electron-type filters are another type of filter that charges particles electrically and attracts charged particles to plates with opposite charges.\u00a0All the filters mentioned only remove particles from the air.<\/p>\n

Tips on Filters and Air
\nPurifiers Filters used in central ventilation systems should be one of the most efficient types with which the system can be operated.\u00a0“CADR” or clean air delivery rate is an indicator that determines the ability of filters to keep clean and absorb pollutants.\u00a0The point to be noted is that the use of filters will not have much effect if the amount of indoor and outdoor air exchange is high, or the interior of the building is dirty, or if the main sources of pollution are indoors.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"Air filters against air pollution The air of Tehran is one of the most polluted cities in the world due to the accumulation of various types of pollution caused by fossil fuels.
