Summary: The following guest post provides brief information about a leading company that helps to measure air quality. It helps remove these pollutants, how big of an area you want to clean, how much noise the filter makes, and what you need to do to maintain the filter.


Air quality models predict the level concentrations down point of sources. The model is to mathematically relate the effects of source emissions on ground level concentrations and establish that permissible levels are, or are not, being exceeded. Models are developed to meet these objectives for various pollutants and time conditions.


Models may be described according to the chemical conditions involved. So-called nonreactive models are applied to pollutants such as CO and SO2 because of the straightforward way the chemical reactions can represent. Reactive models address complex multiple-species chemical mechanisms common to atmospheric are applied to pollutants such as NO, NO2, and O3.


Models are simple or advanced based on the assumptions used and the degree of sophistication with which the essential variables are treated. For example, advanced dispersion modelling has been developed for such problems as photochemical pollution, dispersion in complex terrain, long-range transport, and point sources over flat terrain.


On the other hand, the most widely used models for predicting the impact of relative unreactive gases, such as SO2, released from smokestacks are based on diffusion.

In models, the spread of a plume in vertical and horizontal directions is assumed to occur by simple diffusion along the direction of the mean wind. Consequently, the maximum ground level concentration is calculated utilizing the following Equation.


Use Air Filters To Improve Air Quality


Most homes have several air filtering devices, but having the filtering devices is just a part of the solution. Homeowners need to keep those filters working effectively.


Your home’s heating a cooling system has a filter. It helps to keep unwanted pollutants out of your HVAC system and helps to increase the system’s productivity. The filter requirements to be replaced as frequently as the manufacturer recommends to keep your air clean of allergens. The filters may be a part of the air cleaning system or be located in the air return vents in the walls.


Upgrading furnace filters to high-performance models can offer you an improvement in your air quality. These high-performance filters use static to capture dust, dander, and pollen in the air. It helps to alleviate allergy and asthma symptoms in your family.


If people have a humidifier, dehumidifier, or air purifier, it may have filters that need to be cleaned or changed regularly to keep them performing as they should.


Using a vacuum with the filter will help to capture allergy-causing partials. However, this filter must also be cleaned or replaced regularly, following the manufacturer’s guidelines. Your wet/dry vac also has a filter that can upgrade to a high-performance HEPA filter that will resist clogging and make cleaning easier. Air filters are an efficient strategy to help remove irritating particles from the home.


The removable range hood filter above the stove should be washed regularly with warm water and soap. Bathroom vents should also be removed and cleaned regularly to stop a build-up of dust and dirt.


House plants are nature’s air filters. Live plants clean out air pollutants and put oxygen back in the air. They also act as humidifiers which make breathing easier. Some plants even absorb odors.


Install carbon monoxide detectors on every level


Carbon monoxide is an air pollutant that can cause death when undetected. To keep your family safe, install carbon monoxide detectors on every level of your home. The detector should be placed close enough to the bedrooms to hear even with the door closed. Smoke pollutes the air, and even secondhand smoke can cause serious health problems. Do not allow smoking in your home.


Dirt, dander, and dust are air pollutants that cause allergy issues. Cleaning your home regularly, including dusting, vacuuming, and laundering bedding can help alleviate some problems. In addition, removing shoes before entering the house helps prevent some of the dirt and dust from entering in the first place.


Mold growth from high humidity levels can be another source of air pollutants. A hygrometer measures the humidity level in your home and can help you determine if you need to run a dehumidifier. Proper maintenance of leaks and drips can also help prevent molding issues.

If you live near a large city or in an area with a high level of pollutants in the air, keeping your doors and windows closed will help keep the outside air pollution out. Newer house plans are built with a tighter construction, which has benefits but can lead to poor indoor air quality. Ventilation can improve by using attic, window, and ceiling fans to help circulate the air and keep it from getting stale. Leaving doors between rooms will also allow the air to move and circulate.


Poor indoor air quality can lead to health issues for your family. Be aware of the risks of indoor air pollution and plan to do something about it to keep your family healthy and live a good quality of life.




Indoor air quality refers to the air quality around buildings and structures, especially concerning the health and comfort of building occupants. Indoor air quality, like energy management, is a relatively young industry. Many of today’s IAQ issues stem from the energy-conscious building practices used in the 1970s. Structures were built virtually airtight to conserve electricity, causing ventilation problems and, thus, breeding some of today’s IAQ concerns.


The continuing media attention given to the health effects of toxic mold, the outbreak of infectious diseases such as swine flu, and the increase in chronic respiratory diseases such as asthma have resulted in growing interest and attention to indoor air quality in homes, commercial buildings, schools, and hospitals.


IAQ can be affected by microbial contaminants such as mold and other bacteria or any mass or energy stressor that can induce adverse health conditions. Indoor air is becoming more of a health threat than outdoor air. Determining IAQ involves:


  • Collecting air samples.
  • Monitoring human exposure to pollutants.
  • Collecting samples on building surfaces.
  • Computer modeling air flow inside buildings.


Two procedures are involved when IAQ concerns are raised: investigation and remediation. Mold investigation is identifying the location, existence, and extent of a mold hazard in a structure; mold remediation is the removal and cleanup of mold from an indoor environment.
