Why The Right Thickness Is Important

While WEB Products makes high quality 1" filters, we understand that not all HVAC Systems take a 1" filter. Ensuring that your filter fits properly in your HVAC system means making sure that you have not only the right length and width, but also thickness of your filter. The best way to measure your air filter size is to get out the measuring tape and measure it directly.

Indoor Air Quality

What causes indoor air pollution, and why is it such a problem? With today’s economy, every effort is made to reduce energy costs. The tight insulation of buildings constructed today does decrease energy costs, but when too little outdoor air is allowed to circulate inside, air pollutants begin to accumulate inside. Common indoor air pollutants include:

  • Dust particles/dust mite debris
  • Mold spores
  • Pet dander
  • Pollen grains
  • Smoke
  • Odors
  • Bacteria
  • Viruses
  • Chemicals and gases
  • Most people spend the majority of their time indoors, breathing these air pollutants. Not only do these contaminants cause health hazards, but they also travel in the air, which places pressure on the heating and air conditioning system, leading to wear and tear and early breakdown. For this reason, it is necessary to protect yourself and your family from the harsh results of indoor air pollution.
