18x18x1 Air Filter

Your air systems work at a constant rate to bring in airflow and deliver that fresh, clean smell inside your home. Your 18x18x1 air filters will clean out passing airflow so that your ducts are free of any intruding irritants. Air filters are necessary to your home, without filtration there is no way to fully understand just what kind of irritants are floating into your home. Your air filters keep the irritants out, but they can only protect your home air systems for a finite amount of time before they need maintenance. Air filters need periodic replacement on a regular schedule or the resulting complications will begin to affect your home.

18x18x1 Air Filter Use for Residential Homes

A residential home is not always able to ensure clean indoor air by just opening a window or simply relying on the air system. The air quality outside of your home may contain high levels of pollutants or allergens that could cause some severe breathing issues. When your home suffers from low air quality, then the result is an uncomfortable, and possibly unsafe, atmosphere that has residents watching what they breathe. Your air filters are able to prevent any dip in indoor air quality, but in the process become dirty themselves and require maintenance. Dirty air filters are able to continue protecting your home against irritants but they also block airflow, causing a different set of problems entirely.

When your air filters create a blockage in your air systems, then the resulting lack of airflow leads to problems throughout your home. The inside the air throughout the various rooms in your home need to cycle out, continuous replacement prevents stagnation. When air cycling stops, and the air is not replaced, then the old air begins to stagnate and dry out. Old and dry air is unhealthy for the lungs, and over time it may cause home residents to start developing breathing problems.

18x18x1 Air Filter Use for Apartments

The average apartment has less options to endure airflow, air systems provide the bulk of clean air which means filtrations is that much more important. Airflow needs cleaning to avoid irritants from contaminating your home and causing breathing issues. However, irritants are also able to come from the inside of your home as well, especially for homes with resident smokers or pets. The irritants that fill your home’s air need to cycle out of its rooms via airflow without issue, or the particles begin to build up.

Dirty air filters stop the air in your home from flowing, from room to room, and eventually back outside. When the cycle stops, the result leads to more than stagnation, the airborne particles in a room remain as well. Lingering irritants have the tendency to cling to any open surfaces that they are able to find. your home becomes much less comfortable when its becomes covered in a layer of grime or dust, which make cleaning much harder and air less breathable.

18x18x1 Furnace Filter

Your air filters are able to fit HVAC, heating and cooling air systems alike in order to ensure clean and healthy airflow. The Filter King 18x18x1 size air filters are able to fit in appropriately sized furnace systems to provide a layer of protection. Your furnace filter fits in between the part of the furnace that heats the air and the blower fan which distributes it. Like in other air systems, the furnace filter will inevitably become dirty and incapable of processing airflow. Unlike other air systems, a dirty furnace filter may cause more severe issues that border on dangerous to your home.

The airflow in a furnace becomes warmed by extreme heat that regulates the temperature to match your thermostat. When the airflow becomes blocked, this heated air is unable to enter your ducts to warm the home, causing temperature fluctuations. The trapped air is also dangerous, causing a spike in heat the system may not be able to handle. An overheated furnace is in danger of having its parts damaged, which is very costly and time consuming to fix. A new 18x18x1 filter will help you avoid certain complications and keep the heated air flowing without incident.

18x18x1 Air Filter Changing Practices

Old air filters need replacement before any complications begin to become more obvious over time. Certain problems are easily noticed, like air stagnation or heating problems with an air system. Other issues only become evident over time, such as the increased billing a dirty air filter creates as the air systems use more energy to try and bypass it. An air systems increased use of energy also causes a faster wear down on its components, requiring costly replacements over time.

You will be able to gauge how often your air filters need maintenance at a more accurate level by taking environment and MERV rating into account. The environment of your home determines the amount of dust, debris, pollutants or molds that your filter will need to cleanse out of airflow. Your filter’s MERV (Minimum Efficiency Reporting Value) rating determines just how efficient your filter is at cleansing out passing airflow. Our 18x18x1 size air filter ranks as an 8 on the MERV scale, providing protection against irritants like:

  • Pollen
  • Dust
  • Mold
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Smoke
  • Virus’s
Replacing an Old Filter

A new filter should go into the various air systems around the house as often as monthly, depending on different factors, to avoid complications. You can see the size of the filter you needs by finding the old filter and reading its sizing off of its cardboard edge. A 18x18x1 size filters are available from FIlter King and are usable as soon as they arrive at your front door. The installation process is usually detailed more thoroughly in an air system owner’s manual.
