Alen's Best Home Filters

When airborne particles such as pollen, mold spores, pet dander, bacteria or Volatile Organic Compounds (VOCs) combine, they may trigger allergy or asthma symptoms, as well as aggravate respiratory conditions. Alen has a line of the best home filters for your Heat Ventilation and Air-Conditioning (HVAC) system that can be an excellent addition to your air quality needs, helping to trap these airborne particles and remove them from your indoor air.

Minimum Efficiency Reporting Value Levels

Airborne particles are measured in microns—one millionth of a meter—particles visible to the human eye are 50 microns or larger, with the diameter of a human hair measuring 100 microns. Particles which may cause health or respiratory issues measure 10 microns or smaller.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers utilizes the Minimum Efficiency Reporting Value (MERV) Levels test to measure the efficiency of home filters. This runs between 1-16, and explains the amount of particles that will be captured and removed. The higher the MERV rating, the more particles that will be removed.

The Best Home Filters for your Environment

The best home filters are made from materials such as fiberglass, metal and manmade, or natural fibers. Factors which may affect the filter efficiency include the fiber size, fiber density, airflow rate and diameter of airborne particles. Consider for the following when researching best home filters for your environment:

  • Panel Home Filters
    • These filters are commonly found in most homes and contain fiberglass. They meant to protect your HVAC system by removing larger particles only, meaning they do not remove smaller particles which may aggravate allergy and asthma symptoms. Panel home filters are disposable and found at most home retail stores. However, they typically have the shortest lifespan.
  • Pleated Home Filters
    • Pleated home filters are panel filters that have been pleated or folded to effectively provide more surface area. These filters are typically more efficient at collecting airborne particles than panel filters because of their increased surface area. However, as more particles are caught by the filter, airflow becomes more restricted over time. That is why it's important to change the filter on a regular basis so as not to restrict airflow.
  • Electrostatic Home Filters
    • Electrostatic home filters attract airborne particles magnetically with electronically charged filter media. While these filters can be efficient, many different types of these exist with varying lifespans. In addition, they need to be cleaned regularly and may lose efficiency over time due to particle buildup.
  • Electronic Home Filters
    • These home filters are installed within an existing HVAC system and use an electronic charge to collect and remove particles. While they are extremely efficient, removing up to 99% of particles, they can be costly and require professional maintenance.
