    Air Filtration Systems for Your Home


  • Air Filtration Systems for Your Home

    February 16, 2018

    From bacteria and viruses to dust and dust mites, thinking about the particles floating in the air we breathe makes us uneasy. When it comes to the air we breathe, however, out of sight doesn’t mean out of mind thanks to allergies, illness or family health. If you’ve been keeping up with regular HVAC maintenance, you’re probably aware of the filters on your system. These filters aren’t your only option when it comes to air purification and cleaning. We’ll take a look at what options are available if you’re hoping to rid your home’s air of impurities.

    Filters and Beyond

    Whether you aim to purchase more efficient upgrades to your current HVAC filters, or you’re looking for a standalone air cleaning system, you’ll have three filter designs to choose from. Air filters are designed to remove particles between 1 and 3 micron from the air. Modern filters are given a minimum efficiency reporting value, or MERV, score. Keep in mind that a higher rating means better filtering efficiency, but also means decreased airflow. Impeding airflow can be bad for indoor air quality as well as your HVAC system, so you’ll want to find a good balance.

    • Standard, flat filters, which are used by default in most HVAC systems are designed to remove only the largest indoor air particles. While these particles, which include dust and dust mites, can cause humans problems, they’re damaging to the HVAC system, too, so it’s important that they’re removed. To filter smaller particles, such as bacteria and viruses, you’ll need either a higher efficiency filter, or an electronic air purification system of some type.
    • Pleated filters are an upgrade to your standard, flat HVAC filter. The accordion-shaped filter surface increases surface, which slows the flow of air across the filter, allowing for more densely, packed, smaller fibers.
    • HEPA Filters go beyond pleated designs. HEPA, or High Efficiency Particulate Air filters add both surface area and density to the filter surface. HEPA filters typically consist of submicron glass fibers designed to catch breathable air particles.

    Electronic Filtration

    There are several types of electronic filtration systems. IN many cases, these options are installed within the ductwork of your HVAC system and use a variety of methods to clean the air that passes through.

    Each type of electronic air purification technology specializes in removal of certain particulate. Your decision should be based on your HVAC system’s ability, age and your current situation. Since these systems operate best when installed by a professional, it’s a good idea to consult with your local HVAC team. Of course, if you’re in the Post Falls area, our team of certified technicians can provide guidance or assistance in making your decision or installation.

    • Electrostatic Precipitators: Among the most commonly used electronic filtration methods leverages electrical charges to remove airborne particulates. In these systems, air is drawn into the system and given an electric charge. Later, as the air passes electrical plates, the oppositely charged particles are pulled from the air and stick to the plates.
    • Ionizers: These also utilize electrical charges to remove particles from the air but do not utilize catch plates. Instead, these devices charge particles so that they cling to surfaces in the room, thereby removing them from circulation.

    Like mechanical filters, electronic air filters can be purchased as standalone systems or incorporated into your current HVAC setup. To determine what level of air purification you require, what your HVAC system is capable of supporting and how to improve your overall indoor air quality, give the experts at Mainstream Electric, Heating, Cooling & Plumbing a call today. One of our certified technicians can evaluate your needs and let you know your options.
