Different Types of Air Cleaners and Filters
The most common filters found in a typical residential HVAC system are mechanical air filters removing physical particles (dust, dander and lint) from the air. When it comes to air cleaners, different types serve different purposes and match certain heating or cooling systems. They also vary in the type of material used to optimize their filtering efficiency. Below are some of the most common types of filters and air cleaners.
|Types of Air Cleaners||The most common filters found in the home||Specialized filters and cleaners|
|Mechanical filters||Fiberglass filters||High-efficiency Particulate Air filters (HEPA filters)|
|Electronic air cleaners||Pleated filters||Electrostatic filters|
|Ion generators||Washable filters||UV lights|
Professional HVAC technicians can make the best suggestions on how to replace your air filters and what best to replace them with, by considering factors such as:
- Your space
- The requirements of your heating or cooling system
- Frequency of replacement or cleaning
Why You Should Change Your Air Filter
The most basic function of an air filter is to remove impurities from the air. These impurities may range from particles that are visible to the naked eye to even smaller particles that can make their way to your lungs. Impurities such as dust, pet dander, pollen, mold, and even some types of bacteria can be efficiently filtered by air filters.
All types of air filters are rated on their ability to purify the air. However, over time and with constant use (i.e., when your ventilation system is running), the quality and performance of your filter degrades. Here are the top 4 reasons why you should change your filter:
- Improve your air quality Each filter has a peak efficiency and depending on whether or not they are reusable or disposable, once your filter has served its time, you must replace it to still get efficient performance from your ventilation system. An old and clogged filter will not work properly, so changing it is necessary.
- Improve your temperature control A clean and properly installed air filter helps your HVAC system produce the right amount of cooled or heated air by letting fresh air pass through. The internal temperature of your space will be better controlled when a clean filter allows the right amount of air circulating in your system.
- Prolong the life of your heating or cooling system Consider your HVAC system the lungs of your home or your building. By having your filter regularly cleaned or routinely replaced you are not only cleaning the air you breathe, you are also reducing the number of air particulates which make it to the interiors of your system. This helps keep your systems cleaner from the inside.
- Improve your energy efficiency Relative to allowing your equipment to “breathe”, changing out old air filters allows your HVAC system to be more energy efficient by reducing the amount of mechanical stress it goes through when absorbing air. Clogged filters make your system work to push and pull air in harder, therefore consuming more energy. By changing old air filters, you save costs on your energy consumption too.
The amount you spend on regularly changing your air filters will ultimately pay itself off in terms of reducing unit repairs and cutting energy consumption costs. When was the last time you had your air filters checked and changed?
Preventative Maintenance Program
Why should you perform preventative maintenance and join the Marx comfort club?
Over time as your heating and cooling equipment ages, parts can wear out or work less efficiently than they once did. Sometimes this wear and tear can put additional strain on the equipment causing them to fail sooner than the expected useful life. A skilled technician can perform preventative maintenance to ensure that your equipment is operating within manufacturers’ specifications confirming its efficiency, longevity and safe operation.
During the visit technicians visually check system components for wear and tear as well as perform tests using specialized equipment. Tools like a manometer, electrical multimeter, temperature probe, compound refrigerant gauges, and combustion analyzer are used to evaluate the operation of your heating and cooling system.
