Mold and Mold Spores

According to the CDC mold is a fungi that is found both indoors and outdoors.  Mold grows best in warm damp and humid conditions. Mold is unique in how it spreads.  Mold spores are microscopic particles smaller than ½ the width of a human hair and float around in the air.  This is how mold spread to different areas rather quickly.  Mold feeds on dead and decaying organic material such as cardboard, paper, wood, trees and plants.  Did you know that your homes air filter could be a breeding ground for mold and mold spores? Think about it, traditional air filters are made of cardboard and paper (organic materials) and are often housed in damp and dark places (in your air handler or return vent).  This is the perfect climate conditions for mold. That’s why it’s important to change your filter regularly to prevent mold from accumulating there. Or, you can go one step further and use our unique frame + filter media system.  Our stainless steel frames and synthetic filter media are 100% non organic and anti-microbial.

It’s important to keep surfaces such as counter-tops, door handles, bathrooms, floors and pet areas clean to limit and reduce bacteria.  However, it’s also important to make sure you are using a high quality air filter to remove these harmful particles from the air as well.

Energy Efficiency and Cost Savings

Changing your air filter regularly has many benefits beyond the health benefits already discussed.  It can also increase the efficiency of your HVAC system (saving you money) and prevent costly repairs to your heating and air conditioning system.

Energy Efficient System

When your air filter is not regularly changed, it becomes clogged and dirty.  The air filters job it to capture all the dust and particles in your homes air before that air gets to the HVAC system.  However, when you have a dirty filter it makes your heating and air conditioning system work harder to move the air through your system.  This added strain on your system means it has to run longer and work harder to move the same amount of air. According to the Department of Energy  a dirty air filter can increase energy costs by up to 15%.  Combine this with the fact that your HVAC system accounts for about half of your energy costs and you can see this has quite an impact on your monthly energy bill!  By changing your air filter regularly and using a high quality filter you can reduce these energy costs and keep your air conditioning system running at peak efficiency.

Cost Savings

But just using any old filter doesn’t mean your getting the best bang for your buck.  There are several types of filters on the market. The cheap throwaway fiberglass filters only capture the large dust particles.  These filters allow for good airflow (helps your systems efficiency) but don’t do a good job of filtering out finer particles that can be harmful to your system and your health.  Pleated air filters are another common type. These filters come in a wide variety of ratings and options. The higher rated (MERV Rating) filters do a good job of capturing the finer particles, but they can restrict airflow which in turn makes your HVAC system run longer resulting in higher energy bills.  Finally, you have the Forget My Filter Frame + Filter Media.  Our filters are capable of capturing the finest particles as well as the pleated filters without restricting airflow.  Providing maximum filtration and energy efficiency. Saving you money.
