Allergy Season Is Here: How to Prepare

Monday, April 16th, 2018

Paper cut of family with house and tree on fresh spring green grassThe state of your Bluffton, SC HVAC system can certainly impact your indoor air quality. For instance, if it’s an air conditioner struggling to reach the cooler temperature you have your thermostat set to, then you certainly won’t feel as comfortable indoors as you otherwise would. But when we talk about indoor air quality, we’re referring to much more than merely the temperature of your home.

We’re talking about the presence, or lack thereof, of particles and contaminants that can severely affect the symptoms of those with allergies and asthma. Springtime is allergy season, and while there’s not a whole lot we can do about your outdoor allergies, we can certainly help out in your home!

An Air Filtration FAQ

Monday, May 29th, 2017

tech-changing-air-filterAn air filter comes standard with any forced-air home air conditioning system, as you (hopefully) already know. However, few people are clear on how their air filters actually clean the air—and whether they are getting the filtration they really need from their home air conditioning systems. We want to answer some of the most common questions we hear about air filters and air filtration systems, starting with the basics.

Whole-House Air Filtration Keeps Spring Allergies in Check

Monday, May 1st, 2017

air-filter-changingAir filtration is a more important part of your air conditioner than you may think. Without an air filter in place, particulate in the air can pummel the AC unit and get caught in the blower. When the filter gets too dirty, it can block air from moving into the AC system. That’s why it’s important to change your air filter every month or so.

But a filter alone won’t necessarily protect your household from the pollutants that irritate the sinuses and make allergies act up. Learn more about why it may be necessary to add a new air filtration system to your home, and why a whole-house system is best, in today’s guide. And call our team for air filtration systems in Douglas, GA.

Are You Getting Proper Air Filtration from Your AC?

Tuesday, July 19th, 2016

Think of the last time you changed the air filter on your air conditioning system. Hopefully, it was recently (as changing the filter each month is vital for proper airflow and the continued performance and efficiency of your air conditioner). When you changed the filter, you probably noticed some level of dusty buildup on the filter, and felt confident it was doing its job.

How Is the Efficiency of Air Filters Measured?

Monday, November 3rd, 2014

Your forced-air air conditioning and heating system contains a filter which keeps you from breathing in harmful particles that may otherwise move through your ducts, including dust, pollen, animal dander, and some molds. You should replace the filter every month or so, or clean out washable filters just as often for maximum efficiency and performance. However, if you continue to replace your filter with the same type of standard filter that came included with your HVAC system, you may not be getting the quality you need. AAction Air has created this guide to help you choose the most effective mechanical filter for your AC.


The minimum efficiency reporting value, or MERV rating, is a measurement scale created to rank the effectiveness of mechanical filters. The scale goes from 1 to 16, and the numbers correspond to the percentage of particles that particular filter is able to trap. At the highest end of the scale are filters that can remove up to 95% of all particles that pass, including bacteria and smoke. If you currently use a filter with a MERV of 1-4, you may consider upgrading, as you may be missing out on a filter that also targets allergens like mold spores and animal dander.

HEPA filters

A HEPA or high efficiency particle air filter is certified by the U.S. government to remove over 99% of particles that pass through, as small as 0.3 micrometers in size. HEPA filters are actually not often used in residential application because they can hinder the efficiency of your HVAC system. If your HVAC system cannot suck in enough air through the filter, the evaporator coil may freeze or the blower motor may work too hard, eventually breaking down.

Other Considerations

You should take into account that a mechanical filter cannot remove all types of contaminants, especially since most particles in your home will settle before they make it to the vents. You may choose an electronic air cleaner to help keep even more particles out of the air.

What Do HEPA and MERV Stand For, and What Do They Mean?

Monday, July 28th, 2014

Indoor air quality is an important part of your overall comfort, and when looking for ways to improve it, there are two acronyms of which to be aware: HEPA and MERV. Each of these terms helps define what a specific air filtration system in Savannah can do for you and your home, so AAction Air has put together a little “cheat sheet” to help you.

What Is HEPA?

HEPA stands for High Efficiency Particulate Air and it is an air filter that traps particles as small as 0.3 microns (the average human hair is 100 microns) and has an efficiency rating of 99.97%. In other words, for every 10,000 particles that pass through a HEPA filter, only 3 will escape.

HEPA filters capture allergens, including pollen and pet dander, some mold and mildew spores, some bacteria and virus microbes (usually not many, though, as those particles tend to be smaller than 0.3 microns), dust, dirt and dust mites. HEPA filters can help remove smoke, but they don’t help with odors or the elimination of gases such as carbon dioxide. HEPA filters do not destroy particles but rather capture them, so to truly eradicate biological pollutants, it’s a good idea to pair a HEPA filter with a UV germicidal light. HEPA filters need to be changed approximately every 3 months and they are not washable.

What Is MERV?

MERV stands for Minimum Efficiency Reporting Value and is the industry standard for measuring the effectiveness of filters. The scale for MERV ranges from 1 to 20; the higher the MERV rating, the more particles the filter removes. Effective home filters have MERV ratings in the range of 5-12; filters with MERV ratings of 13+ are made for properties like hospitals and can seriously constrict the flow of air in your air conditioning system. There are 3 basic quality levels when using MERV:

  • 1-4 MERV – good for blocking dirt and debris for your air conditioning system, but not really for improved air quality
  • 5-8 MERV – better for air quality, and can help with dust, debris, mold spores and pet dander
  • 9-12 MERV – superior performance for air quality; recommended for homes with allergy and asthma sufferers

The most recommended MERV rating for indoor air quality is 8 and up.
