Air Cleaner Guide: What Is a MERV Rating?

Friday, February 27th, 2015

It’s estimated that over 40 million people suffer from allergies in the US. Allergies aren’t just a problem in the outdoors; indoor allergies are also a serious problem, particularly for people who are specifically allergic to dust and pet dander. One of the best ways to clean your indoor air and alleviate a great deal of suffering from indoor allergies is to employ the use of a mechanical air filter, also known as an air cleaner. However, not all mechanical air filters work alike. How do you know which air cleaner will work best for your Oregon City home? A great first step is reviewing MERV ratings with an indoor air quality expert from Clean Air Act.

What Is MERV?

The acronym MERV stands for “minimum efficiency reporting value” and it acts as a scale. This scale was created in the 1940s, along with HEPA filters, as scientists tested nuclear bomb materials and needed high-grade filters to remove harmful particles from the air. The MERV scale runs from 1 to 20 and indicates how efficient a particular air cleaner will filter the air; the higher the MERV number, the better the air filter. However, just because the MERV scale reaches 20 doesn’t mean you should install a mechanical filter with the highest number. In fact, the highest-rated air filter a homeowner should purchase typically has a MERV of 12; this is because filters with ratings between 13-20 are HEPA filters, and these filters are so strong that they can restrict the air flow in your system, which is not a good thing. If you feel you need a HEPA filter for your home, consult with an expert first.

MERV Ranges

Wondering which MERV level may be right for your home? You should always work with a professional to pinpoint this, but here is a quick overview of the scale:

  • MERV 1-4 – these MERV ratings correlate to very low capture rate, and are typically the MERV rating of the standard air filter that comes with your HVAC system.
  • MERV 5-8 – at this MERV level, the filter can capture some mold and mildew spores, pet dander, a good amount of dust particles and some dust mite debris.
  • MERV 9-12 – this level MERV is excellent for allergy sufferers, as filters at this level can capture quite small particles of all the allergens listed above, and even some biological materials.

Adding an air cleaner to your home in Oregon City can be great for your indoor air quality, but always work with an expert for installation, repair, maintenance and replacement of an air filter. Need help? Call the IAQ professionals at Clean Air Act today!

What Is an Air Handler and Why Is It Important?

Saturday, February 21st, 2015

Your HVAC system works by pushing cool or warm air, depending on the season, through your ductwork. Your HVAC is able to do this thanks to a unit called the air handler. Sometimes the air handler unit can wear out before other parts of your system, or you choose to upgrade your system and will need to install an air handler that matches the new unit. The experts at Clean Air Act bring years of air handler installation to every customer in Portland, so if you are having issues with your air handler, call us today!

What Is the Air Handler?

The air handler, also known as the blower, is the large indoor fan that blows the air generated by your furnace and/or air conditioner into your home’s ductwork for delivery into your home’s living spaces. There are two main components of the air handler, known as the blower assembly: the blower (fan), and the motor. Other important parts include the motor capacitors, the fan belt and the limit switch. Each plays an important role in the proper operation of your HVAC system.

Why Replace an Air Handler?

There are a couple of common reasons why you may need a new air handler installation. Sometimes the air handler unit can break down prematurely from aging or damage; with situations like these, it isn’t necessary to replace your entire HVAC system, just the blower assembly. In cases like these, your technician will match your new air handler as closely as possible to your current one. Other times, you may be upgrading your HVAC system, and it may be necessary to install an air handler that better matches your new system. Having an air handler that can properly handle the volume of air you need delivered to your living spaces is critical to the energy efficiency of your system and home and your personal comfort.

Not a DIY Kind of Job

Replacing your air handler is not a good choice for a DIY job. Poor installation of a new air handler can lead to numerous problems with both your air delivery and your HVAC system.

Call one of the experts from Clean Air Act and schedule an appointment for air handler installation for your Portland, OR, home.

Lupercalia: The Origin of St. Valentine’s Day

Saturday, February 14th, 2015

Many people may think of Valentine’s Day as a holiday essentially created by card and gift companies, but the truth is that the holiday has long-standing roots going back to the Roman Empire. The name “Lupercalia” has its origins in the word “lupus”, which means wolf, and the reason for this is that according to Roman pagan religion, the she-wolf Lupa nursed the two orphaned infants Romulus and Remus, the founders of Rome.

 

The Festival

The Festival of Lupercalia spanned two days each February, from February 13th to 15th. The festival was about fertility and was led by Luperci priests, known as “brothers of the wolf”. The festival was serious with intention (fertility) but was executed as quite a romp for both the priests and citizens of Rome. The process was this: two male goats and a dog were sacrificed at the beginning of the festival by the priests; two young Luperci were then anointed with the blood from the animals, and the hides of the animals were cut into straps. As food and drink flowed, the male priests would run around the city wearing nothing but thongs made from the animal skins, and they also carried a strap from one of the sacrificed animals. The strap was used to strike the palms of Roman women waiting for the priests in the city, as it was believed that being hit with the strap could help with infertility issues and a safe, healthy labor for women who were pregnant.

 

The Transition to St. Valentine’s Day

The Christian influence of the holiday came around the 5th century. The Roman Empire was still strong, but Christianity was rapidly taking hold throughout the world. It is believed that to try and remove the paganism from the holiday, the deaths of two men, supposedly both named Valentine, were added into the mix. During the 3rd and 4th centuries, a law created by Claudius II forbade young men eligible for military service to marry, because Rome wanted a strong army. The two men named Valentine were priests, and married young couples in secret. Both were found out and executed on February 14th, although in separate years. The Church made Valentine a saint (they chose one), and Lupercalia became St. Valentine’s Day.

 

Here’s wishing you and your loved one a Happy Valentine’s Day!

Reasons to Conduct Radon Testing

Thursday, February 5th, 2015

Radon is one of those terms you hear in conjunction with homes, particularly when buying and selling, but you may not understand why. The reason you hear about radon in conjunction with homes is that radon can be a serious problem. The EPA estimates that 1 in 15 homes has unhealthy radon levels. Radon infiltration isn’t specific to a geographic area, type of home, or climate. So how do you know if your home is safe? Call Clean Air Act and make an appointment for radon testing in Troutdale.

What Is Radon?

Radon is a natural byproduct of uranium breakdown in soil, rocks and water. It is an invisible odorless and radioactive gas that can cause lung cancer. In fact, radon is the number two reason why people contract lung cancer; cigarette smoking is number one. Radon is found mostly in air but it can also be found in water.

Where Is It Located?

Radon can be located just about everywhere: large buildings, small buildings, old buildings, new buildings – basically anywhere you can find rocks, water and/or soil. The problem with radon in buildings is that it can get trapped inside, and once it is trapped it can become concentrated. The good news is that there are safe levels and radon, and most people’s properties do fall into the safe category. Radon is measured in picocuries per liter (pCi/L), and to be considered safe, your home should not have a radon rating of more than 4 pCi/L. If it does, you will need to hire professionals to perform radon mitigation.

How Does Radon Get Into Homes?

These are the ways radon can enter your home:

  • Empty spaces in walls
  • Flooring cracks (in solid flooring)
  • Your water
  • Gaps between floors
  • Wall cracks
  • Joints

Mitigation

If radon is found in your home or in your water supply, the radon can be treated successfully. With water issues, point-of-use or point-of-entry devices can be used to filter out the radon from your water. Treatments for radon found in the air can vary, but one of the most common treatments is to use a vent pipe and a large fan, commonly known as a soil suction radon reduction system. This type of system pulls radon from beneath your home and expels it to the outside air. Other treatments include sealing cracks, creating better ventilation and using suction in other areas of your home.

Radon can be a serious problem. If you haven’t had a radon test, or have and need radon mitigation for your Troutdale home, call the trained professionals who can help: Clean Air Act.
