Differences Between Mechanical and Electronic Air Cleaners

Sunday, February 1st, 2015

Air cleaners not only improve the quality of your indoor air, they can also improve your health. When it comes to choosing an air cleaner, homeowners have two options: a mechanical air filter or an electronic air filter. Both capture contaminants, but each does so in a different way. Installing a whole-home air cleaner in Edmonds can be much more effective than using room-by-room air cleaners. The experts at G&S Heating, Cooling & Electrical, Inc., have been helping customers improve their indoor air quality since 1977 and can help you choose and install an air cleaner that is right for you.

Mechanical Air Cleaners

Mechanical air cleaners are the most commonly used and recognized of air cleaners. Mechanical air cleaners are named as such because they use a filter media stretched in a frame to capture the contaminants in your home. Mechanical filters are rated by a system known as MERV; the higher the MERV number, the better the filter. Whole-home air filters have a MERV range typically between 5-12; any higher than a MERV of 12 can restrict the airflow in your HVAC system. Depending on the MERV rating, mechanical filters can capture dust, dirt, pollen, pet dander, some mold and mildew spores, some bacteria and some viruses.

Electronic Air Cleaners

Electronic air cleaners use electricity to clean your air. There are two types of electronic air cleaners: ion generators and electronic precipitators. Ion generators use negative ions to capture contaminants in the air. The process is simple: the generator disperses negative ions into the air of your home. The negative ions attach themselves to the contaminants in the air, becoming one particle. The negatively-charged particles are attracted to the surfaces in your home and land there; they are removed when the surfaces are cleaned.

Electronic precipitators draw air into an ionization chamber with a fan. Once inside the chamber, the contaminants in the air are charged; as the newly-charged particles move through the precipitator, they are collected on oppositely-charged metal plates.

How Do You Measure Your Air Cleaner’s Performance? A Question from Bothell

Friday, November 4th, 2011

Your air cleaner is designed to keep your family comfortable and healthy in your Bothell home, regardless of what contaminants make their way inside. This is important because homes these days are sealed up tightly to minimize the loss of heating or cooling, but as a result they have poor ventilation and frequently they will suffer a buildup of excess contaminants like mold, dust, pollen and dander.

To ensure you get the best possible air cleaner for your home, there are a number of measurements available to help you in the purchasing process. Let’s take a look at a couple of those measurements and what they mean.

MERV

MERV ratings are used to measure the ability of a filter to remove dust from the air that passes through it. The higher the MERV rating, the better the filter works at removing particles. The MERV rating scale goes from 1-16 with 16 being the best possible rating you can obtain from a residential (non-HEPA) grade filter. Usually, they are designed to measure things like dander, dust, smog, wood smoke, spores, bacteria and mold.

When choosing an air cleaner, it is recommended that you look for a MERV rating of at least 8, which is good enough to remove almost all common household contaminants. Higher MERV ratings (17 and up) are found in HEPA filters which are considered among the best on the market, able to remove particles as small as 0.3 microns.

CADR

This rating stands for Clean Air Delivery Rate and is a measurement of how efficiently the air cleaner delivers clean air for tobacco smoke, pollen and dust (the common measurements given for each device). This is not a measurement of the efficiency of the device, so much as the speed of it the device. So, the higher the CADR measurement for all three contaminants, the faster those particles are removed from the indoor air.

The best way to choose a device to match your needs is to look for a CADR rating of at least 2/3 of the size of the room you are cleaning. So, if you are cleaning the air of a 150 square foot bedroom, you should get a device with a CADR rating of at least 100.

When choosing a good air cleaner for your home, make sure you do your research and choose on the best possible option for the space you need to clean. MERV and CADR allow you to do this.

Will My Air Cleaners Reduce Health Risks? A Question from Monroe

Friday, October 28th, 2011

There is a lot of talk these days about how important it is to have a good air cleaner in your Monroe home. If you don’t have one, you’re putting yourself at risk, or so says common knowledge. But, do air cleaners really reduce health risks, and if so, by how much?

What Air Cleaners Do

Before we can say whether an air cleaner has any positive health effects, we must first look at what they do. Air cleaners are designed to remove certain particles from the air inside your home. Different air cleaners are designed for different levels of removal.

Ratings like the MERV of an air cleaner measure how small of particles the device can remove. Additionally, the type of cleaner will determine what it is best at removing. Mechanical filters are the most efficient at removing dust, pollen, and dander while electronic filters are best for smoke, bacteria and mold spores.

So, What Impact Does this Have on Health?

The big question then is what kind of health benefits you will gain from a high end air cleaning system. If your home isn’t prone to a large number of contaminants and you have good ventilation, the difference may not be that big, but for those with a well-sealed home, pets, humidity problems or any number of other indoor air contaminant sources, an air cleaner has a tremendous impact on your health.

The problem is that when the house gets sealed up so tightly, we put our bodies at risk of contamination from gasses and pollutants that would otherwise dissipate into the air. Those with asthma are put at an increased risk as they breathe in a variety of different triggers like dust, mold and dander.

An air cleaner removes these threats and while they don’t have a proactive effect on your health – you won’t suddenly lose weight or never again get the flu – they can remove many of the negative effects that poor air quality has on your body.

So, should you get an air cleaner for your home? In most cases, the answer is yes, but if you’re still not sure, consider getting your air quality tested. This way you’ll know exactly what you’re breathing and what kind of impact it’s having on the health of you and your family.
