What’s the Difference between Electronic and Mechanical Air Cleaners?

Monday, September 1st, 2014

Protecting your home’s indoor air quality often requires special effort if you want both healthy air and an efficient heating and cooling system. One of the best methods to have both is to install an air cleaner for your HVAC system. These cleaners remove contaminating particles from the air that circulates through the HVAC system while providing minimal resistance to airflow. With the right air cleaner installed with the assistance of a professional, you can have close to 100% of the unwanted pollutants in your air removed.

It’s vital that you have an indoor air quality specialists help you with finding and installing an air cleaner. The wrong size and type of air cleaner can end up impairing your HVAC system or failing to adequately eliminate the particles you need filtered.

At Ierna’s Heating & Cooling, we are proud of the service we provide in improving indoor air quality in New Port Richey, FL with air cleaners. There are different types of air cleaners that we install, but most fall into two broad groups: mechanical or electrical.

Mechanical air cleaners

A mechanical air cleaner uses a mesh of material, usually fiberglass fibers, to trap particles passing through them. They both impede the particles and attract them to the surface of the fibers, where they become lodged. The most common type of mechanical air cleaner is the HEPA (high energy particulate air) filter. However, these are uncommon in homes because they can create too much blockage against airflow. Professionals will find a mechanical filter that will trap particles without creating too much air resistance.

Electronic air cleaners

Unlike mechanical air cleaners, electronic cleaners are not filters at all. They instead create an electric field that ionizes particles that pass through it. When the particles are ionized, they are drawn down to a pair of plates on the cleaner and trapped there. Electronic air cleaners require an external power source to run, but they are often necessary because they can remove contamination that is too small for a mechanical filter to catch.

Find the right air cleaner for you

Mechanical air filters and electronic air cleaners are not the only option you have for cleansing the air that flows through your HVAC system: you can also have UV lights installed or other filtration systems. There are also HVAC systems designed specifically to handle HEPA filters. There’s also no reason you can’t have more than one type of cleaner or filter installed.

Air Quality Tip: How Indoor Air Quality Devices Work with Your HVAC System

Monday, October 29th, 2012

Indoor air quality is not something that many people think about in Lutz. However, the EPA says that indoor air quality is one of the top 5 respiratory health concerns in the nation. Many people don’t realize that the air inside their home can actually be more polluted than the air outside. Without proper ventilation, humidity control and air cleaning, your air will continue to be dirty. If you’re not sure exactly how an indoor air quality control system would work with your AC system, we’ve put together a short description of how it works.

How Your Air Conditioning System Works

Most homes in Lutz have a traditional central air conditioning system. This system has an outdoor condensing unit that uses a refrigerant to remove heat from your home. The refrigerant is circulated through a series of evaporator coils inside the indoor air handler where a fan blows air across the cooled coils. The refrigerant in the coils strips the air of its heat and the air is pushed throughout the house via your ductwork.

Common Pollutants

The air we breathe is filled with all kinds of particles. These contaminants are classified into two categories: particulate matter and gaseous pollutants.  Particulate matter encompasses things like pollen, mold, bacteria, viruses, pet dander, smoke and dust.  Gaseous pollutants include tobacco smoke, vehicle exhaust, gasses from combustion of gas stoves and from the use of products like paints, varnishes, pesticides and cleaning products.

Types of Air Cleaners

Most air cleaners operate in-duct. This means that they are installed in your duct work or inside your air handler. Air cleaners can either trap the particles, using a filter or electrostatic attraction, or destroy them, as is the case with ultra-violet cleaners.

  • Particle Removal – Particle removal is normally accomplished by passing the air through a membrane that captures the particles. They can be flat or folded. These devices trap dust, pollen, some molds and pet dander. They come with a MERV rating that indicates which kind of particles it can trap. The higher the MERV rating, the more particles it will trap but the more restrictive it is to air flow. HEPA filters are a type of filter that are typically installed in medical facilities.
  • Pollutant Destruction – Some contaminants can’t be trapped and have to be destroyed. This is the case with some bacteria, viruses and mold spores. These have to be destroyed. This is accomplished by installing ultra-violet lights in your ductwork. While harmless to humans in small quantities, UV light is fatal to many kinds of bacteria and viruses.
