Before purchasing an air purifier, you'll want to know a little about the different models that are available as well as which one may be the best fit for you. We have outlined some basic air purifier information below. We also have an Air Purifier Comparison Chart that will give you a quick guide to the features of each model we carry. As always, if you cannot find the information you are looking for about air purifiers, feel free to give us a call and we can answer any questions you may have.

Types of Air Purifiers

HEPA filters are an example of mechanical filtration. The advantage to this filtration method is there is no reduction in its efficiency at removing the particulates from the air over time. In fact, a HEPA filter will become more efficient as it collects more particulates, because it is so fine. The only reason you need to eventually change it is because it will start to effect the airflow through the air purifier, which will result in a loss of air cleaning capacity and also may damage the motor because of the heat that may buildup. The disadvantage to this kind of filtration is that these air purifiers tend to be noisy, especially on the higher speeds. Their filters are replaceable and can be rather expensive, especially on the more efficient air purifiers which remove more from the air over a shorter period of time. Our IQAir Air Purifiers are a top of the line air purifiers that use HEPA filters for those with serious allergies.

The more square feet of HEPA filter media there is in an air purifier, the more particulates it will be able to remove from the air before it becomes clogged. Also the air purifier will be able to remove more particulates with each pass. The quality of the HEPA filter is very important both in the material used and the design. The pleats of a HEPA filter need to be uniform so each one has the same efficiency of filtration. If the pleats are too close together they can restrict the air movement too much resulting in a loss of airflow. Some HEPA filters out there use synthetic materials and not paper. Thin paper is the best material because it will be both effective at removing the highest percentage of the microscopic particulates while not restricting airflow too much. However, the better grades of HEPA filters are extremely delicate and can be easily damaged. This is why the better air purifier companies will house the filter in such a way as to protect the actual HEPA filter material.

Electronic Air Purifiers

This type of air purifiers are called electronic air purifiers and they utilize a single or combination of technologies to clean the air in a room. An electronic air purifier works by charging the particulates upon entering the machine by an ionizer. This is a wiring mechanism that creates an electrical charge with the outcome being the particulates are negatively charged.

One type of electronic model is called an electrostatic precipitator, which consists of a series of metal collection plates that are oppositely charged to the ionized particles. It is important that the metal plates be cleaned regularly (at least weekly) in order to maintain optimial cleaning efficiency. The Friedrich C90 models utilizes this air purification method.

Another type is of electronic air purifier is the negative ionizer. This machine attempts to clean the room by eliminating the particulates from the air. The particles are not removed from the room, just from the air.

Yet another type of electronic air purifier uses a media charged filter. This means it has a electrostatic filter that will collect the particles by being oppositely charged to the ionized particles and therefore able to collect particles again as small as 0.1 of a micron. This filter will start out at a high efficiency as much as 80 to 90 percent but will decrease as the surface area of the filter becomes clogged with particulates. The filter will need to be changed out regularly in order to maintain its highest cleaning ability.

What Type of Air Purifier is Right For Me?

There are several questions you will need to ask yourself before purchasing an air purifer. One, how serious is the air quality problem you are trying to solve? If you are dealing with allergies, the more serious they are, the purer the air needs to be around you. One person with light allergies may feel fine with a cheaper quality air purifier, while somebody else with more severe allergies may find that same machine to be completely in ineffective and still be symptomatic Also, the exact nature of allergies or sensitivities is an important factor when choosing an air purifier. Different air purifiers are needed for those suffering from multiple chemical sensitivities or asthma. If a person has asthma, it is recommended they purchase an air purifier with a gas filter to control gases and odors, which can trigger an asthma attack. People with multiple chemical sensitivities can react to almost anything, so the correct choice of air purifier is extremely important, since this person could react to the material that makes up the air purifier such as glue on the Hepa filter or out gassing from plastic parts. When dealing with gas, odor, and chemical situations, the more concentrated the amount of gas contamination with perhaps a high rate of recontamination, the stronger the gas filter needed. If you wanted to control general cooking odors, you would need a basic gas filter, while cigarette and cigar smoke requires a very large and powerful gas filter. An IQAir Air Purifier would be recommended for someone with serious allergies, while someone with less serious allergies would be fine using another less expensive model such as Austin Air, Hamilton Beach, or Sharp PlasmaClustermodels.

Two, what size area am I looking to clean? Also, how much activity is there in the room as far as doors opening and closing, people walking around, etc. Hamilton Beach, Ionic Breeze, and Sharp PlasmaCluster models are ok for one room air purification, but for larger spaces you would want to consider a more industrial strength model such as the IQAir Series of air purifiers.

Third, am I concerned with the noise level of the air purifier that I am purchasing? Some people actually prefer the white noise created by some air purifiers. Others, want something that makes minimal noise. If a very quiet air purifier is high on your list, you will want to check out the Ionic Breeze model as well as the Hamilton Beach series of air purifiers.

Fourth, what is the upkeep cost of my air purifier? You need figure out how often the filters need to be changed and how much they cost. Some air purifiers may have expensive filters, but you may be able to go a longer period of time before they will require changing. It is also helpful if the unit has individual filters to change as opposed to one big expensive combined filter to change. The Austin Air Purifier line have filters that can function up to 5 years without being changed.
