Getting Started

According to studies, we spend an average of 90 percent of our time indoors. Creating an environment free of air pollution does wonders for your living situation and helps you maintain a healthy lifestyle. The filters in your heating and cooling system are simply not made to thoroughly purify the air in your home. With the right air purifiers from Abt Electronics, you can keep the air quality in your home or office clean and fresh with every breath.
Air purifiers come in all shapes and sizes, including portable air purifiers that will fit on a nightstand to cabinet styles with legs or wheels. From small rooms to large rooms, and stylish to sturdy, there is a wide selection of products to meet your needs from a range of quality companies.
One air purifier can clean the air in an entire room, and many customers purchase an additional unit for their bedroom or other areas of the house where they spend a lot of time. It is important to choose an air purifier that will be sized properly for the room it will be placed in.
Units are usually rated by the manufacturer for a recommended number of square feet. The clean air delivery rate (CADR) is another metric to consider, measuring how much air a purifier can clean within a set period of time. With multiple fan speeds available, you can choose between near-silence and maximum filtration power.
Take a few minutes and check out the Air Purifier Infographic we have created that explains interesting and useful facts about the air quality in your home.

Air Purifier Types

Filtration Systems

Filter-based air purifiers are the most popular and common type. At its core, a fan pulls air through a pleated paper or mesh filter, trapping particles inside and cleaning the air. The air filter itself can be a permanent and washable model or a replacement filter.
If you are deciding between the two of them, remember, washable filters are good for trapping dust, but they don't trap pollen and smaller particulates. Many newer air purifiers incorporate pre-filters that catch larger particles in the air flow to boost the efficiency and service life of the main filter.

Electrostatic Precipitators

The second most common type of air purifier, Electrostatic Precipitators, draw air through an electrical field and use an electric charge to capture and trap particles on charged metal plates or filters. Some units use a fan to circulate more air at a time. These air cleaners release a small amount of ozone into the air, which is an important consideration if you use the unit in a small room.


Both Filtration Systems and Electrostatic Precipitators can have built-in ionizing circuitry. Ionizers discharge electrons into the air, forming negative ions by attaching themselves to air molecules. The negative ions attract dust and pollen to form larger particles that are more easily trapped by filters.
An ionizer helps the air purifier work more efficiently. However, the ionized particles may also attach themselves to upholstery, drapes, and carpets, increasing the need to vacuum.

HEPA Filters

Many of the air purifiers we sell feature High Efficiency Particulate Arresting filters, or HEPA filters. These filters are designed to capture 99.97 percent of airborne particles measuring 0.3 microns or larger from the air. Air filters meeting this standard are also referred to as True HEPA filters.
HEPA filters trap more than just dust and fine particles. They are also very effective at removing smoke, pollen, pet dander, bacteria, mold spores, dust mites, and in models with carbon filters, even gaseous pollutants.
If you have allergies, asthma, or increased risk factors for illness, HEPA air purifiers are your best option. Studies have shown that the air indoors can be much dirtier than the air outdoors due to a variety of factors, including pets, chemicals from cleaning products, and gases from building materials and electronics.

Activated Carbon Filters

HEPA filters by themselves are not designed to properly eliminate odors. This is why many air purifiers include some form of activated carbon filter in the design to absorb odors and chemicals. If you have pets or young children at home, look for an air purifier with activated carbon to remove odors from the air. Depending on the manufacturer, carbon filters can be built into the HEPA filter or treated as a separate element.

Filter Replacements

High performance air filtration doesn't necessarily mean high running costs. In addition to many models having Energy Star certification, the HEPA filters inside are rated to last 1-2 years before filter replacement is needed. Your complete air cleaning needs are met at Abt, where we carry a full line of replacement filters for the purifiers we sell.
