What you Need to Know About Air Purification!

Types of Air Purification HEPA (High Efficiency Particulate Air) Filters – Mechanical Air Purifiers • Most common Air Filter • HEPA filter removes at least 99.97% of all particles as small as 0.3 microns.** This U.S. HEPA standard was originally developed by the Atomic Energy Commission to capture radioactive dust particles.

• Some referred to as HEPA-Type because they may not have the same cleaning capabilities as the TRUE HEPA. • HEPA filters allow only very small particles to pass through them. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter. • Main Disadvantage of the HEPA air purifier is that you have to periodically change the filter. • Main Advantage: if it is HEPA certified, then you know it works well for all common particle allergens. • Size Matters: Not all HEPA filters are created equal. The more square feet of HEPA filter, the more particulate it will be able to remove. The size, material, and construction of the actual filter media all play a role in the air purifier's performance and may account for why one HEPA filter is more expensive than another.

Electrostatic Precipitators • Charge particles and capturing them on collector plates • Main Advantages are that the collector plates never have to be replaced; they can be easily washed in the dishwasher. This type of unit is also very quiet. • Main Disadvantages: First, air flow is critical, and if not robust, it is simply recycling the same air over and over. Secondly, older and cheaper versions of this technology will actually emit ozone.

HEPA vs. ESP HEPA Filtration

Electrostatic Filtration

Functional ity

“High Efficiency Particulate Air” Filters are composed of a mat of randomly arranged fibers made of fiberglass

Lasko’s ESP is constructed of a series of metal plates and an ionizer wire. As the air particles pass through the wire, they become charged and are attracted to the stainless steel collection plates.

Captures

Mechanically captures particles as small as 0.3 microns

Can capture particles smaller than 0.3 microns since it uses a strong static field

Odors

Does not capture odors or gasses without additional filters

Fights odors without the need for extra filters

Maintenanc e

Replacement filters must be routinely purchased at the consumer’s expense

Permanent effectiveness and customers do not need to purchase replacement filters. Permanent filter can be easily washed clean with soap and water.

Sound

Louder operation caused by restrictive system

Less restrictive system can use smaller blowers

Higher energy consumption due to restrictive system. Filter loses efficiency when filter

Less energy consumption and operating costs

Efficiency

Types of Air Purifiers Ion Generators and Ozone Generators • Create charged particles (ions) and emit them into the surrounding air. These ions combine with impurities (like dust) in the air, forcing the impurities to cling to a nearby surface. Consequently, ion generators often produce dirty spots on nearby walls and floors because they do not eliminate impurities; • Simply force impurities to cling to a surface. • Ion generators were traditionally the second most popular type of air purifier, but both emit Ozone, a powerful lung irritant that is especially dangerous for people with asthma and other chronic lung diseases, children, and the elderly. • This type of filtration has largely fallen out of favor with most manufacturers, but some people will still use those to "ozone shock" rooms, for their efficacy in killing pathogens and mold.

Photocatalytic Oxidation (PCO) • New type of filtration technology. • Two components to this type of filter. • A metal plate coated in titanium dioxide attracts works in conjunction with a UV light to actually oxidize chemicals. The titanium dioxide and UV light physically break down the molecular bonds that hold large molecules of VOCs together. In doing so, a large VOC molecule can be oxidized more with each pass with the end result being carbon dioxide and water molecules. • The long term efficacy of PCO is still being researched. While it is effective in oxidizing VOCs, long strand chemicals can take several passes to full oxidize, so as a large compound breaks apart, it can actually increase the amount of a smaller derivative compound in the air, at least temporarily. • Still new and not widely researched, photo catalytic oxidation is employed by a handful of air purifier manufacturers.

Terms and Definitions AHAM Stands for The Association of Home Appliance Manufacturers. This AHAM Verifide Mark signifies that specific program attributes, relating to volume, energy and for some products, performance, have been certified by the manufacturer and independently verified by AHAM through rigorous AHAM and federal test procedures.

Antibacterial and Germicidal Filters – UV Lamps Eliminate bacteria and germs. Some utilize a HEPA filter treated with agents to kill airborne microorganisms. Other air purifiers use a UV lamp to kill germs. Air purifiers with UV filters are often used in sterile environments such as hospitals, kitchens, daycares, and labs. In residential use, they are great for controlling mold.

CADR Ratings (Clean Air Delivery Rate) (Determined by Association of Home Appliance Manufacturers AHAM) The CADR is measures of a portable air cleaner’s delivery of contaminate free air, expressed in cubic feet per minute.

Activated Carbon Filters Rarely used alone to purify the air, but they are often used in conjunction with other filters. Activated carbon/charcoal filters excel at adsorbing odors and gases and neutralizing smoke, chemicals, and fumes. When carbon is treated with oxygen, it opens up millions of pores. There are so many of these tiny pores and fissures that one pound of activated carbon has a surface area of 60 to 150 acres. This huge surface area makes it ideal for adsorbing gases and odors, providing an enormous surface area for potential bonding with chemical/vapor molecules. Must be replaced when Full.

PM2.5 The term fine particles, or particulate matter 2.5 (PM2.5), refers to tiny particles or droplets in the air that are two and one half microns or less in width. Particles in the PM2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath

Pre-Filters Remove pet hair and other large particles prior to primary filtration and come with nearly all air purifiers. Most prefilters are either foam or some sort of non-woven polyester, and some have electrostatic properties to increase filtration.

TI02 Filters Titanium Oxide. Photocatalytic oxidation is achieved when you combine UV rays with a TiO2-coated filter. TiO2 refers to Titanium Oxide. This process creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons. These highly reactive electrons aggressively combine with other elements in the air, such as bacteria and VOCs.

VOCs VOC is an acronym for Volatile Organic Compounds, which include harmful pollutants such as formaldehyde, ammonia and many other common contaminates released by building materials and household cleaners generally found in the home.
