Air Cleaners & Air Purifiers
Indoor air pollution is a major problem in many homes, schools, offices, medical facilities, commercial buildings and in industry. We spend over 90% of our time indoors, where common indoor contaminants such as dust, dander, smoke, microorganisms, gases, vapors and odors can concentrate. These irritants can cause headaches, allergies & asthma, and a myriad of other potentially serious health issues for a growing number of people who demonstrate susceptibility to them.
Your Ideal Solution - Installation Of An Air Cleaner Or Air Purifier
But Do You Need An Air Cleaner Or An Air Purifier? And Which Specific Type Of Air Cleaner Or Air Purifier Is The Best For Your Particular Application?
´Air Filters´ And The Terms ´Air Cleaner´ & ´Air Purifier´
Air filtration and air purification professionals currently recognize different classes of Air Filters based upon their filtration efficiency, as measured by Minimum Efficiency Reporting Value (MERV):
Low Efficiency Air Filters are rated MERV 1-4 (Less than 20% filtration efficiency)
Medium Efficiency Air Filters are rated MERV 5-12 (20% - 75% filtration efficiency)
High Efficiency Air Filters are rated MERV 13-16 (80% - 95% filtration efficiency)
HEPA Filters are rated MERV 17-20 (99.97%-99.9999% filtration efficiency on 0.3 micron size particles)
In our experience, there seems to be a (reasonable) expectation amongst consumers that an ´Air Purifier´ will ´Purify´ Air, and that ´Purification´ implies a higher level of cleanliness than can achieved by an ´Air Cleaner´. However, there seems to be considerable inconsistency in the use of the terms ´Air Cleaner´ and ´Air Purifier´, by different manufacturers in the air filtration equipment industry. As a result, any performance difference between ´Air Cleaners´ and ´Air Purifiers´ is often a gray area.
Danforth Criteria For Differentiating Air Cleaners & Air Purifiers
In order to clarify this potentially confusing situation, our experts at Danforth have proposed and implemented the following easy-to-understand nomenclature:
´Simple Air Filters´ - Feature MERV 7 or lower rated Air Filtration Efficiency
´Air Cleaners´ (Better) - achieve MERV 8-16 Air Filtration Efficiency or Equivalent
´Air Purifiers´ (Best) - achieve HEPA Filtration (MERV 17+) Efficiency or Equivalent
As a guideline, Air Cleaners that are rated MERV 9 to MERV 12 should be capable of removing small particles in the size range 1.0 - 3.0 microns, which includes; Legionella, humidifier dust, lead dust, milled flour, coal dust, auto emissions, nebulizer drops, welding fumes...
Air Cleaners that are rated MERV 13 to MERV 16 should be capable of removing very small particles in the size range 0.3 - 1.0 microns, which includes; all bacteria, most smoke particles, sneeze droplets, cooking oil, insecticide dust, copier toner, most face powder, most paint pigments...
Air Purifier HEPA Filters are capable of removing sub-micron particles less than 0.3 micron in diameter, and must be at least 99.997% efficient (allowing no more than 3 particles in 10,000 to penetrate the filtration media). These HEPA filters endow Air Purifiers with the highest performance capability.
Electronic Air Cleaners & Air Purifiers
it should be noted that there are both Portable Electronic Air Cleaners & Air Purifiers and Fixed Electronic Air Cleaners & Air Purifiers that do not require any filters at all! These Electronic units must therefore be appraised as either Air Cleaners or Air Purifiers based upon their performance relative to equivalent Media Air Cleaners and Air Purifiers. (Example: the AtmosAir Electronic Ionization ´Air Purifiers´ perform with equivalence to MERV 13 rated Media units, and are therefore actually classed as ´Air Cleaners´ by using the Danforth Criteria).
It is also important to realize that these Danforth Criteria are not an imposed standard followed by all manufacturers when naming their products. So occasionally you´ll come across examples such as a HEPA-equipped ´Honeywell Air Cleaner´ that actually qualifies as an ´Air Purifier´ by our criteria. |
Air Cleaner & Air Purifier Types
1. Portable (Mobile) Air Cleaners & Air Purifiers
These are standalone mobile units that can easily be moved from one room to another to provide relief for allergy sufferers or to flexibly achieve your indoor air quality targets in closed areas.
2. Fixed Air Cleaners & Air Purifiers
These units may be permanently installed in room ceilings or walls to clean/purify and recirculate the air within a closed area, or they may be installed in HVAC system ducts to clean/purify air in rooms, large open office areas, or even entire buildings.
Replacement Air Cleaner & Air Purifier Filters:
For Portable Air Cleaners & Air Purifiers it is important to change out the filters as specified by the manufacturer in order to maintain efficient performance. Make sure that you buy only quality replacement filter media that meet or exceed the manufacturers´ OEM replacement filter specifications.
For Fixed Air Cleaners / Air Purifiers Replacement Filters & Pre-Filters must be installed correctly on the optimum schedule for your application. Most HVAC-Based Air Purifier installations require regular ongoing testing and certification to ensure safe and reliable operation.
