Air Purifiers & Air Cleaners Introduction

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)

At Danforth Air Filtration & Air Purification, we find that 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 is 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.

Electronic Air Cleaners & Air Purifiers

it should be noted that there are both Portable Electronic Air Cleaners & Portable Air Purifiers, as well as Fixed Electronic Air Cleaners & Fixed Electronic Air Purifiers that do not use air filters to function.

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 HEPA Air Purifiers. (Example: the AtmosAir Electronic Ionization ´Air Purifiers´ actually perform with equivalence to MERV 13 rated Media units, and are therefore classed as ´Air Cleaners´ by Danforth).

It is also important to realize that the 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´ based upon it´s true filtration performance.

HEPA Air Purifier Types

1. Portable (Mobile) 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 Purifiers
These units may be permanently installed in room ceilings or walls to purify and recirculate the air within a closed area, or they may be installed in HVAC system ducts to purify air in rooms, large open office areas, or even entire buildings.
