changed the home air filtration industry when they introduced Filtrete furnace filters -
and now you can benefit from that same Filtrete technology in a room air purifier! Not only are
Filtrete air purifiers effective, but they're also small, convenient, and stylish. The
3M Filtrete Ultra Clean Air Purifier
is better than HEPA at capturing airborne particles; it has a higher airflow and the electrostatic nature of the filters lends itself to higher dust and pollen
capture rates. The 3M Filtrete Ultra Quiet Air Purifier
is the quietest air purifier on the market for its size. Between the two lines, Ultra Clean and Ultra Quiet, you have only a few major distinctions. The
3M Ultra Clean air purifiers cover larger areas and have a few additional features like a filter change timer or filter monitor. the Ultra Quiet air
purifier models are generally smaller, do not have any additional features and some have fewer fan speeds. Regardless of the size or features, the technology is
the same in each air purifier 3M produces.
Founded by five businessmen in Two Harbors, MN in 1902, 3M started out as a mining
company. They produced the world's first waterproof sandpaper in the 1920s. In 1925, a young
lab assistant named Richard G. Drew invented masking tape; in the following years, 3M developed
the Scotch tape brand. The 1950s brought Scotchgard fabric protector, videotape, and
scotch-Brite cleaning pads, along with several other new 3M products.
In the 1960s and 1970s, 3M expanded to produce specialized products for industries such as photography,
pharmaceuticals, radiology, medical equipment, and dental equipment. The famous Post-It notes appeared
in 1980. In the 1990s, 3M product sales hit the $15 billion mark. 3M is one of 30 companies that make up
the Dow Jones Industrial Average. Sales hit $20 billion in 2004, and 3M now produces an astonishing array of
products, from respirators, air purifiers, and air filters to optical films for LCD televisions and immune response modifier pharmaceuticals.
