HEPA Air Filtration

The LA1400 commercial HEPA air purifier is ideal for commercial and light industrial use the LA1400 models provide the best air filtration with rigid design and versatility. This unit uses the 499081 HEPA air filter with integrated carbon removing 99.97% airborne particles down to .3 micron. The 499081 HEPA filter is a mini-pleat cartridge encapsulated between two heavy-duty beverage board die-cut frames. The die-cut frames are bonded together, creating a double-wall thickness around the perimeter of the filter.

Large Area Purification

One LA1400 commercial HEPA air purifier can clean the air in a room up to 45 x 45 feet. If your room is larger 2 or more units can work together to provide the clean air you need. These units are commonly hung from the ceiling or can be wall mounted with the optional mounting bracket (#10009) . The LA1400 has 1/4-20 adapters on the bottom if you would wish to mount the unit on a cart or on wheels. Your employees and customers will welcome the clean air results! It is important to place the air purifiers in a location that will allow them to circulate air through out the room. Additional fans can be used to ensure air moves around obstacles that impede smooth air flow.

Commercial HEPA Air Purifier Process 

LakeAir Commercial HEPA air purifiers use a 3 filter process (figure 1) to clean the air in your business. As dirty air is brought to the LakeAir media filter, the larger particles are trapped by a pre-filter screen.  Smaller particles pass through to the  HEPA filter  which uses three different mechanisms (figure 2) to catch pollutants as they pass through in the moving air stream.   At high air speeds, some particles are caught and trapped as they smash directly into the fibers, while others snag on the fibers as they try to brush by. At lower air speeds, dust particles tend to wander about more randomly through the filter (a process known as Brownian motion after its discoverer, Scottish botanist Robert Brown) and may stick to its fibers as they do so. Together, these three mechanisms allow HEPA filters to catch particles that are both large and small. Clean air the passes through the activated carbon filter where odors and VOCs are removed.

Added Protection for Viruses, Bacteria and Mold

A commercial HEPA air purifier does a great job cleaning the air, however HEPA filters have their limits, especially on viruses, bacteria and mold.

Viruses:  viruses are also too small to be removed. Despite this fact, HEPA based products were marketed for a long time with the claim to protect from viruses. The US Federal Trade Commission (FTC) has now regulated that HEPA filter based products can no longer make that claim.

Bacteria: While bacteria are large enough to be trapped, bacteria are understood to release endotoxins into the air stream when dying on the air filter surface. Studies have demonstrated that endotoxins cause inflammatory and atopic responses in nonasthmatic and asthmatic participants.

Mold: Mold spores are large enough to be caught in HEPA filters but stay alive on the filter surface. Other particles that accumulate and fill the filter start acting as nutrients and allow mold spores to potentially grow on and through the filter membrane and eventually release new spores into the air.

To protect your facility from these organic threats, treat your HEPA filter with Mold Magnet. Mold Magnet will increase the capture and kill rate of  your HEPA filter by up to 1000%. Mold magnet will not shorten the life of your HEPA filter and only needs to be applied once.
