LAFC HEPA with UVGI Filtration
In response to the consumer’s need for protection from viral threats and general indoor air pollution LakeAir has developed several products with UVC filtration. The LAFC-HUV is a great solution to today’s new air filtration needs. The TRUE HEPA filter removes the tiniest airborne particles, even viruses from the air stream. The UVGI chamber delivers a deadly dose to microbial life resulting in ultra-clean air.
LAFC-HUV Ability to filter out COVID Sized Particles
In the past, it had been believed that HEPA filter protection stopped at 0.3 microns. However recent studies have shown that HEPA filters actually do a better job trapping nan0-particles under the size of .1 microns.
In 2016 NASA conducted a study on the removal of submicron and nanoparticulate by HEPA rated filters. The study states ” HEPA filters are nearly 100% efficient at capturing the spectrum of particles down to the very smallest airborne particles”. The study looked at the effectiveness on airborne particles as small as 0.01 microns. A graph from the study presented below graphically shows the study’s results.
These types of study findings are likely the reason that ASHRAE has urged the use of portable and local HEPA air purification like the LAFC HEPA with UVGI Filtration in all medical facilities. The protection offered by this affordable technology can be used in both medical and no medical building. Schools and offices would greatly benefit from this technology as well.
UVGI / UVC Filtration
UVGI (ultraviolet germicidal irradiation) filtration is the exposure of the airstream to UVC radiation. UVC light waves occur naturally in nature. These light rays from the sun are blocked by our planet’s atmosphere. It can be reproduced with electrical lamps and LEDs. UVC light needs to be treated carefully because exposure to it can damage your skin and eyes. Our UVGI products are thoroughly tested for UVC leakage.
For UVGI filtration to be effective, there must be a sufficient dose of UVC radiation in the UVGI chamber. LakeAir products use high output UVC bulbs a ballasts. The LAFC-HUV delivers a killing dose of over 1000µJ/cm² ( 1000 micro-joules per square centimeter) to any virus that passes through it. This amount of UVGI will ensure that any microbial that may escape HEPA filtration will be disabled before it is returned to the area being filtered.
Required Maintenance and Filter Life
The LAFC-HUV has 4 separate filter elements. The prefilter (490128) is washable and will last up to 2 years. In most cases the HEPA filter (499081) will last one year and should be replaced annually. In some cases where the air is extra dirty like smoking areas, the HEPA filter will need to be replaced more frequently. The carbon filter removes odors and VOCs from the air. It should be replaced as needed, normally every 6 months. The UVGI filter has 2 UVC bulbs, these are inexpensive and we suggest you replace them every 9 months. They have a 9000 hour life, but they do lose some of their ability to produce UVC rays as they near the end of their life cycle.
Quiet Effective Local HEPA / UVGI Filtration
The LAFC HEPA with UVGI filtration can convert any space into a safe haven from biological and indoor air pollution threats. This unit produces 48 dB(A) of sound. It will not interrupt normal conversations, making it perfect for classrooms, doctor’s offices, or any location where a quiet safe environment is required. The ASHRAE guidelines for air filtration are fulfilled with the installation of the LAFC-HUV.
