HEPA Tower Air Purifier

The HEPA Tower by AirScape has been designed and built to provide indoor air quality enhancements that are needed in today's world. Although the scientific research is not over, it's becoming clear that a large component in viral transmission involves breathing in droplets or micro-droplets. 

The HEPA Tower pulls air through a MERV11 pre-filter impregnated with carbon that arrests most common particles, allergens, and odors. The next stage is a certified H13 HEPA filter that stops even minute particles. This portable unit provides clean air high up in the room and takes in room air low down in order to create a current of clean air moving from high to low and carrying any contaminants downwards to minimize human contact. The fan is powered by an ECM motor in order to provide "hum free" speed control and remarkably low energy use.

Side Note on HEPA's:  The EU standard H13 for HEPA filters (European Standard EN 1822-1:2009) specifies a 99.95% arrestance at 0.3 micron particle size. What is of interest is that the HEPA standard uses 0.3 microns as the "lowest point". This means that the filtration efficiency increases for particle diameters both less than and greater than 0.3 μm. Each HEPA filter has its own test certificate. With proper changes of the pre-filter, the HEPA filter can be expected to last 1-2 years depending upon conditions.

Specs:

• X6: 550 CFM, ECM motor with unit mounted speed control knob
• X9: 940 CFM, ECM motor with unit mounted 10 speed controller and 12 hr timer
• Very quiet: 57 dBA at full speed on the X6 model
• Low power use: 128 watts (X6 model) and 257 watts (X9)
• Footprint of 18.5″ x 26.5″ x 77″ high (with casters) 
• MERV-11 pre-filter with carbon impregnation
• HEPA H13 (EU standard) 99.95% efficient, with individual test certificate
• HEPA is 24″x24″ x 12″ deep. This means it has a lot of holding capacity
• Electronically commutated motor (ECM), very efficient
• Customizable discharge: Front, Side, Top (standard)
  

Sizing:  The goal is to have 12+ Air Changes per Hour (ACH).  Airflow in cubic feet per minute (CFM) = # Air changes per hour (ACH) x Room Volume / 60.  For example: Conference room 10’x20’x12′, with desired 12 ACH. CFM = 12 x (10x20x12) / 60 = 480+ CFM.
