Airscape HEPA Tower Air Purifiers : Now Available

Arising out of our personal and professional need for high quality portable air filtration during the COVID-19 pandemic, the inspiration and launch of the the newest member of the Airscape family was born.

We noticed an absence of cost effective and high quality portable indoor air filtration products utilizing critical core attributes:

*high number of air exchanges

*quality filtration media: MERV pre-filter and HEPA filtration

*particulate level filtration appropriate for airborne size micro-droplets (i.e. COVID-19, influenza etc.

*quiet operation (suitable for conference rooms during meetings)

*efficient energy utilization (speed controllable, low energy use ECM motor)

We utilize this product in our headquarters and trust it to keep our team safe.

In case you were wondering why we should wear a mask in public and filter the air around us, check out this demonstration of suspended micro droplets.

Our CFB HEPA Filters are currently being used by a number of hospitals to create negative pressure isolation rooms for COVID-19 patients. They are typically paired with an inline fan to exhaust the contaminated air from those areas, filter and then discharge it safely outside. Discharging the air without any filtration is considered risky since you are spreading/distributing the virus particles extracted from the patient areas. If you have questions on how to build negative pressure isolation rooms give us a call.

What is a HEPA?

HEPA stands for high-efficiency particulate arrestance. To be classified as a HEPA, the air filter must remove at least 99.97% of particles whose diameter is equal to 0.3 μm. Classification at 0.3 μm is important because this is the weakest point in the filter’s performance – typical HEPA filtration efficiency increases for particle diameters both less than and greater than 0.3 μm.

Virus particles, due to their small size, typically fall in the diffusion regime of HEPA collection efficiency. Specifically, the virus that causes COVID-19 is approximately 0.125 μm in diameter. That diameter is perfectly within the particle-size range that HEPA filters capture with great efficiency: 0.01 μm and bigger (see the NIOSH diagram above).

Want to ready more about HEPA and how they filter particles the size of viruses? We found the Submicron and Nanoparticulate Matter Removal by HEPA-Rated Media Filters by NASA study is a great source of reliable technical info. Page 7 of the paper has an excellent illustration of filter efficiency as a function of particle diameter for sizes 0.01 μm and above.

HEPA Filtration for Hospitals

How times change…

A few weeks ago our sister company AirScape Fans (airscapefans.com) was ramping up whole house fan production for the summer season. Now they are very busy making HEPA filtration units for hospitals, and yes, observing Covid safety protocols. Masks [check], distancing [check], good ventilation [check], doors open for extra air dilution [check], hand sanitizer [check], outdoor breaks in the sun [check]. They (as did we!) spent a lot of time writing procedures on how to stay safe.

Stay safe and healthy out there!
