Hello, the hourly rate is $5.0. High efficiency particulate absorption or HEPA is the process of removing particulate matter of specific size from environment. Implemented as filters, HEPA is a high end ambient air quality improvement technique. Limitation of HEPA filters is that they cannot filter individual virus strains as they are too small for the smallest pore size of HEPA filters. But since viruses ride on small particulate matter with the help of electrostatic charges, they can be removed from ambient air. Bacterial particles are easily filtered out by HEPA filters. Hence this air filtration technique ensures air quality free of infectious microbes. Still, the efficiency rating of HEPA filters is not 100% specially when the filters get particle laden over time. The efficiency can be measured by monitoring the static pressure across the filter. which indicates lower efficiency for higher pressure. HEPA filters should not get wet and should be mounted properly, and be installed with some pre-filters to ensure air quality. ----- from Principles and Methods of Toxicology 5th Ed.

Question 1. My hourly rate is normally $10 / hour, however I'm willing to accept $8 given that this is the upper limit on the job advert. Question 2. "HEPA" stands for "High-efficiency particulate absorption". (I have fitted a HEPA filter in a laboratory I used to work in!) I am new to freelancer, however I hope you will see from my profile that I have a strong background in Environmental Engineering, primarily clean fossil fuels and clean cement production. I completed a PhD with the Energy Engineering Group in the Dept. of Chemical Engineering at Imperial College London last year, the no. 1 ranked chemical engineering department in the UK. This required me to handle large volumes of data for the publication of journal papers and ultimately for my thesis. Other previous experience includes consultancy work for BP (a market review of oil spill remediation techniques), the UK Dept. of Energy and Climate Change - DECC - (a techno-economic assessment of "negative-CO2" technologies), the EU ClimateKIC (reviewing potential CO2-utilisation technologies) and for professors at Imperial College London (compiling a literature review on the interdependency of earth resources and meta-analyses on available global and land / water data). All of these projects required me to gather and organise data and to advise on the findings. I am very familiar with Excel having used it for compiling mass and energy balances on cement plants. Please contact me to discuss your project further.
