What is a HEPA filter?

This is an often asked question and important to understand.  Firstly let’s explain what HEPA stands for. HEPA is an acronym for HIGH EFFICIENCY PARTICULATE AIR filter.  A HEPA filter has a required minimum efficiency of being able to capture 99.97% of all particulate pollution (dust, pollen, mould, bacteria, viruses) above 0.3 microns (µm).  To put that into context the standard filtration in many HVAC/air con systems would be just 50% effective on particles sized between 3 and 10 microns.  In other words in laymens terms, a standard filter cannot...

Why is Clean Air Delivery Rate Important?

When you first start looking into air purifiers and ventilation there’s a lot of technical jargon to get your head around.  CADR (Clean Air Delivery Rate) is one term you will come across, but it’s definitely one to understand. The Clean Air Delivery Rate of an air purifier/Hepa filter tells you how efficient the purifier is at removing pollutants from indoor air.  Typically this means the effectiveness of the purifier or filter has been tested on how quickly it can remove pollen, smoke and dust from the air Normally CADR...

One major step towards significantly improving indoor air quality is the upgrading of a building’s HVAC and filter to one that is rated at MERV 13 level or higher. MERV stands for ‘minimum efficiency reporting value’, and a MERV 13 filter is effective at capturing more than 75% of particles sized 0.3 to 1 microns which means it is reasonably effective against mould spores, bacteria and smoke.  However, the Sars Cov 2 virus and Influenza particle size is around 0.1 microns, so whilst a MERV 14 filter is definitely a...
