PM2.5 refers to particles with a diameter of 2.5 microns or less, and these can easily penetrate the bloodstream. PM10, on the other hand, are inhalable particles with a diameter of 10 microns or less.
ACH stands for Air Changes per Hour. The rate determines the number of times fresh air circulates and exchanges with the old in the indoor space every hour.
ACH is the primary factor that determines how effectively air purification will be carried out.
The industry standard for effectively knocking out aerosols that carry pathogens, bacteria, and Covid Virus is 4 to 6 ACH.
According to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), the minimum required total ACH that occurs in most households is 0.35 ACH of outdoor air, and schools should be designed for approximately 10 times higher rates, although most schools do not meet this in practice. The suggestion for increasing the target to 4 to 6 ACH is more consistent with rates set in hospitals, where the higher ACH requirements underscore the potential role of air change rates as an infection control strategy.
"Providing 5-6 ACH is recommended as it will replace about 99% of the volume of air in an indoor space with fresh filtered or outdoor air every 45 – 60 minutes.” (Selection and Use of Portable Air Cleaners to Protect Workers from Exposure to SARS-CoV-2, National Institute of Environmental Health Sciences.)
CADR stands for Clean Air Delivery Rate. It measures the air volume in cubic feet per minute. In simple words, the rating determines the effectiveness of your air purifier unit. The general rule is, the higher the CADR rating, the faster your air purifier will clean the indoor environment.
HEPA stands for high-efficiency particulate air [filter], and it is a form of mechanical filter. Theoretically, HEPA filters can remove bacteria, dust, pollen, and airborne particles of size as small as 0.3 microns with 99.97 percent efficiency.
While purchasing an air purifier, it is suggested to check for the authenticity of the HEPA filters. HEPA-13 and HEPA-14 are medical-grade filters. They are the highest tier of HEPA air filtration.
The difference between the two is that H13 can remove 99.95% of particles up to 0.2 microns, whereas H14 filters up to 99.995%. If you are unsure which one is best for you, get in touch with us today.
Filters can perform and last longer under different conditions depending on many factors, including the type and concentration of contaminants in the air, population density, duration of usage, fan speed, etc. In a densely populated environment, the filters might need to be replaced every 3 to 6 months, while in areas like classrooms, the filters can last up to 12 months. The lifespan for filters described is an estimation only, based on past experiences. Euromate Pure Air cannot guarantee how long a particular filter will last under each individual user's usage conditions.
When it is time to replace the filter, the purifier has an LED indicator that alerts the user.
Filters are not covered under the Euromate Pure Air Warranty.
Air purifiers feature different types of filtration technology; hence, they all function differently. There are five main types of filters – HEPA, activated carbon, UV, ozone, and negative ion.
While HEPA technology filters invisible particles such as airborne virus particles through a fine fabric mesh, activated carbon filters are ideal for pollutants such as smoke, odors, and gases.
UV technology is highly efficient in killing germs and bacteria; however, it does not remove airborne particles; therefore, UV filters are used in combination with other filter systems.
Air purifiers with negative ion function magnetically attract airborne particles from the air, but these are known to be less effective.
Lastly, ozone filters produce ozone gas; however, health experts do not recommend it.
Indoor air pollution is a serious threat to human health. If it is not treated at the right time, poor indoor air quality can be fatal.
People with asthma, respiratory illnesses, and allergies are highly susceptible to poor indoor air quality, and prolonged exposure can trigger their symptoms to a great extent.
A Co2 monitor or a Co2 meter is an instrument to measure the level of carbon dioxide in the air around you. They are mainly used to keep track of Co2 levels in a space to help maintain air quality.
PM stands for Particulate Matter. It refers to the size of airborne particles like pollen, dust, and soot, which are usually minute and inhalable. There are two main subcategories of particulate matter – PM2.5 and PM10.
All the purifiers are Industrial and Commercial range air purifiers that are designed to effectively purify the air of different room sizes. The filters are SGS Certified for efficiency.
Our engineers size the air purifiers according to the desired ACH and cubic meterage of the air to be cleaned, at the mid-fan point to always ensure acceptably low noise levels.
