Our Service for Air Purification
Design and selection
Some air filters are given a MERV rating, some a CADR, to help you determine the quality of the filter’s performance. MERV, which is the Minimum Efficiency Reporting Value, is a number designated by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) to help you compare filters. A CADR is the Clean Air Delivery Rate, which is another rating to help determine filter performance. We provide the necessary deep technical understanding and experience during this phase of the filter selection.
Installation and Validation
of the Cleanroom
We do site surveys, planning and scheduling of the project. After the installation we provide validation and leak test report of our installed filters as the case may be.
Validation has several phases, beginning with design qualification, and ending in final certification. Some of the tests performed in these phases include airflow volume and velocity tests, HEPA/ULPA filter leak testing, air movement visualization (smoke testing), room pressurization, room recovery, airborne particle count tests, relative humidity, temperature, and other testing conditions.
No matter what type of filter you choose, however, there is one final consideration. Replacement is extremely important for high quality filters. Replacement costs should be considered, as well, but replacement is definitely a necessity for proper functioning of the filter and the efficiency of your air system.
Types of Air Purifier Filters
Air Purifiers may use a wide variety of technologies to filter the air. For particulate pollution including PM2.5, bacteria and virus, pet allergens, pollen and hazardous gases, the three most common filter types are:
PRE Filter & Aluminium Filter
Polyester and pleated filters. These filters are similar to fiberglass filters but typically have a higher resistance to airflow and a superior dust-stopping ability.
Activated Carbon Filters
Activated Carbon filters have small absorbent pores that chemically react to pollutants as they pass through the filter. This causes the pollutants to bond with the carbon and become trapped. These purifiers are effective at clearing smoke, odors, chemicals and even gases from the air. Activated Carbon filters are rarely used alone to purify air, and are often used in conjunction with other filters.
By far the most common type of filter in air purifiers, HEPA stands for High Efficiency Particulate Arrestance. These filters are ideal for particulate matter, such as pollen, mold or dust. As such, they are the general favorite of those who suffer from allergies or asthma. These filters are made from multiple layers of filter material, and are required by law to filter at least 99.97% of particles greater than 3 microns in diameter.
These machines are designed to collect particles directly from the source where the dust is being created. Think of a wood sander with a dust-bag attachment that collects loose particles. With industrial-grade dust collectors, the same principle applies, only on a larger scale.
These systems are designed for high volumes of dust. They generally consist of a blower, which pulls air and dust into the unit, a filter, which takes out some of the finer particles, and a dust receptacle or bag, which collects the larger pieces, allowing you to dispose of them as needed.
Commercial Kitchen ESP Hood
- One piece compact construction assures system integrity and reduces installation cost
- Modular Design for low to high air volumes
- By reducing commercial kitchen duct cleaning and maintenance needs of high-use duct systems, customers can save up to 3/4 of their related ongoing costs.
Electro Static Precipitators
These technologies use a charge to cause airborne particles to be drawn to metal plates. The advantage of these is that they can allow better overall airflow. These are best combined with a regular air filter to ensure everything gets trapped – many units use both these technologies.
