Our Service for Air Purification

Design and selection
of Filters

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.

Superior Customer

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 filters maestro
Applications without hygienic demands. Example: General production areas in the automotive industry. Production areas of the heavy industry. Examples: Steel mill, smelters, welding plants

PRE Filter & Aluminium Filter

Washable air filters. These products are not as common and rely on the build-up of dust along the cloth to improve the efficiency of the filter. Industrial processes involving high volumes of coarse dust are typical applications.

Medium Filter

Fiberglass filter. This throwaway air filter is the most common type. Layered fiberglass fibers are laid over each other to form the filter media and typically are reinforced with a metal grating that supports the fiberglass to prevent failure and collapse.

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.

Carbon Filter

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.

HEPA Filter

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.

Applications with high hygienic demands. Examples: Hospitals, pharmaceutics, electronic and optical industry, supply air to clean rooms. Applications with medium hygienic demands. Example: Food and beverage production.

Dust Collectors

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

Exhaust range hood is one of the important part of the ventilation system. Our hood style ESP is a special hood inside with electrostatic filters. The function is not only to extract the cooking smoke and grease vapor, but also to filter the cooking fumes and grease particles by electrostatic precipitator. ESP hood combines kitchen canopy exhaust hood with electrostatic filtration system which can be installed directly over the cooking appliance.


  • 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.
