Initially effective non-woven filter

What isinitial effective filter? Many people believe that this is simply the first link in the air purification system, that its task is to capture the largest particles, and then more complex filtration takes care of the rest. In fact, this is a simplified understanding. Of course, capturing large particles is an important function, butinitial effective filterIt also plays a protective role, protecting subsequent filters from premature contamination and extending their service life. And, to be honest, assessing its effectiveness only by building dust is, to put it mildly, not enough.

The underestimated role of the first stage

Often clients come with a request simply for a 'filter that traps dust'. We explain that there is no one-size-fits-all solution and that the rightinitial effective filteris an investment in the long-term efficiency of the entire treatment system. If the first filter quickly clogs, then the entire subsequent unit - no matter how powerful it is - loses its effectiveness. It's like trying to unclog a clogged section of pipe - it won't help much. We often see situations where clients overpay for more expensive but less effective subsequent filters, simply because the first floor was chosen incorrectly in the first place.

Take, for example, an office with high traffic and intensive equipment operation. If you install a filter with a low nominal efficiency (for example, G1 or G2), then it will instantly become clogged with microparticles of dirt, pollen, even particles of industrial products, if one exists. This means that the following filters (for example, F7 or HEPA) will begin to work under increased load, which will lead to their premature failure and expensive replacement. Replacing filters is an ongoing expense, and an effective cleaning system can minimize these costs.

Types and characteristicsinitial effective filter

Most commoninitially effective filters- These are class G filters. They are divided into several subclasses, determined by their ability to retain different particle sizes. G1 – retains particles ranging in size from 1 to 5 microns, G2 – from 5 to 10 microns, G3 – from 10 to 20 microns, and so on. The choice of a specific class depends on the tasks and type of pollution. For residential applications, G3 or G4 is usually sufficient. For industrial environments where large amounts of dust and dirt are present, G10 or even higher classes may be required.

It is important to consider not only the rated efficiency, but also other characteristics of the filter, such as its resistance to air flow. Excessive flow resistance can result in increased fan power consumption and reduced overall system performance. We generally recommend choosing filters with an optimal balance of efficiency and flow resistance. This is something that is often overlooked when choosing, focusing solely on rated efficiency.

Practical experience: from failures to solutions

We have come across cases where clients choseinitial effective filter, focusing only on price. They ended up with a low-efficiency filter that quickly clogged and had to be replaced every few weeks. This led to increased operating costs and a decrease in the overall efficiency of the treatment system. We recently worked with a small manufacturing facility where an incorrectly selectedinitial effective filterled to clogging of large air systems, which caused problems with cooling of equipment and even the threat of its failure. In this case, switching to a more efficient G9 class filter helped to significantly reduce the load on subsequent filters and increase the stability of the system.

What is important to consider when choosing?

When choosinginitial effective filterIt is necessary to take into account not only the type of contaminants, but also operating conditions, such as temperature, humidity and the concentration of harmful substances in the air. For rooms with high humidity, it is recommended to choose filters with antistatic treatment to prevent condensation and mold growth. And, of course, do not forget about regularly replacing filters. Improper replacement intervals can result in reduced efficiency and premature failure of subsequent filters. We recommend diagnosing your air purification system at least once a year to assess the condition of the filters and make the necessary adjustments. Company ?Tianjin Tongchang Junqi Cleaning Equipment? actively cooperates with the Air Conditioning Research Institute of the China Institute of Building Sciences, which allows us to offer the most modern and effective solutions in the field of air purification.

Features of filters for industrial premises

Industrial premises often require specialinitially effective filtersresistant to aggressive environments and high temperatures. For example, in chemical industries, filters are used using special polymer materials that can withstand the effects of acids and alkalis. And in metalworking enterprises, it is necessary to use filters with high resistance to abrasive particles and metal dust. Selecting the appropriate type of filter for an industrial application requires careful analysis of the air composition and processes used in the plant. Using high qualityinitially effective filters– a guarantee of equipment durability and personnel safety.
