The air filters in our homes and offices are manufactured without any regulation or consideration to off gassing or consumer safety other than its flammability. Tests on flammability are important because they guarantee that a product will not cause a fire. What I am concerned about is everything else. The only considerations when developing new products or sourcing new components was price, and will it make the filter catch fire. This attitude has made me question many other products on the market today. Some safeties to consider on air filter testing.
One way to make these assessments is to compare the performance standards of the different manufacturers' products according to the standards that apply via the International Standards Organization under which there are a series of standards covering compressed quality. There are nine areas of quality classification for the main contaminants as well as testing methods for them. The purity classifications dictate how much contamination is allowed.
Medias: All Medias are made from some form of synthetic fiber and most use a resin or adhesive to hold the fibers together. Some Medias that I prefer use a low melt process for the fibers to eliminate the need for resins, but almost all have resins. Newer pleated riddles that do not have metal on the back of the media for support must use huge amounts of resin to make the media stiff.
Again, I can't say if these additives are good or bad for your system. But i know that they are not "friendly" chemicals, and with all of the heating and cooling in your system, they should be evaluated for safety before going to market.
There exist variations in the quality and type of services offered in the cleaning market. Only reputable and experienced providers really know how to approach the cleaning process. They do so in a way that not leaves the strainer cleaned properly and retains its usefulness and doesn't cause any unnecessary damage.
It is generally held that there are 10 major contaminants found in compressed strainers. Nine of these are removed using filtration technology. Strainer design is based mostly on what works! In other words, development is largely empirical - the result of experiment and observation. Strainer material design and specification needs to demonstrate better than adequate retention capacity, separating ability, a stable pressure build up and low pressure loss.
Antimicrobial Chemicals: Antimicrobial agents are added to strainer Medias to prevent the growth of mold. Many suppliers nowadays market the product as "an EPA registered product". Well folks, EPA registered does not mean safe. They are registered with the EPA as pesticides! Don't use pesticides around kids, and certainly would not spray roach killer in my air conditioner and then stay in the house all day. If we want to avoid bacteria and mold, why not just change the filter more often? Really folks, pesticides? Who are these guys? If you see an antimicrobial filter, run away. There are some metals that can be used such as silver ions, so technologies are improving.
In conclusion, compressed in strainers have a wide range of applications. The selection process for the most suitable one will depend on the cost among other factors. These other factors include the contaminants to be removed, the inflight quality delivered, the operating environment, environmental impact, and the overall cost of operation over the lifetime of the product.
