Important Aspects of HEPA Filters That One Must Know
While buying an air conditioner or air purifier, or vacuum, many of us consider buying one that has High-efficiency particulate air filter. It is important that you know the important details about this type of filter so that you can make the right decision while buying the different products like air purifiers etc.
First, Understand What is this High-efficiency particulate air filter? The high-efficiency particulate air filter is very efficient in absorbing particulate matter. Compared to regular filters, HEPA Filters have more capability in absorbing small particles, which helps clean the air better.
These filters can capture particles of 0.3-micron size.
These filters are capable of capturing bacteria.
Take a look at the working of the High-efficiency particulate air filters: The High-efficiency particulate air filters capture the particles in different ways like impaction, diffusion, interception, and sieving. The larger particles are big in size, and they are removed by impaction.
The interception by the fibers will help to remove the medium size particles. The diffusion process will help to remove the smaller particles. In the sieving process, the particles that are large in size will get stuck between two fibers.
The High-efficiency particulate air filters, along with pre-filters made from carbon, basically increases the filter’s life. The pre-filters will help to prevent to clogging of the High-efficiency particulate air filters as they will remove the large particles.
Now the High-efficiency particulate air filter will only have to remove the smaller particles, and hence there will be less load on this filter, and the life of the filter will increase.
Here are the types of the high-efficiency particulate air filter: The general classification of the high-efficiency particulate air filter is called Minimum Efficiency Rating Value or MERV. The scale range is between 1 to 18, where 1 is least efficient, and 18 is most efficient.
Efficiency is below 20% in MERV 1 to 4 filters. Efficiency is between 20 to 35 % for MERV 5 to 8 filters. For MERV 9 to 12, the efficiency is between 40 to 75 %. For MERV 13 to 18 filters, the efficiency is very high. Now we will check the marketing classification of these high-efficiency particulate air filters. The true HEPA and Ultra Low Particulate Air or ULPA have high efficiency.
If the manufacturer says that the filter is HEPA-like or HEPA type, then these types of filters are not efficient, and do not waste your money on these filters.
Replacement of HEPA filters is required: To save money, one will naturally check the option of cleaning High- efficiency particulate air filters. It must be noted that in some cases, one may be able to clean these filters, but it is very difficult. Eventually, you will have to change the filter.
Over time, these filters get clogged, and the only option you have is to change them as soon as possible.
Here are some things that make High-efficiency particulate air filters special:
- High-efficiency particulate air filters help remove pollutants from the air, and they help purify the air. So, one gets to breathe clean air.
- High-efficiency particulate air filters will help in preventing allergies due to unclean air, and so those people who are allergic to pollen, dust, etc., will surely find High-efficiency particulate air filters to be a big advantage.
- These filters are environment friendly as they do not emit any toxic by-products.
- If you do not want any unpleasant odor in your house, then you must choose these types of filters as they help in neutralizing bad smells.
- These filters are best for those who are suffering from respiratory conditions like asthma.
Things to keep in mind while buying products that have High- efficiency particulate air filters: These days many people opt for products like air purifiers with high- efficiency particulate air filters to ensure that air in the room is clean. But while buying, you have to ensure that the product has a good quality high- efficiency particulate air filter.
The filter has to be sourced only from the best HEPA filter manufacturers in India. You must make no compromises with respect to the quality of the high-efficiency particulate air filter.
Conclusion: High-efficiency particulate air filter is known to have many advantages. It is very useful in removing pollutants from the air and keeping the air clean. But one needs to make sure that they buy the high-efficiency particulate air filter of the best company, and they need to ensure that the filter has very high efficiency to give the best results.
One needs to keep in mind that one will have to change the high-efficiency particulate air filter over a period of time as it can be clogged due to the pollutants and particles.
