The US Environmental Protection Agency conducted studies that show indoor air can contain 10 times more pollution than outdoor. Air indoor air pollution can affect health and personal comfort irritating the nose throat eyes and can induce fatigue and headaches while provoking asthma allergies. There are many sources inside the home that contribute to indoor pollution pollen dander tobacco smoke fumes and vapours skin flakes microbiological growth bacteria and viruses and dust mites. Although some of these airborne particles are captured through the air filter most are too small and passed through into the airstream.
what should we do? Let me introduce you to air filters.
TYPES OF AIR FILTERS
The various types of air filters based on the air filters’ usage are divided into two major categories: primary air filter or pre-filter number two is a secondary filter or final filter.
– Disposable pleated filter
– Washable panel filter
– washable pleated filter
– Nylon mesh filter
– Carbon filter
– Steal mesh filter
– Bag filters
– Rigid filters
THE DIFFERENT TYPES OF HVAC FILTERS
There are several types of filters on the market. Which one you choose for your system is the amount of purification you want and the quality of air in your home all depends on the type of HVAC filter that you have. The average air filter’s primary function is to protect the central air system from larger airborne particles. Unfortunately, the standard filter is unable to capture smaller particles when these smaller particles collect inside of the central air system it can result in more service calls higher maintenance costs and energy bills.
First of all, washable filters. Reusable filters or washable filters an option for those who enjoy saving money is washable filters reusable are washable filters that can simply be cleaned up and used again this type of filter is typically expensive than the disposable kind and have a low Merv rating between one and four. This makes reusable air filters prone to mould or mildew growth through this filter can save you money. It’s important to know that since you are using water to clean it there is a risk of mould and mildew and eventually needs to be replaced with a new filter. Keep in mind these reusable air filters have a very low Merv rating between 1 and 4.
Then we have fibreglass filters which are also called flat-panelled fibreglass filters. fibreglass air filters are constructed from fibreglass material and have a thin flat surface. They are designed to protect your HVAC system not to improve the air quality in your home. These filters remove less than 10% of pollutants in the air and get a Merv rating between 2 and 4. A fibreglass HVAC filter may be right for you if you don’t have any pets allergies or chronic respiratory conditions.
Next is pleated filters (also called an extended surface filter) Pleated air filters are constructed from polyester, material and have a pleated surface to increase their efficiency these filters can remove up to 30 to 45 of the pollutants in the air and get a Merv rating between 8 and 13. These filters are disposable and the design of this type of filter is intended to increase the surface area, which improves its filtration efficiency as well. These filters are similar to fibreglass filters but typically have a higher resistance to airflow and a superior dust stopping ability.
Pocket air filters (also called bag filters) are constructed of a plastic or galvanized steel frame and contain fibreglass or synthetic media. They are called pocket filters because the media is stitched from filters pockets ranging from 10 inches to 36 inches in depth. They offer Merv ratings up to 14 and efficiency up to 95%. Pocket filters are usually used as final filters in commercial applications or as pre-filters in pharmaceutical or hospital applications.
Now electrostatic HVAC filters. By Merv raging between 2 to 10 electrostatic filters feature self-charging fibres that attract particles from the air without increasing the tightness of the weave, this allows air to pass through efficiently while making it possible to trap a greater number of particles measuring 8 to 16 microns. Unlike other types of filters, electrostatic filters come in washable versions. These cost more upfront, but because you can clean and reuse them electrostatic HVAC filters may be suitable if you want better filtration with ample airflow.
High-efficiency particulate air (HEPA) filters are the most efficient available. At Merv 17 to 20 they can trap 95% or more of mould, dust, asbestos, bacteria, and viruses measuring as small as 0.3 microns. Most HEPA filters are made from a mixture of glass fibres that are interlaced particles are captured in one of four ways: direct impacting, interception, diffusion, or sieving.
ultra-low particulate air (ULPA) filters are closely related to HEPA filters but are even more efficient. ULPA filters are specified to remove 99.999% of contaminants 0.12 micron or larger in diameter.
ULPA filters are used in air filtration and purification systems to control airborne particulate levels and to stop the spread of toxic agents and infectious diseases.
The air you breathe is so important. Your very basic needs depend on it, you can not live in dusty, polluted air! So you actually need to keep it clean and air cleaners are the best solutions. So think about which system can help you most and don’t hesitate to buy it, it’s investing for your own life.
