Air filters come in many different sizes to suit the needs of all households. It is important to know what you need before you choose one. One size does not fit all; therefore, it is important to measure the room in which you plan to use the filter in. The size of the room will help to determine the type of filter that should be chosen. Also, the type of filter you choose will depend on the types of particles that are commonly found in your home.
A common alternative for allergy and respiratory sickness sufferers is HEPA (High Efficiency Particulate Air) air filters. The particulate 20x20x1 air filter functions by capturing dust, dander, pollen and other allergens that can trigger an asthma attack or other respiratory illness. These filters are usually found in the central part of the house or in bedrooms and basements. They work by capturing the allergens and pollen in the air without having to remove the particles from the air around you. Because they do not remove all of the allergens, they are not advisable for people who suffer from allergies or asthma.
HEPA air filters also remove bacteria, mold spores and other microorganisms that can be found in the air on a daily basis. Many people who suffer from respiratory illnesses choose this option because they are able to remove many of the particles in the air without using any chemicals or electricity. HEPA air filters are usually found in public facilities like hospitals and schools. They are recommended to be used in these locations because of the very high levels of exposure these locations have to airborne particles. A portable HEPA air filter can be carried with you and can cover a much larger area than a stand-up air filter. Portable air filters are also more affordable than stand-up filters.
Humidification air filters use a process called adsorption to remove particles from the air, preventing them from being re-absorbed into your lungs or evaporating into the air.
The humidifier will need to be replaced approximately once per year. A good air filter 16x25x1 will remove particles that would reach down and around your bed if it was not humid enough to keep you comfortable. A good humidifier will also remove dust mites and odors. This is an excellent way to reduce allergens.
You can buy air filters at your local hardware store or home improvement store. For the best results, purchase a HEPA filter and avoid purchasing air filters made of porous materials, such as plastic.
If you are looking for the HEPA air filters in a convenient package, purchase a stainless steel mesh filter.
MVA and MPVA air filters are the highest grade available and provide the best protection against airborne particles. MVA and MPVA air filters provide their users with their own individual energy efficiency rating based on the cubic foot of air they cover. Air filtration technology has advanced significantly in the past few years and has come a long way from the first air filters to the ones you have in your home today. When shopping for an air filter, make sure you find one that not only meets the standards set by the regulatory agencies in your state but one that also provides the protection you need.
