To measure filter efficiency, experts use the minimum efficiency reporting value (MERV). MERV is a graph that classifies filters based on their ability to capture particles. The rating ranges from 1 to 16, and 16 are awarded to the types of air filters with the best filtering capacity. MERV ratings for different types of filters vary depending on their quality and manufacturer.
It is always mentioned on the package. Despite their popularity, these filters don't contribute much to indoor air quality. They can only filter about 20% of particles that are between 3.0 and 10.0 microns in size. Particles of this size only include dust, carpet fibers, and pollen.
The pleated filters consist of a medium fabric made of polyester or cotton. The material is organized in folds to increase the surface area of the filter. Therefore, filters that have more folds are more effective than those with fewer folds. These filters are slightly more expensive than fiberglass filters.
But they are also more effective against contaminants. They even capture smaller air pollutants, such as pollen, pet dander and mold spores. Pleated filters are available in reusable and disposable versions. Because of the high efficiency of these filters, they are popular among people who have an allergy to air conditioning or other respiratory problems.
However, these filters are more expensive than fiberglass filters and pleated filters. UV light filters kill bacteria and viruses with short-wave UV light. The germicidal radiation from the UV lamp in these filters disinfects the air in its path. They're also great for eliminating harmful microorganisms from your space, such as mold spores.
Second, while UV light filters remove bacteria and viruses from the air, they do little to combat contaminants such as dust. As a result, these filters are generally part of a more advanced filtration mechanism, such as HEPA filters. These filters create static electricity by using a mix of cotton and paper fibers. This static then acts like a magnet and traps contaminants inside the filter screen.
Because this prevents allergens from spreading in the home, electrostatic filters are ideal for people who have allergies. Electrostatic filters often also have a carbon filter to improve efficiency. This type of AC filter can be flat panel or pleated. They also come in washable and disposable versions.
Multimedia filters consist of a material similar to paper folded in folds inside a metal cabinet. While the filter is no larger than six inches, the pleated material can cover 75 square feet when unfolded. This larger surface area makes media filters seven times more effective than standard types of air filters. The large surface area also explains the extended lifespan of multimedia filters.
These filters can last up to 2 years, depending on the environment. Experts recommend that people who live in industrial areas or with a weak immune system opt for multimedia filters instead of other types of air conditioning filters. As a general rule, it is recommended to clean air conditioning filters every 250 hours of use. While this cleaning is essential, it can often go unnoticed on your to-do list.
We recommend using smart thermostats or smart AC controllers that send reminders when the next cleaning is due. People who live with allergies or other respiratory problems may benefit most from HEPA filters. These filters must be adjusted by a contractor to fit your specific HVAC system. By using small cotton and paper fibers, electrostatic filters create static that acts as a magnet for dust and other particles suspended in the air.
The magnetism is strong enough to prevent these particles from spreading throughout the house, making them one of the best options for those who need a filter that can combat allergens. An additional advantage of electrostatic filters is that they are available as disposable and reusable. When it's time to change the filters, you can decide whether to wash and reuse them or throw them away and buy new ones. While certain types of air filters come with reusable and disposable options, washable filters are an environmentally friendly way to save money.
The starting price of this type of air filter for air conditioning systems is high, but it should be considered an investment that will last for many years. The starting price is probably all you'll have to pay, since you can simply wash and reuse the filter over and over instead of buying new ones every few months. Washable filters must be well maintained to ensure that they work as they should. As one of the main types of air filters, they come with maintenance instructions that must be followed.
It is very important to ensure that the filter is completely dry before putting it back in. Even the smallest amount of moisture left over can cause mold and mildew to form in the filter and expel it into the air you breathe. When it comes to air filters for HVAC systems, media filters can offer more benefits than standard filters with high MERV ratings. Media filters provide the same level of filtration as a filter with a high MERV content, but they do so without the negative consequences of airflow or static pressure.
In contrast, media filters have a larger surface area, which successfully avoids significant static pressure and, at the same time, provides better filtration. Multimedia filters are very easy to maintain and are great for filtering bacteria and other small airborne contaminants. The filtered dirt is sealed in the filter, preventing it from returning to your home. Media filters are also robust and cost-effective, and should be changed as infrequently as once or twice a year.
The pleats of these filters give them an advantage over the pleatless options because they increase the surface area of the filter for better filtering. Filters with more folds will filter better than those with fewer folds, since they trap even the most difficult allergens and contaminants, such as pet dander and mold spores. Pleated filters are also available in reusable and disposable formats, and can help suppress HVAC fan noise. The downside of these filters is that they require your HVAC system to work a little harder to draw air through the unit, which can cause your HVAC system to lose efficiency sooner than expected.
Because pleated filters slightly improve your home's air quality, they're a reasonably priced option for people concerned about indoor air quality. When you buy HVAC filters, you'll likely find several options to choose from in different types. If you're thinking about switching to a more efficient filter, here's a simple guide to the four types of HVAC filters you'll find on the market. Air Pro Heating & Air Conditioning Inc.
The primary function of HVAC air filters is to remove harmful particles from the air as it flows through the system. It's one of the best types of air conditioning filters because it's cost-effective, disposable, and protects air conditioners and ovens from dirt. Let's take a look at each type of filter and its characteristics to determine the types that might be right for your home. Not all filters are made the same, so choosing the right filter depends on what you need to purify the air.
Even the smallest amount of moisture left over can cause mold and mildew to form in the filter and then remain in the space you breathe. If a washable filter is not maintained, its effectiveness will be reduced and it does not have a high MERV rating. While they can effectively filter dust and other pollutants from the air, they provide low air filtration and are less resistant to airflow. One potential danger of UV filters is that they can transform oxygen into ozone, which can be hazardous to health.
Indoor air quality is an important part of maintaining your health, and Home Climates is dedicated to offering an exaggerated service at reasonable prices to ensure your home stays comfortable. The right air conditioning filters can make the difference between congested air full of pollutants and air that is clean, healthy, and easy to breathe. Therefore, to choose the type of HVAC filter that is most suitable for your home, you must understand how well each type of filter material works. Filters with very high MERV indices are suitable for hospitals, smoking rooms and sick care units.
Finding and using the right filter in your facility can make all the difference for tenants and building employees. .
