The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHARE) recommends a MERV 6 or higher filter for replacing an air conditioning unit. Most people opt for a MERV 8 filter, as it is able to remove contaminants from the air more effectively than lower MERV ratings. Hospitals typically use MERV 14 to MERV 20 filters. The style of the filter also affects its efficiency.
Common air filters include fiberglass filters, polyester filters, and ultra-efficient HEPA filters. Recently, there has been an innovation in air filters that allows for high MERV ratings (11 to 1) with a low pressure drop. When it comes to replacing your air conditioning unit, it is important to consider the type of filter you should use. The MERV rating of a filter is the most important factor in determining its efficiency in trapping particles in a single pass.
The higher the MERV rating, the denser and more tightly intertwined the fibers are in order to trap smaller particles. However, higher MERV ratings also restrict air flow more than filters with a low MERV content. How often you use your air conditioner and the type of filter or filters you use will determine how often you should change them. Available in a variety of sizes and usually at a lower price than similar competitors, this pleated electret filter captures just about everything you would breathe at home.
There are also visual cues you can consider when deciding whether to replace your oven filter. If the filter is clogged with dust or dirt, it is time to replace it. Additionally, if smoke-filled air is finding its way around the clogged filter and not through it, then it is time to install a new one. Replacing the air filter in your air conditioning system is one of the most important aspects of regular maintenance. Air filters are available at home improvement stores, as well as retailers such as Walmart, Target, and Amazon.
A central air conditioner filter is usually made of spun fiberglass or pleated paper or cloth, enclosed in a rectangular cardboard frame. Replacing air filters regularly is the most important thing you can do to keep your central air conditioner running efficiently. The air passes through the filter (or filters) and the filter material traps contaminants before they can circulate around the house. When selecting an air filter for your AC unit replacement, it is important to consider both the MERV rating and style of the filter. ASHARE recommends a MERV 6 or higher rating for residential use, while hospitals typically use MERV 14 to MERV 20. Recently, there has been an innovation in air filters that allows for high MERV ratings (11 to 1) with a low pressure drop. In conclusion, selecting the right type of filter for your AC unit replacement is essential for keeping your system running efficiently and effectively.
Consider both the MERV rating and style of the filter when making your selection. Air filters are available at home improvement stores, as well as retailers such as Walmart, Target, and Amazon.
