Size, MERV rating, and material: these are the three main factors to consider when selecting the right air filter for your home. Knowing the size of the filter your system needs is essential. Most filters have the size specifications labeled on their surface, but sometimes the measurements are rounded up. If you're buying a new model, use a measuring tape to get the exact width, height, and length of the unit you need.
Air quality needs vary from home to home. For example, if your home is heavily insulated, it may tend to trap pollutants. Likewise, people with respiratory problems and other allergies may need a higher-quality filter to efficiently purify the air. According to research, Americans spend approximately 90% of their time indoors.
Therefore, it is essential to have filters that guarantee high quality air for your specific respiratory needs. Quality air filters are necessary to keep your home comfortable and free of contaminants. The MERV rating is a number designated by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) to help you compare filters. The FPR also indicates what type of airborne contaminants are ideal for capturing each filter. Homes with smokers or pets also contain higher levels of indoor air pollutants and would require a higher quality filter.
You don't want to give up energy efficiency for the sake of filter efficiency; look for a balance between the two when choosing the best air filter.
Types of Air Filters
Fiberglass, polyester, washable, pleated and electrostatic filters offer different air filtering capabilities. Your intention should be to achieve the right balance between air filtration levels, air flow, and energy efficiency. HEPA filters restrict air flow considerably and must be combined with appropriate modifications to the air conditioning system or used in separate portable units. They can help provide cleaner, filtered air by capturing a high percentage of potentially harmful particles in the air (such as smoke, dust, pet dander, and allergens) as the air passes through the filter. However, one of the main advantages of thicker air filters with larger folds is that they don't need to be changed as often.Choosing The Right Air Filter
When selecting an air filter, it is important to consider size, MERV rating, material type and performance level.Make sure it fits you properly by taking out your current air filter and checking the size printed on the frame. There are many different types of air filters on the market and most are designed with specific needs in mind. To make sure you get the right fit for your system and your home, consider all these factors before making a purchase.
