Replacing the air filter in your home is an essential part of keeping your HVAC system running smoothly. But with so many different types of air filters available, it can be difficult to know which one is right for you. In this article, we'll discuss the different types of air filters, how to measure for the correct size, and how to choose the best filter for your home. The most important factor to consider when selecting an air filter is the MERV rating.
MERV stands for Minimum Efficiency Reporting Value and is a rating that measures the filtration capacity of an air filter. The higher the MERV rating, the more effective the filter will be at capturing airborne particles like dust, pollen, and smoke. The most popular residential HVAC filter sizes have a MERV 13 rating, which means they can stop bacteria, smoke, and other microscopic particles. If you don't have the old filter handy, you'll need to measure the intake vent to determine the actual size of the air filter. This is important because if you buy a filter that's too small or too large, it won't fit properly and won't be as effective.
To measure for the right size, use a tape measure or ruler to measure the length, width, and depth of the opening where the filter will go. Once you know what size filter you need, you can start looking at different types of filters. Fibreglass filters are made of spun glass and last an average of 30 days. They are inexpensive but don't capture as many air particles as other types of filters. Pleated filters are more expensive but last longer and capture more particles.
Electrostatic filters are even more expensive but are very effective at capturing particles. When choosing an air filter for your home, it's important to consider both cost and effectiveness. Filterbuy has a wide selection of standard air filter sizes with different MERV ratings and odor control options so you can find one that fits your budget and needs. It's also important to remember that if you have pets or live in an area with a lot of air pollution, you may need to replace your filter more often. Replacing your air filter regularly is an essential part of keeping your HVAC system running efficiently. By following these tips, you can make sure you choose the right replacement air filter for your home.
