When it comes to selecting the right air filter for your home, there are a few essential factors to consider. Size, MERV rating, and material are the three main elements that will determine the effectiveness of your system and filter. Unless you have a correctly sized household air filter, you won't be able to reap the full benefits of your system. If you suffer from allergies, such as asthma, a HEPA or electrostatic filter may be the best option for you.
These filters are designed to remove microscopic allergens from the air. On the other hand, if you're looking to increase the filtration efficiency of your air conditioning system, you'll need to find out the thickness of the filter. It's best to consult a professional for this information. The MERV standard is used to measure the performance of filters designed for forced air conditioning systems.
People with allergies, asthma, bronchitis, sinus problems, and lung problems should opt for a higher-quality filter as indoor air pollutants can cause these issues. Most home improvement stores sell air conditioning filters ranging from MERV 1 to MERV 13, although some models can reach up to MERV 16. Generally speaking, you should replace your filter every three to 12 months depending on its size. The MERV rating is designated by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) and helps you compare different filters. Some air filters have a MERV rating while others have a CADR rating which helps you determine the quality of the filter's performance.
Each type of air conditioner filter has its own unique function and responds to different needs. If you can't measure, experts sometimes suggest using a MERV 8 pleated filter as a safe option. Filters can last for several years but it's recommended that you change them regularly for maximum efficiency. High-quality filters may be slightly more expensive than cheap fiberglass filters but they are worth it as they provide better quality air and keep your air system functioning properly. Flat panel or pleated filters are an economical solution that won't break the bank. Poor ventilation of outdoor air can cause indoor air pollutants to accumulate inside which places greater pressure on your air system as it absorbs more particles.
To ensure that your home is properly ventilated and that your air system is working efficiently, it's important to choose the right air filter.
