When it comes to air filters, the quality of the filter does matter. It is essential to understand the different types of filters available and how they work in order to ensure the best air quality in your home. The most common type of air filter is the disposable fiberglass filter, which is usually rated at MERV 2 or 3.These filters are designed to protect the internal workings of the HVAC system, rather than to improve indoor air quality. They are also the cheapest option, but they don't do much to filter out dust, allergens, and other pollutants.
At the other end of the spectrum are high-efficiency filters, such as those rated at MERV 13.These filters are designed to stop bacteria, smoke, and other microscopic particles. They are more expensive than disposable fiberglass filters, but they can make a big difference in air quality. Another rating system is the Clean Air Supply Rate (CADR), which is recognized by the Federal Trade Commission and the Environmental Protection Agency. This scale measures the efficiency of air purifiers and can help you determine which filter is best for your needs.
You can also find smart filters on the market today, such as 3M's Filtrete smart air filters. These filters use sensors to monitor airflow and can help you maintain optimal air quality in your home. When it comes to replacing your air filter, you should consult the maintenance instructions for both your HVAC system and your specific filter. Generally speaking, you should replace your filter every three to 12 months, depending on its size.
You should also replace it at least once a season, if not once a month. It is important to remember that when it comes to air filters, quality does matter. Investing in a high-quality filter can make a huge difference in the air quality of your home and help keep your family healthy.
