We now know that Air Quality is a Huge factor for human health. A clean home can be a healthy home. There are several ways to keep air clean in a home that will not break the bank through filtering. The least costly is the filter. There are many types of filters made today and it can be confusing to determine the exact one to use. Every home has a different use pattern and therefore may need a different type or quality. The pleated filter is the most commonly sold today, but they are made for different air capture rates. In other words, some allow more or less air to pass through in an attempt to catch fine particles where others are made to only protect the HVAC equipment. One must determine their needs and choose accordingly. Many older homes were never designed to use any type of high capture filter and using them only hurts the system because of the lack of air flow. A system starving for air is an energy wasting machine. Also, the quantity of fine particles that a pleated filter traps tends to clog the filter very quickly, again starving the system for air. Most pleated filters can become clogged in a matter of days depending on their capture rate. We consumers are trained to replace a filter based on time and not filter failure. We recommend dating a filter, checking its condition in at least 30 days to determine its condition then making a determination as to how often it should be replaced.
