When it comes to improving air quality, a 4-inch air filter has a clear advantage over a 1-inch filter. It offers greater longevity, better airflow, and more effective filtration. So, if it fits your oven, then a 4-inch filter is the way to go. A 4-inch filter covers a wider range of MERV ratings than a 1-inch filter, with some overlap.
It can provide at least an 8 MERV rating, and even up to 16 MERV for maximum filtering potential. This means that it can capture supermicro contaminants such as bacteria, viruses, and dust particles. The thickness of an air filter is important for trapping pollutants and keeping them out of your home's indoor air supply. A 4-inch filter is much thicker than the 1-inch filters you can buy at the grocery store.
It has more surface area to trap contaminants, allowing for proper airflow and continuous removal of pollutants. When comparing a 1-inch filter to a 4-inch filter, you'll find that the coarser filter has several advantages. It produces more airflow and clogs less easily. However, you should be careful with the MERV rating - if it's too high, it can cause mechanical problems in your HVAC system.If you want to upgrade to a 4-inch filter, your HVAC technician can provide you with a new filter compartment or modify the existing one to accommodate the coarser filter.
You should check the filter every 1 or 2 months during heavy use and replace it when necessary.In conclusion, if improving air quality is a priority for you, then a 4-inch air filter is better than a 1-inch air filter. It will last longer and provide better filtration for your home.
