As an expert in the field of air filtration, I can confidently say that higher quality air filters do make a difference. Changing an air filter regularly can extend its lifespan and improve the air quality in your home. It is important to review the MERV rating of any filter you purchase, as this will tell you how well it can capture contaminants. A MERV rating of 16, which is often used in hospitals, is not necessary for a home environment and will increase energy costs.
Cheap air filters are only able to stop the largest particles, such as sand, hair, and dust. They are not designed to improve the air quality in your home. It is a myth that using a filter with a larger surface area will reduce the amount of work your HVAC system has to do. You should change your filters at least every season, or even once a month if necessary.
When selecting an air filter, you should consider the specific needs of your household occupants and choose one with an appropriate CADR or MERV rating. Disposable filters are made of pleated paper or polyester and provide a larger surface area for filtering. FilterBuy offers more expensive air filters for a reason - they are worth it for quality and comfort. However, these filters must be installed by trained professionals as they require changes to the ductwork and blower. When buying air filters online, look for places that allow you to customize your quantity to get exactly what you need.
Consider the difference between pleated and non-pleated filters and look for online retailers that offer discounts for recurring shipments of air filters. It is important to replace your filter regularly or there may be problems with air flow and filter effectiveness. These filters are installed in wall-mounted air return vents or on the air handler, depending on where you live. It is important to go to the store knowing what size of air filter you need for your system so that you don't leave empty-handed. When selecting an air filter, it is important to find the right balance between air filtration for your family's health, effective airflow, and energy efficiency. Higher quality air filters can stop biological contaminants, pet dander, dirt, mold spores, and other contaminants - making them worth the investment.
