When it comes to large systems, the Filtrete 10x20x1 AC oven air filter is the best choice. This electrostatic filter is one of the most affordable on the market and outperforms other non-electrostatic filters. It has a MERV 11 rating, which means it filters more than 90 percent of particles between 1 and 3 microns in size. It also has an FPR rating of 6, which means it captures common irritants such as dust, pollen, mold spores and dander.
For homeowners with no air quality issues who are more concerned with protecting the oven, the Filtrete MPR 300 Clean Living Basic dust filter is a great option. This pleatless filter provides sufficient airflow and has a MERV 5 rating, which is at the lower end. It is also certified by the Asthma and Allergy Foundation. If you need added protection from allergens, you should consider the Aerostar pleated air filter. This filter has a MERV rating of 8 and provides improved allergen and odor control.
Long-life oven filters, also known as annual oven filters, have more surface area to extend the time between filter replacements. It's important to remember that every furnace and filtration system is different, but a good rule of thumb is to replace filters every two months. This will help keep your HVAC system running efficiently and prevent it from overheating. When shopping for an oven filter, look for one with a high MERV rating and an FPR rating that fits your needs. The Asthma and Allergy Foundation can help you find the best filter for your home.
