This free troubleshooting video explains the benefits of using the Allergen Shield Plus air filter instead of the common furnace air filter.
The Allergen Shield Plus air filter removes impurities from the air and protects your heating and cooling equipment. A dirty filter can damage your furnace by restricting air flow, which can also reduce efficiency and increase utility costs. The Allergen Shield Plus is a commercial grade MERV 8 filter that is more efficient and offers less air flow restriction than the average air filter.
