Developed by a leading allergy and asthma specialist, AllergyZone XL 1500 Ultra Furnace Filters are uniquely designed to offer better overall performance as compared to many other filter choices. AllergyZone Filters have a MERV 12 efficiency rating, the highest rating awarded to filters for home use. AllergyZone’s specialized filtration media features a pleated design that allows the filter to attract and capture more particles compared to traditional flat filters. This air filter is so efficient, independent studies show it removes over 90% of harmful allergy-causing particles from the air, such as mold spores, pet dander, dust mite allergens and pollen grains.
AllergyZone’s filters provide sustained particulate capturing and excellent holding capacity while minimizing airflow resistance. Good air flow won’t cause a drain on your furnace or air handler and maintains a good air exchange rate to keep air circulating regularly. The filter media will not absorb moisture and will not support the growth of bacteria, mold, mildew or fungi. AllergyZone Furnace Filters are an excellent way to capture allergens and keep them from circulating through the vents in your home. Each disposable filter is designed for use up to 3 months, depending on the level of particulate in your home. Pack includes 4 disposable 1” filters. Choose from sizes 14×25, 16×20, 16×25, 20×20 and 20×25.
